I think the square root of 13 is only an irrational number because it is a decimal number that does not end.

If 5/6 gallons of paint covers 1/4 of the house, then how much paint is needed for the entire house?

tia_tia [17]

Answer:

Step-by-step explanation:

1) If $\frac{5}{6}$ is needed to cover $\frac{1}{4}$ than we need 3 more: $\frac{5}{6}(3)=\frac{15}{6} =2\frac{3}{6} gallons2) But we still need to add the beginning [tex]\frac{5}{6}$ : $2\frac{3}{6}+\frac{5}{6}=2\frac{9}{6}=3\frac{3}6}=3.5$

For the given pair of events A and B, complete parts (a) and (b) below. A: When a page is randomly selected and ripped from

Kitty [74]

Answer:

The two events are dependent.

the probability that events A and B both occur is:

$\frac{1}{2424}\times \frac{1}{2423}=1.7026052585\times 10^{-7}\ or\ 0.00000017$

Step-by-step explanation:

Consider the provided information.

Event A: When a page is randomly selected and ripped from a 2424-page document and destroyed, it is page 2020.

Event B: When a different page is randomly selected and ripped from the document, it is page 1616.

Part(A)

The occurring of one event affects the probability of the other event.

Because if we ripped one page then the probability of ripping second page will going to change as the size of sample space will decrease.

For example: The document has 2424 page, that means size of sample space is 2424. If we ripped another page, the sample size will be 2423. That means event B is depending on event A.

Thus, the two events are dependent.

Part(B)

The probability that events A and B both occur.

If we select a page randomly from 2424-page document, the probability will be: 1/2424

Now we have 2423 pages left in the document as one page is destroyed.

The probability of selecting another page is: 1/2423.

Thus, the probability that events A and B both occur is:

$\frac{1}{2424}\times \frac{1}{2423}=1.7026052585\times 10^{-7}\ or\ 0.00000017$
