Answer:

The researchers think that 65% of college students will graduate with debt when, in fact, more or less than 65% of college students will graduate with debt.

Step-by-step explanation:

A Type II error is the decision not to reject the null hypothesis when, in fact, it is false. In this case, the Type II error is when the researchers think that 65% of college students will graduate with debt when, in fact, more or less than 65% will graduate with debt.

<h2>Answer with explanation:</h2>

We know that in statistics, the Type II error happens when the null hypothesis is false but fails to get rejected.

Given : The null hypothesis, H_0, is: researchers claim that 65% of college students will graduate with debt.

Then , Type II error in this scenario will be when the researcher claim 65% of college students will graduate with debt is false but fails to be rejected.

The steps for deriving the Quadratic Formula are shown. Which reason is incorrect?
mezya [45]
Hi, Hagrid :) Thanks for posting your question here at Brainly. I hope I could help you with this problem.

The incorrect reason would be letter A: add c/a to both sides. 
What he did was transpose the term c/a from the left to the right so that he could separate the terms with variables to the left hand side and the constants in the right hand side.

Twice the difference of a number and 3 equals 2 use the variable c for the unknown number.
Lesechka [4]

The number is 4

Step-by-step explanation:

First of all we have to convert the given statement in mathematical form.

Let c be the number then according to given statement

2(c-3) = 2

We have to isolate the variable in the equation

Dividing both sides by 2

\frac{2(c-3)}{2} = \frac{2}{2}\\c-3 = 1

Adding 3 on both sides

c-3+3 = 1+3\\c = 4

Hence,

The number is 4

Write an equation of the line that passes through (1,2) and is perpendicular to the line y= 1/3x+4
zvonat [6]

Slope-intercept form:  y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

For lines to be perpendicular, their slopes have to be the negative reciprocal of each other. (Basically flip the sign +/- and the fraction(switch the numerator and the denominator))

For example:

Slope = 2 or \frac{2}{1}

Perpendicular line's slope = -\frac{1}{2}   (flip the sign from + to -, and flip the fraction)

Slope = -\frac{3}{4}

Perpendicular line's slope = \frac{4}{3}  (flip the sign from - to +, and flip the fraction)

y = 1/3x + 4        The slope is 1/3, so the perpendicular line's slope is -\frac{3}{1} or -3.

Now that you know the slope, substitute/plug it into the equation:

y = mx + b

y = -3x + b       To find b, plug in the point (1, 2) into the equation, then isolate/get the variable "b" by itself

2= -3(1) + b     Add 3 on both sides to get "b" by itself

2 + 3 = -3 + 3 + b

5 = b

y = -3x + 5

What are the values of x and y?
Talja [164]
Hello!

All the angles inside a triangle is equal to 180

To find x you can do

180 - 50 - 70 = 60

x = 60

To find y you have to find the other missing angle in the other triangle

180 - 50 - 60 = 70

A line is equal to 180°


To find y you do 

180 - 60 - 70 = 50

x = 60 and y = 50

Hope this helps!
