= 12a⁻¹b⁻¹

10.
x²y⁻⁴ * x³y²



11.
(x²)⁰ = 1
12.
(2x²)⁻⁴


the answer is D. twenty-five seconds over one-fourth mile = 100 miles per hour.
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)
58+24=82 is the correct answer to that question because you subtract 2 from 60 then add that to 6 multiplied by 4
It’s 3/2 you can look at the the point (0,1) and (2,4) you can use a method called rise over run you got up 3 over 2 units to get to the next point
