Answer: a) 27.5, b) 5.33.
Step-by-step explanation:
Since we have given that
and n = 180
We need to calculate the sample mean and sample standard deviation.
So, the mean of the distribution of sample means is
The standard deviation of the distribution of sample means is
Hence, a) 27.5, b) 5.33.
Answer:
A+B=3
BC+B=18
BC+A=6 ;;
Step-by-step explanation:
sorrry i dont know that im sorry
let "a number" = x
a number is divided by 3 => x/3
14 is added to the quotient => (x/3) + 14
The result is 33 => " = 33"
Solve for x
(x/3) + 14 = 33
Isolate the x. Note the equal sign. What you do to one side you do the other.
Subtract 14 from both sides
(x/3) + 14 (-14) = 33 (-14)
x/3 = 19
Isolate the x. Multiply 3 to both sides
x/3(3) = 19(3)
x = 19(3)
x = 57
57 is your original number
