Ghella [55]

Answer:

Study 2

Step-by-step explanation:

Okay, so in this question we are given the data or parameters or information Below;

=>" two studies were conducted on the effectiveness of a peer mentoring program."

=> "Self-evaluation ratings among participants before, during, and after the program were measured in both studies."

=> In Study 1, 12 participants were observed"

=> "Study 2, 16 participants were observed."

=> " If Fobt = 3.42 in both studies"

Say Vo = study 2 and V1 = study 1.

Hence, Vo: not effective.

V1 = effective.

The study in which the decision will be to reject the null hypothesis at α= 0.05 level of significance is the STUDY 2.

This is because the value of F > f-critical.

The points (3,5) and (21,35) form a proportional relationship. Find the slope of the line through thepoints. Then use the slope
ICE Princess25 [194]

\begin{gathered} \text{ The slope of a line that passes through 2 points is } \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{35-5}{21-3} \\ m=\frac{30}{18} \\ m=\frac{5}{3} \end{gathered}

The slope is 5/3

For the graph, we have to see that (3,5) and (21,35) are in the line, , or that the equation of the line is

y=\frac{5}{3}x

In the case A), a point in the line is (3,5) so the answer is A.

Consider functions f and g below.
Scrat [10]
Answer: -12 x^2 - 3x + 27  

In this question, there are two function of f(x) and g(x) 
f(x)= -9 x^2 - 7x + 12
g(x)= 3x^2 -4x -15
The question is about f(x)- g(x). To answer this, you just need to replace the question with the function. Don't forget to apply the minus to all the product inside the function. The calculation would be:

f(x)- g(x)= 
(-9 x^2 - 7x + 12) -(3x^2 -4x -15)=
-9 x^2 - 7x + 12 (-3x^2 +4x +15)= 
-12 x^2 - 3x + 27
