Answer:
1152
Step-by-step explanation:
You multiply the 12800 films by 9% to get your answer.
The expression which is equivalent to 1/4 (5x + 6) is; Choice A: {5(1/4)x} + {6(1/4)x}.
According to the question:
- We are required to determine an expression which is equivalent to <em>1/4 (5x + 6).</em>
In a bid to expand the expression; we must multiply each term in the parenthesis by (1/4);
In essence; we have;
- <em>{5(1/4)x} + {6(1/4)x}</em>

Answer:
E(x) = 1.43 (Approx)
Step-by-step explanation:
Given:
Total number of camera = 7
Defective camera = 5
Sample selected = 2
Computation:
when x = 0
P(x=0) = 2/7 × 1/6 = 2/42
P(x=1) = [2/7 × 5/6] + [5/7 × 2/6] = 20/42
P(x=2) = 5/7 × 4/6 = 20/42
So,
E(x) = [0×2/42] + [1×20/42] + [2×20/42]
E(x) = 1.43 (Approx)
