Answer:
B
Step-by-step explanation:
To get the probability that at least 8 of the words on the test are words that students know we need to do the following calculations.
<span>=[C(16,8)*C(10,2) + C(16,9)*C(10,1) + C(16,10)*C(10,0)] / C(26,10)
</span>
=0.132
X =
2. -7
7. 15
11. -2
12. 12
13. -1
14. 3
15. 64
16. 5
18. -14
Answer:
x = -5
Step-by-step explanation:
- Subtract 3 from each side, so it now looks like this: 2x = -10
- Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = -5
