Answer:

The answer is B.

Step-by-step explanation:

The question asks us to select an explanatory variable and a response variable which are just different names for independent and dependent variables.

Explanatory or independent variables, as the name suggests, are not affected by any other variable in the equation.

Response or dependent variables change according to the changes in other variables in the equation.

Out of the four options given in the question, the option b should be chosen according to the requirements because diameter of the apple affects its weight but the diameter itself is independent of the weight variable.

The plot should show that the weight changes according to the diameter variable.

I hope this answer helps.

Your teacher is choosing 2 students to run an errand for her. There are 12 girls and 10 boys in the class. What is the probabili
Ne4ueva [31]

Answer:

2/7

Step-by-step explanation:

There are 22 (12 + 10) total students in the class. That means that the chance of the first student picked being a girl is 12/22.

Now, we must calculate the chance of the next student to be picked <em>also </em>being a girl - however, there is a trap here! Remember that since a girl has been picked, the total student pool has decreased to 21 and and the total number of girls has decreased to 11. This means the new chance of girl being picked is 11/21.

To find the probability of both these events happening in conjunction, these fractions must be multiplied. 12/22 * 11/21 = 132/462, which simplifies to 2/7.
