Answer:
2.5
Step-by-step explanation:
2.5(4k+2) =12k
2.5*6k=12k
Answer:

Step-by-step explanation:
We can split the shape into a right triangle and a rectangle.
tan θ = opp/adj
Let c be the missing base for the right triangle.
tan45 = 4/c
c = 4/tan45
c = 4
x = 3 + 4
x = 7
sin θ = opp/hyp
sin45 = 4/y
y = 4/sin45
y = 
Answer: False
Step-by-step explanation: To find the mean time add all the times and divide by the amount of times you have, which is 9.
0 + 15 + 30 + 90 + 105 + 120 + 45 + 60 + 75 = 540 total minutes spent.
Now divide 540 by 9 to get the mean time. 540 divided by 9 = 60.
So the mean is 60 minutes, not 75 minutes.
Therefore the statement below is False.
Y=4x shows y as the total earnings and x as the number of windows
Probability is (outcome wanted)/(total possible outcomes). Total possible outcome is the whole area of the rectangle. Which is (18)(12)=216. The outcome wanted is just the area of the triangle. (0.5)(2)(5)=5. Now 5/216=0.02
