A track coach made a two way table to show his runners gender and running category. Male: Sprints- 16 Middle distance- 11 Long d

hram777 [196]

There are 9 long distance male runners and 5 long distance female runners. This makes a total of 9+5 = 14 long distance runners.

Out of this total of 14 long distance runners, there are 9 males. So the probability as a fraction is 9/14

If you need the answer in decimal form, then use a calculator to get 9/14 = 0.642857 which is approximate.

You are choosing between two health clubs. Club A offers membership for a fee of $ 28$28 plus a monthly fee of $ 20.$20. Club B

eimsori [14]

Answer:

That is to say that at 3 months, the values of the club are equal.

Club A = 268 dollars in total

Club B = 295 dollars in total

Step-by-step explanation:

The first thing is to propose an equation for each club. Let m be the number of months.

Club A = 28 + 20 * m

Club B = 19 + 23 * m

Now, to know when it is the same, we must equal the value of Club A with Club B, it would look like this

28 + 20 * m = 19 + 23 * m

By rearranging the equation we have:

23 * m - 20 * m = 28-19

3 * m = 9

m = 3

That is to say that at 3 months, the values of the club are equal.

Now to know the total value, we will do it with an annual membership, which would be a total of 12 months, therefore it is to replace in the equation of each one:

Club A = 28 + 20 * 12 = 268 dollars in total

Club B = 19 + 23 * 12 = 295 dollars in total

Which of the following are true about regression with one predictor variable (often called "simple regression")? Check all that

AfilCa [17]

Answer:

<h3>A. The slope describes the amount of change in Y for a one-unit increase in X .</h3><h3>B. The regression equation is the line that best fits a set of data as determined by having the least squared error.</h3>

Step-by-step explanation:

In statistics, linear regression is a analysis we do to describe the relationship between two variables. With this study, we pretend to know if there's a positive or negative correlation between those variables, if that correlation is strong or weak.

In a linear regression analysis, we modeled the data set using a regression equation, which is basically the line that best fits to the data set, this line is like the average where the majority of data falls. That means choice A is right.

When we use linear equations, we need to know its characteristics, and the most important one is the slope, which is the ratio between the dependent variable and the independent variable. Basically, the slope states the unit rate between Y and X, in other words, it states the amount of Y per unit of X. That means choice B is correct.

Therefore, the correct answers are A and B.

AB and BC are tangents of circle P. What is the value of x?

koban [17]

There are several information's already given in the question. It is very important to look at the attached diagram very closely. The angle given in the question is 73 degrees.
Then
x = 180 - 73
= 107 degrees
I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
