What do you mean? It would help if you were more specific...
4 + 3/5(15 + 2x) = 25
4 + 0.6(15 + 2x) = 25
4 + 9 + 1.2x = 25
13 + 1.2x = 25
1.2x = 12
x = 10
I hope this helps!
We are given frequency distribution in the question
to find the probability distribution from frequency distribution we need to divide frequency by total number of observations.
Here, total number of observations are 6+10+7+5=28
so , we will have probability distribution table as
X 0 1 2 3
P(x) .21 .35 .25 .17
probability distributiuon describes all possible values that a random variable can take within a given range.
frequency distribution is the presentation that presents number of observation in given interval.
Answer:
B Most grandparents do Not feel safe entering their account information online
Step-by-step explanation:
Percent means out of 100

68 out of 100 grandparents do not feel safe entering their data
