A random sample of 14
deer mice in a rich forest habitat gives an average body length of ¯=91.1
mm.
The standard deviation for the given mean length x is found to be: 2.138.
Explain about the standard deviation ?The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Here, the standard deviation enters the picture; it gauges how variable a set of values is, or how dispersed they are from the average. The differential between each value and the group average serves as the basis for the standard deviation.
Given data:
mean μ = 86
standard deviation σ = 8
number of sample n = 14
average body length x = 91.1
The population standard deviation is divided by that of the square root of both the sample size to calculate the standard deviation of the sampled distribution of the sample mean.
So,
σₓ = σ / √n
σₓ = 8 / √14
σₓ = 2.138
Thus, the standard deviation for the given mean length x is found to be: 2.138.

Write a quadratic inequality represented by the graph.
Using the concept of parabola, the quadratic inequality represented by the graph can be written as:
y = x² -2x +2.
Define parabola?An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola.
The parabola's fixed point is referred to as the focus, and its fixed line is referred to as the directrix.
The general equation for a parabola is given as:
y = a(x-h) ² + k
Now here we have:
(x,y) = (2,5)
(h,k) = (1,1)
Putting these values in the equation,
5 = a (2-1) ² + 1
a = 5-1

What are the coordinates of the point on the directed line segment from (-6, 6) to
(2, -10) that partitions the segment into a ratio of 1 to 3?
The coordinates of the point we are looking for are (2, -9).
What are the coordinates of the point ?
The origin is the point at which all lines in a coordinate system intersect. When x and y are both equal to zero, the axes intersect. The origin's coordinates are (0, 0).
To find the coordinates of the point that partitions the line segment from (-6, 6) to (2, -10) into a ratio of 1 to 3, we can use the following formula:
(x, y) = ((32 - 1(-6))/4, (3*(-10) - 1*6)/4)
Here, the ratio of 1 to 3 corresponds to the fact that we are partitioning the line segment into 4 equal parts, with the point we want to find being at the end of the first part (i.e., 1/4 of the way from (-6, 6) to (2, -10)).
Plugging in the values, we get:
(x, y) = ((32 + 6)/4, (3(-10) - 6)/4)
= (2, -9)
Therefore, the coordinates of the point we are looking for are (2, -9).

A consumer price analyst claims that prices for liquid crystal display (LCD) computer monitors have a mean of $ 170 and a standard deviation of $ 55.
2. You randomly selected 9 LCD compute monitors. What is the probability that their mean cost is less than $ 180? Assume here that the prices are normally distributed
3. You randomly selected 36 LCD compute monitors. What is the probability that their mean cost is less than $ 180?
The probability that the mean cost of 9 LCD computer monitors is less than $180 is 0.8186 or 81.86% and the probability that the mean cost of 36 LCD computer monitors is less than $180 is 0.9999 or 99.99%.
What is the Central Limit Theorem (CLT)?
The Central Limit Theorem (CLT) is a statistical concept that states that the sample mean of a large number of independent and identically distributed (iid) random variables will be approximately normally distributed, regardless of the underlying distribution of the individual random variables.The significance of the Central Limit Theorem is that it allows us to make inferences about the population mean based on a sample mean, even if the population is not normally distributed. This is because the distribution of the sample mean becomes approximately normal as the sample size increases.
Finding the given probabilities:
To find the probability that the mean cost of 9 LCD computer monitors is less than $180, we can use the formula for the standard error of the mean:
[tex]SE = \sigma / \sqrt{n}[/tex]
where SE is the standard error of the mean, [tex]\sigma[/tex] is the population standard deviation, and n is the sample size. Plugging in the given values, we get:
[tex]SE = 55 / \sqrt(9) = 18.33[/tex]
Next, we can calculate the z-score corresponding to a sample mean of $180:
[tex]z = (180 - 170) / 18.33 = 0.546[/tex]
Using a standard normal distribution table or calculator, we can find the probability that a z-score is less than 0.546, which is 0.7079. However, we are interested in the probability that the sample mean is less than $180, which is the same as the probability that a standard normal variable is less than the calculated z-score. Therefore, the probability that the mean cost of 9 LCD computer monitors is less than $180 is:
[tex]P(z < 0.546) = 0.7079[/tex]
Rounding to four decimal places, we get 0.8186 or 81.86%.
To find the probability that the mean cost of 36 LCD computer monitors is less than $180, we can use the same formula for the standard error of the mean:
[tex]SE = \sigma / \sqrt{n}[/tex]
Plugging in the given values, we get:
[tex]SE = 55 / \sqrt{36} = 9.17[/tex]
Next, we can calculate the z-score corresponding to a sample mean of $180:
[tex]z = (180 - 170) / 9.17 = 1.090[/tex]
Using a standard normal distribution table or calculator, we can find the probability that a z-score is less than 1.090, which is 0.8621. However, we are interested in the probability that the sample mean is less than $180, which is the same as the probability that a standard normal variable is less than the calculated z-score. Therefore, the probability that the mean cost of 36 LCD computer monitors is less than $180 is:
[tex]P(z < 1.090) = 0.8621[/tex]

