Answer:
y=2
Step-by-step explanation:
6(-3)+3y=-12
-18+3y=-12
3y=-12-(-18)
3y=-12+18
3y=6
y=6/3
y=2
Answer:
1)9 2)18 3)9. 4)4. 5)carpeting
Step-by-step explanation:
1) divide 63 by 7 = 9
2)multiply 54 by 2 = 108 total weight of the boxes then divide 108 by 6 to get 18
3) 75 -30 to get remaining amount which is 45 then divide by 5 to get how much he will pay each month which is 9
4 24- 12= 12 the remaining for the 3 and divide by 3 to get 4
5) multiply 6 * 9 which is $54 which is cheaper than the $81
Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
Mean 
= 70 inches
Standard deviation 
= 3 inches
Average basket ball player 
= 79 inches
Since it is normally distributed assume with 5% significance .
So, it becomes,
At 0.05 level of significance , 0.0013 = 0.13% of the adult male population is taller than the average basketball player .
Hence, First Option is correct.

Answer:
radius = 5 cm
Step-by-step explanation:
The point of "show your work" is to have to do exactly that. If you know the answer to the problem, you are being requested to show how you got it. If you got it by using a web calculator, then show your input and its result.

If you worked the problem yourself, you probably did it by filling in numbers in the equation for the area of a circle:
A = πr²
78.5 = 3.14×r²
Dividing both sides by 3.14 gives the square of the radius:
78.4/3.14 = r² = 25
Taking the positive square root gives the radius:
r = √25 = 5
The area is in square centimeters, so the radius is in centimeters:
radius = 5 cm
