Answer:
P(x< 18) = 0.986
Step-by-step explanation:
Step 1: find the z-score using the formula, z = (x - µ)/σ
Where,
x = randomly chosen values = 18
µ = mean = 7
σ = standard deviation = 5
Proportion of the population that is less than 18 = P(x < 18)
Plug in the values into z = (x - µ)/σ, to get z-score.
z = (18 - 7)/5
z = 11/5 = 2.2
Step 2: Find P(x< 18) = P (z<2.2) using z-table.
The probability that corresponds with z-score calculated is 0.986.
Therefore,
P(x< 18) = 0.986
1. One trillion
2. 500,000,000,000 x 2
3. 250,000,000,000 x 4
4. 1,000,000,000,000 x 0
5. 5 billion + 5 billion
There are many many many more but here's a few. :/
1st one I believe I’m not 100% sure
Step-by-step explanation:
- move 2.4x to the left-hand side and change its sign.
- move y to the right-hand side and change its sign.
- Divide both sides of the equation by -2.4
