1. You are trying to isolate "F" in the equation
Multiply 9/5 on both sides
Add 32 on both sides
THIS IS WRONG
2. You are trying to isolate "y" in the equation
Multiply 3 on both sides
3m = x + y + z Subtract x and z on both sides
3m - x - z = y
THIS IS CORRECT
3. Isolate "r"
Multiply (r - 1) on both sides
s(r - 1) = r Distribute s into (r - 1)
sr - s = r Subtract sr on both sides
-s = r - sr Factor out r from (r - sr)
-s = r(1 - s) Divide (1 - s) on both sides
THIS IS WRONG
4. Isolate "b"
Multiply 2 on both sides
2A = a + b Subtract a on both sides
2A - a = b
THIS IS CORRECT
5. Isolate "y"
Multiply 2 on both sides
2m = x + y Subtract x on both sides
2m - x = y
THIS IS WRONG
The 2nd and 4th one is right
Answer:
5.8 years
Step-by-step explanation:
The sampling distribution of the sample means has a mean that is equal to mean of the population from which the sample has been drawn.
study of elementary school students reports that the mean age at which children begin reading is 5.8 years with a standard deviation of 0.7 years.
This means the population mean is
and the population standard deviation is
If a sampling distribution is created using samples of the ages at which 61 children begin reading, the mean of the sampling distribution of the sample mean will be
