Arr arrange the 22  scores in ascending order. The median will be the 'middle'  2 scores which is the mean of the 11th and 12th score.

The middle 2  scores are 174 and 175 so the median = 174.50.

BIG IDEAS MATH
sveticcg [70]

Answer:

The required expression is \frac{y}{4}-3.

The value of the expression when y=20 is 2.

Step-by-step explanation:

Consider the provided phase.

3 less than the quotient of a number y and 4

The quotient of a number y and 4 can be written as: \frac{y}{4}

Now 3 less than the quotient of a number y and 4  can be written as:

\frac{y}{4}-3

Hence, the required expression is \frac{y}{4}-3.

Now evaluate when y=20.

Substitute y=20 in above expression.

\frac{20}{4}-3

5-3

2

Hence, the value of the expression when y=20 is 2.

How to solve -6&lt;-2x&lt;14
algol13
Hey there! :) 

-6 < -2x < 14

We're trying to solve for x. To solve for x, we must isolate x.

So, let's divide everything by -2!

-6 ÷ -2 < -2x ÷ -2 < 14 ÷ -2

**Remember : when dividing by a negative number, you MUST switch the sign! So, if the sign is ">" then we switch it to "<" and the other way around **

3 > x > -7

So, our answer is : → 3 > x > -7

~Hope I helped!~
