EXPERT HELP: EXPLAIN THE ANSWER
Answer:
A
Step-by-step explanation:
A. The average height is greater since it has a higher mean, it also vareis less
Why the others wouldn't make sense?
B. While the average height is greater, Vareity A has a smaller MAD so that means it is more consistent with it experiment results.C is wrong, the minimum height of Vareity A is 16 , while Vareity B maximum height is 18. This means Maximum B was taller than Vareity A at one point.D is wrong, Vareity A max height is 20 while Vareity b max height is 18. 20>18 so that is falseI need help with this.

What is the Width, explain how you got your answer (8 points btw)
Answer:
Based off of my calculations, I got 126
Step-by-step explanation:
The formula for area would be: A = L * W
So, when finding the width (W), you would need to divide the area (A) by the length (L).
Equation: W = A / L
Now you know the equation, all you need to do is plug in the numbers:
[84 divided by 2/3]
W = 84 / 2/3
After solving this, you would get: 126
So, W = 126.
To check if we got the correct answer, we could just multiply the length times the width:
126 * 2/3
Since this equation gives us 84 as the answer, 126 is the correct width.

Which expression is equivalent to the phrase shown below? 7
the quotient of the sum of and , and twice the cube of A
ANSWER THESE TWO QUESTIONS FOR ME:
1. If the surface area of a cube is 390 cm², then which best describes the length of the side of the cube?
A. less than 7 cm
B. between 7 cm and 8 cm
C. between 8 cm and 9 cm
D. greater than 9 cm
2. The net below shows equilateral triangles. What is the total surface area of the triangular pyramid in square feet?
Answer:
65^2
Step-by-step explanation:
if you woulndt mind giving me brainliest im trying to rank up, only if u dont mind.
#1:
Between 8 cm and 9 cm
Work:
SA = 6s^2
390 = 6 s^2
390/6 = 6s^2 /6
65 = s^2
sqrt(65) = s
s = 8.06
#2:
The total surface area of the triangular pyramid is 107 * square feet.
What is a triangular pyramid?
Take a triangle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first triangle and when they're taken together, they form a closed object, called as a triangular pyramid.
We are given that;
The length of median from outer triangle to side of the inner triangle is 8 ft
Side of inner equilateral triangle is 12 ft
Now,
First, we can find the height of the outer equilateral triangle using the Pythagorean theorem:
a is half the length of the side of the inner triangle (6 ft), m is the length of the median (8 ft), and b is the length of the side of the outer triangle (unknown).
a^2 + (m/2)^2 = b^2
b^2 = 6^2 + 8^2/4
b^2 = 36 + 4
b^2 = 40
b = sqrt(40)
b = 2 * sqrt(10)
So the height of the outer triangle is:
h = b * sqrt(3)/2
h = sqrt(30)
Now we can find the area of each equilateral triangle using the formula:
A = (sqrt(3)/4) * s^2
For the inner triangle:
A_inner = (sqrt(3)/4) * 12^2
A_inner = 36 * sqrt(3)
For the outer triangle:
Now we can find the area of the base, which is just the area of the inner equilateral triangle:
A_base = A_inner
A_base = 36 *
Finally, we can find the surface area of the triangular pyramid by adding the areas of the four triangles and the base:
SA = A_inner + 3 * A_outer + A_base
A student is comparing two jobs.
Job 1
Job 1 pays an annual base salary of $34,000 with a 3% increase in salary per year.
Job2
y=35,00(1.02)^x
x: time in years
y: total annual salary
Which statement is true?
Both annual salary and the percent yearly raise are higher at Job 1 than 2.
Both the annual base salary and the percent yearly raise are higher at Job 2 than 1.
While the annual base salary of Job 1 is higher than 2, the percent yearly raise is higher and Job 2 than 1.
While the annual base salary at Job 2 is higher than 1, the percent yearly raise is higher at Job 1 than 2.
Answer:
While the annual base salary at Job 2 is higher than 1, the percent yearly raise is higher at Job 1 than 2.
This seems the most correct to me; your answer is D.
