I havent done this stuff but I'm assuming x has to be equal to the number its being subtracted from so that the end result would be 0.

mamaluj [8]
You write the problem as a mathematical expression
3x^2 + 30x + 75 =
Factor: 3 out of 3x^2 + 30x + 75.

3 (x2 + 10x + 25)

Factor using the perfect square rule.
And then your answer should be 3 ( x + 5) ^2

Assume the random variable X is normally distributed with meanmu equals 50μ=50and standard deviationsigma equals 7σ=7.Compute th
nekit [7.7K]

Answer:

P(35

And we can find this probability with the following difference and using the normal standard table or excel we have:

P(-2.143

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 variable of interest of a population, and for this case we know the distribution for X is given by:

X \sim N(50,7)  

Where \mu=50 and \sigma=7

We are interested on this probability

P(35

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(35

And we can find this probability with the following difference and using the normal standard table or excel we have:

P(-2.143
