The value of y = 4
When two lines are parallel and is cut by a transversal, the alternate angles are equal
y² = 8y - 16
y² - 8y + 16 = 0
y² - 4y - 4y + 16 = 0
y(y - 4) -4(y - 4) = 0
(y - 4)(y - 4) = 0
y - 4 = 0
y = 4
Therefore, the value of y = 4

The critical value is
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 8 - 1 = 7
80% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 7 degrees of freedom(y-axis) and a confidence level of . So we have T = 1.415.
The critical value is
Answer:
The answer is 19.25
Step-by-step explanation:
<u>Key skills needed: Fraction operations, decimal conversion</u>
1) We are given the hint to use 9 as "b", and we get:
--->
Let's do
--> is the same as ÷
16 divide by 8 is 2.
2) This means that it would be ---> which is simply 2 times 9.
2 times 9 = 9 + 9 = 18
3) With that result, it would be --->
Now, do (10 divided by 8) ---> Get 1.25
4) 18 + 1.25 = 19.25, so --> is the answer
