Answer:
0+1+2+3+4+5+6=21
Step-by-step explanation:
Since integers are given as x1, x2, x3, x4, x5, x6, and x7. This means they are consecutive integers divisible by 7.
Thus no matter which 7 consecutive integers are these, their reminders will always be in the order of 0,1,2,3,4,5 & 6.
So their sum will be 0+1+2+3+4+5+6=21.
Answer:
Step-by-step explanation:
Given that the weights for a population of North American raccoons have a bell-shaped frequency curve with a mean of about 12 pounds and a standard deviation of about 2.5 pounds
Since bell shaped is given we can assume that this follows a normal distribution symmetrical about the mean.
To find 95% two values we can use Z critical value for 95%
i.e. ±1.96
95% will lie between 12±1.96(2.5)
= 12±4.9
=(7.1, 16.9)
B. no mileage restrictions
C. lower interest rates
D. no value depreciation
E. lower maintenance costs
Answer:
B
Step-by-step explanation:
Answer:
(2a-5b)^2
Step-by-step explanation:
4a^2 - 20ab + 25b^2 = (2a)^2 - 2*2a*5b + (5b)^2 = (2a-5b)^2
