"Variability (also called spread or dispersion) refers to how spread out a set of data is. Variability gives you a way to describe how much data sets vary and allows you to use statistics to compare your data to other sets of data. The four main ways to describe variability in a data set are:
<span>Range Interquartile range Variance Standard deviation.
Answer:
In the number 528.8 the value of 8 in the ones place is 10 times the value of 0.8 in the tenths place
Step-by-step explanation:
we have
The number 528.8 miles
Rewrite the number in digits value
so
The value of the ones digit is 8 ones or 8
The value of the tenths digit is 0.8 tenths or 0.8
Find the quotient
8/0.8=10
therefore
In the number 528.8 the value of 8 in the ones place is 10 times the value of 0.8 in the tenths place
Answer:
The probability of a selected car being a 4 door car, given that the car has a sunroof = 0.40
Step-by-step explanation:
The complete question is presented in the attached image.
The conditional probability, of event A happening, given that event B has happened, P(A|B), is given mathematically as
P(A|B) = P(A n B) ÷ P(B)
So, the required probability of a selected car being a 4 door car, given that the car has a sunroof is given as
P (4 doors | sunroof)
= P (4 doors n sunroof) ÷ P(sunroof)
Note that the probability of an event is given as the number of elements in that event divided by the Total number of events.
P (4 doors n sunroof)
= n (4 doors n sunroof) ÷ n (total)
From the Venn Diagram in the attached image,
n (4 doors n sunroof) = 20 + 0 = 20
n (total) = 100
P (4 doors n sunroof) = (20/100) = 0.20
P(sunroof) = n(sunroof) ÷ n(total)
n(sunroof) = 12 + 18 + 20 + 0 = 50
n(total) = 100
P(sunroof) = (50/100) = 0.50
P (4 doors | sunroof)
= P (4 doors n sunroof) ÷ P(sunroof)
= (0.20/0.50) = 0.40
Hope this Helps!!!
