Answer:

It already is in standard form

Step-by-step explanation:

the answer to that equation is 2 which means it's between 1 and 10. therefore it's already in standard form or "scientific notation"

Dean Halverson recently read that full-time college students study 20 hours each week. She decides to do a study at her universi

romanna [79]

Answer: The p-value is 0.154.

Step-by-step explanation:

Since we have given that

We claim that

Null hypothesis :

$H_0:\mu=20$

Alternate hypothesis :

$H_1:\mu$

Population mean = 20 hours

Sample mean = 18.5 hours

Sample standard deviation = 4.3 hours

Sample size n = 35

So, test statistic would be

$z=\dfrac{\bar{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\z=\dfrac{18.5-20}{\dfrac{4.3}{\sqrt{35}}}\\\\z=\dfrac{-1.5}{0.726}\\\\z=-2.066$

So, the p value would be 0.154.

Hence, the p-value is 0.154.

Stephen kicked a ball inside. The equation that represents the height h in feet of the ball after being kicked and elapsed amoun

kodGreya [7K]

Answer:

The maximum height of the ball is: 14.0625ft

Step-by-step explanation:

The missing information is:

$h(t) = 30t - 16t^2$

Required

The maximum height the ball attained

First, we calculate the time to reach the maximum height.

For a function: $h(t) = at^2 + bt + c$

The maximum is: $t = \frac{-b}{2a}$

So, the maximum of $h(t) = 30t - 16t^2$ is:

$t = \frac{-b}{2a}$

Where

$a = -16; b = 30$

So:

$t = -\frac{30}{2*-16}$

$t = -\frac{30}{-32}$

$t = \frac{30}{32}$

$t = 0.9375$

The maximum height is then calculated as:

$h(t) = 30t - 16t^2$

$h(0.9375) = 30 * 0.9375- 16 * 0.9375^2$

$h(0.9375) = 28.125- 14.0625$

$h(0.9375) = 14.0625$
