Since the second angle + first angle is 90 degrees, the third angle must be 90 degrees to complete the 180 degrees in a circle.
Hope this helps!

According to the National Vital Statistics, full-term babies' birth weights are Normally distributed with a mean of 7.5 pounds a

Sav [38]

Answer:

68.26% probability that a randomly selected full-term pregnancy baby's birth weight is between 6.4 and 8.6 pounds

Step-by-step explanation:

Problems of normally distributed samples are 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:

$\mu = 7.5, \sigma = 1.1$

What is the probability that a randomly selected full-term pregnancy baby's birth weight is between 6.4 and 8.6 pounds

This is the pvalue of Z when X = 8.6 subtracted by the pvalue of Z when X = 6.4. So

X = 8.6

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

$Z = \frac{8.6 - 7.5}{1.1}$

$Z = 1$

$Z = 1$ has a pvalue of 0.8413

X = 6.4

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

$Z = \frac{6.4 - 7.5}{1.1}$

$Z = -1$

$Z = -1$ has a pvalue of 0.1587

0.8413 - 0.1587 = 0.6826

68.26% probability that a randomly selected full-term pregnancy baby's birth weight is between 6.4 and 8.6 pounds

Answer:

The answer to both photos is 1.

Step-by-step explanation:

Rise over run is looking at each plotted point on the graph and counting upward until level with the first point from zero, then going across the graph until you reach the plotted point.

The rise for the first picture is 3/1, and if you reverse them, you get, (1, 3).

The solution of the equation 3(p - 5) = 5p -27 is

inn [45]

Answer:

A) p = 6

Step-by-step explanation:

Given equation:

3(p - 5) = 5p -27

<u />

Apply the <u>Distributive Property of Multiplication over subtraction law</u>:

⇒ 3 · p - 3 · 5 = 5p - 27

⇒ 3p - 15 = 5p - 27

Add 27 to both sides:

⇒ 3p - 15 + 27 = 5p - 27 + 27

⇒ 3p + 12 = 5p

Subtract 3p from both sides:

⇒ 3p - 3p + 12 = 5p - 3p

⇒ 12 = 2p

⇒ 2p = 12

Divide both sides by 2:

⇒ 2p ÷ 2 = 12 ÷ 2

⇒ p = 6
