Luba_88 [7]

Answer:

Allen go to bed at <u>9:15 p.m</u>.

Step-by-step explanation:

Given:

Allen started his homework at 8:10 p.M. And worked for 45 minutes. Then he phoned a friend and talked for 20 minutes. He went to bed when he finished the call.

Now, to find the time Allen go to bed.

Allen started his homework at 8:10 p.m.

And worked for 45 minutes.

So, to get the time when he finished homework is by adding 45 minutes and the time when he started homework:

$8.10+45$

$=8.55\ p.m.$

Thus, he finished his homework at 8:55 p.m.

Then he phoned a friend and talked for 20 minutes and went to bed when he finished the call.

<em>As, 1 hour = 60 minutes.</em>

Now, to get the time when he go to bed by adding 20 minutes and the time when he finished homework:

$8.55+20=9.15\ p.m.$

Therefore, Allen go to bed at 9:15 p.m.

You randomly choose one of the morales.Without replacing the first marble, you choose a second marble. What is the probability o

IrinaK [193]

Let’s say, hypothetically speaking, you chose the second marble without replacing the first marble so, events are hypothetically dependent. Events are dependent if the occurrence of one hypothetical event hypothetically does affect the likelihood that the other events occur. The probably of two or more dependent events A and B is the probability of A times the probability of B after A hypothetically occurs

P(A and B) = P(A) x P(B after A)

Choose the first marble

The total number of hypothetical marbles are, hypothetically speaking, 4 on a hypothetical basis, and there is one red marble.

P(red)=1/4

Choose the second marble

Without hypothetically replacing the hypothetical first marble, you choose the hypothetical marble, hypothetically speaking. So, the total hypothetical number of marbles are, hypothetically, 3, and there is, hypothetically, one green marble.

P(green) = 1/3

The probability of choosing red and then, hypothetically, green is:

P(red and green) = P(red) x P(green)
=1/4 x 1/3

= 1/12

P(red and green) is hypothetically equal to 1/12 on a hypothetical account.

Final hypothetical answer: 1/12

A traveling circus with thrill rides charges $6 for admission plus $2.50 for each ride you take. If you pay $31.00 total, how ma

sergeinik [125]

Answer:

10 rides

Step-by-step explanation:

$6 is for admission (fixed), so if you paid $31 in total, $6 went to admission, so you had $31 - $6 = $25 left for the rides.

If each ride costs $2.50 and you have $25 to ride, the number of rides you took was:

$\frac{25}{2.5}=10$

So 10 rides
