Answer:
4 times c is 4c and 4 times 3 is 12 so the answer would be 4c + 12
Step-by-step explanation:
Answer:
a)
b)
c) For this case in order to find the number of people who would support the bike lanes we just need to multiply the estimated proportion by the total size and we got:
Step-by-step explanation:
For this case we have an interval for the true proportion of adults in a certain town who want to add bike lanes to a major roadway:
Part a
For this case the point of estimate is given by:
Part b
We can estimate the margin of error with this formula:
Part c
For this case in order to find the number of people who would support the bike lanes we just need to multiply the estimated proportion by the total size and we got:
Answer:
Julie is 20
Janet is 23
Their brother is 12
Step-by-step explanation:

Answer:
find the slope of each line and make sure they are opposite reciprocals
Step-by-step explanation:
example, if slope of one line is -3/4 then a line that is perpendicular would have a slope of 4/3
Answer:
Step-by-step explanation:
P(0 personality in common) = 39/375 = 0.104
P(1 personality in common) = 69/375 = 0.184
P(2 personality in common) = 110/375 = 0.2933
P(3 personality in common) = 122/375 = 0.325
3
P(4 personality in common) = 35/375 = 0.093
3
b) No the probability did not add up to 1 because they do not cover the entire sample space
c) Sample space is 0, 1, 2, 3, 4 personality preferences in common
