Answer:
Step-by-step explanation:
T is at (1,2)
where x = 1 and y = 2
so if it's reflected over the x axis then it moves down wards. to (1, -2)
Answer:
The 90% confidence interval of the population proportion is (0.43, 0.56).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population proportion <em>p</em> is:

The information provided is:
<em>X</em> = 74
<em>n</em> = 150
Confidence level = 90%
Compute the value of sample proportion as follows:

Compute the critical value of <em>z</em> for 90% confidence level as follows:

*Use a <em>z</em>-table.
Compute the 90% confidence interval of the population proportion as follows:


Thus, the 90% confidence interval of the population proportion is (0.43, 0.56).
Answer:
Daniel is rollerblading at 15 miles per hour
Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15
Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15
Step-by-step explanation:
Divide 235/5 so 47 check by doing 47 times 5 it checks so the answer is 47
