Answer:
The correct option is 2.
Step-by-step explanation:
The given data set is
22, 23, 23, 21, 18, 4, 17, 15, 23, 20, 24, 15, 25, 16
Arrange the data is ascending order.
4, 15, 15, 16, 17, 18, 20, 21, 22, 23, 23, 23, 24, 25
Divide the data in 4 equal parts.
(4, 15, 15), 16, (17, 18, 20), (21, 22, 23), 23, (23, 24, 25)
Now, we can say that
The interquartile range of the data set is
If the data lie in the interval , then the data set has not outliers.
All the data lie in the interval [5.5,33.5] except 4. So, 4 is an outlier of the given data.
There is one outlier that indicates an unusually small number of assignments required in that class. Therefore the correct option is 2.

Answer:
The point (0, 1) represents the y-intercept.
Hence, the y-intercept (0, 1) is on the same line.
Step-by-step explanation:
We know that the slope-intercept form of the line equation
y = mx+b
where
- m is the slope
- b is the y-intercept
Given
- The point (-6, -3)
- The slope m = 2/3
Using the point-slope form
where
- m is the slope of the line
- (x₁, y₁) is the point
In our case:
- m = 2/3
- (x₁, y₁) = (-6, -3)
substituting the values m = 2/3 and the point (-6, -3) in the point-slope form
Subtract 3 from both sides
comparing with the slope-intercept form y=mx+b
Here the slope = m = 2/3
Y-intercept b = 1
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
Given the line
at x = 0, y = 1
Thus, the point (0, 1) represents the y-intercept.
Hence, the y-intercept (0, 1) is on the same line.
Answer:
x = 5 and x =
Step-by-step explanation:
To find the zeros equate f(x) to zero, that is
(2x - 1)(x - 5) = 0
equate each factor to zero and solve for x
2x - 1 = 0 ⇒ x =
x - 5 = 0 ⇒ x = 5
