Answer:
Inter quartile range.
Step-by-step explanation:
We have been given that the amount of money that college students spend on rent each month is usually between $300 and $600. However, there are a few students who spend $1,300.
We know that range, interquartile range, variance and standard deviation are the measures of spread.
Since $1300 is large valued outlier as mostly students spend between $300 and $600, so mean of our given data set will be grater than median and our given data is skewed to right.
Since range, variance and standard deviation are not good measure of spread for skewed data, therefore, inter-quartile range would be the most appropriate to measure the amount of money that college students spend on rent per month.
if a = b and b = c, then a = c.
In this case if y = - 7 and -7 = z then y = z .................>(y = a, -7 = b and z = c)
Answer: B)
transitive property of equality
C, D, and E would all be Statistical Questions.
Answer:
B
Step-by-step explanation:
Answer
• x = –1
• y = –2
• z = 1
Explanation
Given the system:
We have to divide equation 1 over 5 and add it to equation 2:
Now, we have to add 1/5(equation 1) to equation 2:
Next, we multiply the equation 2 obtained previously times 5:
Then, we divide equation 2 over 4:
We add it to equation 3:
Then, we are left with:
Simplifying:
Now that we have the value of z (z = 1), we can replace it in the modified equation 2 and solve for y:
Finally, calculating the value of x with any of the equations (as we already have the other two values):
