Mathematics

charle [14.2K]3 years ago
7 0

Answer:

The answer to your question is: (1/2, 5)

Step-by-step explanation:

Parabola                     f(x) = 8x² - 8x + 7

                                     y = 8x² - 8x + 7

Vertical Parabola equation

( x - h)² = 4p (y - k)            Transform the original equation to this form

8x² - 8x       = y - 7            

8(x² - x  + (   )²)  = y - 7       Complete squares

8 (x² - x + (1/2)²) = y - 7 + 2    Simplification

8 (x² - x + 1/4) = y - 5

                                 (x - 1/2)² = 1/8 (y - 5)

Finally Vertex

                        (1/2 , 5)

An airplane travels 2748 miles in 6 hours.How far would they travel in 2 hours?
ziro4ka [17]
You can set up a proportion in order to get this answer. So if you're able to travel 2748 miles in 6 hours, then divide 2748 by 3  in order to get the distance for 2 hours. This should be equal to 916 miles in 2 hours.

Jason is the captain of his basketball team the list below shows how many points Jason scored in each of the first 10 games 18,2
Anika [276]
A. The scores in order are: 10, 12, 13, 14, 14, 16, 18, 23, 24, 26. The range is 26 - 10 = 16. The mean is the sum divided by 10, which is 17. The median is between 14 & 16, which is 15. The mode is 14, since it is repeated twice.
B. The variance is calculated by subtracting each score from the mean, squaring, and adding all such squares. Then divide by the number of terms (10) to get 27.6 Take the square root to get the standard deviation, which is 5.25.
C. This is for a population, since these are all 10 games that Jason played. (If it were a sample, we would divide by 9 only)

D. The mean of 17 is higher than the median of 15 and the mode of 14. This implies a left-skewed distribution. However, the SD of 5.25 is quite high relative to the mean of 17, so the distribution is not that clearly defined yet (more data points would make it clearer).
