-16 i think is the correct anwser because you take the old number then subtract the new number then divide the old one then multiply by 100
12 ÷ 4 = 3
So she hikes 3 kilometers per hour.
3 x 6 = 18
She hikes 18 kilometers in 6 hours.
Hope it helps!
Using concepts of the normal and of the uniform distribution, it is found that the correct option is:
The distribution is approximately Normal, with a mean of 8 ounces and a standard deviation of 1.2 ounces.
- In an uniform distribution, all outcomes are equally as likely, thus they have the same height.
- In the normal distribution, the outcomes with the highest likelihood are those closest to the mean, thus they have the highest height. This means that the mean of this distribution is 8.
- The standard deviation cannot be a negative value, so in this problem, it is 1.2, which means that the correct option is:
The distribution is approximately Normal, with a mean of 8 ounces and a standard deviation of 1.2 ounces.
