Since 68% of the sample ranges from the plus minus first standard deviation from the mean, then interval wherein it will occur will be between 53.5% to 60.5%. I got this answer through adding and subtracting one standard deviation (3.5) from the mean (which is 57).
Answer:
6
Step-by-step explanation:
Call pentagon p, circle c and triangle t
We have 2c + 2p = 2p + 2t + c
p = 5, t = 3 so
2c + 2(5) = 2(5) + 2(3) + c
2c + 10 = 10 + 6 + c
2c = 6 + c
c = 6
Step-by-step explanation:
A) The bus rental would be the total cost or "C". So 700=250+3m.
B) Solve with properties of equality:
700 - 250 = 250 + 3m - 250
450 = 3m
450/3 = 3m/3
150 = m
150 miles
C) Check your answer by plugging the answer into the original equation:
C = 250 + 3(150)
C = 250 + 450
C = 700
