what is probability ?The odds that a happening will happen or a claim will be true is measured by probability theory, a branch od arithmetic. The probability of an item is a number between 0 but also 1, where about 0 represents how frequently the event is to occurring and 1 represents certainty. A risk is a numerical illustration of the possibility that a specific occurrence will take place. Probabilities may be expressed as percentages ranging from 0percent to 100% as well as from 0 to 1. the ratio of the number of outcomes to the proportion of occurrences in a whole set of equally plausible options that lead to a specific occurrence.
given
We'll choose x on the graph to represent the number of years since 1990 and y to represent the number of moose.
On the graph, there are two points: (4, 4290) and (8, 3850)
We can determine the slope of this line using the slope formula (m = [y2 - y1]/[x2 - x1]):
Replacement: m = (3850 - 4290)/(8 - 4)
m = -440/4 Solve the parenthesis's subtraction puzzles.
m = -110 Reduce the percentage
Since we know the line's slope, we can apply the point-slope formula (y - y1 = m[x - x1]) to determine the line's equation.
P(16) = 2970

A company makes computer chips from square wafers of silicon. It wants to keep the side length of a wafer very close to 15 mm and it wants to know how the area A(x) of a wafer changes when the side length x changes. Find A` (15) and explain its meaning in this situation.
Answers
A'(15) = 2 * 15 = 30.The meaning of A'(15) in this situation is that if the side length of the wafer changes by 1 mm, the area will change by 30 mm^2 when the side length is 15 mm.
The area A(x) of a square wafer is given by A(x) = x², where x is the side length of the wafer. The derivative of A(x) with respect to x, denoted A'(x), represents the rate of change of the area with respect to the side length. To find A'(15), we need to find the derivative of A(x) at x = 15.
A'(x) = 2x
Therefore, A'(15) = 2 * 15 = 30.
The meaning of A'(15) in this situation is that if the side length of the wafer changes by 1 mm, the area will change by 30 mm² when the side length is 15 mm. This means that for every 1 mm increase in the side length, the area of the wafer will increase by 30 mm², and for every 1 mm decrease in the side length, the area of the wafer will decrease by 30 mm².

Five years ago, a father was six times as old as his son. Two years hence, the age of the father will be 1 year more the three times then age of his son. Find their present ages.
Answers
Answer:
84
Step-by-step explanation:
Let's call the father's present age "F" and the son's present age "S".
Five years ago, the father's age was F - 5 and the son's age was S - 5.
According to the first statement, F - 5 = 6(S - 5), so F = 6S - 35.
Two years in the future, the father's age will be F + 2 and the son's age will be S + 2.
According to the second statement, F + 2 = 3(S + 2) + 1, so F = 3S + 7.
We can now substitute the first equation into the second:
3S + 7 = 6S - 28,
3S - 6S = -35 - 7 = -42,
-3S = -42,
S = 14.
Finally, the father's present age is F = 6S - 35 = 84.
Answer:
The dad is 35 and the son is 10
Step-by-step explanation:
Let f = the father's age
let s - the son's age
In the equations f-5 and s-5 represents the father and son's ages 5 years ago. f + 2 and s +2 represent the father and son's ages two years in the future.

Step-by-step explanation:
16px + 10q + 10px = 78x + 60
Solve for p.
Subtract 10 q from each side.
16px + 10q-10q + 10px = 78x + 60 -10q
16px + 10px = 78x + 60-10q

1. Given the image of the circle, identify the length of the radius, diameter, and circumference. Also, find the area. Make sure to show work (area and circumference) to receive credit. Choose a number for the diameter.
Answers
Answer:
Radius = 5 units
Diameter = 10 units
Circumference = 10π units
Area = 25π square units.
Step-by-step explanation:
i choose diameter.
Let's say the diameter of the circle is 10 units.
The radius of the circle can be found by dividing the diameter by 2:
Radius = Diameter / 2 = 10 / 2 = 5 units
The circumference of the circle can be found using the formula:
Circumference = 2πr = 2π * 5 = 10π units
The area of the circle can be found using the formula:
Area = πr^2 = π * 5^2 = 25π square units.
So, for a circle with a diameter of 10 units:
Radius = 5 units
Diameter = 10 units
Circumference = 10π units
Area = 25π square units.

