Find the other end point<br> Endpoint (5,-1) Midpoint (5,10)
dusya [7]

Answer:

(5, 21)

Step-by-step explanation:

The x-coordinate of the midpoint of a segment is half of the sum of the x-coordinates of the endpoints.

The y-coordinate of the midpoint of a segment is half of the sum of the y-coordinates of the endpoints.

Let the unknown point have coordinates (x, y).

x-coordinate:

(5 + x)/2 = 5

5 + x = 10

x = 5

y-coordinate:

(-1 + y)/2 = 10

-1 + y = 20

y = 21

The other endpoint has coordinates (5, 21).

Please help out with this geometry homework I was assigned. And what formula do I use?
lozanna [386]

Answer:

V_{cone}   \approx 1,178.97 \:  {in}^{3}

Step-by-step explanation:

Diameter of cone = 16 in

Radius of cone r = 16/2 = 8 in

Height of cone h = 17.6 in

V_{cone}  =  \frac{1}{3} \pi {r}^{2}h \\  \\  V_{cone}  =  \frac{1}{3}  \times 3.14 \times  {(8)}^{2} \times 17.6 \\  \\   V_{cone}  =  \frac{1}{3}  \times 3,536.896 \\  \\  V_{cone}  =  1,178.96533 \\  \\  V_{cone}   \approx 1,178.97 \:  {in}^{3}  \\

A normal distribution curve, where x = 70 and σ = 15, was created by a teacher using her students’ grades. What information abou
alexira [117]

The <em><u>correct answer</u></em> is:

We can conclude that 68% of the scores were between 55 and 85; 95% of the scores were between 40 and 100; and 99.7% of the scores were between 25 and 100.

Explanation:

The empirical rule tells us that in a normal curve, 68% of data lie within 1 standard deviation of the mean; 95% of data lie within 2 standard deviations of the mean; and 99.7% of data lie within 3 standard deviations of the mean.

The mean is 70 and the standard deviation is 15. This means 1 standard deviation below the mean is 70-15 = 55 and one standard deviation above the mean is 70+15 = 85. 68% of data will fall between these two scores.

2 standard deviations below the mean is 70-15(2) = 40 and two standard deviations above the mean is 70+15(2) = 100. 95% of data will fall between these two scores.

3 standard deviations below the mean is 70-15(3) = 25 and three standard deviations above the mean is 70+15(3) = 115. However, a student cannot score above 100%; this means 99.7% of data fall between 25 and 100.
