9 students volunteer for a committee. How many different 7-person committees can be chosen?

1 answer:

7 0

If order doesn't matter (e.g. all the positions in the committee are essentially identical) then the number of possible choices is $\dbinom97=\dfrac{9!}{7!(9-7)!}=36$ .

Geometry question for homework.

mars1129 [50]

So remember that the distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

$\sqrt{(4-4)^2+(-2-(-5))^2}\\ \sqrt{0^2+3^2}\\ \sqrt{0+9}\\ \sqrt{9}\\ 3$

Distance between (4,-5) and (4,-2) is 3 units.

$\sqrt{(1-(-1))^2+(1-4)^2}\\ \sqrt{2^2+(-3)^2}\\ \sqrt{4+9}\\ \sqrt{13}$

Distance between (1,1) and (-1,4) is √13 (or 3.61 rounded to the hundreths) units.

If x varies inversely as y, which statement is true?

grin007 [14]

Answer: The Inverse variation

Step-by-step explanation:

The phrase “ y varies inversely as x” or “ y is inversely proportional to x” means that as x gets bigger, y gets smaller, or vice versa. This concept is translated in two ways. yx = k for some constant k, called the constant of proportionality.

he data shows the distances, in miles, run by runners in a track club. 6, 3, 8, 8, 6, 6, 8, 2, 5, 2, 5, 10, 3, 5 Create a histog

kakasveta [241]

Answer:

To create a histogram of the given data set, we first must check for the frequency of each value.

6, 3, 8, 8, 6, 6, 8, 2, 5, 2, 5, 10, 3, 5

2 - 2

3 - 2

5 - 3

6 - 3

8 - 3

10 - 1

Now that we have the frequencies of each, we need to add them to each range.

0 - 2 : 2

3 - 5 : 5

6 - 8 : 6

9 - 11 : 1

Refer to the image for the histogram.
