Answer:

im Pretty sure x

Step-by-step explanation: Distribute:

=4x2+−12x+9+−9x2+12x+−4

Combine Like Terms:

=4x2+−12x+9+−9x2+12x+−4

=(4x2+−9x2)+(−12x+12x)+(9+−4)

=−5x2+5

Answer:  −5x2+5

Suppose a certain species of fawns between 1 and 5 months old have a body weight that is approximately normally distributed with
Crank

Answer:

P(X

And the best way to solve this problem is using the normal standard distribution and the z score given by:

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

If we apply this formula to our probability we got this:

P(X

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

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(26,4.2)  

Where \mu=26 and \sigma=4.2

We are interested on this probability

P(X

And the best way to solve this problem is using the normal standard distribution and the z score given by:

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

If we apply this formula to our probability we got this:

P(X
