What are the zeros of the function f(x) = x2 + 8x + 4, expressed in simplest radical form?
Katyanochek1 [597]

Answer:

Step-by-step explanation:

assuming it is x^{2} +8x+4

Using Quadratic formular -

a - 1

b - 8

c - 4

x= \frac{ -8 -,+ \sqrt{(8^2) - 4 (1)(4)}}{2(1)} \\\\

x = \frac{-8 +,- \sqrt{48} }{2}\\\\

x = \frac{-8+,- 4\sqrt{3} }{2}

x = {-4+,- 2\sqrt{3} }

What is the inverse of the function f(x) = 3x – 2?<br> f-1(x) =
Eddi Din [679]

Answer:

\frac{x + 2}{3}

Step-by-step explanation:

Replace y with f(x).

y = 3x - 2

Swap x and y and solve for y

x = 3y - 2

x + 2 = 3y

\frac{x + 2}{3}  = y

Assume that the empirical rule is a good model for the time it takes for all passengers to board an airplane. The mean time is 4
slamgirl [31]

Answer:

The interval that describes how long it takes for passengers to board the middle 95% of the time is between 40.16 minutes and 55.84 minutes.

Step-by-step explanation:

Problems of normally distributed samples can be 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 = 48, \sigma = 4.

Which interval describes how long it takes for passengers to board the middle 95% of the time?

This is between the 2.5th percentile and the 97.5th percentile.

So this interval is the value of X when Z has a a pvalue of 0.025 and the value of X when Z has a pvalue of 0.975

Lower Limit

Z has a pvalue of 0.025 when Z = -1.96. So

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

-1.96 = \frac{X - 48}{4}

X - 48 = -1.96*4

X = 40.16

Upper Limit

Z has a pvalue of 0.975 when Z = 1.96. So

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

1.96 = \frac{X - 48}{4}

X - 48 = 1.96*4

X = 55.84

The interval that describes how long it takes for passengers to board the middle 95% of the time is between 40.16 minutes and 55.84 minutes.
