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

The point slope form of the equation of the line that passes through -5,-1 and 10,-7 is y+7= -2/5(x-10). What is the standard fo
scoundrel [369]

2x + 5y = -15 is the standard form of equation

<em><u>Solution:</u></em>

Given that,

<em><u>The point slope form of the equation of the line that passes through (-5, -1) and (10, -7) is given by:</u></em>

y + 7 = \frac{-2}{5}(x-10)

We have to write the standard form of the equation

The standard form of an equation is Ax + By = C

In this kind of equation, x and y are variables and A, B, and C are integers

<em><u>Let us convert the given equation into standard form</u></em>

y + 7 = \frac{-2}{5}(x-10)\\\\\text{Simplify the right hand side of equation }\\\\y + 7 = \frac{-2x}{5}+\frac{20}{5}\\\\y + 7 = \frac{-2x +20}{5}\\\\5(y+7) = -2x + 20\\\\\text{Simplify the left hand side of equation }\\\\5y + 35 = -2x + 20\\\\\text{Move the variables to left side of equation and constants to right side }\\\\2x + 5y = 20 - 35\\\\2x + 5y = -15

Thus the standard form of equation is found
