Find the coordinates of the midpoint of segment XY for X(-2, 3) and Y(-8, -9).

(PLEASE SOLVE ASAP!!) Suppose the entry fee to Arches national park is $25 per vehicle. Suppose the entrance fee to Bryce nation

GarryVolchara [31]

Answer:

Bryce national park has the greatest cost per vehicle.

Step-by-step explanation:

From the question, we are given the following:

For Arches national park

Cost per vehicle or entry fee per vehicle at Arches national park = $25

For Bryce national park

We have:

y = 30x ........................... (1)

y = the total cost in dollars

x = the number of vehicles

To obtain the cost per vehicle at Bryce national park, we have to assume that the number of vehicles is one by setting x equal to one, that is, x = 1.

Substituting x = 1 into equation (1), we have:

y = 30 * 1 = 30

This implies that cost per vehicle at Bryce national park is $30.

Conclusion

Since the $30 cost per vehicle at Bryce national park is greater than the $25 cost per vehicle at Arches national park, it therefore implies that Bryce national park has the greatest cost per vehicle.

What is the sum and product to this quadratic equation. x^2+7x+2=0

Pani-rosa [81]

I don't know specifically what the sum and product of an equation is but

factor using quadratic formula

if you have an equation in ax^2+bx+c=0 then you can solve for x using

$x= \frac{-b+ \sqrt{b^2-4ac} }{2a}$ or $x= \frac{-b- \sqrt{b^2-4ac} }{2a}$

so input
a=1
b=7
c=2

$x= \frac{-7+ \sqrt{7^2-4(1)(2)} }{2(1)}$
$x= \frac{-7+ \sqrt{49-8} }{2}$
$x= \frac{-7+ \sqrt{41} }{2}$ =aprox -0.2984378812836

$x= \frac{-7- \sqrt{7^2-4(1)(2)} }{2(1)}$
$x= \frac{-7- \sqrt{49-8} }{2}$
$x= \frac{-7 \sqrt{41} }{2}$ =aprox -6.7015621187165

HELP HELP HELPH EPLHEPLHEPLHEPLHEPLEP

Answers:

1a) y=-10/3x+90

1b) 20

1c) -18

2a) 2.8

2b) How much the heights of five basketball players vary from the average height.

----------------------------------------------------------------------------------------------------------------

Explanations:

1a) The trend line is linear, so we just need to find the slope and y-intercept to find an equation for it. Our y-intercept is (0,90), or 90, and our slope is -10/3. Our equation is now y=-10/3x+90.

1b) To find when x=21, we plug 21 into our equation where the x is. Now we do the math.

y=-10/3(21)+90 (plug in)

y=-70+90 (simplify by multiplying -10/3 by 21)

y=20 (simplify by adding -70 to 90)

Therefore, we can predict that when x is 21, y is 20.

1c) To find when y=150, we plug 150 into our equation where the y is. Now we do some more math.

150=-10/3x+90 (plug in)

60=-10/3x (subtract 90 from both sides

-18=x (divide both sides by -10/3)

Therefore, we can predict that when y is 150, x is -18.

----------------------------------------------------------------------------------------------------------------

2a) The mean absolute deviation (or MAD for short) of a data set is calculated as such:

Step 1) Find the mean (average) by finding the sum of the data values, then dividing the sum of the data values by the number of data values. In this case, we have the numbers 65, 58, 64, 61, and 67, which add up to 315. The data set has 5 numbers, so we divide our sum of 315 by 5 to get 63. Therefore, our mean is 63.

Step 2) Find the absolute value of the distance between each data value and the mean. In this case, we find out how far away each data value is from 63, our mean. To do this, we subtract 63 from each number.

65-63=2

58-63=-5

64-63=1

61-63=-2

67-63=4

Some of these values are negative, but we're using absolute value so they all become positive. We now have a new set of values: 2, 5, 1, 2, and 4.

Step 3) Finally, we calculate the mean of our new set of values. In this case, we will add up 2, 5, 1, 2, and 4 to get 14 and divide by 5 to get our MAD of 2.8. Therefore, the MAD (and the answer to problem 2a) is 2.8.

2b) Now we just find out what the MAD means in this context. The MAD always is a measure of variance in a data set. In this context, it's describing how much the heights (in inches) of five people on a basketball team vary from the average height.

Hope this helps!
