professor190 [17]

Answer:

Mean speed = 41.3 mph

Step-by-step explanation:

Given that,

The speeds of an automobiles are given below:

20, 35, 42, 52, 65, 49, 24, 37, 23, 41, 50, 58

We need to find the mean speed of the cars.

Mean = sum of observations/ no. of observation

$M=\dfrac{20+35+42+52+65+49+24+37+23+41+50+58}{12}\\\\M=41.3$

So, the mean speed of the cars is equal to 41.3 mph.

Issac tosses a quarter off of a bridge, creating the shape of a parabola. The parabola can be represented by the equation h=-16t

Wittaler [7]

Answer:

c) 18 units

d) 1 second

Step-by-step explanation:

h = -16t² - 4t + 20

c) t = 0.25

h = -16(0.25)² - 4(0.25) + 20

h = 18

d) -16t² - 4t + 20 = 0

4t² + t - 5 = 0

4t² + 5t - 4t - 5 = 0

t(4t + 5) - (4t + 5) = 9

(4t + 5)(t - 1) = 0

t = -1.25, 1

t = 1 second
