Step-by-step explanation:
Given data:
Range of jumps = 71 to 84 inches
Mean of jumps = 76 inches
standard deviation = 3.5
To calculate the percent of jumpers in the group jumping below 79.5 inches
Let us calculate the number of standard deviation in 79.5 inches
= 79.5/3.5
= 22.71 times

Answer: 76 </h3>
=======================================================
Explanation:
Replace x with 4 and y with 5.
Then use the order of operations (PEMDAS) to simplify until you get a single number.
Something like 9x means "9 times x", and a similar situation happens with the 8y term as well.
---------
Here's what the steps look like:
9x + 8y
9*4 + 8*5
36 + 40
76
Therefore, 9x+8y = 76 when x = 4 and y = 5.
The point (4,5) is located on the line 9x+8y = 76
