As, given correlation coefficient for your data set is= -0.015
It means there is weak relation between two variables.If value of correlation coefficient is near to 1 or -1, it shows there is strong correlation.
Negative correlation means, if one quantity is increasing other is decreasing.So, the value of -0.015 shows that there is very less correlation between x and y values or two values in data set.
So, the chances are very less that predicted value will be reasonably close to the actual value as the points will be far from line of best fit.
probability that a randomly chosen college student either has a job or lives on campus.
What is probability?
- Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true.
- The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
To find the probability that a randomly chosen college student either has a job or lives on campus:
Given: 85% of college students have a job, 54% live on campus, and 42% have a job and live on campus.
So, out of 100 students, 42 students either has a job or live on campus.
43 college students have a job and 12 live on campus.
So, 43 + 42 + 12 = 85 + 54 - 42
85 + 12 = 139 - 42
97 = 97
Therefore, probability that a randomly chosen college student either has a job or lives on campus.

Answer:
D
0.4
Step-by-step explanation:
P(A)=0.6
P(B)=0.3
P(B∩A)=0.5
P(A∪B)=P(A)+P(B)-P(A∩B)
P(A or B)=P(A∪B)=0.6+0.3-0.5=0.9-0.5=0.4
Set ' D ' is the only set of numbers that can be the
lengths of a triangle's sides. A, B, and C can't.
