Answer:
At least 68% of observations lie between 22 and 26 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 = 24
Standard deviation = 2
22 = 24 - 2
22 is one standard deviation below the mean
26 = 24 + 2
26 is one standard deviation above the mean.
So, by the empirical rule, at least 68% of observations lie between 22 and 26 months.
I would say C. 5.516 m.

Answer:
11x + 11
Step-by-step explanation:
11x
11
=11x + 11
From least to greatest is square root of 3, square root of 5, 22/7 , 16/4
hope it help
A)
x=sales
4/100 x + 400≥460
b)
Solve the inequation:
4/100 x+400≥460
lest common multiple= 100
4x+40000≥46000
4x≥46000-40000
4x≥6000
x≥6000/4
x≥1500
answer: the minimun amount tha se will needs to sell is $1500.
