Answer:
Kindly check explanation
Step-by-step explanation:
Given the data showing the relationship between GPA and hours of study :
From the regression model given :
Regression equation is:
y = 0.141x + 1.096
Also, the regression Coefficient, R = 0.957
a) Describe how the line of best fit and the correlation coefficient can be used to determine the correlation between the two variables on your graph.
From the regression equation, we can infer if the relationship or correlation between the two variables is positive or negative from the value of the slope, a positive slope Value means a positive relationship while a negative slope value means a negative relationship.
The Correlation Coefficient, R also gives the strength of relationship, with values close to - 1 or 1 depicting a strong relationship while positive and negative R values also depictava positive or negative relationship.
Here there is a strong positive relationship between GPA and Hours.
Correlation does not imply causation. Correlation only shows the type of relationship between variables and it does not mean that high GPA values are causes by long hours of study and vice versa.
Answer: (c)
Step-by-step explanation:
Given
The function is
Range of a function describes the values y can take
from the graph it is clear that the maximum value of y is 5
Hence. option (c) is correct.

Answer:
<u>239 students and 153 non-students attended to the school production of "Our Town"</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Number of tickets of the school production sold = 392
Student ticket cost = US$ 3
Non-students ticket cost = US$ 5
Total collected = US$ 1,482
2. How many students and how many non-students attended?
For answering the question we will use the following equation:
x = Number of students that attended the school production
392 - x = Number of non-students that attended the school production
3x + (392 - x) * 5 = 1,482
3x + 1,960 - 5x = 1,482
-2x = 1.482 - 1,960
-2x = - 478
x = -478/-2
<u>x = 239 ⇒ 392 - 239 = 153</u>
<u>239 students and 153 non-students attended to the school production of "Our Town"</u>
Answer:
<em>mBAD = 244°</em>
Step-by-step explanation:
<em>~ Let us calculate the two unknown angles, represented by two lines each. These two lines are shared by each angle such that they are congruent ~</em>
m∠ APE = x = m∠ EPD,
360 - 136 = m∠ APE + m∠ EPD + 42 + 74,
224 = x + x + 42 + 74,
224 = 2x + 116,
2x = 108,
x = 54 = m∠ APE = m∠ EPD
Now that we know the measure of these unknown angles, let us solve for the degree measure of arc BAD, as such:
mBAD = m∠ BPA + m∠ APE + m∠ EPD,
mBAD = 136 + 54 + 54,
<em>mBAD = 244°</em>
