Okay where’s the question smarty
At this rate she runs 9 miles an hour
Hope this helps!
The statement (d) Alaric's maths grade is the response variable is correct because maths grade is a dependent variable.
<h3>What is an explanatory variable?</h3>
It is defined as the variable which is independent. They show the expected results and the result is known as the response variable which is dependent on the explanatory variable.
We have given:
Alaric wants to determine if he can get a better grade in maths by studying for longer periods of time.
The duration of the experiment is 4 weeks which is known or constant.
But the number of hours she studied is a variable, and it is independent.
The maths grade is the dependent variable which is on the number of hours Alaric study variable.
Thus, the statement (d) Alaric's maths grade is the response variable is correct because maths grade is a dependent variable.

- B'(-5, 2)
- C'(-9, 2)
- D'(-9, 6)
Step-by-step explanation:
Rotation 180° about the origin <em>changes the sign of every coordinate</em>. The image coordinates are shown above.
Answer:
<stv=153
Step-by-step explanation:
stu+stv=180 (being a straight angle)
3b +15b+18=180
18b=180-18
b=162/18
b=9
now
<stv=15b+18
=15 × 9 +18
=135+18
=153
<stv=153°
