Answer:
<h2>y = 7/8x -1/2 </h2><h2>y = mx+b</h2><h2>m = slope</h2><h2>Slope = 7/8</h2>
Step-by-step explanation:
If you would like to solve 1/(x + 3) = (x + 10)/(x - 2), you can do this using the following steps:
<span>1/(x + 3) = (x + 10)/(x - 2)
</span>1 * (x - 2) = (x + 10) * (x + 3)
x - 2 = x^2 + 3x + 10x + 30
0 = x^2 + 13x + 30 - x + 2
0 = x^2 + 12x + 32
0 = (x + 8) * (x + 4)
1. x = -8
2. x = -4
The correct result would be x = -8 and x = -4.
Answer:
60 Yards.
Step-by-step explanation:
Ooooooooo Proportion question!
We can write an equivalent fraction here:
Because 12 wold be equivalent to the 1 inches.
We can multiply by 12 because 1*12 would be 12.
5*12=60.
x=60, which is the answer.

Answer:
The expected value of:
X = 3 green marbles
Step-by-step explanation:
Number of marbles in a bag = 11
Make-up of the bag = 6 red and 5 green marbles
Sussan selects 7 marbles from the bag
The probability of collecting from 5 of the green marbles = 0.45
The probability of collecting from 6 of the red marbles = 0.55
The expected value of X = the probability of selecting a green marble multiplied by the number of marbles selected
= 0.45 x 7
= 3 green marbles
