Answer:
D)She may not be correct because means cannot be determined from Box plots.
Step-by-step explanation:
Box plot -Boxplot is a way to show the spread and centers of a data setboxplot and also called a box and whisker plot,
Box plot tells us about :
1) Mininmum value
2) 25th Percentile value
3)Median
4) 75th Percentile value
5)Maximum value
6) Interquartile Range
Now we are given that By looking at the plots, Beth says that the two means are about 5 years apart.
So,Option D is true
She may not be correct because means cannot be determined from Box plots.
Answer:
1 / 2
Step-by-step explanation:
- First observe that the fate of the last person is determined the moment either the first or the last seat is selected! This is because the last person will either get the first seat or the last seat. Any other seat will necessarily be taken by the time the last guy gets to 'choose'.
- Since at each choice step, the first or last is equally probable to be taken, the last person will get either the first or last with equal probability: 1/2
- Armed with the key observation, we see that the event that the last person's correct seat is free, is exactly the same as the event that the first person's seat was taken before the last person's seat.
- Well, each person had to make a random choice, was equally likely to choose the first person's seat or the last person's seat - the random chooser exhibits absolutely no preference towards a particular seat. This means that the probability that one seat is taken before the other must be 1/2
Step-by-step explanation:
123456 less then 7
unlimited greater then 7
Is 12 Because the pattern is 2+1=3; 4+2=6;
6+3=9; 8+4=12 and 10+5=15
Well, the average of a sum of number is found by adding each given number and dividing that number by the amount of given numbers.
Example: 5+4+3+8=20
and 20/4 = 5, the average of the numbers
Multiply 1.8 by 8.0 using this format:
1.8
x8.0