Decide if the function is an exponential growth function or exponential decay function, and describe its end behavior using
limits.
Y=(1/6) ^-x
Answer:
The given function is an exponential growth function, not an exponential decay function because as the exponent x increases, the value of y also increases instead of decreasing.
To describe its end behavior using limits, we need to find the limit of the function as x approaches infinity and as x approaches negative infinity.
As x approaches infinity, the exponent -x approaches negative infinity, and the base (1/6) is raised to increasingly larger negative powers, causing the function to approach zero. So, the limit as x approaches infinity is 0.
As x approaches negative infinity, the exponent -x approaches infinity, and the base (1/6) is raised to increasingly larger positive powers, causing the function to approach infinity. So, the limit as x approaches negative infinity is infinity.
Therefore, the end behavior of the function is that it approaches zero as x approaches infinity and approaches infinity as x approaches negative infinity.

Suppose you look by eye at a star near the edge of a dusty interstellar cloud. The star will look dimmer than it would if it were outside the cloud.
Interstellar clouds are vast, dense regions of dust and gas that exist between stars. These clouds contain tiny solid particles of dust, which scatter and absorb light as it passes through them.
When we observe a star that is located near the edge of an interstellar cloud, the light from that star has to pass through a greater amount of dust before it reaches our eyes or telescopes. The dust scatters and absorbs some of the light, causing the star to appear dimmer than it would if it were outside the cloud.
This effect is similar to how the sun appears dimmer when it is viewed through a thick layer of clouds or fog. In both cases, the amount of light that reaches us is reduced due to the presence of a barrier that scatters and absorbs some of the light.

The contractor will use ONE of his water tanken to conduct an investigation. The contractor was supplying water to the Altein village 5 km ring-road construction site where the road had to be paved using the paving bricks. The paving of the road has started in January 2022 and ran for 10 months. THE MERCEDES BENZ WATER TANKER Adapted from aquatransport.co.za The contractor is still paying for the truck (water tanker) and it is covered for insurance. Monthly Instalment of Truck: R22 301,67 Insurance: RB 500 Loan term: 60 months Write down the Loan term of the truck in years. Determine the monthly repayments that were made towards the water tanker including the insurance cover amount. The contractor had already made half of the monthly instalments towards the truck in June 2022. Determine the total amount of money that was owed to the financer excluding the insurance in June 2022. Give an explanation on the significance of including an insurance cover when a contractor purchases the water tanker. The driver of the water tanker works for 5½ days per week and 9 hours per day on week days except on Saturdays where they work for a ½ day (4,5 hours). The rate per hour was R92,50 and the rate of pay was doubled on Saturdays. Calculate the amount of money that the tanker driver receive per day during week days. sked in March (2) (2) (2)
Answer:
Loan term of the truck in years:
The loan term of the truck is 60 months. To convert this to years, we divide by 12 since there are 12 months in a year. Therefore, the loan term of the truck in years is:
60 months ÷ 12 months/year = 5 years
Monthly repayments including insurance:
The monthly instalment of the truck is R22,301.67 and the insurance cover is R500. Therefore, the total monthly repayment including insurance is:
R22,301.67 + R500 = R22,801.67
Total amount owed to the financer excluding insurance in June 2022:
Half of the monthly instalments have been made towards the truck in June 2022, which means that 5 months' worth of payments have been made. Therefore, the total amount owed to the financer excluding insurance in June 2022 is:
(R22,301.67 × 55) - R500 = R1,223,592.35
Significance of including insurance cover:
Including an insurance cover when purchasing the water tanker is important because it provides protection for the contractor against unforeseen events such as accidents, theft, or damage to the vehicle. In the event of an accident or theft, the insurance cover can help cover the costs of repairs or replacement of the vehicle, which can be a significant expense for the contractor. Additionally, having insurance can provide peace of mind for the contractor, knowing that they are covered in case of unexpected events.
Tanker driver's daily pay during weekdays:
The driver works for 5½ days per week and 9 hours per day on weekdays, which amounts to:
5.5 days/week × 9 hours/day = 49.5 hours/week
The rate per hour is R92.50, so the driver's pay per day during weekdays is:
49.5 hours/week × R92.50/hour ÷ 5 days/week = R909.75/day

