Answer:
D. an attribute whose value is indicated by a label.
Step-by-step explanation:
In Mathematics, a random variable can be defined as any variable whose values are determined by the outcome of a random experiment.
Basically, random variables are classified into two (2) main categories and these are;
I. Quantitative random variable: these are variables that are numerical in nature. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
II. Qualitative random variable: these includes variables that are non-numerical in nature i.e they are categorical. For example, the color of a car, gender, shapes etc.
Hence, qualitative can be defined as an attribute whose value is indicated by a label.
What is the x-intercept of the graph below?
Answer:
[tex] \huge \boxed { - 3}[/tex]
Step-by-step explanation:
The graph intercepts x-axis at (-3,0). Therefore x-intercept is - 3.
To find the x-intercept from graph, look where does the graph intercept x-axis at, and that is x-intercept. If the graph doesn't intercept of pass x-axis then there's no x-intercept.

Suppose that the functions s and t are defined for all real numbers x as follows.
s(x)=2x-2
t(x)=3x
Write the expressions for (s-t)(x) and (s+t)(x) and evaluate (s⋅t)(-1)
Answer:
(s-t)(-1) = -1
(s+t)(-1) = -7
Step-by-step explanation:
Given the following set of functions
s(x)=2x-2
t(x)=3x
(s-t)(x) = s(t) - t(x)
(s-t)(x) = 2x - 2 - 3x
(s-t)(x) = -x -2
(s-t)(-1) = -(-1) - 2
(s-t)(-1) = 1-2
(s-t)(-1) = -1
(s+t)(x) = s(t) + t(x)
(s+t)(x) = 2x - 2 + 3x
(s+t)(x) = 5x -2
(s+t)(-1) = 5(-1) - 2
(s+t)(-1) = -5-2
(s+t)(-1) = -7
Suppose h(x) = ax^3 + 11x^2. Determine a if h has an inflection point at x = 4. Show all your work.
Answer:
[tex]a=-11/12[/tex]
Step-by-step explanation:
We are given the function:
[tex]h(x)=ax^3 + 11 x^ 2[/tex]
And we want to determine a such that h(x) has an inflection point at x = 4.
Possible inflection points are whenever h''(x) equals 0. So, we will first differentiate h(x) twice. This yields:
[tex]h'(x)=3ax^2+22x[/tex]
So:
[tex]h^{\prime\prime} (x)=6ax+22[/tex]
Inflection points occur when h''(x) = 0. So:
[tex]0=6ax+22[/tex]
Since we have an inflection at x = 4:
[tex]0=24a+22[/tex]
And solving for a yields:
[tex]a=-22/24=-11/12[/tex]

Answer:
40 degrees
Step-by-step explanation:
The angles of a triangle add together to 180 degrees, so you need to add the two numbers and subtract 180 from the answer you got:
60 + 80 = 140
180 - 140 = 40
Find the equation of the exponential function represented by the table below:
Answer:
[tex]y = 2(4)^{x}[/tex]
Step-by-step explanation:
At x=0
[tex]y = 2(4)^{0} = 2[/tex]
At x=1
[tex]y = 2(4)^{1} = 8[/tex]
At x=2
[tex]y = 2(4)^{2} = 32[/tex]
At x=3
[tex]y = 2(4)^{3} = 128[/tex]

The BMW E30 is the second generation of BMW 3 Series, which was produced from 1982 to 1994 and replaced the E21 3 Series. The model range included 2-door sedan and convertible body styles,[4][5] as well as being the first 3 Series to be produced in 4-door sedan and wagon/estate body styles. It was powered by four-cylinder petrol, six-cylinder petrol and six-cylinder diesel engines, the latter a first for the 3 Series. The E30 325iX model was the first BMW to have all-wheel drive.

can somebody pls show me how to solve this?
Answer:
C. 52.5
Step-by-step explanation:
The total from W(-20) to Z(120) is 140.
You can add up all of the numbers in the ratio, 2:3:3, to get 8
Divide 140 by 8 to get 17.5
Multiply 17.5 times the number in the ratio for each segment, so the new ratio would be 35 : 52.5 : 52.5
Since you are trying to find segment XY, which was the 2nd number in the ratio, you would get your answer as 52.5

By what factor is z multiplied to get z1?
Answer:
The correct answer is -2.
Step-by-step explanation:
"z" = 3+2i, which is (3, 2i) on the graph. You must multiply -2 by 3 and 6, which will give you the plot points for z1, (-6, -4i).
A negative number multiplied into a positive number will result in a negative number.
Therefore, -2 is the correct answer.
Answer:
-2

D.
a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 3
Answer:
a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 2
Step-by-step explanation:
At Image I, we have vertex at point (3,-2), and the length of the left side is of 1 unit(from -2 to -3).
In the larger figure, this length is of 2 units, so the dilation has a scale factor of 2 units. The rotation, due to the coordinates changing, is of 90º counterclockwise(if it was across the x-axis, only the y coordinate would change, but on image II, both coordinates change).
So the correct answer is:
a 90° counterclockwise rotation about the origin, and then a dilation by a scale factor of 2
