Two standard dice are rolled and their face values multiplied. What is the probability that the product is prime or ends in a 5?

icang [17]

Answer:

6/21

Step-by-step explanation:

1. First, check all the possible combinations for a pair of dice:

1-1

1-2 2-2

1-3 2-3 3-3

1-4 2-4 3-4 4-4

1-5 2-5 3-5 4-5 5-5

1-6 2-6 3-6 4-6 5-6 6-6

(Those are the numbers of the dice, separated by hyphons.)

2. Next, find out the products, since that is the info we need to go off of.

1

2 4

3 6 9

4 8 12 16

5 10 15 20 25

6 12 18 24 30 36

(those are all the products based on the same chart we saw above.)

3. Now, let's calculate the probability.

Find the amount of prime numbers. (1, 2, 3, 5) Looks like there are four total.
Find the amount of numbers that end in a five. (15, 25) There are two. I've skipped 5 because that is already on the list.
Find the total amount of numbers. There are 21 in our case.

4. There are 6 numbers that will satisfy our needs. (prime or ending in 5)

There are 21 total.

6/21

If you need decimal form, there is a

0.2857 chance.

Hope this helped.

Caps hock Guess and Check (or use Algebra) to solve #3 & # 4 3. Plato has 36 coins in nickels, dimes, and quarters. The numb

Sedaia [141]

Answer:

Part 1:

Let the nickels be = n

Let the dimes be = d

Let the quarters be = q

Plato has 36 coins in nickels, dimes, and quarters. So, equation forms:

$n+d+q=36$ .....(1)

The number of nickels is three less than twice the number of dimes.

$n=2d-3$ ....(2)

The total value of the coins is $5.20.

$0.10d+0.05n+0.25q=5.20$ .... (3)

Substituting n=2d-3 in (1) and (3)

$2d-3+d+q=36$

=> $3d+q=39$ ....(4)

$0.10d+0.05(2d-3)+0.25q=5.20$

=> $0.10d+0.10d-0.15+0.25q=5.20$

=> $0.20d+0.25q=5.35$ ...(5)

Multiplying (4) by 0.25 and subtracting (5) from (4)

$0.75d+0.25q=9.75$ now subtracting (5) from this we get;

$0.55d=4.4$

=> d = 8

Substituting d = 8 in $3d+q=39$

$3(8)+q=39$

$24+q=39$

=> q = 15

Substituting values of d and q in $n+d+q=36$ , we get n

$n+8+15=36$

$n=36-23$

=> n = 13

Therefore Plato has 13 nickels, 15 quarters and 8 dimes.

Part 2:

Let the original price of the ski hat be = x

Original price was marked down by 35% means value was lowered by 35%.

So, we can calculate as:

$x-\frac{35x}{100}=15.60$

=> $\frac{65x}{100}=15.60$

=> $65x=1560$

x = 24

Hence, the original price was $24 but after 35% marking down, it was available for $15.60.

If angle MNP is an equilateral triangle, find x and the measure of each side

fomenos

Answer:

x = 13

Each side = 27

Step-by-step explanation:

As triangle is an equilateral triangle, all the sides of the triangle are equal.

So,

⇒ 4x - 25 = x + 14

⇒ 3x = 39

⇒ x = 13

hence, measure of each side will be;

each side = 4x - 25

= 4(13) - 25

= 27.
