In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, Joyce has scored 90, 93, and 85 on the first three. What range of scores on the fourth test will give Joyce a C for the semester (an average between 70 and 79, inclusive)? Assume that all test scores have a non-negative value.

Express your answer in interval notation.


HELP ASAP BRAINLEST AND THANKS

Answers

Answer:

[12,48]

Step-by-step explanation:

We will start by calculating the score she needs to get a 70 in the class

We will let x equal the fourth test

[tex]\frac{90+93+85+x}{4} =70[/tex]

This isn't hard to solve and we will do so by multiplying 4 by both sides and subtracting 268 (90+93+85)

This means that x= 12

We will then use the same formula but set it equal to 79

[tex]\frac{90+93+85+x}{4} =79[/tex]

We solve x in the exact same way and get x=48

our final answer is now [12,48]

In the figure, a∥e, m∥n, and m∠1 = 108°.

What is the m∠3?

Enter your answer in the box.

°

Lines n and m (reading from top to bottom) are parallel to each other, and lines a and e are parallel to each other. The two pairs of lines intersect each other. Lines m and n start at top left and drop to the bottom right. Lines a and e rise from left to right. Only six of the sixteen angles created are labelled. Angle one is the top angle made by lines n and a. Angle two is the bottom angle. Angle three is the bottom angle made by lines m and a. Angle four is the top angle made by lines n and e. Angle five is the left angle. Angle six is the bottom angle made by lines m and e.

What is the value of x?

Answers

Answer:

x = 30 degrees

Step-by-step explanation:

Okay so we start by noticing that the two pointed out vertices = 180 degrees. So we have the following equation.

(x + 12) + (3x + 48) = 180

If you combine them you get:

4x + 60 = 180

Subtract 60 from both sides..

4x = 120

Divide both sides by 4..

x = 30

And there's your answer!

Answers

Answer:

Equation of the straight line in point-slope form

 y -(-7) = [tex]\frac{-3}{4}[/tex](x-8)

Equation of the straight line

3x +4y +4=0

Step-by-step explanation:

Explanation:-

Given that the point ( 8,-7) and  [tex]m = \frac{-3}{4}[/tex]

Equation of the straight line passing through the point (x₁, y₁) and having slope 'm'

          y - y₁ = m (x-x₁)

        y -(-7) = [tex]\frac{-3}{4}[/tex](x-8)

       4( y+7) = -3(x-8)

       4y +28 = -3x +24

      3x +4y +28 -24 =0

      3x +4y +4=0