The circumference of a circular glazed donut with rainbow sprinkles is 9.42 inches. What is the diameter and radius of the circular donut?
Answers
The formula for the circumference of a circle is given by 2 * pi * r, where r is the radius. If the circumference is 9.42 inches, then we can write the equation:
9.42 = 2 * pi * r
Solving for r, we get:
r = 9.42 / (2 * pi)
The diameter of the circle is equal to 2 * r, so:
d = 2 * r = 2 * (9.42 / (2 * pi)) = 9.42 / pi
So, the radius of the circular donut is approximately 3 inches, and the diameter is approximately 9.42 inches.

On Friday, Thomas the clown sells 16 balloons at the circus. Due to demand, Thomas charges three dollars more per balloon on Saturday. On Saturday, he sells 40 balloons. Let f represent the price of a balloon on Friday and let t represent the total amount he earns on both days combined.
a Write an equation to describe the relationship between the price of a balloon on Friday and the total amount earned.
b Determine the price of a balloon on Saturday if Thomas earns 400 dollars on Friday and Saturday.
Answers
The relationship between the price of balloons and the amount earned is 56f + 120 dollars
The price of the balloons if 400 dollars is earned on friday and saturday is 5 dollars on friday and 8 dollars on saturday
How to solve for the pricea) If f is the price of a balloon on Friday, then the price of a balloon on Saturday would be f + 3 dollars. The total amount Thomas earns on Friday would be 16 balloons * f dollars/balloon = 16f dollars. The total amount Thomas earns on Saturday would be 40 balloons * (f + 3 dollars/balloon) = 40f + 120 dollars. Hence, the total amount earned on Friday and Saturday would be 16f + 40f + 120 dollars = 56f + 120 dollars.
Therefore, the equation to describe the relationship between the price of a balloon on Friday and the total amount earned is: t = 56f + 120 dollars.
b) We are given that Thomas earns 400 dollars on Friday and Saturday, so we can set t = 400 dollars in the equation derived above:
400 = 56f + 120
Solving for f, we have:
280 = 56f
f = 5 dollars
The price of a balloon on Friday is $5, and the price of a balloon on Saturday would be f + 3 = 5 + 3 = $8.

A tank is full of water. Find the work required to pump the water out of the spout. (Use 9.8 m/s2 for g. Use 1000 kg/m3 as the density of water. Assume r = 6 m and h = 2 m.)
Answers
The work required to pump the water out of the spout is 70.9 * 10⁶ joules which is 71 M Joules approx.
Let the spherical tank be divided into a series of horizontal disks.
Let x be the height of each disk, g = gravity and p = density
Volume of each disk = πr2dx
Where r is the radius of each disk and dx is the thickness
By Pythagoras r² = 6² - x²= 36 -x²
Therefore Volume = π*(36-x²)*dx cubic metres
The distance each disk has to be lifted to escape the top of the spout = 2 + 6-x meters = (8-x)
Work needed to lift each disk to outlet = distance * mass where
mass = volume * density * gravity
= pi(36-x²)*p*g = 9800pi(36-x²)dx
dW = (8-x)* 9800pi(36-x²)dx
Since we have already accounted for the height of the spout, the work required is obtained by integrating the above expression from the bottom of the tank to the top. In other words, - 6 to + 6.
W = ⌠(8-x)*9800pi(36-x2)dx = 9800pi⌠[288 - 36x - 8x² +x³]dx
The odd terms evaluate to zero and we can rewrite the above as 2* I from 0 to 6.
W = 9800pi*2 [288x - 8x³/3] at x = 6 = 1152*19600π Joules = 22579200π joules = 70963200j

Evaluate ∫∫r(x+y)dxdy, where r is the rectangle in the xy plane with vertices (0,1), (1,0), (3,4)and (4,3).
Answers
The double integral [tex]\int\limits^a_b {(x+y)} \, dx dy[/tex]over the rectangle r with vertices (0,1), (1,0), (3,4) and (4,3) is equal to 22.
What do you mean by integration?Integration can be thought of as the reverse of differentiation, which is the process of finding the rate of change of a function at a given point.
There are two main types of integration: definite and indefinite integration. The process of integration can be represented symbolically as ∫ (the integral symbol) and the result of an integration is typically represented as an antiderivative. The fundamental theorem of calculus states that differentiation and integration are inverse operations, so the derivative of an antiderivative is the original function.
To evaluate the double integral [tex]\int\limits^a_b {} \, dx dy[/tex]over the rectangle r with vertices (0,1), (1,0), (3,4) and (4,3), we first need to find the limits of integration for x and y.
The x-coordinates of the vertices of the rectangle range from 0 to 4, so the limits of integration for x are 0 to 4. The y-coordinates of the vertices of the rectangle range from 1 to 4, so the limits of integration for y are 1 to 4.
So, the double integral becomes:
[tex]\int\limits^a_b {(x+y)} \, dx dy[/tex] = (2 × 4² + 8 × 4) - (2 × 1² + 8 × 1) = 32 - 10 = 22.
Therefore, the double integral [tex]\int\limits^a_b {(x+y)} \, dx dy[/tex] over the rectangle r with vertices (0,1), (1,0), (3,4) and (4,3) is equal to 22.

