Answer:
2 oldies and 6 new releases
Step-by-step explanation:
let x equal number of oldies
let y equal number of new releases
2x + 4y = 28
x + y = 8
x = 8 - y
2(8 - y) + 4y = 28
16 - 2y + 4y = 28
2y = 28 - 16
2y = 12
y = 12/2
y = 6
x = 8 - y
x = 8 - 6
x = 2
Answer:
B (2,8)
Step-by-step explanation:
using the formula:
y = mx +b
Using the given slope and coordinate points we get:
-1 = -3(2) + b
-1 = -6 + b
add 6 to each side
5 = b
y = -3x + 5
which is the same as:
3x + y = 5 ...answer choice a

There are 14 values above. The mean of these 14 numbers is calculated by dividing their sum by 14 which will give us an answer of 117.07 or ~117. The smallest of these values is 69 which is 48 units to the left of the average. The largest value is 189 which is 72 units to the right of the average. Therefore, in this distribution, the values are skewed to the right.
