A golfball is hit from ground level with an initial vertical velocity of 80 ft/s. Use the function h(t) = −16t2 + v0t + h0, wher

lana66690 [7]

Step-by-step explanation:

ball is hit from the ground level i.e h0=0

initial velocity=80

when the ball hits the ground it's height from the ground=0

substitute the data in the above function

0=-16t^2+80×t+0

t=0 is a solution but it is at the beginning of the projection

16t=80

t=5

Answer:

Hello your question has some missing information below is the missing information

Sample mean and Sample standard deviation

Bass 70.99 and 2.52

Tenor 69.41 and 2.79

answer : We will reject H0

Step-by-step explanation:

Determine whether the population mean height of bass singers > population mean height of tenor singers

n1 = 64 , n2 = 42

x1 ( mean ) = 70.99

x2( mean ) = 69.41

S1 ( std 1 ) = 2.52

S2 ( std 2 ) = 2.79

We will perform a two tailed test hence we will state the null and alternate hypothesis

H0 : μ1 > μ2

H1 : μ1 < μ2

significance level = 0.01

next calculate the test statistic

t = 2.96

attached below is the remaining part of the detailed solution

A baseball player is 6 ft tall. His collectible figurine is just 4 inches tall. What is the scale of the collectible figurine?

MArishka [77]

Answer:

The ratio would be 72:4

Step-by-step explanation:

Since the baseball player is 6 ft, and 1 ft+12 inches, then you have to multiply 12 and 6 to get 72 inches and the figurine already says its inches so there you go.
