Answer:

D.\frac{4}{36}

Step-by-step explanation:

Solution,

Two dice are thrown.

So we have to find out the total number of outcomes.

(1,1),\ (1,2),\ (1,3),\ (1,4),\ (1,5),\ (1,6)

(2,1),\ (2,2),\ (2,3),\ (2,4),\ (2,5),\ (2,6)

(3,1),\ (3,2),\ (3,3),\ (3,4),\ (3,5),\ (3,6)

(4,1),\ (4,2),\ (4,3),\ (4,4),\ (4,5),\ (4,6)

(5,1),\ (5,2),\ (5,3),\ (5,4),\ (5,5),\ (5,6)

(6,1),\ (6,2),\ (6,3),\ (6,4),\ (6,5),\ (6,6)

The total number of outcomes = 36

We have to find out the probability of outcomes that add up to 9.

So, Possible outcomes are;

<u>(3,6),\ (4,5),\ (5,4),\ (6,3)</u>

The total number of possible outcomes = 4

Now, according to the formula of probability,

P(E)=\frac{Total\ number\ of\ Possible\ outcomes}{Total\ Number\ of\ outcomes}

P(of\ add\ up\ to\ 9)=\frac{4}{36}

Hence the correct option is D)4/36.

At 8am,Ming Wei started travelling from Town A to Town B.At 8:40am, Ali started travelling from Town B to Town A.Mingwei's speed
Vesnalui [34]
Let's write some equations.

Mingwei's distance from Town A after x hours from 8:00 is 45x.

Ali's distance from Town B after x hours is 30x-20, since he doesn't start walking for 40 minutes.

When Mingwei's distance is twice Ali's, they've met up (since their distance from Town A is twice their distance from Town B).

So, this gives 45x=60x-40, so 15x=40, so x=\frac{40}{15} = \frac{8}{3}, so the time is 10:40.

After \frac83 hours, Mingwei has traveled 45 * 8 / 3 = 120 kilometers while Ali has traveled sixty, so the distance between the towns is 180 kilometers.

Dafna1 [17]

Answer:

$133.20

Step-by-step explanation:

Since the amount of hours she worked isn't a whole number, we can first separate 18 and 1/2 and work the problem out one at a time.

1. Multiply 7.20 by 18 to get 129.60

2. Multiply 0.50 by 7.20 to get 3.60.

3. Add 129.60 and 3.60 together to get the answer, 133.20.
