Explain how to use the distributive property to find an expression that is equivalent to 20+10

A. A business is attempting to find the best small town in the United States in which to relocate. As part of the investigation, the elevations of all small towns in the United States are researched. Some towns are located high in the Rockies with elevations over 8,000 feet. There are even some towns located in the south central valley of California with elevations below sea level. These elevations can best be described as which level of datab. The unemployment rate is often used as an indicator of a community’s economic vitality. An unemployment rate is best described as what level of measurement?

Every morning Jack flips a fair coin ten times. He does this for anentire year. LetXbe the number of days when all the flips come out the same way(all heads or all tails).(a) Give the exact expression for the probabilityP(X >1).(b) Is it appropriate to approximateXby a Poisson distribution

**Step-by-step explanation:**

You have to use PEMDAS

first p, parenthesis

12-2=10

then e exponenets 3^3=9

and finally d diviison /2

so 9(10) : 2

=90/2

=45

**Answer:**

4.75% probability that the average (mean) reaction time of the 4 operators exceeds 1.25 seconds.

**Step-by-step explanation:**

**Central Limit Theorem**

The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size can be approximated to a normal distribution with mean and standard deviation

**Normal probability distribution**

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean and standard deviation , the zscore of a measure X is given by:

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:**

**What is the probability that the average (mean) reaction time of the 4 operators exceeds 1.25 seconds?**

This is 1 subtracted by the pvalue of Z when X = 1.25. So

has a pvalue of 0.9525.

So there is a 1-0.9525 = 0.0475 = 4.75% probability that the average (mean) reaction time of the 4 operators exceeds 1.25 seconds.

**Answer:**

**y = -1/2x + 1/2**

**Step-by-step explanation:**

Step 1: Write in known variables

y = -1/2x + b

Step 2: Find *b*

2 = -1/2(-3) + b

2 = 3/2 + b

b = 1/2

Step 3: Rewrite equation

**y = -1/2x + 1/2**
