Answer:

8482.3 inches

Step-by-step explanation:

You have to find the circumference of the wheel.

If the radius is 13.5, the diameter is 27 (13.5 x 2).

C = πd

C = π × 27

C = 27π

100 rotations means 27π × 100 = 2700π

= 8482.3 inches

Answer:

The average bag weight must be used to achieve at least 99 percent of the bags having 10 or more ounces in the bag=9.802

Step-by-step explanation:

We are given that

Standard deviation, $\sigma=0.2$ ounces

We have to find the average bag weight must be used to achieve at least 99 percent of the bags having 10 or more ounces in the bag.

$P(x\geq 10)=0.99$

Assume the bag weight distribution is bell-shaped

Therefore,

$P(\frac{x-\mu}{\sigma}\geq 10)=0.99$

We know that

$z=\frac{x-\mu}{\sigma}$

Using the value of z

Now,

$\frac{10-\mu}{0.2}=0.99$

$10-\mu=0.99\times 0.2$

$\mu=10-0.99\times 0.2$

$\mu=9.802$

Hence, the average bag weight must be used to achieve at least 99 percent of the bags having 10 or more ounces in the bag=9.802

an ivy plant was 19 inches long. two years later it was 33 inches long. what was the percent increase to the nearest hundredth o

lapo4ka [179]

Answer:

73.68%

Step-by-step explanation:

To find the amount of increase subtract 33-19 to get 14.

The percent increase is the amount of increase/initial length * 100

So 14/19*100 = 73.684...

Rounding to the nearest hundredth = 73.68%
