I need this answerd ASAP ill give brainliest to whoever solves it first along with 3<br>40 points​
Gwar [14]

Answer:

Below.

Step-by-step explanation:

Mean = (61+59+60+50+54+56+61+63)/8

= 464/8

= 58 degrees

Deviations:

61 - 58 = 3

59-58 = 1

60-58 = 2

50-58 = -8 = 8   (absolute value)

54-58= -4 = 4

56-58 = -2 = 2

61-58 = 3

63-58 = 6

MAD = (3+1+2+8+4+2+3+6) / 8

= 3.625

= 3.6 to the nearest tenth.

The height of a ball in meters is modeled by f(x) equals negative 5X squared +50 X where X is the time in seconds after it is hi
luda_lava [24]

Answer:

10 seconds

Step-by-step explanation:

Find the zeros by equating f(x) to zero, that is

- 5x² + 50x = 0 ← factor out - 5x from each term

- 5x(x - 10) = 0

Equate each factor to zero and solve for x

- 5x = 0 ⇒ x = 0

x - 10 = 0 ⇒ x = 10

x = 0 denotes the time when the ball is struck and x = 10 when the ball returns to the ground.

Time in air = 10 - 0 = 10 seconds
