Answer:

<h2>r ≤ 0</h2>

Step-by-step explanation:

13 - r ≥ 13           <em>subtract 13 from both sides</em>

13 - 13 - r ≥ 13 - 13

-r ≥ 0       <em>change the signs</em>

r ≤ 0

11. Higher Order Thinking Using what you know
Lynna [10]

Answer:

m∠1 + m∠3 = m∠2 + m∠4

Step-by-step explanation:

In the figure attached,

In the given trapezoid if two sides AB and CD are parallel and AD is a transverse,

m∠1 + m∠3 = 180°

Similarly, if AB and CD are parallel and BC is a transverse,

m∠2 + m∠4 = 180°

Therefore, m∠1 + m∠3 = m∠2 + m∠4 is the relation between these angles.

If the mean of a normally distributed population is -10 with a standard deviation of 2, what is the likelihood of obtaining a va
ira [324]

Answer:

93.32% probability of obtaining a value less than or equal to -7.

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 = -10, \sigma = 2

What is the likelihood of obtaining a value less than or equal to -7?

This is the pvalue of Z when X = -7.

So

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

Z = \frac{-7 -(-10)}{2}

Z = \frac{3}{2}

Z = 1.5

Z = 1.5 has a pvalue of 0.9332.

So there is a 93.32% probability of obtaining a value less than or equal to -7.
