The length of side A in centimeters is 6cm
D. 6
First,

The volume is given by the integral (one of 6 possible combinations),

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.
Alright, so [-2.99] is -2.99, and [2.99] is 2.99, so -2.99+2.99=0
Yesterday = 30 -15
yesterday = 15 minutes
Find the percentage
percentage = 30/15 × 100%
percentage = 2 × 100%
percentage = 200%
