The weights of college football players are normally distributed with a mean of 200 pounds and a standard deviation of 50 pounds

belka [17]

Answer:

$P(170$

And we can find this probability with this difference:

$P(-0.6$

Step-by-step explanation:

Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:

$X \sim N(200,50)$

Where $\mu=200$ and $\sigma=50$

We want to find the following probability:

$P(170$

And we can use the z score formula given by:

$z=\frac{x-\mu}{\sigma}$

And using this formula we got:

$P(170$

And we can find this probability with this difference:

$P(-0.6$

Plz help this is due in 1 hour. 56a = 7/4. What is a?

elena-s [515]

To get a you have to have a on its own side
56a=7/4
divide 56 on both sides
a=56/1 divided by 4/7 (switch 7/4 to 4/7 because you are going from division to multiplication)
a=32
Hope this helped
