The z-score will be given by:
z=(x-μ)/σ
given that:
x=94
μ=mean=84.5
σ=standard deviation=4.4
thus
z=(94-84.5)/4.4
z=2.1591

select the inequality that represents the relationship desribed below the sum of three times a number and seven is greater than
solong [7]

Answer:

There are many combinations based on the number you chose to subtract from both sides.

Step-by-step explanation:

Let the number be x.

According to the question,

3 x+7 > 4 x

We get, 3 x+1=4 x-6, after subtracting 6 from both sides.

3 x+1=4 x-6

4 x- 3 x=6+1

x=7

You will get the same answer if you subtract 3 x or 7 or any other number from both sides.

Thank you!
