Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find the probability of obtaining a reading greater than -1.12°C.
The probability of getting a measurement above -1.12°C is 0.8686, or almost 87%.
The probability formula is what?Typically, the probability is defined as the ratio of favorable events to all other outcomes in the sample space.Probability of an event P(E) = (Number of favorable outcomes) is how it is stated (Sample space).
We must determine the area under the normal distribution curve to the right of -1.12°C in order to determine the likelihood of getting a reading higher than that value.
We may convert the value of -1.12°C to a z-score, which represents the amount of standard deviations from the mean, using a calculator or a typical normal distribution table:
z = (x - μ) / σ
z = (-1.12 - 0) / 1.00
z = -1.12
The area under the normal distribution curve to the right of a particular z-score can also be found using a calculator. For instance, we can type the following into a calculator that has a normal distribution function:

algebraically determine the values of x that satisfy the system of equations below
The solutions to the system of equations are (x,y) = (0,1) and (5/2,3)
What is Algebraic Equations?
An algebraic equation is also known as a polynomial equation because both sides of the equal sign contain polynomials. An algebraic equation is built up of variables, coefficients, constants as well as algebraic operations such as addition, subtraction, multiplication, division, exponentiation, etc.
To solve the system of equations algebraically, we can set the two expressions for y equal to each other and solve for x:
[tex]-2x + 1 = -2x^2 + 3x + 1[/tex]
Simplifying, we get:
[tex]-2x^2 + 3x + 1 + 2x - 1 = 0[/tex]
[tex]-2x^2 + 5x = 0[/tex]
Factorizing x, we get:
x(-2x + 5) = 0
Therefore, the solutions for x are:
x = 0 or x = 5/2
To find the corresponding values of y, we can substitute these values of x into either of the original equations for y:
For x = 0:
y = -2(0) + 1 = 1
For x = 5/2:
[tex]y = -2(5/2)^2 + 3(5/2) + 1 = -13/2 + 15/2 + 1 = 3[/tex]
Therefore, the solutions to the system of equations are:
(x,y) = (0,1) and (5/2,3)

The resultant force is equal to F1, which is {-300i + 170j + 190k}N, and the couple moment acting at point 0 is (-0.19i - 0.34j + 0.15k) N.m.
To determine the resultant force acting at point O, we can add all the forces acting at point O. In this case, we have only one force F1 = {-300i + 170j + 190k}N. Therefore, the resultant force acting at point O is F1 itself.
To determine the couple moment acting at point O, we can use the formula:
M = r x F
where r is the position vector from point O to any point on the line of action of force F.
Since we don’t know the position vector r, we can choose any arbitrary point on the line of action of force F. Let’s say we choose point A which lies on the line of action of force F and is perpendicular to it.
Therefore, r = OA where OA is the position vector from point O to point A. We can find OA by subtracting position vectors of points O and A i.e., OA = A - O.
Now, let’s calculate M using M = r x F.
M = (OA) x F1
M = (A - O) x {-300i + 170j + 190k}N M

