The mean score on a calculus exam was 40 and the standardize deviation was five. The teacher decided to double everyone score and then add seven points. What are the values of the mean and standard deviation of the distribution of transform exam scores

The mean will double and add 7, the SD will double

Step-by-step explanation:

If the old mean is x, the new mean will be 2x+7, and since the SD is based on x, the SD for after the curve will based on 2x, so it will also double.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

they aren't great and cause destruction, idk man
