Applicants for temporary office work at Carter Temporary Help Agency who have successfully completed an administrative assistant

dezoksy [38]

Answer:

0.681

Step-by-step explanation:

Let's define the following events:

S: a Carter office worker is rated satisfactory

U : a Carter office worker is rated unsatisfactory

ND: a Carter office worker is placed by Nancy Dwyer

DN: a Carter office worker is placed by Darla Newberg

We have from the original text that

P(S | ND) = 0.8, this implies that P(U | ND) = 0.2.

P(S | DN) = 0.65, this implies that P(U | DN) = 0.35. Besides

P(DN) = 0.55 and P(ND) = 0.45, then we are looking for

P(DN | U), using the Bayes' formula we have

P(DN | U) = $\frac{P(U | DN)P(DN)}{P(U | DN)P(DN) + P(U | ND)P(ND)}$ = $\frac{(0.35)(0.55)}{(0.35)(0.55)+(0.2)(0.45)}$ =0.681

vova2212 [387]

10 cheese pizzas

use simple ratio, 3:2 (3 pepperoni for every 2 cheese)
to make the ratio bigger, we substitute the "3" pepperoni for "15" pepperoni. then take the new amount, 15/3 original, you get 5. then multiply the 2 original cheese pizzas by that 5, and you get 10 cheese pizza's.

hope that helps

What is the maximum number of relative extrema contained in the graph of this function?

Savatey [412]

Answer:

the graph of this function has no local extrema

Step-by-step explanation:

A 5th-degree polynomial graph will have a maximum of 4 local extrema, in general. However, this function has none. The derivative of this function is positive everywhere, so there are no extrema.
