Step-by-step explanation:
Answer:
6(2c - 1)
Step-by-step explanation:
Since this is a binomial that has no special form, visibly, we can factor it by its GCF.
The GCF of this binomial is 6.
Factoring this out of the expression, we get:
12c - 6
= 6(2c - 1)
Answer:
a. Standard error of mean
Step-by-step explanation:
The standard error of mean is computed by dividing the standard deviation to the square root of sample size. It can be represented as
The standard deviation of the sampling distribution is known as the standard error of mean because it measures the accuracy of sample mean as compared to population mean
Answer:
Im pretty sure its A. 83%
Step-by-step explanation:
Answer:
Mary-15
Joan-9
Step-by-step explanation:
1) create an equation with the information given:
x•(x+6)=135
2) using this create a quadratic equation by distributing and getting all the terms to one side:
y=x²+6x-135
3) finally use the quadratic formula, ((-b)±√(b²-(4•a•c)))/(2•a)
4) using this you will find the value for Joan's age. Add six to Joan's age to find Mary's
5) You can check your answer by multiplying them to see if they equal 135.