(a) 7.97E33 = 7.97 x 10^33
(b) 7.6E-37 = 7.6 x 10^-37
Step-by-step explanation:
In scientific notation, a number is written as the product of a decimal number between 1 and 10 and a power of 10. The decimal number is called the mantissa, and the power of 10 is called the exponent. The mantissa indicates the significant digits of the number, while the exponent tells us the size of the number relative to 1. In the given calculator computations, the numbers are already written in scientific notation, where "E" represents the exponent notation. We just need to convert them into the standard form of scientific notation by expanding the notation as a product of the mantissa and the power of 10.
A rectangular fish tank 60 cm x 15 cm x 34 cm is 13 full of water. Find the volume of water needed to fill the tank completely.
Step-by-step explanation:
The volume of the rectangular fish tank is:
V = l x w x h = 60 cm x 15 cm x 34 cm = 30,600 cm³
Since the tank is 1/3 full, the volume of water in the tank is:
V_water = (1/3) x V = (1/3) x 30,600 cm³ = 10,200 cm³
To find the volume of water needed to fill the tank completely, we can subtract the volume of water already in the tank from the total volume of the tank:
V_needed = V - V_water = 30,600 cm³ - 10,200 cm³ = 20,400 cm³
Therefore, 20,400 cm³ of water is needed to fill the tank completely.
What is the amount of interest to be paid if u got a reducing balance loan of $2700 and you will repay it over 5 years by quarterly installments of $1899.75 at interest rate 14% p.a. (compounded quarterly)
The total interest to be paid over the 5-year period is $403.22.
What is reducing balance loan?In a loan with a declining balance, interest is added to the outstanding balance at the start of each period, such as each month or each quarter. The outstanding balance, which decreases as the borrower makes repayments, is used to determine the interest rate. As a result, the borrower gradually pays less interest and more of each payment is used to lowering the main balance due. The lowering balance approach is frequently applied to mortgages, personal loans, and auto loans.
Given that, the quarterly installments are $1899.75.
For the entire year for a total of 5 years the total amount is:
Total amount = 4 * 5 * $1899.75 = $37995
For reducing balance loan the interest is calculated as:
For the first quarter, the interest to be paid is:
interest = (total amount - 0) * (0.14 / 4)
interest = (37995 - 0) * (0.14 / 4) = $94.50
Similarly for the remaining quarters we have:
Second quarter = $87.95
Third quarter: $81.05
Fourth quarter: $73.76
Fifth quarter: $65.96
The total interest to be paid over the 5-year period is:
$94.50 + $87.95 + $81.05 + $73.76 + $65.96 = $403.22
Hence, the total interest to be paid over the 5-year period is $403.22.

Give a reason for your answer to the following question. Assume that all variables represent integers.
If n = 4k + 3, does 8 divide n2 − 1?
Yes, 8 divides n^2 - 1 when n = 4k + 3.
We are given that n = 4k + 3, where k is an integer. We want to determine if 8 divides n^2 - 1, which means we want to know if there exists an integer m such that n^2 - 1 = 8m.
To start, we can rewrite n^2 - 1 as (n + 1)(n - 1). This is a common trick in number theory problems involving divisibility, and it can often help us factorize expressions in a useful way.
Substituting n = 4k + 3, we get:
(n + 1)(n - 1) = (4k + 3 + 1)(4k + 3 - 1) = (4k + 4)(4k + 2)
Now, we want to determine whether 8 divides this expression. In other words, we want to know if there exists an integer m such that:
(4k + 4)(4k + 2) = 8m
We can simplify the left-hand side of this equation by factoring out 4
4(k + 1)(2k + 1) = 8m
Now, we see that 8 divides the left-hand side of the equation, since it is equal to 4 times an even number. Moreover, (k + 1) and (2k + 1) are both integers, so we can conclude that 8 divides n^2 - 1 when n = 4k + 3.

and 40% on rural roads. If out of a sample 100 accidents investigated, the number of accidents
on highways was 80 and rural roads 20. Determine the number of accidents on highways and
rural roads after 4 years.
Answer: To determine the number of accidents on highways and rural roads after 4 years, we need more information. The given data only tells us about the distribution of accidents in a sample of 100 accidents investigated, but it doesn't provide any information about the rate of change or trend of accidents over time.
Assuming that the rate of accidents on highways and rural roads remains the same, we can make a projection based on the given data. If 60% of the road accident deaths occur on highways and 40% on rural roads, we can estimate the number of accidents on highways and rural roads after 4 years as follows:
Number of accidents on highways after 4 years = 80 * (100/60) = 133.33 (rounded to 133)
Number of accidents on rural roads after 4 years = 20 * (100/40) = 50
Note that this is only a projection based on the assumption that the rate of accidents remains the same. In reality, the number of accidents can vary depending on various factors such as changes in traffic volume, weather conditions, road infrastructure, and driver behavior, among others. Therefore, this projection should be taken as an estimate and not as an accurate prediction.
Step-by-step explanation:
A worker earning an hourly wage changes positions within a company. The new position comes with a 20% raise in hourly wage. The
worker also receives a $2 increase in hourly wage. Use composition of functions to write a function that represents the worker's new
hourly wage when the 20% raise is applied before the $2 raise.
f(x) =
This function gives the same result as the previous function we derived, but it expresses the calculation as a composition of the two separate functions that represent each raise separately.
What is function?A function is a set of instructions or statements that perform a specific task or computation and returns a value or result. In programming, a function is typically defined using a specific syntax and can be called or invoked by other parts of the program to carry out a particular operation.
Functions are used in programming to break down complex tasks into smaller, more manageable pieces of code, which can then be reused in multiple parts of the program. They can also help to improve the organization, readability, and maintainability of code.
by the question.
let the worker's original hourly wage be represented by the variable x. Then the function for the worker's new hourly wage when the 20% raise is applied before the $2 raise can be expressed as follows:
[tex]f(x) = (1.20x) + 2[/tex]
In this function, the expression (1.20x) represents the worker's hourly wage after the 20% raise is applied, and the additional $2 raise is added to this amount to determine the final hourly wage.
We can also express this function using function composition notation. Let g(x) represent the function that applies the 20% raise to the worker's hourly wage and let h(x) represent the function that adds the $2 raise to the resulting hourly wage. Then we have:
[tex]g(x) = 1.20x[/tex]
[tex]h(x) = x + 2[/tex]
Using function composition, we can write the function for the worker's new hourly wage as:
[tex]f(x) = h(g(x)) = h(1.20x) = 1.20x + 2[/tex]

