Answer:

y = 13/7x - 13

Step-by-step explanation:

We are given the x-intercept of (7, 0) and the y-intercept of (0, -13). We can solve for the slope using the formula [ y2-y1/x2-x1 ] and the points given.

-13-0/0-7

-13/-7

13/7

We can write the equation in slope-intercept form which is [ y = mx + b ] where m = slope and b = y-intercept. We are already solved for the slope and was given the y-intercept so we can fill it into the formula.

y = 13/7x - 13

Best of Luck!

Vesna [10]

Average speed = (distance covered) / (time to cover the distance)

   = (500 miles) / (6.7 hours)

   = (500 / 6.7) (mile/hour)

   = 74.63 miles per hour.

I imagine there were quite a number of pit stops included in that.

This is faster than I expected when I first read your question.
That's really gettin' with it for cars in 1911 !

What is g(x)?

Vera_Pavlovna [14]

Step-by-step explanation:

This has a U like shape so it a parabola.

Parabola correlate with quadratic functions

$y = {ax}^{2} + bx + c$

Since it Going down, the answer is C -x^2.

Answer:

$7-3.182 \frac{13.638}{\sqrt{4}}= -14.698$

$7+3.182 \frac{13.638}{\sqrt{4}}= 28.698$

Step-by-step explanation:

For this case we have the following info given:

Weight before diet 180 125 240 150

Weight after diet 170 130 215 152

We define the random variable $D = before-after$ and we can calculate the inidividual values:

D: 10, -5, 25, -2

And we can calculate the mean with this formula:

$\bar X= \frac{\sum_{i=1}^n X_i}{n}$

And the deviation with:

$s= \sqrt{\frac{\sum_{i=1}^n (X_i- \bar X)^2}{n-1}}$

And after replace we got:

$\bar D= 7, s_d = 13.638$

And the confidence interval for this case would be given by:

$\bar D \pm t_{\alpha/2} \frac{s_d}{\sqrt{n}}$

The degrees of freedom are given by:

$df = n-1= 4-1=3$

For the 95% of confidence the value for the significance is $\alpha=0.05$ and the critical value would be $t_{\alpha/2}= 3.182$ . And replacing we got:

$7-3.182 \frac{13.638}{\sqrt{4}}= -14.698$

$7+3.182 \frac{13.638}{\sqrt{4}}= 28.698$
