**CORRECTION** 21/2 because when you simplify it (dividing the top and the bottom by 2) you get 21/2. My first asnwer was a mixed number

To figure this out, we need to look for how many times 4 can go into 42.

4*10=40

Later, we have a remainder of 2 because 42-40=2

We write 10 as the whole number and 2 on the numerator.

10 2/4 = 10 1/2

Final answer: 10 1/2 is the mixed number, but the improper fraction simplified is 21/2 

Improper fraction: 21/2
Mixed number: 10 1/2

Answer:

120 m^2

Step-by-step explanation:

6*2=12 for each narrow piece of the rectangular prism and since there are four multiply 12 times 4. Use the equation 6*6=36 for each of the larger sides and multiply 36 by 2 because there are only two large sides.

Suppose Q and R are independent events. Find P(Q and R) if P(Q) =4/5 and P(R) =4/11
9966 [12]
Since Q and R are independent, this means P(Q and R) = P(Q)*P(R)

<span>P(Q and R) = P(Q)*P(R)
</span><span>P(Q and R) = (4/5)*(4/11)
</span><span>P(Q and R) = (4*4)/(5*11)
</span>P(Q and R) = 16/55

andrey2020 [161]

Answer:

0.0174 = 1.74% probability that the sample mean would be greater than 101.63 WPM

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

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.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}};

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

\mu = 97, \sigma = 19, n = 75, s = \frac{19}{\sqrt{75}} = 2.1939

What is the probability that the sample mean would be greater than 101.63 WPM?

This is 1 subtracted by the pvalue of Z when X = 101.63. So

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

By the Central Limit Theorem

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

Z = \frac{101.63 - 97}{2.1939}

Z = 2.11

Z = 2.11 has a pvalue of 0.9826.

1 - 0.9826 = 0.0174

0.0174 = 1.74% probability that the sample mean would be greater than 101.63 WPM
