Answer:
x = 3z(y - 2)
Step-by-step explanation:
Given
= y - 2 ( multiply both sides by 3z to clear the fraction )
x = 3z(y - 2)
Answer:
x
=5, y
=0
Step-by-step explanation:
Okay, so Sang is standing 20 yards away from one corner, and Jazmin is standing 99 yards away from the same corner. If this is a rectangle (I like visuals, so I'll use them to explain), then:
99ft
A ------------------------- B
| |
20 ft | |
| |
C -------------------------- D
The question is asking you to solve for the diagonal line between points C and B. If you imagine a line there, you actually have the rectangle split into two triangles. So if you have triangle ABC, side CB would be the longest line, or the hypotenuse. That means you can use the Pythagorean Theorem to solve the problem.
A^2 + B^2 = C^2
99^2 + 20^2 = C^2
9,801 + 400 = C^2
10,201 = C^2
Now you solve for the square root of 10,201 to get C.
sqr (10,201) = C
C = 101 yards
Answer:
972π in³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = 
πr³ ← r is the radius
Here r = 9, thus
V = π × 9³ = π × 729 ( divide 3 and 729 by 3 )
= 4π × 243
= 972π in³
Answer: Cluster sampling
Step-by-step explanation:
A cluster sampling is a kind of random sampling technique in which the researcher splits the whole population into distinct sets known as clusters.
After that, he choose a random sample of clusters from the population and do analysis on it.
In the given situation, the objective of survey : "To determine customer opinion of their pricing:".
He first divides the number of check out lines according to weeks and randomly selects 140 check out lines during a certain week and surveys all customers in the check out lines. .
(Here , check out lines = clusters )
Therefore , the type of sampling is used = Cluster sampling
