What is the answer to this problem

Andrew [12]

Answer:

1. 1 13/24

2. 5/12

Step-by-step explanation:

2/3 = 16/24

7/8 = 21/24

Add.

16/24 + 21/24 = 37/24

As a mixed number, this is 1 13/24.

3/4 = 9/12

1/3 = 4/12

Subtract.

9/12 - 4/12 = 5/12

Hope this helps!

Write your answer in the form y=my+b

CaHeK987 [17]

Answer:

y= -2x+18

Step-by-step explanation:

1. The secant line is a line that passes through 2 points in the function.

2. Determine the y values for x=-6 and x=3 by plugging the x values into the x^2 + x function. This yields 30 for x=-6 and 12 for x=3.

3. Find the slope by calculating the rise over the run, represented by the equation (y2 - y1)/(x2-x1). Plugging in the numbers we get (12-30) divided by (3 -(-6)). This gives you a slope equation of -18/9 (subtracting a negative yields a positive), which simplifies to -2.

4. Now that you have your slope m, apply it backwards from x=3 (x=2 yields 14 for y, 1 yields 16, 0 yields 18). Once you arrive at x=0, the y value is your y-intercept.

5. Put the y-intercept b into the equation y= mx+b, and you come out with y= -2x + 18!

Which of the following is a Type I error?

Sedaia [141]

Answer:

C. The president rejects the hypothesis that the proportion of students who earn a bachelor's degree within six years is 0.398, when, in fact, the proportion is 0.398.

Step-by-step explanation:

A type I error occurs if you reject the null hypothesis when it is true.

Now the hypotheses are:

$H_0:$ The proportion is 0.398

$H_1:$ The proportion is less than 0.398

If in actual fact the proportion is 0.398, then the president must not reject the $H_0$ .

This is a correct decision.

If in actual fact the proportion is 0.398, and the president rejects the $H_0$ , then a type I error is committed.

The correct choice is C.
