Answer:
25%
Step-by-step explanation:
Assuming that each child can only be a boy or a girl, then each child will have a probability of 0.5 or 50% of being either gender. Therefore, since we need to find the probability of at least 2 being boys then we simply need to multiply this probability twice.
0.50 * 0.50 = 0.25 or 25%
Using this data we can say that there is a 25% probability of there being at least 2 boys in the family.
You need to subtract the two cutouts on each side, so the side of the box would be 24- 2x. X would then become the height of the box once folded.
The volume is found by multiplying the 4 dimensions:
The volume becomes x(24-2x)^2
Now take the derivative of the formula to solve for x
Dv/dx= (24-2x)^2 + x^2(24-2x)*-2
= 24-2x(24-2x-4x)=0
X =12 or 4
24-2x = 24-2(4) = 24-8=16
Volume = 16 x 16 x 4 = 1024 cubic inches.
Answer:
0
Step-by-step explanation:
(3,5) and (-1,5)
slope= y2-y1 divided by x2-x1
so,
=5-5/-1-3
=0/-4
=0
At x=2, y=4
At x=4, y=16
So the total change in y from x=2 to x=4 is 16-4=12
And since average rate of change = total change in y divided by total change in x within the same period, therefore the answer is 12/2 = 6

Answer:
there are 12 sections
here is how to do it:
2 8
_ = _
3 x
so you cross multiply
8 x 3 = 2x
24=2x
12=x
