(05.02 MC) The figure below shows a line graph and two shaded triangles that are similar: A line is shown on a coordinate grid.

The x-axis values are from negative 10 to positive 10 in increments of 2 for each grid line. The y-axis values are from negative 5 to positive 5 in increments of 1 for each grid line. The line passes through the ordered pairs negative 8, 4, and 0, 0, and 8, negative 4. A shaded right triangle is formed so that its hypotenuse is from ordered pair 0, 0 labeled as O to negative 4, 2 labeled as A, one leg is from 0, 0 to negative 4, 0, and the second leg is from negative 4, 0 to negative 4, 2. Another shaded right triangle is formed with the hypotenuse from negative 4, 2 to negative 6, 3, labeled as B, one leg is from negative 4, 2 to negative 6, 2, and the second leg is between negative 6, 2 to negative 6, 3. Which statement about the slope of the line is true? It is −2 throughout the line. It is fraction negative 1 over 2 throughout the line. The slope from point O to point A is fraction 1 over 2 times the slope of the line from point A to point B. The slope from point O to point A is two times the slope of the line from point A to point B.

"How much do students pay, on average, for textbooks during the first semester in college? From a random sample of 400 students
dezoksy [38]

Answer: The margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.

Step-by-step explanation:

Since we have given that

Sample size = 400

Mean = $357.75

Standard deviation = $37.89

At 95% confidence level, z = 1.96

We first find the margin of error.

Margin of error is given by

z\times \dfrac{\sigma}{\sqrt{n}}\\\\=1.96\times \dfrac{37.89}{\sqrt{400}}\\\\=3.71

95% confidence interval would be

\bar{x}\pm \text{margin of error}\\\\=357.75\pm 3.71\\\\=(357.75-3.71,357.75+3.71)\\\\=(354.04,361.46)

Hence, the margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.

3x+3y=6 and 5x-6y=15
Anna71 [15]
Multiply first equaton by 2 and add to the other equation

6x+6y=12
<u>5x-6y=15 +</u>
11x+0y=27

11x=27
divide both sides by 11
x=27/11


sub back
3x+3y=6
divide both sides by 3
x+y=2
(27/11)+y=2
2 and 5/11+y=2
minus  2 and 5/11 both sides
y=-5/11

x=27/11
y=-5/11
(27/11,-5/11)
