Answer:
The correct answer is = p = 15 and q = 6.
Step-by-step explanation:
Given:
Perimeter of rectangle = 42 cm
p - q = 9 cm
length = p
width = q
we know:
Perimeter of rectangle= 2(l+w)
solution:
42 = 2(P+q)
21= p+q
Difference of p and q = 9 cm.
Then, P+q=21 .... 1
P-q=9 ....2
Adding both 1 and 2
2P = 30
P= 15cm and
q = 15-9
= 6cm
The sampling distribution standard deviation is the population standard deviation divided by the root of the sample size.
sampling distribution standard deviation = 6.00/√36 = 1.00
Answer:
36
Step-by-step explanation:
1^3 + 2^3 + 3^3= 1+8+27
9+27= 36
Subtract all the operating expenses from the amount he spent total and get what's left over is $491. That's what he spent on gas. Divide the number of miles he drove by the amount he spent on the gas to find out what the average cost of the gas was per mile. 491/7270 = .06753. But that is expressed in dollars and we need it in cents. Multiply that decimal by 100 to get 6.75 cents, choice A from above.
