Answer:
5.) B 6.) A
Step-by-step explanation:
A(Rhombus) = 1/2(9)(12) = 54 cm²
Answer:
<u>13</u>
<em>Explanation:</em>
11×2-9=13
Since he spent half of his allowance on the movies and he had 11 left, you would multiply 11 x 2. Next, subtract 9 because that is not part of his allowance. You will end out with <u>13.</u>
multiply -2/25 x 5 hours
-2/25 x 5/1 = -10/25 = -2/5
Answer:
h=16
Step-by-step explanation:
We multiply each side by 2 to get rid of the 1/2 on the left side, and so h=16
Answer:
p(4 successes) ≈ 7.7%
Step-by-step explanation:
p(k successes in n trials) = C(n,k)·p^k·(1-p)^(n-k)
You have n=5, k=4, p=0.4, so the probability is ...
p(4 successes) = C(5,4)·(0.4)^4·(1 -0.4)^1 = 5·0.4^4·0.6 = 0.0768
p(4 successes) ≈ 7.7%
