1. For each problem, use the properties of inequalities to write a true inequality statement.

vlabodo [156]

Part a) The true inequality statement is: $-2>-5$

Part b) The true inequality statement is: $-4>-7$

Part c) The true inequality is $6$

Step-by-step explanation:

We are given the two integers are -2 and -5.

Part a)

Write a true inequality statement.

The true inequality statement is: $-2>-5$

Part b)

Subtract-2 from each side of the inequality. Write a true inequality statement.

Subtracting -2 from each side we get:

$-2>-5\\-2-2>-5-2\\-4>-7$

The true inequality statement is: $-4>-7$

Part c)

Multiply each number by-3. Write a true inequality statement.

Multiplying -3 on both sides:

$-2>-5\\-2*-3>-5*-3\\Multiplying\,\,-3\,\,will\,\,change\,\,the\,\,inequality\,\,sign\\6$

The true inequality is $6$

The average time an individual reads online national news reports is 49 minutes. Assume the standard deviation is 16 minutes and

Alexus [3.1K]

Answer:

11.70% probability someone will spend no more than 30 minutes reading online national news reports.

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:

$\mu = 49, \sigma = 16$
