<em>∙•❁ </em>Okay time to solve this Step-By-Step.<em>❁•∙ </em>

16−<span>2n</span>−5+<span>8n</span>=<span>65

<em>∙•❁ </em>So the first part we need to Simplify both sides of this equation, so:

<span><span><span><span>16−<span>2n</span></span>−5</span>+<span>8n</span></span>=65

<em>∙•❁ </em>We are going to simplify this Step-By-Step.

<span><span><span><span>16−<span>2n</span></span>−5</span>+<span>8n</span></span>=65

</span><span><span><span><span><span><span>16+</span>−<span>2n</span></span>+</span>−5</span>+<span>8n</span></span>=65

<em>∙•❁ </em>Combine like terms:
</span><span><span><span><span>
(<span><span>−2n</span>+8n</span>)</span>+<span>(<span>16+−5</span>)</span></span>=65 </span>

<span><span>6n+11</span>=65

</span><span><span><span>6n</span>+11</span>=65

<em>∙•❁ </em>Now subtract 11 from both sides.

<span><span><span><span>6n</span>+11</span>−11</span>=<span>65−11

</span></span><span><span>6n</span>=54

<em>∙•❁ </em>Now divide both sides by 6 and you'll get your answer:

6n/6=54/6

<em>∙•❁ </em>Your final answer is:

n=9

<em>∙•❁I hope this helps!❁•∙ </em> </span></span></span></span></span>

At a Psychology final exam, the scores are normally distributed with a mean 73 points and a standard deviation of 10.6 points. T
USPshnik [31]

Answer:

The score that separates the lower 5% of the class from the rest of the class is 55.6.

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 question:

\mu = 73, \sigma = 10.6

Find the score that separates the lower 5% of the class from the rest of the class.

This score is the 5th percentile, which is X when Z has a pvalue of 0.05. So it is X when Z = -1.645.

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

-1.645 = \frac{X - 73}{10.6}

X - 73 = -1.645*10.6

X = 55.6

The score that separates the lower 5% of the class from the rest of the class is 55.6.

At an art exhibition there are 12 paintings of which 10 are original. A visitor selects a painting at random and before decides
Reika [66]

Answer:

a) 0.8333

b) 0.75

c) 0.8181 or 0.9090

Step-by-step explanation:

a)

The probability the visitor selects an authentic painting is  

10/12 = 0.8333

b)

Since the opinion of the expert does not depend on your choice, the events are <em>independent</em>, so the probability that the expert says is authentic and it really is, is

0.8333*0.9 = 0.75

c)

If the expert decides the painting is a copy and it is not, then there are 11 paintings of which 9 are authentic, so the probability the visitor selects a new original painting is

9/11= 0.8181

If the expert decides the painting is a copy and it is, then there are 11 paintings of which 10 are authentic, so the probability the visitor selects a new original painting is

10/11= 0.9090
