Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 14 feet a

Evgesh-ka [11]

Answer:

11.8 % empty

Step-by-step explanation:

volume of cylinder : pi × r² × h

attention ! the question gives us diameter, so for radius we need to cut them in half.

Va = pi × (14/2)² × 9 = pi×49×9 = 1385.44236... ft³

Vb = pi × (10/2)² × 20 = pi×25×20 = 1570.79633... ft³

after filling B with everything in A there is still some empty volume in B

Vb empty = Vb - Va = 185.35397... ft³

so,

100% Vb = 1570.79633... ft³

1% Vb = 15.7079633... ft³

so, how often does 1% of the total volume of B fit into the remaining empty volume of B ?

185.35397... / 15.7079633... = 11.8%

What is the distance between the points(-4,-1) and (-6,8) in simplest radical form.

Serga [27]

$~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-4}~,~\stackrel{y_1}{-1})\qquad (\stackrel{x_2}{-6}~,~\stackrel{y_2}{8})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[-6 - (-4)]^2 + [8 - (-1)]^2}\implies d=\sqrt{(-6+4)^2+(8+1)^2} \\\\\\ d=\sqrt{(-2)^2 + 9^2}\implies d=\sqrt{85}$

Jiffy Mix in Chelsea, Michigan has a machine that fills the Jiffy Corn Muffin Mix boxes with Mix. It dispenses corn muffin mix w

gregori [183]

Answer:

(b) The middle 68% of Jiffy Corn Muffin Mix boxes contain between 9.90 ounces and 10.10 ounces of corn muffin mix.

(c) The percentage of Jiffy Corn Muffin Mix boxes containing more than 10.3 ounces or less than 9.7 ounces of corn muffin mix is 16%.

(d) The percentage of iffy Corn Muffin Mix boxes containing more than 10.2 ounces of corn muffin mix is 2.3%.

(e) The percentage of Jiffy Corn Muffin Mix boxes containing less than 10.1 ounces of corn muffin mix is 84%.

Step-by-step explanation:

Let the random variable X be defined as the amount of corn muffin mix in a Jiffy Corn Muffin Mix box.

The random variable X follows a Normal distribution with mean, μ = 10.0 ounces and standard deviation, σ = 0.10 ounces.

(b)

According to the Empirical rule, 68% of the data from a Normal distribution lies within one standard deviation of mean.

That is:

P (x₁ < X < x₂) = 0.68

P (μ - σ < Z < μ + σ) = 0.68

Then,

P (10.0 - 0.10 < Z < 10.0 + 0.10) = 0.68

P (9.90 < Z < 10.10) = 0.68

Thus, the middle 68% of Jiffy Corn Muffin Mix boxes contain between 9.90 ounces and 10.10 ounces of corn muffin mix.

(c)

Compute the probability that Jiffy Corn Muffin Mix boxes contain more than 10.3 ounces or less than 9.7 ounces of corn muffin mix as follows:

P (X > 10.3 ∪ X < 9.7) = 1 - P (9.7 < X < 10.3)

$=1-P(\frac{9.7-10.0}{0.10}$

Thus, the percentage of Jiffy Corn Muffin Mix boxes containing more than 10.3 ounces or less than 9.7 ounces of corn muffin mix is 16%.

(d)

Compute the probability of Jiffy Corn Muffin Mix boxes contain more than 10.2 ounces of corn muffin mix as follows:

$P(X>10.2)=P(\frac{X-\mu}{\sigma}>\frac{10.20-10.0}{0.10})$

$=P(Z>2)\\=1-P(Z$

Thus, the percentage of iffy Corn Muffin Mix boxes containing more than 10.2 ounces of corn muffin mix is 2.3%.

(e)

Compute the probability that a randomly selected Jiffy Corn Muffin Mix box contains less than 10.1 ounces of corn muffin mix as follows:

$P(X$

$=P(Z$

Thus, the percentage of Jiffy Corn Muffin Mix boxes containing less than 10.1 ounces of corn muffin mix is 84%.
