Answer:
-4f
Step-by-step explanation:
-8f+2f=-6f then -6f+2f (since its a positive number) = -4f
Answer:
42
Step-by-step explanation:
in order to find y, we need to find x.
180-65-62=53
x=53
we need to subtract 53-?=11
53-42=11
y=42
Answer:
Other Endpoint (x₂,y₂) = (16,25)
Step-by-step explanation:
We are given endpoint = (4,-9) and midpoint(10,8) we need to find the other endpoint of line segment.
Let other endpoint be (x₂,y₂)
The formula used to find other endpoint is using formula of midpoint
We have
Using formula and finding (x₂,y₂)
So, x₂=16 and y₂=25.
So, Other Endpoint (x₂,y₂) = (16,25)
Answer:
68% of all batteries will have a life between 32 months and 40 months.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 36.
Standard deviation = 4.
68% within 1 standard deviation of the mean.
36 - 4 = 32
36 + 4 = 40
68% of all batteries will have a life between 32 months and 40 months.
