Answer:
A.) ŷ = 7X + 27.625
B.) check Explanation
C.) $77,000
Step-by-step explanation:
Given the following :
Education(x) : 3 4 6 2 5 4 8 0
Salary (y) : $40 36 56 35 72 47 107 52
A.) Using the linear regression calculator :
ŷ = 7X + 27.625
Salary = 7(education) + 27.625
B.) The Coefficient for education refers to the gradient or slope of the linear graph, the Coefficient is the ratio of the change in salary earned to education. The slope, which is the Coefficient of education is 7.
C.)What is the predicted salary for an individual who completed 7 years of higher education?
ŷ = 7X + 27.625
Salary = 7(education) + 27.625
Salary = 7(7) + 27.625
Salary = 49 + 27.625
Salary = $76.625
Salary = $77,000 ( nearest whole number)
Answer:
"between 32 and 37"
Step-by-step explanation:
You can clearly look at the number line and see that each small line represents 1 unit.
Look at the box.
The left side of the box coincides with 2 units after 30, so 30 + 2 = 32
THe right side of the box coincides with 2 units after 35, so 35 + 2 = 37
Hence, the box part of the box plot contains all the values between 32 and 37

For what it's worth, two views of the graph of the equation are attached
The point values are astronomical!
The probability is given by the following formula:
Probability = number of favorable outcomes / total number of outcomes
The total number of outcomes is 10, 3 of the initial number of marbles are red and 2 of them are orange.
The probability of getting a red marble in the first draw is:
Probability = 3/10
The probability of getting an orange marble in the second draw is:
Probability = 2/10 = 1/5
the probability that he will choose a red and then an orange marble can be calculated by multiplying the probabilities that we found, then we get:
Probability = 3/10 × 1/5 = 3/150 = 1/50
Then, the answer is 1/50
