Answer:

$\boxed{V = 3591.4 \ cm^3}$

Step-by-step explanation:

Diameter = 19 cm

Radius = 19/2 = 9.5 cm

Volume = $\frac{4}{3} (3.14)(9.5)^3$

V = $\frac{4}{3}(3.14)(857.375)$

V = $\frac{10774}{3}$

V = 3591.4 cm³

<span>Since there was a dilation, the two triangles will be similar. The scale factor is less than one and is a reduction, therefore, the image will be smaller than the pre-image.

Answer:

Test scores of 10.2 or lower are significantly low.

Test scores of 31.4 or higher are significantly high.

Step-by-step explanation:

Problems of normally distributed samples can be solved using 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.

In this problem, we have that:

$\mu = 20.8, \sigma = 5.3$
