6. Often, judging the symmetry and skewness of such distributions is not easy to do by eye, especially when they are asymmetrical or skewed in different ways. Here, the mean of set A is about 7, so the data is skewed to the left more than for set B, which has a mean of about 5.4--closer to the middle of the range.

Both data sets have the same range: 2–10. Set A's mode of 8 is higher than set B's mode of 6.

Hence, the only true statement appears to be

... B. Set B has the lesser mean.

Answer:

1,518,000 committees.

Step-by-step explanation:

We have been given that the judiciary committee at a college is made up of three faculty members and four students. Ten faculty members and 25 students have been nominated for the committee.

We will use combinations for solve our given problem.

$^nC_r=\frac{n!}{r!(n-r)!}$ , where,

n = Number of total items,

r = Items being chosen at a time.

$^{10}C_3\cdot ^{25}C_4=\frac{10!}{3!(10-3)!}\cdot \frac{25!}{4!(25-4)!}$

$^{10}C_3\cdot ^{25}C_4=\frac{10!}{3!*7!}\cdot \frac{25!}{4!*21!}$

$^{10}C_3\cdot ^{25}C_4=\frac{10*9*8*7!}{3*2*1*7!}\cdot \frac{25*24*23*22*21!}{4*3*2*1*21!}$

$^{10}C_3\cdot ^{25}C_4=10*3*4\cdot 25*23*22$

$^{10}C_3\cdot ^{25}C_4=120\cdot 12650$

$^{10}C_3\cdot ^{25}C_4=1,518,000$

Therefore, 1,518,000 judiciary committees could be formed at this point.

A clock is constructed using a regular polygon with 60 sides. The polygon rotates every minute. How much has the polygon

beks73 [17]

In 7 minutes, the clock has rotated 42 degrees

<u>Solution:</u>

Given, A clock is constructed using a regular polygon with 60 sides.

The polygon rotates every minute.

As there will be 60 minutes in clock, and this clock has 60 sides, each minute represents a side.

Now we know that, in a clock, 1 hour = 60 minutes

60 minutes = 360 degrees

Then, 7 minutes = “n” degrees

So, by criss cross multiplication,

$\begin{array}{l}{n \times 60=360 \times 7} \\\\ {\rightarrow n=6 \times 7} \\\\ {\rightarrow n=42}\end{array}$

Hence, in 7 minutes, the clock has rotated 42 degrees
