Answer is 5 hope i helped
Y=2-3(x-7)
You just add +2 to each side and the positive and negative cancel out and it switches it over
Answer: the value of population standard deviation is 3.87
Step-by-step explanation:
From the information given,
Number of sample, n = 8
For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean ± z ×standard deviation/√n
Since confidence interval = 2.694,
It becomes
2.694 = 1.96 × standard deviation/√8
Dividing both sides of the equation by 1.96, it becomes
1.37 = standard deviation/√8
Standard deviation = 1.37 × √8
Standard deviation = 3.87
I hope you understand my work goodluck :)

Answer:
Find a number that divides equally in both the numerator and denominator then divide the numerator and denominator by the number you just found an
Step-by-step explanation:
1) Find a number that divides equally in both the numerator and denominator
2) Then divide the numerator and denominator by the number you just found
3) Keep on doing this until you can't divide the numerator and denominator exactly with the number you found
