The number of sheets of paper available for making notebooks is 75,000.

Aleks [24]

Answer:

If each sheet of paper were to make 8 pages, then you must multiply 75,000 by 8 to find the total amount of pages will be available to make notebooks.

75,000x8=600,000

Now, each notebook contains 200 pages so you must divide 600,000 by 200 to distribute the pages within the notebooks.

600,000/200=3,000.

In conclusion, 3,000 notebooks can be made from the paper currently available in your problem

A motorist is driving eastbound at the posted maximum speed along a stretch of University Parkway in Baltimore. The probability

ICE Princess25 [194]

Answer:

0.7

Step-by-step explanation:

Let A and B be the events

A = the motorist encountered a red light at the 1st intersection

B = the motorist encountered a red light at the 2nd intersection

Then we have

$P(A) = 0.4$

$P(B|A) = 0.7 \; (P(B) \; given \; A \; occurred)$

$P(B|A^c) = 0.2 \; ( where\; A^c \; is \; the \; complement \; of \; A)$

We want to find P(A|B), the probability that A occurred given that B occurred.

Using Bayes' Theorem we have

$P(A|B)=\frac{P(B|A)P(B)}{P(B|A)P(B)+P(B|A^c)P(A^c)}$

So,

$P(A|B)=\frac{0.7P(B)}{0.7P(B)+0.2(1-P(A))}=\frac{0.7P(B)}{0.7P(B)+0.12}$

and we just need to find P(B)

But

$0.7=P(B|A)=\frac{P(B\cap A)}{P(A)}=\frac{P(B\cap A)}{0.4}\Rightarrow P(B\cap A)=0.28$

and

$0.2=P(B|A^c)=\frac{P(B\cap A^c)}{P(A^c)}=\frac{P(B\cap A^c)}{0.6}\Rightarrow P(B\cap A^c)=0.12$

Since

$(A\cap B)\cap (A\cap B^c)=\emptyset \;and\;(A\cap B)\cup (A\cap B^c)=B$

We have

$P(B)=P(A\cap B)+P(A\cap B^c)=0.12+0.28=0.4$

and finally,

$P(A|B)=\frac{0.7P(B)}{0.7P(B)+0.12}=\frac{0.7*0.4}{0.7*0.4+0.12}=\frac{0.28}{0.4}$

$\boxed{P(A|B)=0.7}$

Answer:

d=5√2 unit

Step-by-step explanation:

distance between two points d=√(x2-x1)²+(y2-y1)²

two pints (-3,-4) and (4,-5)

d=√(4-(-3)²+(-5-(-4)²

d=√(4+3)²+(-5+4)²

d=√49+1

d=√50

d=√25*2

d=5√2
