Step-by-step explanation:

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.

Answer:

Pretty sure it's one solution

Step-by-step explanation:

Answer:

An infinite number of solutions.

Step-by-step explanation:

Whenever lines overlap each other, it means they have an infinite number of solutions.

Answer:

total pay $2,750.00

Step-by-step explanation:

first multiply. 03×75,000= $2250.00 (thats how mich commission she has made

then add 500 be she exceeded the 2000 amount

2250+500= $2,750.00

Answer:

B < 400/10

Step-by-step explanation:

The volume of a cylinder is the Area of the base (B) times the height

V(c)  =  B*h           h 0 10 in       then    V(c)  =  10*B

if volume as problem statement is less than 400 in³ then the inequality is:

10*B < 400

B < 400/10

hope this helps!

Step-by-step explanation:

Answer:

Step-by-step explanation:

d-4=19d=15

We move all terms to the left:

d-4-(19d)=0

We add all the numbers together, and all the variables

-18d-4=0

We move all terms containing d to the left, all other terms to the right

-18d=4

d=4/-18

d=-2/9

Step-by-step explanation:

Answer:

The margin of error for a 96% confidence interval is of 0.0114 = 1.14%.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

For this problem, we have that:

[tex]n = 400, p = \frac{395}{400} = 0.9875[/tex]

96% confidence level

So [tex]\alpha = 0.04[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.04}{2} = 0.98[/tex], so [tex]Z = 2.056[/tex].

Calculate the margin of error for a 96% confidence interval.

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]M = 2.056\sqrt{\frac{0.9875(0.0125)}{400}}[/tex]

[tex]M = 0.0114[/tex]

The margin of error for a 96% confidence interval is of 0.0114 = 1.14%.

Answer:

x + y + 1

or

xy + y² + 2

or

x² + y² - 1

or

a²b + b³ + 3

Step-by-step explanation:

You can use x and y as the two variables. Then add them to make is x + y (this is already two variables and two terms). Add a constant, say 1. So x + y + 1, now we have three terms with two different variables and one constant.

Or you can also make it xy + y² + 2 or x² + y² - 1 by adding exponents to each of the variable.

You can choose one from the above or you can make your own (it depends on you).

Answer:

1 second = 6.4 feet

25 seconds = 6.4 * 25 = 160 feet

Answer:

160ft

Step-by-step explanation:

So we already know the unit rate, all we need to do is find how many times the fly can go 6.4 feet in 25 seconds, so our equation is:

25 x 6.4 = 160

So our housefly can fly 160 feet in 25 seconds

Answer:  x = 32°

Step-by-step explanation:

(3x - 4) + (3x - 8) = 180

3x - 4 + 3x - 8 = 180

6x - 12 = 180

6x - 12 + 12 = 180 + 12

6x = 192

6x ÷ 6 = 192 ÷6

x = 32

Answer:

x=3

Step-by-step explanation:

15+17+5x = 47

if you add 15 and 17 just to make it easier, you get....

32+5x = 47

what I did next was minus 32 from each side.

so you are left with....

5x = 15

divide each side by 5 and you get

x = 3

you can go back and make sure that- that is right by doing 15+17=32 and

5x3 = 15 then add them together, 32+15 = 47
