Answer:

The lengths of the diagonals is 22.

Step-by-step explanation: Since the shape is a rectangle, the diagonals are congruent, we can form the equation 3x+7=5x-3.

Solve for x; 2x=10-->x=5.

Plug 5 into one of the equations. 3(5)+7=22. 5(5)-3=22

Hope this helps!

If it is a 270 degree rotation cw, then it changes from (x,y) to (y,-x).

(-3,4) ---> (4,3)

A clothing store uses comment cards to get feedback from its customers about newly added items. It recently introduced plus size

irga5000 [103]

Answer:

The percentage of customer would less likely to purchase next item is 26.2%

So, The nearest option will be (e).

Step-by-step explanation:

Given that,

The table of information is

Response = Very satisfied, Satisfied, less than fully satisfied and not satisfied

Frequency = 15, 30, 12 and 4

We need to calculate the total frequency

Using given frequency

$Total\ frequency = 15+30+12+4$

$Tota\ frequency = 61$

We need to calculate the total number of customers less or not fully satisfied

Using given data

$x = 12+4$

$x=16$

Where, x = total number

We need to calculate the percentage of customer would less likely to purchase next item

Using formula for percentage

$percentage\ of\ customer=\dfrac{total\ number\ of\ customer}{total\ frequency}\times100$

Put the value into the formula

$percentage\ of\ customer=\dfrac{16}{61}\times100$

$percentage\ of\ customer=26.2\%$

Hence, The percentage of customer would less likely to purchase next item is 26.2%

So, The nearest option will be (e).
