Answer:
Side of square bottom=6.46 m
Height of box=4.31 m
Step-by-step explanation:
Let s be the side bottom
Height of box=h
Volume of box=
Volume of box=
Cost of bottom=$40 per square m
Cost of sides =$30 per square m
Total cost=
Differentiate w.r.t s
Again,differentiate w.r.t s
Substitute s=6.46
Hence, the cost is minimum at s=6.46
Side of square bottom=6.46 m
Height of box=4.31 m
Answer:
0.889
Step-by-step explanation:
I think it is multiplied.
10 *9 = 90
which is the total number of ways you can draw 2 cards without replacement.
I think it is easier to figure out how many possibilities there are over 62 and go from there.
10*9
10*8
10*7
===========
9*8
9*7
So there are 5 combinations that are over 62. There are 5 more possibilities because you could draw them in the reverse order
9 * 10
8 * 10
7 * 10
8* 9
7 * 9
In all there are 10 ways of drawing numbers that are over 62
So what is the probability of drawing 2 cards above 62?
10/90 = 1/9 = 0.111
Therefore, there must be a probability of 1 - 0.111 for under 62 = 0.889
I think you add both of them together and you get 145
Answer:
y≥2-4
Step-by-step explanation:
Simplify your equation.
4x-2y≤8
-4x -4x
-2y≤-4x+8
/-2 /-2
y≥2-4
Answer:
Step-by-step explanation:
<em>Slope= </em> =
You want to use the slope as y2-y1 over x2-x1. So you subtract 6 from 12 and 5 from negative 3. Hope this helps.
