8 0

Answer:

40 or 80%

Step-by-step explanation:

50 points / 2 points per questions = 25 questions

25 questions - 5 wrong answered questions = 20 right answered questions

20 right answered questions x 2 points each = 40 points in total

Function g is a transformation of function f.
bulgar [2K]

The equation of function g(x) in terms of f(x) is g(x) = -3[f(x)].

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given:

genera form of an exponential function is  y=aeᵇˣ

Now, equation for f(x) is

f(x) = e^{(log \;2)x} -2

Similarly, graph for g(x) is

g(x) = -3e^{(log \;2)x} +6

Comparing the two function a relation can  be establish

g(x) = -3[f(x)]

Suppose John is a high school statistics teacher who believes that watching many hours of TV leads to lower test scores. Immedia
Hatshy [7]

This question is incomplete, the complete question is;

Suppose John is a high school statistics teacher who believes that watching many hours of TV leads to lower test scores. Immediately after giving the most recent test, he surveyed each of the 24 students in his class and asked them how many hours of TV they watched that week. He then matched each student's test grade with his or her survey response. After compiling the data, he used hours of TV watched to predict each student's test score. He found the least-squares regression line to be y"  = -1.5x + 85.

He also calculated that the value of r, the correlation, was -0.61.

what is the correct value of the coefficient of determination R² and give a correct interpretation of its meaning

Answer:

Interpretation of coefficient of determination R² = 0.3721

R² = 0.3721, meaning 37.21% of the total variation in test scores can be explained by the least square regression line

Step-by-step explanation:  

Given the data in the question;

the least square regression line is;

y"  = -1.5x + 85

the correlation coefficient r = -0.61

Now, the coefficient of determination R² is square of correlation coefficient r

R² = -61²

R² = 0.3721

Line m intersects the x-axis. Line n is parallel to line m. Which statement MUST be correct about line n? A) It intersects the x
Shalnov [3]

Answer:

Choice C --- It intersects the x-axis at the same angle as line m

Step-by-step explanation:

Check out the attached image below for an example. In this example, both lines form a 30 degree angle with the x-axis. These two angles are congruent due to the corresponding angle theorem. This is the idea where two parallel lines form congruent angles such that they are in the same corresponding position.
