5.92 x 10 to the power of 13 (I think)
If two segments are both parallel to a third line they must be:
c. Parallel to each other
Answer:
Option C
Step-by-step explanation:
The central Limit Theorem says the sampling distribution of the sample mean is approximately normal under certain conditions
The conditions are
i) the population should be symmetrial. If population is skewed sample size should be sufficiently large atleast 30
ii) Samples should be drawn strictly at random
iii) the sample observations should be independent
Thus we find that option a is not necessary because even for skewed large sample size allows the theorem
Option b is not correct since if population is less than 30, sampling itself is not necessary.
Option d is also wrong since normality is not necessary
Only option C) The sample size must be large (e.g., at least 30) is the necessary condition
Answer:
First question: A, Second question: B
Step-by-step explanation:
0.5= 1/2
0.25= 1/4
0.4= 2/5
Now, insert these numbers, as fractions, back into the equation:
Following PEMDAS you will get 1 as your answer.
19) 3/8
24 - 15 = 9
9/24 = 3/8
20) 3/28
8 total people running. We want to know the probability that both the president and vice-president are girls, so we have to assume that the president is a girl first.
3/8 x 2/7 = 6/56 = 3/28
21) Travis should play the game where he has to pick either an A or B out of a hat which contains letters A, B, C, D, and E. The probability of him drawing an A or B and winning is 2/5, or 0.4. If he plays the other game, then the probability of him winning is only 1/3, or 0.33.
Probability of rolling a 2 or 3 on a die = 2/6 = 1/3 (0.33)
Probability of picking an A or B = 2/5 (0.4)
