Answer 1

Answer:

In bold answers with correct units

3) 6 x 3 = 18 + 1/2 x 12 x 15 = 90 = 90+ 18 = 108ft^2

4) = 12 x 12 = 144 + 4x4 = 16 +12 x 4 = 48 = 144+12+48 = 204m^2

5) = 8 x 12 = 96 + 1/2 x 4 x 6 = 12 = 108ft^2

6) = 3x 3 = 9  + pi3^2 =  28.2743339 (x2) =56.5486678 + 9 = 65.5m^2

proves 4 semi circles = 2 circles

7) 10 x 8 = 80 +4 x 4 = 16 + 1/2 x 2 x 4 = 4 = 20+80= 100ft^2

proves 14-8-4 = 2ft is the triangle length and 10-6 = 4 the triangle height.

8) 4x6 = 24 + 1/2 x 4 x 2 = 4 + pi 4^2 = 1/2 x 50.2654825 = 24+4 + 25.1329 = 53.1m^2

Answer 2
3. 108
4. 204
5. 108
6. 65.5
7. 100

Tree dies are rolled and the results are shown and multiplied. If the product is an even number, how high is the probability that the sum of those numbers is also even?

Answers

Step-by-step explanation:

If I roll a die three times, what is the probability the product of the three numbers is odd?

If I roll a die three times, what is the probability the product of the three numbers is odd?Once you multiply by an even number, the outcome is guaranteed to be even. So it's the chance that all die are odd.
