Rebecca Wilson was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 846

RUDIKE [14]

Answer:

Number of two point goals = 169

Number of three point goals = 123

Number of free throws = 139

Step-by-step explanation:

Let the number of two point goals = $x$

Let the number of three point goals = $y$

Let the number of free throws = $z$

As per the given statements:

$x = 2y-77 ...... (1)$

$z = x-30 ...... (2)$

Using equation (1):

$z = 2y-107$ ...... (3)

Total number of points from two point goals = $2x$

Total number of points from three point goals = $3y$

Total number of points from free throws = $z$

$2x+3y+z=846$

using (1) and (3):

$2(2y-77)+3y+2y-107=846\\\Rightarrow 4y-154+5y-107=846\\\Rightarrow 9y-261=846\\\Rightarrow 9y=846+261\\\Rightarrow 9y=1107\\\Rightarrow y =123$

By (1):

$x = 2\times 123-77 =169$

By (3):

$z =2\times 123-107 = 139$

So, answers are:

Number of two point goals = 169

Number of three point goals = 123

Number of free throws = 139

Stats To quality for a police academy, applicants are given a lest of physical Itness. Ihe scores are normallyDistributed with a

omeli [17]

Since we want just the top 20% applicants and the data is normally distributed, we can use a z-score table to check the z-score that gives this percentage.

The z-score table usually shows the percentage for the values below a certain z-score, but since the whole distribution accounts to 100%, we can do the following.

We want a z* such that:

$P(z>z^*)=0.20$

But, to use a value that is in a z-score table, we do the following:

$\begin{gathered} P(zz^*)=1 \\ P(zz^*)=1-0.20=0.80 \end{gathered}$

So, we want a z-score that give a percentage of 80% for the value below it.

Using the z-score table or a z-score calculator, we can see that:

$\begin{gathered} P(zNow that we have the z-score cutoff, we can convert it to the score cutoff by using:[tex]z=\frac{x-\mu}{\sigma}\Longrightarrow x=z\sigma+\mu$

Where z is the z-score we have, μ is the mean and σ is the standard deviation, so:

$\begin{gathered} x=0.8416\cdot9+64 \\ x=7.5744.64 \\ x=71.5744\cong72 \end{gathered}$

so, the cutoff score is approximately 72.
