Answer:
6
Step-by-step explanation:
We can use ratios to solve
15 ft 18ft
---------- = -----------
5ft x
Using cross products
15x = 5*18
15x = 90
Divide by 15
15x/15 = 90/15
x =6
D 28/4=7 that is the answer for the question
25233 is your answer for this problem
Answer:
Step-by-step explanation:
The concept of variance in random variable is applied in solving for the value of c for the estimator cW1 + (1 − c)W2 to be most efficient. Appropriate differentiation of the estimator with respect to c will give the value of c when the result is at minimum.
The detailed analysis and step by step approach is as shown in the attachment.
