Say the total allowance is X.
4/9X=$28
Therefore 28/(4/9) = $63
Answer:
Approximately 11 feet.
Step-by-step explanation:
Let the length of the third side of the triangle be represented by x. Applying Cosine rule, we have:
=
+
- 2abCos C
⇒
=
+
- 2(8 x 12) Cos
= 64 + 144 - 192 x 0.42262
= 208 - 81.143
= 126.857
x = 
= 11.2631
x ≅ 11
The length of the third side of the triangle is approximately 11 feet.
Answer:
E(x) = 7.05
Step-by-step explanation:
We are given the following information in the question:
x: 1 2 4 8 16
p(x): 0.05 0.10 0.30 0.40 0.15
Formula:

Hence, the expectation of the given data is 7.05
