Answer;
0.3430
Solution and explanation;
Probability of a product being acceptable is 70% or 0.7
Probability of the product being defective is 30 % or 0.3
Therefore; If three of the products are randomly selected, the probability that all of them are acceptable will be;
= 0.7 × 0.7 ×0.7 or 0.7 ³ = 0.3430
= 0.3430 .
The answer would be 0.5. You're welcome!
F(g(x)) = (x^2) + 4x - 5
g(f(x)) = (x^2) -7
Answer:
1. y = 5
2. y = 15
Step-by-step explanation:
Step 1. Subtract 4x from both sides
8 = 7.2 + 5x - 4x
Step 2. Simplify 7.2 + 5x - 4x to 7.2 + x
8 = 7.2 + x
Step 3. Subtract 7.2 from both sides
8 - 7.2 = x
Step 4. Simplify 8 - 7.2 to 0.8
0.8 = x
Step 5. Switch sides
Answer: x = 0.8
