Answer:
97.8%
Step-by-step explanation:
110 is 2 standard deviations above the mean (6+6 = 12)
12+98 = 110
Looking at the standard deviation curve
P(x< or = to 110) = 1 - P(x>110)
We can find the probability that x>100 by adding anything above 2 standard deviations above the curve.
P(x>110) = 2.1+.1 = 2.2%
P(x< or = to 110) = 1 - P(x>110)
= 1- 2.2%
= 1- .022
= .978
= 97.8 %
Answer:
x=5
Step-by-step explanation:
-12=8-4x
-20=-4x
5=x
Answer:
The mean is: 85
Step-by-step explanation:
First you need to add everything up :
1 * 2 = 2
2 * 1 = 2
3 * 3 = 9
4 * 5 = 20
5 * 4 = 20
6 * 3 = 18
7 * 2 = 14
(I multiplyed them all first because i was fast than doing 4+4+4+4+4 because its the same as 4 * 5)
then add them all up 2+2+9+20+20+18+14=85
Answer:
The median is: 4
Step-by-step explanation:
Get the data in NUMERICAL ORDER (smallest to largest), then eliminate the extremes until we're at the middle. (basically chopping off the end till you get to the middle) Therfore The answer would be 4.
Answer:
The mode would be: 4
Step-by-step explanation:
The mode is Get the data in NUMERICAL ORDER, and see which value is the most frequent (we can have more than one mode).
Answer:
25%
Step-by-step explanation:
firs you do 5 divided by 20 because there are 20 x's. this will = 0.25
0.25 = 25%
I hope I get brainiest. Sorry for taking forever. Have a nice day!
