Answer:
The correlation coefficient for the data shown in the table is:
r=1
Step-by-step explanation:
We are given a data set as:
x y
0 15
5 10
10 5
15 0
Cl;early from the data set we could see that as the x-value is increasing by a constant term i.e. 5 than the y-value is also decreasing by a constant term i.e. 5.
Hence, the function that can be best used to describe these data points is:
y= -x+15
This means that there is a negative correlation.
Also, the relationship is strictly linear as all the data point lie above these line.
Hence, we know that for a strong linear relationship.
Hence, the correlation coefficient is: 1

Question:
In a neighbourhood pet show, each of the animals entered is equally likely to win. if there are 7 dogs, 6 cats, 3 birds, and 2 gerbils entered, what is the probability that a bird will win the top prize?
Answer:
Probability that a bird will win the top prize is 0.167
Step-by-step explanation:
Given:
The number of dogs = 7
The number of cats = 6
The number of birds = 3
The number of gerbils = 2
To Find:
Probability that a bird will win the top prize = ?
Solution:
Let us first find the total number of pets .
The Total number of pets = 7 + 6 + 3 + 2 = 18
Now the probability of a bird will win the top prize is
