Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Mean score = 96

Sample size = 100

We need to find the distribution of the test scores is likely to be :

In negatively skewed, the mean is to the right side.

It also shows that the tail on the left side is longer than the tail on the right side.

And the bulk value lies in the right of the mean.

In our situation, mean is to the right side and tail is to the left side.

Hence, it is negatively skewed.

Therefore, Option 'C' is correct.

What is 859 under a thousand as a mixed number?
Semmy [17]
To convert the improper fraction \frac{1000}{859} into a mixed number, you first want to divide the numerator (1000) by the denominator (859):
1000 \div 859 = 1 R141

The quotient, which is 1, will be your whole number part of your mixed number. The remainder, 141, will become the numerator of the fraction part of your mixed number. The original denominator of your improper fraction, 859, is still the denominator of your mixed number. So your mixed number form of your improper fraction is:
\frac{1000}{859} = 1 \frac{141}{859}

Your answer is 1 \frac{141}{859}

A manufacturing plant earned $80 per man-hour of labor when it opened. Each year, the plant earns an additional 5% per man-hour.
baherus [9]

A function that gives the amount that the plant earns per man-hour t years after it opens is \mathrm{A}(\mathrm{t})=80 \times 1.05^{\mathrm{t}}

<h3><u>Solution:</u></h3>

Given that  

A manufacturing plant earned $80 per man-hour of labor when it opened.

Each year, the plant earns an additional 5% per man-hour.

Need to write a function that gives the amount A(t) that the plant earns per man-hour t years after it opens.  

Amount earned by plant when it is opened = $80 per man-hour

As it is given that each year, the plants earns an additional of 5% per man hour

So Amount earned by plant after one year = $80 + 5% of $80 = 80 ( 1 + 0.05) = (80 x 1.05)

Amount earned by plant after two years is given as:

=(80 \times 1.05)+5 \% \text { of }(80 \times 1.05)=(80 \times 1.05)(1.05)=80 \times 1.052

Similarly Amount earned by plant after three years =80 \times 1.05^{t}

\begin{array}{l}{\Rightarrow \text { Amount earned by plant after } t \text { years }=80 \times 1.05^{t}} \\\\ {\Rightarrow \text { Required function } \mathrm{A}(t)=80 \times 1.05^{t}}\end{array}

Hence a function that gives the amount that the plant earns per man-hour t years after it opens is \mathrm{A}(t)=80 \times 1.05^{t}
