Let's solve your inequality step-by-step.
−7n + 6 ≥ − 43

Step 1: Subtract 6 from both sides.
−7n + 6 − 6 ≥ −43 − 6 − 7n ≥ −49

Step 2: Divide both sides by -7.
−7n − 7 ≥ −49 − 7n ≤ 7

So, true

Kobotan [32]

Answer:

2.56 gallons per minute!

Step-by-step explanation:

44.8 gallons - 32 gallons = 12.8 gallons

12.8 gallons in 5 minutes - so we need to find the unit rate (per one minute)

12.8/5 = 2.56

2.56 gallons per minute!

Suppose you randomly guess on every question of a 20 question True/False test. Let x = number of questions that you answer corre
castortr0y [4]

Answer:

18.14% probability that you would get at least 12 questions correct.

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 = 10, \sigma = 2.2

What is the probability that you would get at least 12 questions correct?

This is 1 subtracted by the pvalue of Z when X = 12. So

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

Z = \frac{12 - 10}{2.2}

Z = 0.91

Z = 0.91 has a pvalue of 0.8186.

So there is a 1-0.8186 = 0.1814 = 18.14% probability that you would get at least 12 questions correct.
