The number of books borrowed from a library each week follows a normal distribution. When a sample is taken for several weeks, t
Marat540 [252]
\mathbb P(X>250)=\mathbb P\left(\dfrac{X-190}{30}>\dfrac{250-190}{30}\right)=\mathbb P(Z>2)\approx0.0228

Or, if you're familiar with the empirical rule and the basic properties of the normal distribution, you can use the fact that approximately 95/% of the distribution lies within two standard deviations of the mean, or

\mathbb P(|Z|

which means about 5\% of the distribution lies outside this interval, or

\mathbb P((-22))\approx0.05

Because the distribution is symmetric, you have

\mathbb P(-22)
\implies \mathbb P((-22))=\mathbb P(-22)=2\mathbb P(Z>2)\approx0.05
\implies \mathbb P(Z>2)\approx 0.025

At a amusement ,park 360 visitors rode the roller coaster in 3 hours.Write and solve a proportion to find the number of visitors
Pachacha [2.7K]
First you need to find out about how many people went on the roller coaster in one hour by doing 360 divided by 3 and you would get 120. So then you would try to find out how many people went on the coaster in 7 hours by doing 360 times 2 because 3 hours multiplied by 2 is 6 and you would do that to find out how many people went on the coaster in 6 hours, and you would get 720. Next, you have 1 more round of people, so you need to do 720 + 120 which is 840. So about 840 people rode the coaster in 7 hours. Hope this helped.

bulgar [2K]

Answer:

0

Step-by-step explanation:

f(x) = 2/5(6 - x)²

f(6) = 2/5[6 - (6)]²

f(6) = 2/5(0)²

f(6) = 0
