Please help! i can’t write the equation on here so look at the picture.

Anvisha [2.4K]

Answer:

So if x= 1 , y= -20 , z = -5 , we just have to replace those values on the equation

$\frac{\sqrt{yz}}{(z-x)^{2} + y } =$ $\frac{\sqrt{(-20) * (-5)}}{(-5-1)^{2} + (-20) } =$ $\frac{\sqrt{100}}{(-6)^{2} -20 }$ $= \frac{10}{16} =\frac{5}{8}$

Eddi Din [679]

Answer:

D. 0.821

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The combinations formula is important to solve this question:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Desired outcomes

The order is not important. For example, Elisa, Laura and Roze is the same outcome as Roze, Elisa and Laura. This is why we use the combinations formula.

At least 3 girls.

3 girls

3 girls from a set of 5 and 2 boys from a set of 3. So

$C_{5,3}*C_{3,2} = 30$
