Which of the following is an example of theoretical probability? OA. Elena called 5 friends, and 3 of them were at home. The probability Elena's friends are at home is 3/5 B. A spinner has 8 equal sections numbered 1 ? 8. The probability of spinning the number 3 is 1/8 C. A coin was flipped 100 times, and the results were 53 heads and 47 tails. The probability of heads is 53/ 100 D. Greg turned over 10 playing cards, and 3 of them were aces. The probability of turning over an ace is 3/10
An example of theoretical probability from the considered option is given by: Option 2: A spinner has 8 equal sections numbered 1 to 10. The probability of spinning the number 3 is 1/8
What is experimental probability?Experimental probability calculates the probability of some event from the results of experiments.
For an event E, we get the experimental probability of that event
[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]
where, [tex]P_e(E)[/tex]is denoting experimental probability of occurrence of E.
What is theoretical probability?Probability which is derived theoretically, irrespective of what outcome comes, is called theoretical probability. Probabiltiy which is based on the outcomes of experiments performed is called experimental probability.
Suppose we want to find the probability of an event E.
Then, its theoretical probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
Checking all the options to see which one gives theoretical probability:
Option 1: Elena called 5 friends, and 3 of them were at home. The probability that Elena's friend are at home is 3/5This option uses what was observed from one result. Thus, 3/5 is experimental probability here, as there is no evidence of it being theoretical probability but enough support towards being experimental probability.
Option 2: A spinner has 8 equal sections numbered 1 to 10. The probability of spinning the number 3 is 1/8No experiment is done here, just the description of the setup of the random experiment.
Now, E = event of getting 3 on the spinner.
All spinner's parts are assumingly equally likely, we have:
Number of ways E can occur = 1
Number of ways spinner's outcome can come = 8
Thus, we get P(E) = 1/3
Thus, this option is demonstrating theoretical probability.
Option 3: A coin was flipped 100 times, out of which 53 heads and 47 tails. The probability of heads is 53/100This is using experimental results to get the estimated probability.
Actually, assuming coin being fair, both the tail and heads being equally probable, if we take:
E = event of getting head, then as there are two results possible being Tail or Head (assuming only 2 results), and there is one way of getting head in one toss, so we get:
P(E) = 1/2 = 0.5
Thus, this option is demonstrating experimental probability instead of theoretical one.
Option 4: Greg turned over 10 playing cards, and 3 of them were aces. The probability of turning over an ace is 3/10It is using the data from one experiment. So its experimental probability. Sometimes we can get experimental probability = theoretical probability value, but still, there'd be difference of how you calculated it from the start. Usually, if calculated from experiment, then its experimental probability, and if calculated virtually and based on theories, it is theoretical probability.
Thus, an example of theoretical probability from the considered option is given by: Option 2: A spinner has 8 equal sections numbered 1 to 10. The probability of spinning the number 3 is 1/8

richard has two circular sprinklers to water his rectangular backyard as shown.
Answer:
109.88 ft² (nearest hundredth)
Step-by-step explanation:
Formulae
Area of a rectangle = width × lengthArea of a circle = πr²To find the area of the lawn that is not watered, subtract the area of the 2 circles from the area of the rectangle.
From inspection of the diagram
width of rectangle = 2rlength of rectangle = 4rarea = 512 ft²Substituting the values into the area of a rectangle formula, and solving for r:
⇒ 512 = 2r × 4r
⇒ 512 = 8r²
⇒ r² = 64
⇒ r = ±8
As distance is positive, r = 8 ft
Area of one circle = π8² = 64π ft²
Therefore,
Area not watered = area of rectangle - 2 × area of circle
= 512 - 2(64π)
= 109.88 ft² (nearest hundredth)

The label on the car's antifreeze container claims to protect the car between −40°C and 125°C. To covert Celsius temperature to Fahrenheit temperature, the formula is C equals five ninths times the quantity F minus thirty two.. Write a compound inequality to determine the Fahrenheit temperature range at which the antifreeze protects the car.
Answer:
see below
Step-by-step explanation:
The label on the car's antifreeze container claims to protect the car between -40°C and 125°C.
So inequality which models this situation will be -40°C < T < 125°C
Now we have to show this inequality in Fahrenheit temperature with the help of [tex]C=\frac{5}{9} (F-32)[/tex]
So the compound inequality in Fahrenheit temperature will be

The computation of the figure illustrates that 0.47 expressed as a fraction in simplest form is 43/90.
How to compute the fraction?From the information given, let a = 0.47. Now 10a = 4.777 .... equation i
100a = 47.77 ..... equation ii
Subtract equation i from ii
100a - 10a = 47 - 4
90a = 43
Divide both side by 90
90a/90 = 43/90

The Algebraic equations (x - 20)² and x² - 20 have an equal value My number is 6.
What is an Algebra equation?Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
I think of a number, if I subtract 10 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result.
Let the number be x.
If I subtract 20 from my number that is x - 20 then square the result that is (x-20)².
And if I square my number that is x² then subtract 20 from the result that is x² - 20.
Both the result are the same then we have
(x - 20)² = x² - 20
x² - 20x + 100 = x² - 20
