The types of correlation seen between positive correlation, negative correlation, or no correlation, in the variables is:

  • a. Height of a person and how often he or she attends religious services. - No correlation
  • (b.)Average property tax in a school district and salary of teachers - Positive correlation
  • (c.)Weight of a person and shoe size. - Positive correlation

<h3>What is the correlation between property taxes and teacher salaries?</h3>

One of the main sources of funding for school districts is the property tax charged. This means that increased property taxes will lead to more money being available for teacher salaries which might then increase. There is therefore a positive correlation between the two.

The same is true for the weight of a person and shoe size. This is because the heavier a person is, the larger their shoe size according to research.

There is however no correlation between the height of a person and their attendance of religious services.

You are giving the following amounts: $190,258.50; $152,698.00; $122,753.00; $220,523.00; $231,951.00. What is the average of th
Pie
This is a really simple problem once you understand how to solve it, and that's what I'm going to show you! :)

When calculating the mean (average) of multiple numbers, your first step is to add the numbers together.
190,258.50 + 152,698.00 + 122,753.00 + 220,523.00 + <span>231,951.00 = 918,183.50

Then you take the sum of your numbers, and divide the sum by the amount of numbers added, which in your case, is 5.

918,183.50/5 = 183,636.70

The average of these numbers is $183,636.70

Answer:

C and $320.45

Step-by-step explanation:

I think it's C because this is the full function :

b = 26 \times d + 3.5 \times 13 + 14.95

And to get the b part of the question i just put the number in

b = 26 \times 10 + 3.5 \times 13 + 14.95 = 320.45

I'm not a 100% sure, sorry if it's wrong
