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 all possible combinations: A,B,(A or D), (A or C), A

The bike store marks up the wholesale cost of all of the bikes they sell by 30%.
Andre wants to buy a bike that has a price tag of $125. What was the wholesale cost of this bike?
If the bike is discounted by 20%, how much will Andre pay (before tax)?
(Please make sure to add a good explanation on how you found the answer because I have seen some where I didn't understand where a certain number came from.)
Answer:
Wholesale: $37.50
Discount: $7.50
Explanation:
*The wholesale cost of all the bikes they sell is 30%
*Andre wants to buy a bike for $125
*If the bike is discounted by 20%
[tex]\frac{30}{100}[/tex] = [tex]\frac{x}{125}[/tex] (solve for x)
100x = 125 x 30
100x = 3750
(x = $37.50 for the wholesale)
For the discount, we need to find 20% of 37.5
An easier way we can do is to find 10% and to multiply by 2. So, move the decimal to the left of 37.5 and we get 3.75 and multiply by 2
3.75 x 2 = 7.5 ($7.50 the discount)
*
Answer:
$37.50
$7.50

Find the value of x please help dont know math at all
Answer:
D. 4
Step-by-step explanation:
A straight line equals 180 degrees if there's already 140 degrees then you need 40 more to make the line true so 10 times 4 is 40 to make 140 + 40 = 180 true
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
