Answer:
Option c) The scale on the y-axis misrepresents the difference in the heights of the bars.
Step-by-step explanation:
Given is a histogram that shows the number of properties in a town that are sold within certain periods.
On x axis is given number of days to sell and on y axis the number of properties
X axis is given in interval form with interval width 30 and on y axis scales are marked as 0,1,2....12,13 etc
The mistake is on y axis after 0, 10 is marked with unit distance from 0 but from 10 to 11 also distance is shown as 1 unit.
Hence correct option is
Option c) The scale on the y-axis misrepresents the difference in the heights of the bars.
Answer:
Step-by-step explanation:
The description is too ambiguous to reconstruct the diagram. You need to post the actual diagram.
That diagram is just one way to view division by a fraction. An easier way: DIVIDING by a fraction is the same as MULTIPLYING by the upside-down fraction. For example,
(1/2) ÷ (1/4) = (1/2) × (4/1) = 2
That doesn’t help you answer this particular question, though.
Answer:
Company A and B
Step-by-step explanation:
For company A- 170 is the cost for one hour
For company B- 170 is the cost for one hour
For company C- 175 is the cost for one hour
So company A and B offer the best deal since they both offer $170 per hour.
Answer:
a) P = 0.039
b) The expected number of days is 10 days.
Step-by-step explanation:
The most appropiate distribution to use in this case is the geometric distribution, in order to calculate the probability of a success after k failure trials.
The probability of success, as each of the 10 products are assumed to have fair probabilities, is:
Then, the probability that our product is not selected any given day is:
a) The probability that exactly this product is selected exactly 10 days from now is the probability that is not selected (probbility q) for the next 9 days and selected (probability p) at the 10th day:
b) The expected number of days is calculated as:
