The scale factor of figure JKLMN to figure PQRST is 3:2. If KL = 9 cm and MN = 15 cm, what is the length of side ST?

Lina20 [59]

Since the scale factor is 3:2, and MN is 15, we can solve this.

The answer is 10.

A sector with a central angle measure of 7pi/4 (in radians) has a radius of 16 cm

strojnjashka [21]

Answer:

Area of sector = 704 cm ²

Step-by-step explanation:

Given:

Central angle = 7pi/4 (in radians)

Radius = 16 cm

Find:

Area of sector = ?

Computation:

Central angle = $\frac{7}{4}\pi \times \frac{180}{\pi } =315$

$Area\ of \ sector=\frac{\theta}{360}\pi r^2\\\\Area\ of \ sector=\frac{315}{360}\pi 16^2\\\\Area\ of \ sector=704 cm^2$

Area of sector = 704 cm ²

Mr thomas puts up fence posts from one end to another equal distances apart.there are 27 posts the width of each part is 10 cent

Fittoniya [83]

If there are 27 posts, then there are (n - 1) total spaces between the posts . . . 27 - 1 = 26 total spaces (since there has to be a post at each end of the line)

Here's an example of 7 posts equally spaced . . . so you can see there are one less spaces between posts than there are posts (i.e. 6 total spaces between 7 posts) . . .

[] . . . [] . . . [] . . . [] . . . [] . . . [] . . . []

27 posts = 27*(10cm) = 270 cm = 2.7m
26 spaces = 26*(30m) = 780 m

<u><em>Length of Fence = L = 780m + 2.7m = 782.7m</em></u>

Suppose the weights of apples are normally distributed with a mean of 85 grams and a standard deviation of 8 grams. The weights

user100 [1]

Answer:

a) 0.0304 = 3.04% probability a randomly chosen apple exceeds 100 g in weight.

b) The weight that 80% of the apples exceed is of 78.28g.

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.

Weights of apples are normally distributed with a mean of 85 grams and a standard deviation of 8 grams.

This means that $\mu = 85, \sigma = 8$
