y = 12
Step-by-step explanation:
36 - 24 = 12.
24 calories were burned in 100 minutes. 36 calories were burned in 150 minutes. That means that in 50 minutes (150 - 100) 12 calories were burned.
Graph the line that passes through the points (7, 0) and (-2, 9) and determine the equation of the line.
Answer:
y = -1x + 7
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - 0 / -2 - 7
9 / -9
= -1
y = -1x + b
0 = -1(7) + b
0 = -7 + b
7 = b
A shop window is 6 meters long and has an area of 18m².What is the height of the window
Answer:
3 meters
Step-by-step explanation:
Assuming the window is rectangular
A = l*h
18 = 6*h
Divide each side by 6
18/6 = 6h/6
3 = h
Jack and Jill both ordered pizzas from Wayne's Pizza for their parties. Jack paid $58.50 for 3 pepperoni pizzas and 2 plain pizzas. Jill paid $67 for two pepperoni pizzas and 4 plain pizzas. How much does Wayne's Pizza charge for a plain and for a pepperoni pizzas?
Answer:
A plain pizza is $10.50 and a pepperoni pizza is $12.50
Step-by-step explanation:
Create a system of equations where x is the price of a pepperoni pizza and y is the price of a plain pizza:
3x + 2y = 58.5
2x + 4y = 67
Solve by elimination by multiplying the top equation by -2:
-6x - 4y = -117
2x + 4y = 67
Add these together and solve for x:
-4x = -50
x = 12.5
So, a pepperoni pizza is $12.50. Plug in 12.5 as x into one of the equations, and solve for y:
2x + 4y = 67
2(12.5) + 4y = 67
25 + 4y = 67
4y = 42
y = 10.5
So, a plain pizza is $10.50.
A plain pizza is $10.50 and a pepperoni pizza is $12.50
A quadratic function has x-intercepts 2 and 6 and its vertex is (4, 8). What is the corresponding quadratic expression? A. 2x2 − 16x + 24 B. -2x2 + 16x – 24 C. -2x2 - 16x + 24 D. -x2 − 16x + 12 E. -x2 − 16x – 24
Given:
A quadratic function has x-intercepts 2 and 6 and its vertex is (4, 8).
To find:
The corresponding quadratic expression.
Solution:
If graph of a function intersect the x-axis at c, then (x-c) is a factor of the function.
A quadratic function has x-intercepts 2 and 6. It means (x-2) and (x-6) are two factors of the required quadratic function.
The function is defined as:
[tex]P(x)=a(x-2)(x-6)[/tex] ...(i)
Where, a is a constant.
The vertex of the quadratic function is (4,8). It means the point (4,8) will satisfy the function.
Substituting x=4 and P(x)=8 in (i).
[tex]8=a(4-2)(4-6)[/tex]
[tex]8=a(2)(-2)[/tex]
[tex]8=-4a[/tex]
Divide both sides by -4.
[tex]\dfrac{8}{-4}=a[/tex]
[tex]-2=a[/tex]
Putting [tex]a=-2[/tex] in (i), we get
[tex]P(x)=-2(x-2)(x-6)[/tex]
[tex]P(x)=-2(x^2-6x-2x+12)[/tex]
[tex]P(x)=-2(x^2-8x+12)[/tex]
[tex]P(x)=-2x^2+16x-24[/tex]
Therefore, the correct option is B.

A man stands on top of a mountain, at the bottom of the mountain the velocity of the man is 12m/s, how tall is the mountain
Answer:
the height of the mountain is 7.35 m
Step-by-step explanation:
Given;
final velocity of the man, v = 12 m/s
initial velocity of the man, u = 0
The height of the mountain is calculated as;
v² = u² + 2gh
v² = 0 + 2gh
v² = 2gh
h = v²/2g
h = (12)² / (2 x 9.8)
h = 7.35 m
Therefore, the height of the mountain is 7.35 m

============================================================
Explanation:
Use the slope formula to find the slope of the given line through those two points (-3, 4) and (5, 1)
m = (y2-y1)/(x2-x1)
m = (1 - 4)/(5 - (-3) )
m = (1-4)/(5+3)
m = -3/8
The line shown has a slope of -3/8
----------
We do two things from here:
flip the fractionflip the signThat will have -3/8 turn into +8/3 or simply 8/3 which is the perpendicular slope. That's why the answer is choice A.
Multiplying the original slope -3/8 with the perpendicular slope 8/3 will lead to -1. This is true of any perpendicular pair of lines, as long as neither line is vertical.

