Answer:
The probability is 0.136125
Step-by-step explanation:
45% are in favor of the project, the probability of selecting someone in favor of the project will be 45/100 = 0.45
The probability of selecting someone not in favor of the project = 1 - probability of selecting someone in favor of project = 1-0.45 = 0.55
Now we have 3 people to be chosen at random with exactly one of them favoring the new building project. This means two of them will not favor the building project
Thus the probability here is = the probability of favoring * the probability of not favoring * the probability of not favoring
= 0.45 * 0.55 * 0.55 = 0.136125
Answer:
Slope: 1
Y-intercept: -1
Step-by-step explanation:
The line touches the y-axis at -1, and using rise over run for the slope, it would be 1, since you go up 1 unit and move to the right 1 unit. 1/1 which is our rise/run would be 1 and that would make the slope 1.
I hope it helps! Have a great day!

Answer:
It would change the median by 7.5 and change the mean by 170
Step-by-step explanation:
My maths might be wrong but i think this is it
Solve
4y+8=6y+3
minus 4y from both sides
8=2y+3
minus 3 fro mboth sides
5=2y
divide both sides by 2
2.5=y
well, it it actually open since there is a variable
it is true, but only for 1 value of y
answer is OPEN
Answer:
+5x+6.
Step-by-step explanation:
Here you can use the foil method.
1. Multiply x by x to get .
2. Multiply x by 3 to get 3x.
3. Multiply 2 by x to get 2x.
4. Multiply 2 by 3 to get 6.
Now, you have to add all those terms to get +3x+2x+6 and you can simplify that to +5x+6.
