Answer:a is 52    b is 65
Step-by-step explanation:
a:Write 65% as 65100.
65100 of 80 = 65100 × 80.
Therefore, the answer is 52. If you are using a calculator, simply enter 65÷100×80 which will give you 52 as the answer.
b: it is 65 because it is the same question but in reverse which still gives you the same answer.

Answer:
a) 0.3571
b) The p-value is 0.362007.
Step-by-step explanation:
We are given the following in the question: 
Population mean, μ = 1.35
Sample mean,  = 1.4
 = 1.4
Sample size, n = 26
Alpha, α = 0.01
Sample standard deviation, s = 0.7
First, we design the null and the alternate hypothesis
 
 
We use One-tailed t test to perform this hypothesis.
a) Formula:
 
 
Putting all the values, we have
  
 
b) The p-value at t-statistic 0.3571 and degree of freedom 25 is 0.362007.

Answer:
Its 7.333333333333333333  (3 forever)
First you isolate y onto one side of the equation
y/9= 44/54  -->  y = 9 x 44/54
Multiply the right side of the equation
9 x 44/54 = 396/54
Now divide to get the whole answer
396/54 = 7.3333333333 (3 forever)
y = 7.333333