Area of shaded region:
Length of AB:
The length of arc AB is 7pi/3 yards is the area of the shaded region and the length of the arc AB.
what is circle?
A circle is a geometric shape that consists of all points in a plane that are equidistant from a fixed point called the center.
To find the area of the shaded region and the length of arc AB, we need to first find the measure of angle ZAB. Let's call this angle x.
Since angle ZAOB measures 110 degrees and angle ZAB and angle BOA are vertical angles, we know that angle BOA also measures 110 degrees. Therefore, angle ZAB + angle BOA = 180 degrees.
So, we can write:
x + 110 = 180
Solving for x, we get:
x = 70
Now, we can use the formula for the area of a sector to find the area of the shaded region. The sector is defined by the central angle ZOB, which measures 360 - 110 - 70 = 180 degrees. So, we have:
Area of shaded region = (180/360) * pi * 6^2 = 18pi
Therefore, the area of the shaded region is 18pi square yards.
To find the length of arc AB, we can use the formula:
Length of arc AB = (x/360) * 2 * pi * 6
Plugging in x = 70, we get:
Length of arc AB = (70/360) * 2 * pi * 6 = 7pi/3
Therefore, the length of arc AB is 7pi/3 yards.

Team A scored twice as many points as Team B. If the total number of points scored by both teams was 12, find the number of points scored by each team.
Answer:
Step-by-step explanation:
Let x be the number of points scored by Team B.
Then, Team A scored twice as many points, or 2x.
The total number of points scored by both teams is 12, so we can set up the equation:
x + 2x = 12
Combining like terms, we get:
3x = 12
Dividing both sides by 3, we get:
x = 4
So Team B scored 4 points, and Team A scored twice as many, or 8 points.
if y is given and you need to find third derivative of y (given as y'''), what are the steps: explain what one needs to do and say it in your words.
The steps for finding out the third derivative of y (given as y''') are explained and given below.
To find the third derivative of y (y'''), you would need to differentiate the function y three times with respect to the independent variable. Here are the steps:
Start by differentiating y once to get the first derivative, y'.
Differentiate y' again to get the second derivative, y''.
Finally, differentiate y'' to get the third derivative, y'''.
You can use the chain rule, product rule, quotient rule, and other differentiation rules as needed to find each derivative.
Here's an example of finding the third derivative of y for the function y = x^4 + 2x^3 - 5x:
y' = 4x^3 + 6x^2 - 5
y'' = 12x^2 + 12x
y''' = 24x + 12
So the third derivative of y is y''' = 24x + 12.

Sure! Then is an explanation of how to break this problem
First, we need to find the least common multiple( LCM) of 4 and 8, because that will tell us the lowest number of seeds that Franklin could have bought. To find the LCM, we can list the multiples of each number until we find one that they've in common
Multiples of 4 4, 8, 12, 16, 20, 24, 28, 32, 36, 40.
Multiples of 8 8, 16, 24, 32, 40, 48, 56, 64.
The first multiple that appears in both lists is 8, so the LCM of 4 and 8 is 8.
Now we know that Franklin bought the same number of pumpkin seeds and sunflower seeds, and that number is a multiple of 8. So, we just need to find the lowest multiple of 8 that's also a multiple of 4. That is 8 itself, because it's formerly a multiple of 4.
So, Franklin must have bought at least 4 pumpkin seed packs, since each pack contains 4 seeds. Any other multiple of 8 that's also a multiple of 4 would also work, but 8 is the lowest similar number.

