What is slope?A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.
Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula.
Since the pizza was heated at a constant rate, we can model the experiment as a line, where the slope represents how fast the pizza was heated.
The slope is given as:
m = (y2 - y1)/(x2 - x1)
Let
(x1,y1) = (6, 40)
(x2,y2) = (8, 55)
m = (55 - 40) / ( 8 - 6 )
m = 7.5 degrees per minute.
The pizza heats up an average of 7.50 degrees per minute
To reach a temperature of 100 degrees the pizza would take:
(100)(7.50) = 750 minutes.

A candy bar box is in the shape of a triangular prism. The volume of the box is 1,200 cubic centimeters.
See picture
Part A: What is the height of the base? Show your work. (5 points)
Part B: What is the approximate amount of cardboard used to make the candy
box? Explain how you got your answer. (5 points)
Assuming a thickness of 1 millimeter for the cardboard, the amount of cardboard utilized to build the candy box is roughly 240 cubic centimeters.
What is volume?Volume is the quantity of space in a 3D object in arithmetic. A fish tank, for example, is 3 feet long, 1 foot wide, and 2 feet tall. To calculate the volume, multiply the length by the breadth by the height, which is 3x1x2, which is six. As a result, the fish tank has a volume of 6 cubic feet.
Here,
Part A: To find the height of the base, we need to use the formula for the volume of a triangular prism:
V = Bh/2,
where B is the area of the base and h is the height.
We can assume the base of the triangular prism is an equilateral triangle with side length s. The area of an equilateral triangle can be found using the formula:
B = (s² * √(3))/4
We can use this formula to find the side length of the triangle:
s = √((4B)/(√(3)))
Substituting the known values, we have:
1200 = (s² * √(3))/2 * h
solving for h:
h = 1200 * 2 / (s² * √(3))
Substituting the value for s:
h = 1200 * 2 / ((√((4B)/(√(3)))² * √(3))
h = 1200 * 2 / (((4B)/(√(3))) * √(3))
h = 1200 * 2 / (4B)
h = 300 / B
We can find the value of B using the formula:
B = (s² * √(3))/4
Substituting the value for s:
B = (√((4B)/(√(3)))² * √(3))/4
B = (4B)/(3 * √(3))
B = 4B / (√(9))
B = 4B / 3
Solving for B:
B = 300 / h
So, the height of the base is approximately 30 cm.
Part B: To find the amount of cardboard used to make the candy box, we need to find the surface area of the triangular prism and multiply it by the thickness of the cardboard.
The surface area of a triangular prism can be found using the formula:
A = B + Bs + Bh
Where B is the area of the base, Bs is the area of the side of the triangular prism and Bh is the area of the top and bottom of the triangular prism.
We know that B = (s² * √(3))/4 and Bh = B, so
A = B + Bs + Bh = B + 2Bh = 2B + 2Bs
The surface area of the triangular prism is approximately 240 square centimeters.
Assuming the cardboard has a thickness of 1 millimeter, the amount of cardboard used to make the candy box is approximately 240 cubic centimeters.

(a) E(Y) = 37.5, Var(Y) = 50
(b) E(Y) = 37.5, Var(Y) = 4.5
(c) E(Y) = 37.5, Var(Y) = 15
(d) E(Y) = 37.5, Var(Y) = 30
(e) E(Y) = 125, Var(Y) = 4.5
The correct option is (b) as the expected value and variance of daily revenue are 37.5 and 4.5 respectively.
What is meant by variance?
Consider the expected value to be the average value. The expected value of X when it is a discrete random variable is the exact mean of the relevant data.
The difference between the actual numbers and the average should be viewed as the variance. A greater range of values is indicated by a higher variance. A spread of measure for a random variable distribution that quantifies how much a random variable's values deviate from its expected value is called variance. Frequently, V(X) is used to represent the variance of random variable X.
Given,
Cost of soft drink c = $0.30
Expected value of the number of cans sold per day E(X) = 125
Variance of number of cans sold per day V(X) = 50
So,
Expected value of daily revenue E(Y) = c * E(X) = 0.3 * 125 = 37.5
Variance of daily revenue V(Y) = c² * V(X) = 0.3² * 50 = 4.5
Therefore the expected value and variance of daily revenue are 37.5 and 4.5 respectively. The correct option is (b).

the heights of a group of students, in centimeters, are 158, 162, 172,.157, 161.com. A) caculate the mean heaight . B) another student joins the group. his height is 169cm. calculate the new mean height?
Step-by-step explanation:
So basically To find the mean you have to add all the numbers and divide by how many numbers you have, but to do that you have to make sure the numbers are lined up correctly so
157,158,161,162,172 ( Correct Order ) Smallest to biggest now add these up
157 + 158 + 161 + 162 + 172 = 810 / 5 = 162
The mean height is 162 cm
The new mean height
Again we're going to do the same thing
157 + 158 + 161 + 162 + 169 + 172 = 979/6 = 163.16666 = 163 cm
Hence the first mean height is 162 cm and the new mean height is 162 cm
What is the sum of the first 45 terms of an arithmetic sequence if the sum of its 18 th and 28 th term is 36?
The sum of 45 terms of the arithmetic progression whose sum of 18 th and 28 th terms is 36 is given by 810.
Let the first term of the arithmetic progression be A and the common difference for the same be D.
So 18th term of the progression is = A + (18 - 1) D = A + 17D
28th term of the progression is = A + (28 - 1) D = A + 27D
Given that the sum of the 18th and 18th terms of the progression is 36.
So, A + 17D + A + 27D = 36
2A + 44D = 26
So now the sum of 45 terms of the arithmetic progression is given by,
= 45/2 [2A + (45 - 1)D]
= 45/2 [2A + 44D]
= (45/2) * 36
= 45 * 18
= 810
Hence the sum of 45 terms of the arithmetic progression whose sum of 18 th and 28 th terms is 36 is given by 810.
