Kevin says that “a line segment is the part of a line containing two endpoints.” What additional information is needed to make t
kakasveta [241]

The statement "That does not extend in both directions." will make the definition, precise.

Kevin's line segment definition is correct.

However, the end points in a line segment implies that the line segment does not extend past its two end points.

So, to make it precise;

Kevin needs to include that the line segment does not extend in both directions, in the definition.

Hence, option (c) is correct.

For bone density scores that are normally distributed with a mean of 0 and a standard deviation of​ 1, find the percentage of sc
mr Goodwill [35]
<span>In a normal distribution 68.27% of the values are within one standard deviation from the mean, 95.5% of the values are within two standard deviations from the mean, and 99.7 % of the values are within three standard deviations of the mean

With that you have the answer to the three questions:

</span>
<span>a. significantly high​ (or at least 2 standard deviations above the​ mean).

99.5% of the values are within 2 standard deviations from the mean, half of 100% - 95.5% = 4.5% / 2 = 2.25% are above the mean, so the answer is 2.25%

b. significantly low​ (or at least 2 standard deviations below the​ mean).

The other half are below 2 standard deviations, so the answer is 2.25%

c. not significant​ (or less than 2 standard deviations away from the​ mean).

As said, 95.5% are within the band of two standard deviations from the mean, so the answer is 95.5%.

when Mrs. Stewart makes pie dough, she uses 2/3 cup of shortening for every 2 1/2 cups of flour which proportion could be used t
Scrat [10]

Answer:

The amount of floor Mrs.Stewart needs for 5 cups of shortening =\frac{75}{4} =18\tfrac{3}{4} cups.

Step-by-step explanation:

Mrs.Stewart pie dough needs \frac{2}{3} cups of shortening for 2\tfrac{1}{2}=\frac{5}{2} cups of flour.

Now we assume that the shortening needed for x cups of flour is y cups.

Accordingly we can arrange the ratios.

\frac{cups\ of flour\ (x)}{cups\ of\ shortening\ (y)} =\frac{x}{y} =\frac{5/2}{2/3}

Plugging the value of y=5 as it is number of cups of shortening Mrs.Stewart have used.

And multiplying both sides with 5,we have

Number of cups of flour (x) =\frac{x}{y} =\frac{5/2}{2/3}

So (x) =\frac{5\times 3\times 5}{2\times 2} =\frac{75}{4} = 18\tfrac{3}{4}

The amount of floor Mrs.Stewart needed for 5 cups of shortening = 18\tfrac{3}{4}\ cups.
