Eloise is creating a game for her Strategic Games option.
Her square game board will have 64 squares on the inside and a decorative border around the outside edge.
What is the length of the border?
What assumptions can you make?

Answers

I am 99% sure.
64 square would suggest that sides of square are 8 “units”.
A=a^2
64=8•8
If decorative border is all around square (1 “unit”) that would make a length of a border: 8•2+10•2=16+20+36.
Good luck.

This scatter plot shows the relationship between the number of sweatshirts sold and the temperature outside

Answers

Answer:

y intercept: 250

slope: -10/3

Step-by-step explanation:

y intercept is where x = 0

slope is found by using the equation (y2 - y1) / (x2 - x1) = (200 - 250) / (15-0) = -50 / 15 = -10 / 3

The y intercept of the scatterplot is 250 sweat shirts and the slope is (10/3)

What is a linear function?

A linear function is in the form:

y = mx + b

Where m is the rate of change and b is the y intercept.

Let y represent the number of sweat shirts sold and x represent the temperature.

The y intercept is at (0, 250).

Using point (0, 250) and (15, 200):

Slope = (200 - 250) / (15 - 0) = 10/3

The y intercept of the scatterplot is 250 sweat shirts and the slope is (10/3)

2x-7=27

move -7 to other side by adding it (to the other side)

2x= 7+27

2x= 34

divide by 2 (on both sides) to get x by itself

a random selection of indoors and outdoors pool managers are surveyed about the number of people in each age group that swim there. results from the survey are displayed in the two way table. based on the data, does there appear to be an association between pool type and age group? explain your reasoning​

Answers

Answer:

Step-by-step explanation:

Based on the data shown, there seems to be a very small association between age and pool type. Younger individuals seem to mainly prefer outdoor pools. Older individuals seem to still prefer outdoor pool but with a large percentage of that group preferring indoor pools, roughly 46%. This can be due to many reasons such as warmer temperatures in indoor pools, but there is not enough information to determine the reasoning.