Determine whether the function is linear. If it is, identify the rate of change. X -7, -5, -3, -1, 0 Y 11, 14, 17, 20, 23
Answer: Yes;
Step-by-step explanation: The function is linear in that the X values are increasing by 2 and the Y values are increasing by 3.
Answer:
Not linear
Step-by-step explanation:
X | -7 | -5 | -3 | -1 | 0
Y | 11 | 14 | 17 | 20 | 23
-5 - (-7) = +2
14 - 11 = +3
-3 - (-5) = +2
17 - 14 = +3
-1 - (-3) = +2
20 - 17 = +3
0 - (-1) = +1
23 - 20 = +3
There is a linear function graphed that would pass through the first 4 points, but not the last one;
You can discern this as there is a common pattern we can identify, everytime the x-value increases by 2 the y-value increases by 3, except with the last coordinates;
The rate of change, also known as the gradient, is the change in x divided by the change in y (Δx/Δy);
In the case of the first 4 points, the rate of change would be 3/2 or 1.5;
This simply means when x increases by 1, y increases by 1.5, IF the function is linear;
However, as mentioned the last point doesn't fit the pattern;
There, we can see the y-value increases by 3 when the x-value only increases by 1;
This means the point (0, 23) isnt on the graph of the function, the points (0, 21.5) and (1, 23), on the other hand, would be.
in a popular shopping Centre waiting time for an ABC bank ATM machine is found to be uniformly distributed between 1 and 5 minutes what is the probability of waiting between 2 and 4 minutes to use the ATM
so here we get two outcomes one is 2 and other is 4.
so there is total 2 outcomes.
total no. of possibility is 5
so the probability of waiting between 2 and 4 minutes to use the ATM is 2/5.
find the center and radius of the circle whose equation is x^2+y^2+4x+12y =-15
Answer:
center: (-2,-6)
radius: 5
Step-by-step explanation:
You have to complete the square again. This time the x's and the y's both need work. So first, organize. Put the x's together and put the y's together. Leave a little room to work. Take the x term and the y term and CUT them in HALF and Square 'em. That is what you add in to complete the square. Add the same thing to both sides.

My cookbook's pancake recipe states that it makes 12 standard sized pancakes. The nutritional information says 2 pancakes is a serving containing 150 calories. For breakfast, I prepared half a recipe, but made smaller sized pancakes, so ended up preparing 8 pancakes. I ate 4 of them. How many calories did I consume?
Answer:
225 calories
Step-by-step explanation:
1 recipe makes
12 standard sized pancakes
2 pancakes are 1/6 of the recipe
1/6 of the recipe has 150 calories
6 × 150 calories = 900 calories
The full recipe of 12 pancakes has 900 calories
1/2 recipe was made
1/2 recipe has 1/2 × 900 calories = 450 calories
1/2 recipe made 8 pancakes
4 pancakes are half of the half recipe or 1/4 recipe
1/4 × 900 calories = 225 calories
