Answer:
x = 14.5
Step-by-step explanation:
The diagonals of a rhombus are at right angle to each other, then
∠ BOA = 90° , so
6x + 3 = 90 ( subtract 3 from both sides )
6x = 87 ( divide both sides by 6 )
x = 14.5
1. Square of side= 6cm
2. Rectangle of side= 9cm x 4cm
3. Circle of radius is 6
I believe that it is congruent by SAS
Answer:
$14
Step-by-step explanation:
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%
