The fact that the first chosen student was a girl is already decided, so there is no need to find the probability of that happening. There are a total of 13+10, or 23 students. A girl was already selected, so that leaves 22 students. The chance that a boy is chosen is 10/22, or 5/11.
<span>To find the confidence interval, add and subtract the margin of error from the mean.
With mean 18.7 and margin of error 5.9, you have 95% confidence the answer is between 12.8 and 24.6.</span>
Answer:
Step-by-step explanation:
Given a large enough sample size the probability is 100%
If the question is "What is the probability of catching 3 tennis balls in three tosses in mid air. Sample size is 3
0.74³ = 0.405224 or about 41%
Exact=56.5 rounded would be 57 because you can't make half a birdhouse.
Answer:
D. d = 
Step-by-step explanation:
Use the distance formula: d = 
The two points are (6, -2) and (3, -9)
Plug the values into the formula:
d = 
Simplify
d = 
d = 
d = 
I hope this helps :))
