For a population with a mean of u = 40 and a standarddeviation of o = 8, find the z-score corresponding toeach of the following

ivann1987 [24]

Solution:

Given the mean and standard deviation;

$\mu=40,\sigma=8$

The z-score formula is;

$z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

(a)

$\begin{gathered} x=34,n=1 \\ \\ z=\frac{34-40}{\frac{8}{\sqrt{1}}} \\ \\ z=-0.75 \end{gathered}$

(b)

$\begin{gathered} x=34,n=4 \\ \\ z=\frac{34-40}{\frac{8}{\sqrt{4}}} \\ \\ z=-1.5 \end{gathered}$

(c)

$\begin{gathered} x=34,n=16 \\ \\ z=\frac{34-40}{\frac{8}{\sqrt{16}}} \\ \\ z=-3 \end{gathered}$

This year the boys’ basketball team won 4 times as many games as it lost. The team played a total of 40 games. How many games di

Salsk061 [2.6K]

Answer:

The team won 32 games.

Step-by-step explanation:

x = games won

y = games lost

z = total games = 40

x = 4y Won 4 times as many games as it lost

x + y = 40 Games won + games lost = Total games played

4y + y = 40 Sub 4y in for x, as established previously

5y = 40

y = 8

x = 4y

x = 4(8)

x = 32

The team won 32 games.
