Answer:
r=3.25
Step-by-step explanation:
7/2,14/4,21/6,28/8,35/10,42/12,49/14,56/16,63/18,70/20
A stem and leaf plot (histogram) shows the mode as the longest list of "leaves." It is the easiest to use for finding mode.
A box-and-whisker plot tells you nothing about relative frequencies.
A scatter plot or line graph would require careful re-interpretation to determine the mode. If the amount of data is large and there are many data values with about the same high frequency, these charts may be unhelpful, too.
Answer:
#7 = 430
#9 = 16
#11 = 930
Step-by-step explanation:
7 to the power of 2 is 49 / 49+3 is 52 / 52-9 is 43 / 43x10 is 430
66 divided by 11 is 5 / 5 +3 is 8 / 8 X2 is 16
18 -3 is 15 / 15 + 3 is 18 / 18 to the power of 2 is 324 / 324 - 14 is 310
310x3 is 930
So calculate the probability
that is
(desired outcomes)/(total possible outcomes)
desired oucomes=green
so take the spins from20 and 200 and 2000
tota=20
deriedoutcome=0
0/20=0
total=200
desired outcomes=7
7/200=0.035
total=2000
disired outcomes=95
95/2000=0.0475
average the 3 results
(0+0.035+0.0475)/3=0.027
0.027=x/20
multily both side by 20
0.5
round up
1
the answer is A, 1
