Dimas [21]

Answer:

B) 700 mg to 740 mg.

Step-by-step explanation:

Because the mean is the average of a data set, it means that there must be data above and below this value.

If the average is 720 mg, in the range there must be values that exceed this value and others that are below this.

We will analyze each of the options.

A) 740 mg to 780 mg.

There are values above 720, but not below 720.

B) 700 mg to 740 mg.

In this case, there are values below and above 720.

C) 680 mg to 720 mg.

There are only values below 720.

D) 660 mg to 700 mg.

There are only values below 720.

E) 620 mg to 660 mg.

There are only values below 720.

Therefore the answer is B) 700 mg to 740 mg. Since it fulfills the premise that guarantees the mean.

The heights of adult men in America are normally distributed, with a mean of 69.8 inches and a standard deviation of 2.69 inches

Brilliant_brown [7]

Answer:

a) 1.93

b) 97.32% of men are SHORTER than 6 feet 3 inches

c) 2.71

d) 0.34% of women are TALLER than 5 feet 11 inches

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

a. If a man is 6 feet 3 inches tall, what is his z-score (to two decimal places)?

For man, $\mu = 69.8, \sigma = 2.69$

A feet has 12 inches, so this is Z when X = 6*12 + 3 = 75. So

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

$Z = \frac{75 - 69.8}{2.69}$

$Z = 1.93$

b. What percentage of men are SHORTER than 6 feet 3 inches?

Z = 1.93 has a pvalue of 0.9732

97.32% of men are SHORTER than 6 feet 3 inches

c. If a woman is 5 feet 11 inches tall, what is her z-score (to two decimal places)?

For woman, $\mu = 64.1, \sigma = 2.55$

Here we have X = 5*12 + 11 = 71.

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

$Z = \frac{71 - 64.1}{2.55}$

$Z = 2.71$

d. What percentage of women are TALLER than 5 feet 11 inches?

Z = 2.71 has a pvalue of 0.9966

1 - 0.9966 = 0.0034

0.34% of women are TALLER than 5 feet 11 inches

Describe a real world situation that is modeled by dividing two fractions or mixed numbers

Oduvanchick [21]

Hey there!
If you have a granola bar, and you've already eaten half of it and your 4 friends come up to you asking for equal pieces, you'd have to divide 1/2 by 4 to ensure that they each get an equal amount, or 1/8 of the bar.
Hopefully this helps!

A net and 4 figures are shown. Which figure shown can be formed from the net. ( input the number only) please answer quick and e

AfilCa [17]

A net is pretty much a three dimensional shape unfolded into a flat construction. Imagine cutting the edges of a box and unfolding it so you can lay it flat on the ground. That would form a net for the 3D shape of the box.
In this case, 1 and 2 obviously aren't right since they would both involve triangles in their net. 3 is close, but the parts of the net wouldn't be completely equal. Therefore it has to be 4, the cube.
