Which statement correctly describes the function on a given interval?
A. The function is decreasing and nonlinear between x= -7 and x= -3
B. The function is increasing and nonlinear between x= -3 and x= -1
C. The function is decreasing and linear between x= -1 and x= 1
D. The function is increasing and linear between x= 1 and x= 3
Answer:B !!!
Step-by-step explanation:
Option D is correct, the function is increasing and linear between x= 1 and x= 3.
What is a function?A relation is a function if it has only One y-value for each x-value.
By observing the graph we say that the function is increasing and linear between x= 1 and x= 3
For a function y = f(x), if the value of y increases on increasing the value of x, then the function is an increasing function.
Linear functions are those whose graph is a straight line
Hence, option D is correct, the function is increasing and linear between x= 1 and x= 3.

The area of a parallelogram can be found by finding the product of its height and base. The area of the resulting figure is 105/4 sq. ft.
What is a Parallelogram?A parallelogram can be defined as a quadrilateral which has equal and parallel opposite sides. The sum of the adjacent angles of a parallelogram is equal to 180° and its opposite angles are equal.
Each side of the square is given 4 1/2 ft,
And the height of each parallelogram 1 1/2 ft.
Now, the area of square is (side)^2 and the area of parallelogram is height × base.
Thus, area of given figure is given as,
Area = (4 1/2)^2 + 2×(4 1/2)×( 1 1/2)
= 105/4 sq. ft.
Hence, the area of the given figure is 105/4 sq. ft.

Suppose that E and F are points on the number line.
If EF = 12 and E lies at -9, where could F be located?
Answer:
either at -21 or 3
Step-by-step explanation:
we know that the length is a total of 12 so it either goes 12 spaces to the left or to the right of -9
-9 - 12 is -21 and -9 + 12 is 3

Which of the following equations correctly describes the graphed line?
y = -1/2x - 5
y = -1/2x + 5
y = 1/2x + 5
y = 1/2x - 5
Answer:
Option C i.e. y = 1/2x + 5 is the correct option.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slope b is the y-interceptGiven the points
A(4, 7)
B(-4, 3)
Determining the slope between A and B
(x₁, y₁) = (4, 7) (x₂, y₂) = (-4, 3)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [3 - 7] / [-4 - 4]
= -4 / -8
= 4/8
= 1/2
Thus, the slope of the line = m = 1/2
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 5
Thus, the y-intercept b = 5
now substituting m = 1/2 and b = 5 in the slope-intercept form
y = mx+b
y = 1/2x + 5
Therefore, the equation of line in the graph is:
y = 1/2x + 5
Thus, option C i.e. y = 1/2x + 5 is the correct option.

Determine the probability of 6 different lower case letters (Question continuation)
There are 26 lower case letters.
The first can be any of letters 26
The second can be any of letters 26 - 1
The third can be any of letters 26 - 2
The fourth can be any of letters 26 - 3
The fifth can be any of letters 26 - 4
The sixth can be any of letters 26 - 5
Number of selection is:
[tex]Selection = 26 * (26 - 1) * (26 - 2) * (26 - 3) * (26 - 4) * (26 - 5)[/tex]
[tex]Selection = 26 * 25 * 24 * 23 * 22 * 21[/tex]
[tex]Selection = 165765600[/tex]
The probability is:
[tex]Probability = \frac{Tries}{Selection}[/tex]
[tex]Probability = \frac{1000000}{165765600}[/tex]
[tex]Probability = 0.00603261472[/tex]

∠ABC = ∠CDA (given)
∠BCA = ∠DAC (given)
CA = AC (common side)
ASA congruence criterion = when two angles of two triangles are equal and their included side is also equal, we can consider those triangles to be congruent to each other.
Since two angles in triangle △ABC and△CDA are equal and since their included side is also equal we can conclude that they are congruent.
Therefore, △ABC ≅ △CDA under the ASA congruence criterion.

Below are five questions from a survey of MBA students. Answers were written in the blank at the left of each question. For each question, state the data type (categorical, discrete numerical, or continuous numerical) and measurement level (nominal, ordinal, interval, ratio). Explain your reasoning. If there is doubt, discuss the alternatives. _____ Q11 What is the age of the car you usually drive
Complete question :
Q11. What is the age of the car you usually drive? (years).
Q12.) About how many times in the past year did you attend formal religious services?
Q13.) How often do you read a daily newspaper? (0 = Never, I = Occasionally, 2 – Regularly).
Q14.) Can you conduct simple transactions in a language other than English? (0 = No. 1 = Yes).
Q15. How often do you exercise (aerobics, running, etc)? (0 = Not at All. 1 Sometimes. 2 = Regularly)
Answer:
Continous, ratio
Discrete, Ratio
Categorical, ordinal
Categorical, nominal
Categorical, ordinal
Step-by-step explanation:
Continous variables usually do have an infute number of values inbetween consecutive integers while discrete numeric variables take up whole number values and has a finite number of values. The
Categorical variables are used for Qualitative variables which takes up labels rather than numeric values.
The measurement scales include ;
Ratio scale used for quantitative variables with a true zero value (that is 0, means there is no value for the variable at that point, on a ratio scale with height variable = 0 then there is no height for the measured point). it allows for mathematical calculation of data values as it has a fixed distance between point.
The interval scale is similar ot the ratio aside that it does not have a true zero value, the zero point only serves as a reference point.
The nominal scale, when numbers are used to depict Qualitative variables, such that there is no rank or order in the label. If labels are 0 and 1 for each options, then one label is not superior or inferior to the other
Ordinal variables on the other hand have a particular order or rank for the Qualitative data represented with numerical values :
Here : for a scale of 1 - 5 ; the magnitude increases from 1 through 5
1. continuous numerical, ratio
2. discrete numerical, ratio
3. categorical, ordinal or interval
4. categorical, nominal
5. categorical, ordinal or interval
