3. DC SPORTS Inc ships sports balls around the world. A bowing boll hos a diameter of

hram777 [196]

Answer:

50 softballs

Step-by-step explanation:

Volume of a sphere = (4/3)*π*radius³

A bowling ball has a radius of 8.5/2 = 4.25 in

Volume of a bowling ball = (4/3)*π*4.25³ = 321.56 in³

Circumference of a circle = 2*π*radius

radius of the basketball = Circumference/(2*π)

radius of the basketball = 29.5/(2*π) = 4.7 in

Volume of the basketball = (4/3)*π*4.7³ = 434.9 in³

radius of the softball= 12/(2*π) = 1.9 in

Volume of 50 softballs= 50*(4/3)*π*1.9³ = 1436.55 in³

A golf ball has a radius of 1.7/2 = 0.85 inches

Volume of 48 (four dozens) golf balls= 48*(4/3)*π*0.85³ = 123.48 in³

Cran-soy trail mix cost $2.99 for 5 ounces, raisin-nuts mix costs $3.41 for 7 ounces, lots of cashews mix costs $7.04 for 8 ounc

ss7ja [257]

First of all we will find per ounce price of each trail mix.

Let us find per ounce price of cran-soy trail mix.

$\text{Cran-soy trail mix cost per ounce}=\frac{2.99}{5}$

$\text{Cran-soy trail mix cost per ounce}=0.598$

Now we will find per ounce cost of raisin-nuts mix.

$\text{Raisin-nuts mix cost per ounce}=\frac{3.41}{7}$

$\text{Raisin-nuts mix cost per ounce}=0.487142857\approx 0.487$

Let us find per ounce price of lots of cashews mix.

$\text{Lots of cashews mix cost per ounce}=\frac{7.04}{8}$

$\text{Lots of cashews mix cost per ounce}=0.88$

Now we will find per ounce cost of nuts for you mix.

$\text{Nuts for you mix cost per ounce}=\frac{2.40}{6}$

$\text{Nuts for you mix cost per ounce}=0.4$

Now let us order our trail mix brands from least expensive to most expensive by their per ounce price.

Nuts for you (0.4), Raisin-nuts mix (0.487), Cran-soy trail mix (0.598), Lots of cashews mix (0.88).

Select the correct answer for the blank: If everything else stays the same, the required sample size ____ as the confidence leve

Vikentia [17]

Answer:

The required sample size increases.

Step-by-step explanation:

The margin of error of a confidence interval is given by:

$M = z*\frac{\sigma}{\sqrt{n}}$

In which z is related to the confidence level(the higher the confidence level the higher z), $\sigma$ is the standard deviation of the population and n is the size of the sample.

In this question:

The confidence level decreases, so z decreases.

For the margin of error to stay the same, the sample size also has to decrease.

The required sample size increases.
