Answer For A: 1:2 probability

Answer For B: 3:4 probability

Step-by-step explanation: Since there is 3 odds and 3 evens in a 6 sided dice, there is 1:2 probability for you to land on a even or a odd. But if you were to roll the dice twice, your probability rate increases by half. So your probability rate for winning if rolled twice is 3:4.

Morgarella [4.7K]

Answer:

The actual distance between the historical markers is 18 miles.

Step-by-step explanation:

Given : On a map, the distance between two historical markers is 4.5 inches, and 2.5 inches represents 10 miles.

To find : What is the actual distance between the historical markers?

Solution :

We have given that,

2.5 inches represents 10 miles.

i.e, 1 inch represent $\frac{10}{2.5}$ miles.

1 inch = 4 miles.

Now, The distance between two historical markers is 4.5 inches.

The actual distance between the historical markers in 4.5 inch is

$4.5 \text{ inch}=4.5\times 4\text{ miles}$

$4.5 \text{ inch}=18\text{ miles}$

Therefore, The actual distance between the historical markers is 18 miles.

C) P, Q, and R are prime numbers such that<br> 3 * P + 7 * Q + 15 * R = 102.<br> What is Q?

lana66690 [7]

Answer:

Q = 3

Step-by-step explanation:

3 * P + 7 * Q + 15 * R = 102

7Q = 102 - 3P - 15R

Q = (102 - 3P - 15R)/7

Try P = 2; R = 3

Q = 51/7 not an integer

Try P = 2; R = 5

Q = 21/7 = 3

Solution: P = 2; Q = 3; R = 5

Answer: Q = 3
