According to time, texting speed is a two-variable type of data that's represented by a scatterplot. This is because a scatterplot helps graph the data points, so that you can figure out and interpret the relationship.

The other answer is the sample response, so it's better to put it in your own words. :)

Heather works part time at a movie theater where she earns $7.00
Nastasia [14]

Answer:

d. 1 grid equals 1 hour

Step-by-step explanation:

When plotting research data,  X-axis(or horizontal axis) usually used for independent variable and Y-axis is used for the dependent variable. In this case, Heather wants to know how much earning on different numbers of hours. The dependent variable is the earning and the independent variable is the hours, so you put hours on the horizontal axis.

You want to make a 10x10 grid of data and the hours ranged between 1-10. If you plot them equally, approximate scale will be: (10h-1h)/(10)= 0.9h/grid

The closest option is 1 hour per grid. It will provide the best visualization since it won't stretch or minimize the data too much.

Math Question:<br> Pls help I will do anything

Answer:

The probability of spinning red is \frac{1}{3}, the probability of spinning a 1 is \frac{1}{6}, the probability of spinning an odd number is \frac{1}{2}, and the probability of spinning a 9 is 0.

Step-by-step explanation:

Since there are a total of 6 possible outcomes, you can use this in the following questions. There are 2 red tiles, so the probability of spinning red is \frac{2}{6} or \frac{1}{3}. Since there are only one 1 tile, the probability of spinning a 1 is \frac{1}{6}. Since there are three odd numbers, the probability of spinning an odd number is \frac{1}{2}. Since there are no 9 in the spinner, the probability of spinning a 9 is 0 or never.

Answer:The area is 14306. 625 cm.

Step-by-step explanation:

To find the area of the circle, we will need to find the diameter and find the radius.

So we know the circumference is  423.9 m and we know to get the circumference, you will need to multiply pie by the diameter .

so now we need divide the circumference by pie to find the diameter.

423.9/ 3.14 = 135  so 135 is the diameter.

To find the radius we need to divide the diameter by 2.

135/2 = 67.5

Now is time to find the area which uses the formula  A= nr^2

A = 3.14 * 67.5^2

A = 14306. 625
