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.

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.

Fraction in simplest form

nataly862011 [7]

Answer:

14/15 meters

Step-by-step explanation:

We add each color of fabric to find the total amount of fabric used.

1/3 +3/5

We need to get a common denominator of 15

1/3 *5/5 = 5/15

3/5*3/3 = 9/15

5/15 + 9/15 = 14/15

Find f(x) and g(x) so the function can be expressed as y = f(g(x)) y = Seven divided by x squared. + 10

Damm [24]

F(x) = 7/x
g(x)=x²+10

Then f(g(x))= 7/(x²+10)

By the way g(f(x))=(7/x)² + 10

Help me on questions 8 through 12

mr_godi [17]

8. To find the answer you can eather multipy it for each of the sides or you can add it 6 times once for each side
$15\frac{1}{4} \times 6 \\ \\ 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4} + 15 \frac{1}{4}$
9. You basicly do the same thing as the previous problem but with the new numbers and you add each number 2 times

10. For are you multiply Base × Height So all you have to do is Multiply the 2 numbers shown together
$2 \frac{1}{2} \times 5$
11-12 Is the same but witb the new numbers

I hope this helps!
