The answer is 2.35714285714!
hope this helps!!
Add all the chips to find the total amount.
7 + 9 + 3 + 6 = 25 chips
Since there are 6 blue chips (6/25), that's the probability of just getting once.
When you pick a blue chip and it doesn't get replaced, then that means there is one fewer blue chip and one fewer from the total amount.
5/24
Multiply both probabilities.
6/25 * 5/24 = 30/600
Simplify.
30/600 → 1/20
Therefore, the answer is B
Best of Luck!
Answer:
y=(x-2)(x+2)
Step-by-step explanation:
The table and graph show the line crossing the x axis at -2 and +2. That means when x is either of those two values, y will be 0.
If we set each equation to zero, we should find those two values of x. I'll skip right to the second equation, since I can see that it would meet those criteria:
y=(x-2)(x+2)
0=(x-2)(x+2)
x = 2 and x = -2

<u>#7</u>
1. Find the volume of the pyramid (l×w×h/3); you should get 64cm³
2. Find the volume of the cube (l×w×h); you should get 512cm³
3. Add the two products; the glass paperweight's volume is 576cm³
<u>#8</u>
1. Find the surface area (SA) of the cube (area of one square×5); it is 320cm²
2. Find the SA of the pyramid (exclude the square base); it is 80cm² ((slant height×(length/2))×4)
3. Add the surface areas; the sum should be 400cm²
The number of parts is:
4+7= 11
33 photos/ 11 parts= 3 photos/part
Group 1: 4 parts* (3 photos/ 1 part)= 12 photos
Group 2: 7 parts* (3 photos/ 1 part)= 21 photos
