Answer:

The maximum height of the volleyball is 12.25 feet.

Step-by-step explanation:

The height of the volleyball, h(t), is modeled by this equation, where t represents the  time, in seconds, after that ball was set :

h(t)=-16t^2+20t+6 ....(1)

The volleyball reaches its maximum height after 0.625 seconds.

For maximum height,

Put \dfrac{dh}{dt}=0

Now put t = 0.625 in equation (1)

h(t)=-16(0.625)^2+20(0.625)+6\\\\h(t)=12.25\ \text{feet}

So, the maximum height of the volleyball is 12.25 feet.

Rolling a six-sided die 74 times and recording the number of odd numbers rolled.
Ber [7]

Answer:

Binomial

Step-by-step explanation:

Given that a six sided die is rolled 74 times.

When a fair die is rolled number of outcomes are 6 out of which 3 are odd and 3 even.

Pro (getting odd) = Prob (getting even) = 0.5

Also each throw is independent of the other

Hence X - no of throws which resulted in odd numbers is Binomial with

n = 74 and p = 0.5

Mean = 37 and variance = 18.5

(all conditions for binomial are met)

(There are two outcomes either odd or even and each trial is independent of the other)
