Answer:
C. The random variable is discrete. The possible values are x= 0, 1, 2... 100
C. The random variable is continuous. The possible values are a > 0.
Step-by-step explanation:
Here is the complete question :
Determine whether the random, variable is discrete or continuous.
In each case, state the possible values of the random variable.
(a) The number of people in a restaurant that has a capacity of 100
(b) The square footage of a house.
(a) Is the number of people in a restaurant that has a capacity of 100 discrete or continuous?
A. The random variable is discrete. The possible values are 0≤x≤ 100.
B. The random variable is continuous. The possible values are 0≤x≤ 100.
C. The random variable is discrete. The possible values are x= 0, 1, 2... 100
D. The random variable is continuous. The possible values are x= 0, 1, 2... 100
b) Is the square footage of a house discrete or continuous?
A. The random variable is discrete. the possible values are a > 0
B. The random variable is discrete. The possible values are a = 1, 2, 3...
C. The random variable is continuous. The possible values are a > 0.
D. The random variable is continuous. The possible values are a = 1,2, 3,
A discrete variable is a variable that can be counted. It has a finite amount of values. The number of people in the restaurant is finite. It cannot exceed 100. At any point in time when you count the number of people in the restaurant and it would be between 0 - 100
A continuous variable has an infinite amount of values it can take on. The square footage of a house can be of any size. there is no limit to the size of a house. it can be as small or big as the architect's imagination allows.

1 foot is equal to 12 inches. How many inches are in 2 feet, 6 inches
Answer:
30 inches
Step-by-step explanation:
If there are 12 inches in one foot, then that means that 2 feet is double 12, or 24. Plus, we have the 6 inches added, so we must add 24 + 6, which is 30 inches in total. Hope this helps!

Answer:
12.5 cm
Step-by-step explanation:
Triangle IDA is a 3-4-5 right triangle with a scale factor of 5. That is, segment AI is 25 cm long. Since IS is half the length of the diagonal, it is ...
IS = (25 cm)/2
IS = 12.5 cm
__
If you like, you can work out the length of AI using the Pythagorean theorem:
AI² = DI² +DA²
AI = √(15² +20²) = √(225 +400) = √625 = 25

Find the volume of a right circular cone that has a height of 5.4 m and a base with a diameter of 5.1 m. Round your answer to the nearest tenth of a cubic meter.
The volume of a right circular cone has a height of 5.4 m and a base with a diameter of 5.1 m is 90.07 cubic meter.
How to find the volume of a right circular cone?Suppose that the radius of the considered right circular cone is 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]
The right circular cone is the cone in which the line joining the peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.
The volume of a right circular cone has a height of 5.4 m and a base with a diameter of 5.1 m.
[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]
[tex]V = \dfrac{1}{3} \times 3.14 \times 2.5^3 \times 5.4 \: \rm unit^3\\\\= 270.23 / 3\\\\= 90.07[/tex]

Find the probability of drawing a 10 from a standard deck
of 52 cards,
Answer:
4/52 or 1/13 (simplified)
Step-by-step explanation:
There are 4 "10's" in a pack.
This means you have the chance to pick 4 10's.
So out of 52 cards, you can get 4.
4/52 -> Which can be simplified to 1/13.
This is the probability of getting a 10 (once) in a standard deck of cards.
The probability of drawing a 10 from a standard deck of 52 cards is 1/13.
Number of 10's in a standard deck of 52 cards =4
Total cards =52
What is probability?Probability is the measurement of the possibilities of events.
P(event) =Favorable outcomes/ Total possible outcomes
Here, Favorable outcomes =4
Total possible outcomes =52
P(10) =4/52
P(10) =1/13
So, the probability of drawing a 10 from a standard deck of 52 cards =1/13
Thus, the probability of drawing a 10 from a standard deck of 52 cards is 1/13

A ship’s captain sights the top of a 200 foot cliff at a 17° angle of elevation. How far is the ship from the base of the cliff? Round to the nearest foot.
Answer:
654 ft
Step-by-step explanation:
in this case you have a SOH-CAH-TOA problem.
we need Adjacent and opposite so we use tan
tan (17) = O/A
tan (17) = 200ft / x
x = 654.17 ft

An online music store charges you $5.95 for 5 songs. How much would it cost you to
buy 14 songs?
Answer:
It would cost $16.66
Step-by-step explanation:
To find the individual cost of one song you would divide $5.95 by 5 since that's what it costs for 5 songs. Each individual song costs $1.19. So then you multiply $1.19 by the 14 songs and get the answer of $16.66

Find the indicated side of the
right triangle.
45
y
9
45°
х
y = [?]
Answer:
y = 9√2
Step-by-step explanation:
By applying Pythagoras theorem in the given right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
y² = 9² + x²
By the property of isosceles triangle,
Two angles of the right triangle are equal in measure, opposite sides of these equal angles will be equal in measure.
Therefore, x = 9
y² = 9² + 9²
y² = 81 + 81
y² = 162
y = √162
y = 9√2

(A) - 1 1/2
(B) -1
(C) 2 1/2
(D) 3 1/2
(D)
Answer:
-1 is the correct answer
Step-by-step explanation:
Move that many points on the number line
The position of B on number line is at - 1.
What is Number line?Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
Given that;
Point A is shown on the the number line below.
And, Another point, B , is to be placed on the number line and will be 2 1/2 unit from point A.
Now,
Since, The position of Point A = 1 1/2
And, Another point, B , is to be placed on the number line and will be 2 1/2 unit from point A.
So, The point B = 1 1/2 + (-2 1/2)
= 3/2 - 5/2
= - 2/2
= - 1
Thus, The position of point B = - 1