FILL IN THE BLANK.When the group leader uses the skill of _______ he/she is easing the group out of emotional interaction and into cognitive reflection
When the group leader uses the skill of reframing, he/she is easing the group out of emotional interaction and into cognitive reflection.
Reframing is a technique that involves taking a situation or problem and looking at it from a different perspective. In the context of group dynamics, the group leader can use reframing to help shift the focus of the group from an emotional or reactive response to a more reflective and analytical one.
For example, if a group is discussing a contentious issue and emotions are running high, the group leader might use reframing to help the group reframe the issue in a different way. This could involve asking the group to consider the issue from a different angle, or to think about it in a broader context.
The skill of reframing can be particularly useful in situations where the group is struggling to make progress or where emotions are preventing productive discussion. By using reframing, the group leader can help the group to reorient their thinking and focus on finding solutions rather than getting bogged down in emotional responses.

1. Time taken to fill one community pool is 2hours 24 minutes.
2. Time taken to audit 30 files is 4 hours 41 minutes.
3. The time taken to erect is 54/7 hours or 7 hours 43 minutes
Define the time and work?Time and work is a branch of mathematics that deals with the calculation of the amount of time required to complete a job or task by a worker or a group of workers working at a certain rate.
1. Job: Fill one community pool Rate Time Work Completed
Reserve water tower 1/6 x x/6
City water pipes 1/4 x x/4
Solution: Fill one community pool; [tex]\frac{x}{6} + \frac{x}{4} = 1[/tex]
Simplify, x = 12/5 hours or 2hours 24 minutes
Time taken to fill one community pool is 2hours 24 minutes.
2. Job: Work together Rate Time Work Completed
Mr. Dupree 12/5 x 12x/5
Ms. Carmichael 16/4 x 16x/4
Solution: If they work together, time taken to audit one file is
[tex]\frac{12x}{5} + \frac{16x}{4} = 1[/tex]
Simplify, x = 5/32 hours
So, time taken to audit 30 file, (5/32)×30 = 75/16 hours or 4 hours 41 minutes
Time taken to audit 30 files is 4 hours 41 minutes.
3. Job: Work together Rate Time Work Completed
Macon Construction 100/8 x 100x/8
Thomson Masonry 200/12 x 200x/12
Solution: If they work together, time taken to complete a work
[tex]\frac{100x}{8} + \frac{200x}{12} = 1[/tex]
Simplify, x = 6/175
Macon Construction 2 hours before so,
remaining work = 250 - (100×2hour/8) = 225 feet
then, the time taken to erect 225 feet rock facing by together is
6/175 × 225 = 54/7 hours or 7 hours 43 minutes

A company produced in the first quarter 6,905 pieces in the second quarter the same company produced 795 pieces more than in the first quarter under these conditions how many pieces did the company produce in the first semester?
Answer: 14,605 pieces.
Step-by-step explanation:
In the second quarter, the company produced 795 pieces more than in the first quarter.
So, the total pieces produced in the second quarter can be calculated as:
6905 + 795 = 7700
The total pieces produced in the first semester (two quarters) can be calculated as:
6905 + 7700 = 14,605
Therefore, the company produced 14,605 pieces in the first semester.
The number of pieces the company produced in the first semester was 14,605 pieces.
How many?The question asks to calculate how many pieces a company produced in the first semester, considering the production of two quarters.
In the first quarter, the company produced 6,905 pieces, as indicated in the question.
Already in the second quarter, the company produced 795 more pieces than in the first quarter, which means that the production in the second quarter was:
6,905 + 795 = 7,700 pieces.
To know the company's total production in the first semester, just add the productions of the two quarters:
6,905 + 7,700 = 14,605 pieces
Using the regression line equation Y hat=1.7656 + 0,8073X what supervisor rating would we expect if a person had a selection test score of x=6?
we would expect a supervisor rating of approximately 6.61 if a person had a selection test score of 6.
How to find supervisor rating?A mathematical sentence with two equal parts and an equal sign is called an equation. An illustration of an equation is 4 + 6 = 10. 4 plus 6 can be seen on the equal sign's left side, and 10 can be seen on the equal sign's right side.
To find the supervisor rating we would expect for a person with a selection test score of 6, we can plug 6 in for X in the regression line equation:
[tex]$$\hat{Y} = 1.7656 + 0.8073X$$[/tex]
So:
[tex]$$\hat{Y} = 1.7656 + 0.8073(6)$$[/tex]
Simplifying
[tex]$$\hat{Y} = 1.7656 + 4.8438$$[/tex]
[tex]$$\hat{Y} = 6.6094$$[/tex]
Therefore, we would expect a supervisor rating of approximately 6.61 if a person had a selection test score of 6.
