Answer:

Answer = 3053.63

Step-by-step explanation:

The formula for finding the volume of a sphere is : V = 4/3 πr³

V = 4/3· π · $9^{3}$

≈ 3053. 62806

Rounded to the hundreths place is 3053.63.

Answer: 6.3 m

Step-by-step explanation:

"8% more" = 1.08 (which is 1+0.08). "10% less" = 0.90 (which is 1-0.10).

first = 5.25

her_best = 1.08*first

her_best = 0.90*winning

Substitute to determine the winning jump's length.

winning = 1.08*5.25/0.90 = 6.3

So, the winning jump was 6.3 meters.

The volumes of soda in quart soda bottles are normally distributed with a mean of 32.3 oz and a standard deviation of 1.2 oz. Wh

Mashcka [7]

Answer: 0.4013

Step-by-step explanation:

Given : The volumes of soda in quart soda bottles are normally distributed with : $\mu=32.3\text{ oz}$

$\sigma=1.2\text{ oz}$

Let x be the volume of randomly selected quart soda bottle.

z-score : $z=\dfrac{x-\mu}{\sigma}$

$z=\dfrac{32-32.3}{1.2}=-0.25$

The probability that the volume of soda in a randomly selected bottle will be less than 32 oz = $P(x$

$=0.4012937\approx0.4013$

Hence, the probability that the volume of soda in a randomly selected bottle will be less than 32 oz is 0.4013
