Answer:
{x | x = –5, –3, 1, 2, 6}
Step-by-step explanation:
The domain is the list of first-values of the ordered pairs:
{x | x = –5, –3, 1, 2, 6}
Answer:
Residual = -2
The negative residual value indicates that the data point lies below the regression line.
Step-by-step explanation:
We are given a linear regression model that relates daily high temperature, in degrees Fahrenheit and number of lemonade cups sold.
Where y is the number of cups sold and x is the daily temperature in Fahrenheit.
Residual value:
A residual value basically shows the position of a data point with respect to the regression line.
A residual value of 0 is desired which means that the regression line best fits the data.
The Residual value is calculated by
Residual = Observed value - Predicted value
The predicted value of number of lemonade cups is obtained as
So the predicted value of number of lemonade cups is 23 and the observed value is 21 so the residual value is
Residual = Observed value - Predicted value
Residual = 21 - 23
Residual = -2
The negative residual value indicates that the data point lies below the regression line.
Answer:
In a survey of 2,300 people who owned a certain type of car, 1,610 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
1610/2300x100=
70%
Step-by-step explanation:
total number of people for the survey= 2300
those that wanted to buy the car= 1610
percentage= 1610/2300x 100=0.7x 100
percentage= 70%
Answer:
The greatest value is "e"
Step-by-step explanation:
We have the following equations:
a. 1.31 a = f
b. 1.12b=f
c. 1.01c=f
d. 0.98d=f
e. 0.31e =f
Then solving for "a", "b", "c", "d" and "e" we have:
a. a = f /1.31
b. b=f/1.12
c. c=f /1.01
d. d=f / 0.98
e. e=f / 0.31
Now, given that in all the equations "f" represents the same number, the gratest value it's going to be the option in which "f" is divided by the smaller number.
The option in which f is divided by the less number is option e because, in this case, f is divided by 0.31.
Answer:
MN = LK because of the definition of a 'parallelogram'.
Step-by-step explanation:
We are given a parallelogram KLMN.
We know that a 'parallelogram' is a quadrilateral which have two opposite sides parallel and equal in length.
Therefore, from parallelogram KLMN, we get,
MN║LK and ML║NK
MN = LK and ML = LK.
Hence, we that MN = LK because of the definition of a 'parallelogram'.
