Solution: We are given:

\mu=24.8,\sigma =8.5

The z-score is given below:

z=\frac{x-\mu}{\sigma}

        =\frac{52-24.8}{8.5}

        =\frac{27.2}{8.5} =3.2

Therefore, the z-score = 3.2.

The interpretation of z-score is that the team's score is 3.2 standard deviation's above the mean

Q and R are independent events. If P(Q)= 1/8 and P(R)=2/5 find P(Q and R).
Dafna11 [192]
Answer: 1/20
To find P(Q and R), you have to multiply P(Q) by P(R) to get the probability that both events will occur. P(Q) = 1/8, and P(R) = 2/5, so when multiplied together, you get 2/40. This simplifies to 1/20, meaning P(Q and R) = 1/20.

How is the distributive property used to expand expressions? provide an example
Pepsi [2]
Yes the distributive property is used to expand expressions, but it is also used to make it simpler.

3(x+4) + 3(y-8)
This is the same thing as
3x + 12 + 3y -8

Is the graph a linear function, nonlinear function, or Relation ( non-function) ?
anastassius [24]

Answer:

A

Step-by-step explanation:

Because each value of x maps onto only one value of y, it is a function.

However, because it is not the graph of a line, it is a nonlinear function.
