You can utilize the Pythagorean theorem expressed as a^2 + b^2 = c^2... if b is unknown, you can rearrange the formula. Hence, c^2 - a^2 = b^2. Squaring 47 gives 2209 and squaring 13 yields 169... Subtracting gives you 2209-169, which results in 2040. Taking the square root of that yields approximately 45.166359, which can be rounded to 45 or as 45.167 when expressed to two decimal places. I hope this helps!:)
Response:
The average of the 10 sales figures for store A is $40,000.
Detailed explanation:
Provided;
yˆ= −3,000 + 1.2x...................... (1)
Where;
x = daily sales amounts at store A or the average of the 10 sales amounts for store A =?
yˆ = daily sales amounts at store B or the average of the 10 sales amounts for store B = $45,000
Substituting y = 45,000 into equation (1) and solving for x, yields:
45,000 = −3,000 + 1.2x
45,000 + 3,000 = 1.2x
48,000 = 1.2x
x = 48,000 / 1.2
x = 40,000
Consequently, the mean of the 10 sales figures for store A is $40,000.

Answer:
43.2in
Step-by-step explanation:
If the two individuals maintain proportionality, then with the waist measurement of one person known, we can determine the other's waist size through the established ratio.
36in*(1*20%) = 36in*1.2 = 43.2in
