Answer:

Choice B and Choice C

Step-by-step explanation:

Hello! This is how I solved this question:

(10 x 8 x 2) + (3 x 3 x 4) = 160 + 36 = 196ft^3

(10 x 3 x 2) + (5 x 4 x 2) = 60 + 40 = 100ft^3

(8 x 4 x 2) + (3 x 6 x 2) = 64 + 36 = 100ft^3

(8 x 10 x 3) + (4 x 5 x 2) = 240 + 40 = 280ft^3

Choice B and Choice C are the same values, and knowing that you need two of the same values for the volume of the figure must be the same. Giving you your two answers from simply multiplying and adding the answers.

Hope this helps, don't hesitate to ask if you have additional inquiries!

-4(n - 6) = 12<br><br> Solve the Equation.

Romashka-Z-Leto [24]

-4(n - 6) = 12

n - 6 = -12/4 divide both sides by -4

n - 6 = -3

n = -3 + 6 add both sides by 6

n = 3

hope that helps, God bless!

The weights of a certain brand of candies are normally distributed with a mean weight of 0.8544 g and a standard deviation of 0.

aleksandr82 [10.1K]

Answer:

The probability is 0.508 = 50.8%.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Normally distributed with a mean weight of 0.8544 g and a standard deviation of 0.0525 g.

This means that $\mu = 0.8544, \sigma = 0.0525$

If 1 candy is randomly selected, find the probability that it weighs more than 0.8535 g.

This is 1 subtracted by the pvalue of Z when X = 0.8535. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{0.8535 - 0.8544}{0.0525}$

$Z = -0.02$

$Z = -0.02$ has a pvalue of 0.492

1 - 0.492 = 0.508

The probability is 0.508 = 50.8%.

Is a measure of 25 inches "far away" from a mean of 16 inches? As someone with knowledge of statistics, you answer "it depen

erik [133]

Answer:

a) 25 is 3 standard deviation from the mean

b) Is far away from the mean, only 0,3 % away from the right tail

c) 25 is pretty close to the mean (just a little farther from 1 standard deviation)

Step-by-step explanation:

We have a Normal Distribution with mean 16 in.

Case a) we also have a standard deviation of 3 inches

3* 3 = 9

16 (the mean) plus 3*σ equal 25 in. the evaluated value, then the value is 3 standard deviation from the mean

Case b) 25 is in the range of 99,7 % of all value, we can say that value is far away from the mean, considering that is only 0,3 % away from the right tail

Case c) If the standard deviation is 7 then

mean + 1*σ = 16 + 7 =23

25> 23

25 is pretty close to the mean only something more than 1 standard deviation
