Answer:
Option C is correct.
The value closest to the actual weight, in pounds of the backpack for the student who had 4 books in the backpack = 13
Step-by-step explanation:
The complete, correct question is presented in the attached image to this solution.
From the table, it is evident that
Intercept = 10.53
Slope = 0.53
Since, the residual plot is analysed with linear regression to obtain the linear relationship between actual weight of the backpack and the number of books in the backpack, the equation relating them must be
y = mx + c
where y = Actual weight of the backpack
m = slope obtained from the analysis = 0.53
x = number of books in the backpack
c = intercept obtained from the analysis = 10.53
So, the relationship is properly written as
y = 0.53x + 10.53
So, when the number of books in the backpack = 4, what is the actual weight of the backpack?
x = 4, y = ?
y = 0.53x + 10.53
y = (0.53×4) + 10 53 = 12.65
To the nearest whole number, 12.65 = 13
Hence, the value closest to the actual weight, in pounds of the backpack for the student who had 4 books in the backpack amongst the options = 13

Answer:
Option b) Gina's systolic blood pressure is 1.50 standard deviations above the average systolic blood pressure of women her age.
Step-by-step explanation:
We are given the following in the question:
The distribution of systolic blood pressure of other women is a bell shaped distribution that is a normal distribution.
z-score = 1.50
Formula:
Let x be the Gina's systolic blood pressure.
Thus, we can write:
Thus, we can write Gina's blood pressure is 1.50 standard deviations above the average systolic blood pressure of women her age.
Option b) Gina's systolic blood pressure is 1.50 standard deviations above the average systolic blood pressure of women her age.
Answer : The cost of one hot hot dog and the cost of one hamburger is, $3.75
Step-by-step explanation :
Let the cost of hot dog be, 'x' and hamburger be, 'y'.
Given:
5 hot dogs and 2 hamburgers cost is, $12.00. The equation will be :
..............(1)
2 hot dogs and 5 hamburgers cost is, $14.25. The equation will be :
..............(2)
Now we have to determine the value of 'x' and 'y' by using substitution method.
............(3)
Now put equation 3 in 2, we get:
y = 2.25
Now put the value of 'y' in 3, we get:
x = 1.5
Cost of hot dog = x = $1.5
Cost of hamburger = y = $2.25
Now we have to calculate the cost of one hot hot dog and the cost of one hamburger.
Cost of 1 hot hot dog and 1 hamburger = x + y
Cost of 1 hot hot dog and 1 hamburger = $1.5 + $2.25
Cost of 1 hot hot dog and 1 hamburger = $3.75
Therefore, the cost of one hot hot dog and the cost of one hamburger is, $3.75
