The answer is -7/6

first use the slope formula( y1-y2/x1-x2) to set up the equation. the y values on top, x value on bottom. and always subtract.
-6-1/ 4–2
then combine the numbers in the numerator together and the numbers in the denominator together. in this case you have two negatives between the 4 and the 2 so it becomes a plus sign
-7/4+2
-7/6
and then you have ur answer.

What equation represents the line that passes through the points (-3 7 and (3 3?

dexar [7]

Hello : let A(-3,7) B(3,3)
the slope is : (YB - YA)/(XB -XA)
(3-7)/(3+3) = -2/3
an equation is : y=ax+b a is a slope

y = (-2/3)x +b

the line through point B (3,3) : 3 = (-2/3)(3)+b
b =5
the equation is : y =(-2/3)x+5

If Joseph buys a T.V. At 35% off and it’s original costs $599.99 how much did he pay for the tv?

Monica [59]

Answer: He paid $\$389.9935$ for the T.V.

Step-by-step explanation:

We need to analize the information provided:

- The original cost of the T.V. was $599.99

- Joseph buys it at 35% off the original cost.

Let be "x" the amount Joseph paid for the T.V.

We can calculate "x" with the following expression:

$x=\$599.99-(\$599.99)(0.35)\\\\x=\$389.9935$

Therefore, he paid $\$389.9935$ for the T.V.

Graph this piecewise function:

Pepsi [2]

Consider the function f(x) = 2 x + 1. We recognize the equation y = 2 x + 1 as the Slope-Intercept form of the equation of a line with slope 2 and y-intercept (0,1). Think of a point moving on the graph of f. As the point moves toward the right it rises.

US average math SAT scores follow a normal distribution with a mean of 505 and a standard deviation of 112. A sample of 64 enter

Hitman42 [59]

Answer:

The claim that the scores of UT students are less than the US average is wrong

Step-by-step explanation:

Given : Sample size = 64

Standard deviation = 112

Mean = 505

Average score = 477

To Find : Test the claim that the scores of UT students are less than the US average at the 0.05 level of significance.

Solution:

Sample size = 64

n > 30

So we will use z test

$H_0:\mu \geq 477\\H_a:\mu < 477$

Formula : $z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

$z=\frac{505-477}{\frac{112}{\sqrt{64}}}$

$z=2$

Refer the z table for p value

p value = 0.9772

α=0.05

p value > α

So, we accept the null hypothesis

Hence The claim that the scores of UT students are less than the US average is wrong
