A new shirt costs $14.99. If the shirt in sale for 1/5 off its price, about much would you save. SOLUTION PLS

Tasya [4]

Answer:

As per the given condition:

A new shirt costs $14.99.

If the shirt has a sale for $\frac{1}{5}$ off its price.

Now, we find how much you save on this shirt:

First find the $\frac{1}{5}$ of $14.99

i.e,

$\frac{1}{5} \times \$14.99 = \frac{\$14.99}{5} =\$ 2.998$

⇒ you have the discounted value is $ 3 .

You pay for the shirt is: $14.99 -$ 2.998 = $11.992

Therefore, you would save $2.998 or $ 3 in buying your new shirt.

Data were collected from a typing class with 45 students. The class had an average of 56 words per minute (WPM) with a standard

STALIN [3.7K]

Answer:

Standard deviation gets smaller

Step-by-step explanation:

No. of students = 45

The class had an average of 56 words per minute (WPM) with a standard deviation of 7 WPM.

$Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}\\56=\frac{Sum}{45}\\56 \times 45=Sum\\2520=Sum$

The teacher realized that the data from one student who typed 55 WPM was not entered.

So, new sum = 2520+55

New sum =2575

So, new mean = $\frac{2575}{45}$

New mean =57.22

Standard deviation is the measure of distance between observation and mean

So, if number gets closer to mean , Standard deviation gets smaller . if the numbers get bigger , Standard deviation gets bigger.

Since 55 is closer to 57.22

So, Standard deviation gets smaller
