Answer:
11/23 or 0.478
Step-by-step explanation:
1. Find the probability of selecting 2 red chips:
11/23 * 10/22 = 5/23
2. Find the probability of selecting 2 blue chips:
12/23 * 11/22 = 6/23
3. Add the two probabilities:
5/23 + 6/23 = 11/23 = 0.478 (rounded to 3 decimal places)
hope this helps! <3
Dear Kellyeasterday, 11 1/4 inches is more precise.
First you set up the problem- 7/12=x/100. then you cross multiply 7×100=700 then divide 12 into 700 so 700÷12=58.333333333333 and so your percentage is 58.3%
To find the x intercept of the function, we would find g(x) = 0
To do this, we would set each expression in the piecewise function to zero and solve for x. We have
For
x/3 + 2 = 0
let us multiply both sides of the equation by 3. We have
x/3 * 3 + 2 * 3 = 0 * 3
x + 6 = 0
x = - 6
- 6 is less than - 1
- 6 < - 1
It satisfies the inequality. Thus, x = - 6 is in the domain
For
4x - 2 = 0
adding 2 to both sides of the equation, we have
4x - 2 + 2 = 0 + 2
4x = 2
Dividing both sides of the equation by 4, we have
4x/4 = 2/4
x = 1/2
x = 1/2 is less than 1. It is not in the domain of this equation. Thus, there is no x interscept at x = 1/2
Therefore, the x intercept of the piecewise function is (- 6, 0)
$252/$28=9 lawns. $252 is the total money they earned, so divide it by the amount of money they charge per lawn.
