Total surface area of cuboid is = 12x18x2 + 10x12x2 +18x10x2
=432+240+360
=1032
Surface of the 1 cube =2x2x2 = 8
Surface of the all cubes = 8x270 = 2160
Answer:D
Step-by-step explanation:
Multiplying out 2(g-h):
2g -2h = b+4
Taking 2h on the right hand side of the equation:
2g = b+4 +2h
Dividing by 2 on both sides:
g = b/2 +2 +h
Answer: 0.29 (29%)
Step-by-step explanation:
women who gave birth at a certain hospital last year:
over 30 years old - 0.48
unmarried - 0.46
over 30 or unmarried (or both) - 0.65
what is the probability that a woman who gave birth at the hospital was both unmarried and over 30 ?
We know that
P(A and B) = P(A) + P(B) - P(A or B)
P(+30 and unmarried) = P(+30) + P(unmarried) - P(+30 or unmarried)
P(+30 and unmarried) = 0.48 + 0.46 - 0.65 = 0.29
Answer:
The slope is 4 and y-intercept is actually 3... (I hope)
Remember rise over run, here you can see that it goes up 4 and over 1.
I am so sorry, I'm not good at explaining
