Mean is 6 because once you add up all the numbers it will be 60, and dividing that number by how many you have will give you 6

Median is 5 because once you place the numbers in order, 0, 0, 1, 2, 3, 7, 9, 10, 13, 15 the middle number in the set is between 3 and 7 and once you find the mean of the two you get 5

In a class of all girls, 22 of the 28 students have brown hair. What is the

Verdich [7]

Answer:

$\frac{3}{14}$

Step-by-step explanation:

Total Students = 28

Brown Hair = 22

NOT Brown Hair = 28 - 22 = 6

The probability of an event is the number of that event divided by total number.

So, let denote probability of without brown hair be P(NOT BROWN). So, we can say:

P(NOT BROWN) = 6/28

Reducing, we get:

P(NOT BROWN) = 3/14

Solve the equation for<br> x 3/4(x+21) = 10.5 <br> x =

MrRa [10]

<h3>✍️ Answer:</h3><h3> $x=-\frac{294}{13}$ </h3>

✽✽✽✽

$\frac{x\cdot \:3}{4\left(x+21\right)}=10.5$

$\mathrm{Multiply\:both\:sides\:by\:}4\left(x+21\right)$

$\frac{x\cdot \:3}{4\left(x+21\right)}\cdot \:4\left(x+21\right)=10.5\cdot \:4\left(x+21\right)$

$3x=42\left(x+21\right)$

$3x=42x+882$

$\mathrm{Subtract\:}42x\mathrm{\:from\:both\:sides}$

$3x-42x=42x+882-42x$

$-39x=882$

$\mathrm{Divide\:both\:sides\:by\:}-39$

$\frac{-39x}{-39}=\frac{882}{-39}$

$x=-\frac{294}{13}$

Please help me!<br> Find AC

oksian1 [2.3K]

We are asked to find the length of $AC$ , which measures $7x$ . Using the segment addition postulate, we can add the two given expressions for $AB$ and $BC$ and make it equal to the expression for $AC$ .
$AB + BC=AC$
$5x+1+15=7x$
$5x+16=7x$
$16=2x$
$x=8$
We've found the value of $x$ , but we aren't done yet. We need to plug in the value we got for $x$ into the expression for $AC$ , which is $7x$ . Therefore, $AC \Rightarrow7x\Rightarrow7(8)\Rightarrow\boxed{56}$ . Hope this helped and have a great day!
