The factors of the trinomial to the given quadratic expression are (x+1) and (x-4)

<h3>Factoring quadratic equation</h3>

Given the quadratic equation below

f(x) = x^2 - 3x - 4

Factorize

f(x) = x^2 - 4x + x - 4 = 0
f(x) = x(x - 4) + 1(x - 4) = 0
(x+1)(x-4) = 0

Hence the factors of the trinomial to the given quadratic expression are (x+1) and (x-4)

For the most recent year available, the mean annual cost to attend a private university in the United States was $20,307. Assume
Maksim231197 [3]

Answer:

27,361.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 20307, \sigma = 4275

Ninety-five percent of all students at private universities pay less than what amount?

This is the 95th percentile, that is, X when Z has a pvalue of 0.95. So X when Z = 1.65.

Z = \frac{X - \mu}{\sigma}

1.65 = \frac{X - 20307}{4275}

X - 20307 = 1.65*4275

X = 27,361

So the answer is 27,361.

Charra [1.4K]

Answer:

A = 314 inches^2

Step-by-step explanation:

We know the diameter of the glass.  We need to find the radius

d = 2r

20 = 2r

Divide each side by 2

20/2 = 2r/2

10 =r

To find the area of the glass

A = pi r^2

A = pi * 10^2

A = pi*100

A = 100 *(3.14)

   = 314 in^2