CONTEST Each ple entered into the annual pie baking contest has been scored out of 10, as shown in the table.
Answer:
Of your choices, 87.5
Step-by-step explanation:
There may be a formula for figuring this out, but here's what I know how to do to solve this:
First we'll organize the data in ascending order:
3.9, 4.5, 5.7, 6.2, 7.4, 8.1, 8.4, 9.2
The median is (6.2 + 7.4)/2 = 6.8
The first quartile is (4.5 + 5.7)/2 = 5.1
The third quartile is (8.1 + 8.4)/2 = 8.25
So the 75th percentile is 8.25
Since 9.2 is higher than that, I'd choose 87.5
Mildred's pie scored at the 87.5 percentile.
What is a percentile?'A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall.'
According to the given problem,
Organizing the data in ascending order:
3.9 < 4.5 < 5.7 < 6.2 < 7.4 < 8.1 < 8.4 < 9.2
Median of the given data = [tex]\frac{6.2+7.4}{2}[/tex]
= 6.8
First quartile = (4.5 + 5.7)/2
= 5.1
Third quartile = (8.1 + 8.4)/2
= 8.25
The third quartile is the 75th percentile,
⇒ 75th percentile = 8.25
Since, 9.2 > 8.25 , Mildred's pie scored at 87.5 percentile.
Hence, we can conclude, Mildred's pie scored at the 87.5 percentile.

Consider the probability model that allows you to determine probability that there will be X number of successes out of n trials; when the outcomes from each trial (each defined as either a success or a failure), are independent, and subject to the same probability of success from one trial to the next. How will the coefficient of variation for this model change
Answer:
The probability of number of success = C (n,k)p^kq^(n-k)
Step-by-step explanation:
This is the case of Bernoulli's experiment in which there are n independent trials with X number of success
The probability of number of success = C (n,k)p^kq^(n-k)
Where k = 0,1,2,3...n

Find the aspect ratio of a computer screen that measures 12 inches by 16 inches.
Answer:
3:4
Step-by-step explanation:
That ratio would be 12:16, or 3:4.
The aspect ratio of a computer screen will be 4: 3.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
The computer screen measures 12 inches by 16 inches.
Then the aspect ratio will be given by the number 16 inches divided by 12 inches.
We know that the aspect ratio will be greater than 1. Then the aspect ratio will be
Aspect ratio = 16 / 9
Aspect ratio = 4/3
Aspect ratio = 4: 3
The aspect ratio of a computer screen will be 4: 3.

what is the mode of the data set 8, 8, 9, 10, 11
Answer:
the 'mode' of 8, 8, 9, 10, 11 is 8
Step-by-step explanation:
The 'mode' of a data set is the value that shows up most. Note how 8 shows up twice here, whereas 9, 10 and 11 show up only once each.
Thus, the 'mode' of 8, 8, 9, 10, 11 is 8.

Answer:
82.8
Step-by-step explanation:
LAW OF COSINES

What is the area of the polygon enter your answer in the box
43.5 units2
45.5 units2
56.5 units2
49.5 units2
Answer:
Option (1)
Step-by-step explanation:
Area of the polygon = Area of CDE + Area of EFG + Area of ABCF
Area of triangle CDE = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(3)(2)[/tex]
= 3 units²
Area of ΔCDE = [tex]\frac{1}{2}(5)(1)[/tex]
= 2.5 units²
Area of trapezoid ABCF = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
= [tex]\frac{1}{2}(8+11)(4)[/tex]
= 38 units²
Area of the given polygon = 3 + 2.5 + 38
= 43.5 units²
Therefore, Option (1) will be the correct option.
