In a recent year a baseball team paid six times as much to their ace pitcher as they paid to their shortstop. If they paid $56 m

Kobotan [32]

Answer:

pitcher: $48 million
shortstop: $8 million

Step-by-step explanation:

The ratio of salaries can be written as ...

short : pitcher = 1 : 6

Then the fraction of the total that the shortstop received is ...

short : total = 1 : (1+6) = 1 : 7

The shortstop's salary was (1/7)×($56 million) = $8 million.

The pitcher's salary was 6 times that, so 6×($8 million) = $48 million.

The pitcher's salary was $48 million; the shortstop's, $8 million.

Chocolate chip cookies have a distribution that is approximately normal with a mean of 24.2 chocolate chips per cookie and a sta

Allisa [31]

Answer:

Percentile 5

$z=-1.64$

And if we solve for a we got

$a=24.2 -1.64*2.6=19.94$

Percentile 95

$z=1.64$

And if we solve for a we got

$a=24.2 +1.64*2.6=28.46$

Step-by-step explanation:

Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:

$X \sim N(24.2,2.6)$

Where $\mu=24.2$ and $\sigma=2.6$

We want to find the percentiles 5 and 95 for this case.

Percentile 5

For this part we want to find a value a, such that we satisfy this condition:

$P(X>a)=0.95$ (a)

$P(X$ (b)

We want to find a percentile with 0.95 of the area on the left and 0.05 of the area on the right it's z=-1.64. On this case P(Z<-1.64)=0.05 and P(z>-1.64)=0.05

Using this condition we got:

$P(X$

$P(z$

Replacing we got:

$z=-1.64$

And if we solve for a we got

$a=24.2 -1.64*2.6=19.94$

Percentile 95

$z=1.64$

And if we solve for a we got

$a=24.2 +1.64*2.6=28.46$
