Answer:

The first quartile is 5

The third is 8

The interquartile is the difference between the first and third quartile.

The interquartile is 3

Step-by-step explanation:

First, make a list of all the numbers. To find the first quartile, you have to first find the median. The median is the first 7 in the list.

Everything before 7 is the lower percentile of the range.

The firsr quartile is the median of the lower percentile.

The lower list is:

2,3,4,4,5,6,6,6

The median of this list is 5.

The process for finding the third quartile is the same except the list is the higher percentile which is the list of numbers above the median.

What is the length of segment AC

lakkis [162]

To find the length of segment AC, we must find the total rise and total run between the two points.

Point C is located at (-5, 5). Point A is located at (3,-1). To find the rise, subtract the y-value of A from the y-value of C:

$5 - (-1) = 6$

The rise of this segment is 6.

To find the run, subtract the x-value of A from the x-value of C:

$3 - (-5) = 8$

The run of this segment is 8.

We can use the Pythagorean Theorem to find the length of this segment. The theorem uses the following formula:

$a^{2} + b^{2} = c^{2}$

The segment represents the hypotenuse, and the rise and run represent the legs of this segment. We know that the two legs' lengths are 6 and 8, so plug them into the equation:

$6^{2} + 8^{2} = c^{2}$
$36 + 64 = c^{2}$
$100 = c^{2}$

Square root both sides to get c by itself:

$\sqrt{100} = 10$
$c = 10$

The length of segment AC is 10.

4. Coach Kent brings 3 quarts of sports druk U

murzikaleks [220]

Answer:

6 ounces of the drink each player get.

Step-by-step explanation:

Given:

Coach Kent brings 3 quarts of sports druk U soccer practice.

He gives the same amount of the drink to each of his 16 players.

Now, to find ounces of the amount of drink each player get.

1 quart = 32 ounces.

So, 3 quarts = 32 × 3 = 96 ounces.

As given the amount of drink to each player get the same.

Thus, to get the amount of drink each player get we divide the amount of drink by number of players:

$\frac{Amount\ of\ drink}{Number\ of\ players}$

$=\frac{96\ ounces}{16\ players}$

$=6\ ounces\ per\ players.$

Therefore, 6 ounces of the drink each player get.
