Step-by-step explanation:
We see that every time our x-value increases, our y-value decreases. Therefore, we know we would have a negative slope.
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.
Find the area of the lawn: (30 yd)(25 yd) = 750 yd^2.
Then divide this result by (1 bag)/ 100 yd^2. You end up with 7.5 bags.
