Roughly 75% of students take the bus to school. If you were to ask 9 students in your class, what is the probability that at mos
GREYUIT [131]

The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%

<h3>How to find the probability?</h3>

We know that roughly 75% of the students take the bus, then, if we select a student at random.

  • There is a probability of 0.75 that the student takes the bus.
  • There is a probability of 0.25 that the student does not take the bus.

The probability that at most 8 out of 9 students take the bus, is equal to one minus the probability of the 9 taking the bus, which is:

p = (0.75)^9 = 0.075

Then we have:

P = 1 - 0.075 = 0.925

The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%

Suppose speeds of vehicles traveling on a highway have an unknown distribution with mean 63 and standard deviation 4 miles per h
Mashutka [201]

Answer:

The standard deviation for the sample mean distribution=0.603

Step-by-step explanation:

We are given that

Mean,\mu=63

Standard deviation,\sigma=4

n=44

We have to find the standard deviation for the sample mean distribution using  Central Limit Theorem for Means.

Standard deviation for the sample mean distribution

\sigma_x=\frac{\sigma}{\sqrt{n}}

Using the formula

\sigma_x=\frac{4}{\sqrt{44}}

\sigma_x=\frac{4}{\sqrt{2\times 2\times 11}}

\sigma_x=\frac{4}{2\sqrt{11}}

\sigma_x=\frac{2}{\sqrt{11}}

\sigma_x=0.603

Hence, the standard deviation for the sample mean distribution=0.603

2. The equation h(t)=−16t2+19t+110 gives the height of a rock, in feet, t seconds after it is thrown from a cliff.
Paul [167]
For this case we have an equation of the form:
 h (t) = - (1/2) * a * t ^ 2 + vo * t + h0
 Where,
 vo: initial speed
 a: acceleration:
 h0: initial height.
 We have the following equation:
 h (t) = - 16t2 + 19t + 110
 Therefore, the initial velocity is:
 vo = 19 feet / s
 Answer:
 
The initial velocity when the rock is thrown:
 
vo = 19 feet / s
