Answer:

a.) 26< a <u>28 </u>

b.) 4

Step-by-step explanation:

a.) After looking at the age in years collum you can notice that all of ages have a difference of 2. With this you can infer that the missing number is 28.

b.) To find the mean add up all the numbers in the frequency column.

3+2+7+8+0=20

Divide that by the amount of numbers. There are 5 numbers so 20/5=4.

Hope this helps!

“3 less than the quotient of y and 4”

Bingel [31]

Answer:

Expression:

$\dfrac{y}{4}-3$

Value where y = 20

Step-by-step explanation:

Let's take a look at the sentence:

3 less than the quotient of y and 4

3 less indicates that you will subtract

- 3

Quotient means the result of division.

$\dfrac{y}{4}$

So if we combine the two, it says 3 less than the quotient so we subtract 3 from the quotient:

$\dfrac{y}{4}-3$

So if y = 20, we just substitute the y with 20

$\dfrac{y}{4}-3$

$\dfrac{20}{4}-3$

$5-3=2$
