Answer:
x=12.50
y = 17.50
Step-by-step explanation:
x = Amount of one Derek withdrawal
then amount of John withdrawal =x+5
Total withdrawals of Derek = no of times x one time withdrawal
= 7(x) = 7x ... i
No of John withdrawal = no of times x one time withdrawal
= 5(x+5) ... ii
Given that i and ii are equal
i.e. 7x =5(x+5)
7x = 5x+25
2x =25
x = 12.50 dollars
Y = 17.50 dollars
Checking part:
total derek withdrawal = 7(12.5) =87.50
Joh's withdrawal = 5(17.50) = 87.50
Since both are equal, our answers are right.
Solution: Derek withdrew each time 12.50 dollars each for 7 times and John withdrew 17.50 dollars each for 5 times.

Answer:
H0: mu = 5
Ha: mu > 5
Step-by-step explanation:
A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) upon testing.
It is expressed using the equality sign.
An alternate hypothesis is also a statement from a population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected.
It is expressed using any of the inequality signs.
Answer:
7 inches
Step-by-step explanation:
Using Pythagoras' theorem on the right triangle, that is
r² + 11² = 13²
r² + 121 = 169 ( subtract 121 from both sides )
r² = 48 ( take the square root of both sides )
r = 
≈ 7 in ( to the nearest inch )