Because the mean is very sensitive to extreme values, it is not a resistant measure of center. By deleting some low values and high values, the trimmed mean is more resistant. To find the 10%
trimmed mean for a data set, first arrange the data in order, then delete the bottom 10% of the values and delete the top 10% of the values, then calculate the mean of the remaining values. Use the
axial loads (pounds) of aluminum cans listed below for cans that are 0.0111 in. thick. Identify any outliers, then compare the median, mean, 10% trimmed mean, and 20% trimmed mean.
248 260 267 273 276 278 282 284 284 285
287 287 290 290 293 295 296 299 311 501
Answers
Step-by-step explanation:
Outliers: In this data set, the value of 501 is an outlier as it is significantly higher than the other values.
Median: To find the median, we arrange the data in order and find the middle value. In this case, since there are an odd number of values, the median is the middle value: 290.
Mean: To find the mean, we add up all the values and divide by the number of values:
(248 + 260 + 267 + ... + 311 + 501) / 21 = 293.67
10% Trimmed Mean: To find the 10% trimmed mean, we delete the bottom 10% of the values (2 values) and the top 10% of the values (2 values) and then find the mean of the remaining values:
(278 + 282 + 284 + 284 + 285 + 287 + 287 + 290 + 290 + 293 + 295 + 296 + 299 + 311) / 15 = 286.87
20% Trimmed Mean: To find the 20% trimmed mean, we delete the bottom 20% of the values (4 values) and the top 20% of the values (4 values) and then find the mean of the remaining values:
(284 + 284 + 285 + 287 + 287 + 290 + 290 + 293 + 295 + 296 + 299 + 311) / 12 = 288.92
The median, mean, 10% trimmed mean, and 20% trimmed mean can be compared to see how resistant each measure is to outliers. The median is the most resistant measure as it only considers the middle value, whereas the mean is the least resistant measure as it considers all values in the data set. The trimmed means are intermediate measures that are more resistant to outliers than the mean but less resistant than the median. In this case, we can see that the 10% trimmed mean is more resistant to outliers than the mean but less resistant than the 20% trimmed mean.

Cooking time 35 minutes to be ready for lunch at 13:00, calculate what time the item should be put in the oven.
Answers
Answer:
he item should be put in the oven at 12:25 (in 24-hour format) to be ready for lunch at 13:00.
Step-by-step explanation:
To calculate what time the item should be put in the oven, you need to work backwards from the desired serving time of 13:00 and subtract the cooking time of 35 minutes. Here's how you can do it:
Convert the serving time to 24-hour format: 13:00 is the same as 1:00 PM in 12-hour format. In 24-hour format, it is 13:00.
Subtract the cooking time: Subtract 35 minutes from the serving time of 13:00 to get the time when the item should be put in the oven.
13:00 - 00:35 = 12:25
So, the item should be put in the oven at 12:25 (in 24-hour format) to be ready for lunch at 13:00.
Determine which of the lines are skew
Answers
The lines are skew is Lines AD and BF.
Definition of Skew lineSkew lines are two lines that do not intersect, are not parallel, and are not coplanar. This means that the skew lines never cross and are not parallel to each other. For lines to be two-dimensional or coplanar, they can intersect or be parallel. This property does not apply to diagonal lines, which are always non-coplanar and exist in three or more dimensions.
Skew line exampleIn real life, cities have different types of roads, such as highways and overpasses. These streets are supposed to be on different levels. Lines drawn on such roads never intersect, creating skew lines instead of being parallel to each other.

What in mathematics is a linear equation?
An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.
The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times. Equations with variables of power 1 are referred to as linear equations. One example with only one variable is where ax+b = 0, where a and b are real values and x is the variable.
