Answer:

90

Step-by-step explanation:

The magazines are sold at a discount. Discount reduces the price of the good

If the magazines are sold at 20%, the magazine's price would be 80% (100% - 20%) of the original price

let a represent price of the magazine before the discount

This equation represents price of the magazine after the discount

0.8 x a = $72

Divide both sides by 0.8 and find a

a = $90

Given u = (2, -8) and v = (8, -2), what is u times v?
jolli1 [7]

Answer:

u\cdot v=32

Step-by-step explanation:

Assuming u and v are vectors, their dot product is u\cdot v where u_1v_1 + u_2v_2:

u\cdot v=u_1v_1+u_2v_2=(2)(8)+(-8)(-2)=16+16=32

Therefore, u\cdot v=32

Below is a data set containing six observations in ascending order
son4ous [18]
<h3>Answer:  91</h3>

========================================================

Explanation:

The observations are in ascending order, which means the set is sorted from smallest to largest.

The X is at the right-most endpoint, so X is the largest value (aka the max).

The min is 33, so,

max - min = range

X - 33 = 58

X = 58+33

X = 91 is the max
