The temperature of a cup of coffee t minutes after it has been poured is described by the function C(t) = 20 + 60(0.95)^t . a. H
scoundrel [369]
The temperature of coffee 10 minutes after it was poured (120 F) will help in solving the constant “a”. 
<span>120 = 120(2 ^ 10a) + 60 </span>
<span>2 ^ -1 = 2 ^ 10a </span>
<span>a = -1/10 </span>
<span>The temperature of coffee 30 minutes after it was poured is: </span>
<span>F = 120 ( 2 ^ -30/10) + 60 </span>
<span>F = 120 * 1/ 8 + 60 </span>
<span>F = 15 + 60 </span>
<span>F = 75</span>

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).
