The value of the function f(x)=3(4-x) when x=7 is -9. This is calculated by substituting x=7 into the function and simplifying.
To find the value of the function f(x)=3(4-x) when x=7, you should insert x's value into the equation. Therefore, the function takes the form: f(7)=3(4-7). Then you simplify it to: f(7)=3(-3) and further simplification gives: f(7)=-9.

Answer:To solve this problem, we need to standardize the values of 55 and 63 to z-scores and then use the standard normal distribution table to find the area between those two z-scores.
The z-score for a value of 55 is:
z = (55 - 62) / 4 = -1.75
The z-score for a value of 63 is:
z = (63 - 62) / 4 = 0.25
Using a standard normal distribution table, we can find that the area to the left of z = -1.75 is 0.0401 and the area to the left of z = 0.25 is 0.5987. Therefore, the area between z = -1.75 and z = 0.25 is:
0.5987 - 0.0401 = 0.5586
To convert this area back to a percentage, we multiply by 100:
0.5586 * 100 ≈ 55.9%
Therefore, the answer is A. 55.9%.
