Answer:
0.4
Step-by-step explanation:
Given that:
P(debt) = P(D) = Probability of being in debt = 0.7
P(debt n Midwest) = P(Dn M) = probability of being in debt and lives in Midwest = 0.280
The probability that a randomly selected farmer lives in the Midwest given that he is in debt is?
P(M | D) = p(D n M) / p(D)
P(M | D) = 0.280 / 0.7
P(M | D) = 0.4
Answer:
a. There is more variability in the prices of kid socks because they have a greater range.
Step-by-step explanation:
A measure of variability is a summary statistic that represents the amount of dispersion in a dataset. Common examples are range, interquartile range (IQR), variance, and standard deviation.
From the histogram
Highest Number of Packs of Adult Socks = 7
Lowest Number of Packs of Adult Socks = 5
Range = 7 - 5 =2
Highest Number of Packs of Kid Socks = 7
Lowest Number of Packs of Kid Socks = 4
Range = 7-4 = 3
We conclude that there is more variability in the prices of kid socks because they have a greater range.
The correct option is A.
Answer:
c = 150 + 20b
Step-by-step explanation:
Given:
Ticket charges = $150
Each bag carry cost = $20
Find:
Relationship between bag(b) and cost(c)
Computation:
⇒ Total cost = Ticket charges + $20(number of bags)
⇒ c = 150 + 20(b)
⇒ c = 150 + 20b
