Tyler believes that an 8-sided die can be used to predict whether customers at his store will use a coupon when making their purchases, with a roll of 1 indicating a coupon and all other outcomes indicating no coupon. Today, 4 of the first 48 customers in the store used a coupon. How does the experimental probability of a customer using a coupon compare to the theoretical probability of Tyler’s die? The experimental probability is greater than the theoretical probability by more than 2%. The experimental probability is less than the theoretical probability by more than 2%. The experimental probability is greater than the theoretical probability, but within 2%. The experimental probability is less than the theoretical probability, but within 2%.
The correct answer choice is; The experimental probability is less than the theoretical probability by more than 2%.
How does the experimental probability of a customer using a coupon compare to the theoretical probability of Tyler’s die?It follows from the task content that, upon evaluation;
The experimental probability upon evaluation = 4/48 = 1/12.
The theoretical probability upon evaluation = 1/8.
Consequently, it follows that the experimental probability is less than the theoretical probability by more than 2%.

One painter can paint a room in 2 hours; another painter requires 4 hours to paint
the same room. How long will it take them to paint the room together
Answer:
[tex]1\frac{1}{3}[/tex] hours
Step-by-step explanation:
The first painter does [tex]\frac{1}{2}[/tex] (aka [tex]\frac{2}{4}[/tex]) the job in 1 hour.
The second painter does [tex]\frac{1}{4}[/tex] the job in 1 hour.
This means together they can do [tex]\frac{3}{4}[/tex] the job in 1 hour.
This means to do [tex]\frac{1}{4}[/tex] of the job they will need [tex]\frac{1}{3}[/tex] hours. (third of the work they do in an hour means they need a third of the time)
This means they need [tex]1\frac{1}{3}[/tex] hours to paint the room together.
If you add Natalie's age and Fred's age, the result is 43. If you add Fred's age to 4 times Natalie's age, the result is 88. Write and solve a system of equations to find how old Fred and Natalie are.
Natalie's age = n
Fred's age = f
n + f = 43
4n + f = 88
f = 43 - n
4n + (43 - n) = 88
3n + 43 = 88
3n = 45
n = 15
f = 43 - n
f = 43 - 15
f = 28
Natalie is 15
Fred is 28

What is a function?An expression which defines the relationship between two variables (one independent and one dependent variable).
What is dependent and independent variable?The independent variable is the variable being controlled in the problem, and the dependent variable is the variable that changes with the change of independent variable.
What is inverse of a function?A function that undoes the original function is called the inverse function.
How to find the inverse of y=7x+3 ?To find the inverse function of a given function,
first we will have to interchange the variablesIn the problem,
y is the independent variable x is the dependent variabley=7x+3
To find the inverse
x = 7y + 3 ( interchanging the variables )
Now finding the value of y,

Answer:
alA, C, E would all be correct
Step-by-step explanation:
the explanation is quite simple just put them all together they all come out to 280.
Answer:
A, C, E
Step-by-step explanation:
If we separate 35 into tens and units then:
8 × 35 = 8 × (30 + 5)
We can use the distributive property to expand the above:
8 × (30 + 5) = (8 × 30) + (8 × 5)
We can also separate 35 into 20 + 15:
8 × 35 = 8 × (20 + 15)
Therefore, the expressions that are equal to 8 × 35 are A, C and E
Two cards are drawn without replacement from a standard deck of 52 playing cards. What is the probability of choosing a face card for the second card drawn, if the first card, drawn without replacement, was a king? Express your answer as a fraction or a decimal number rounded to four decimal places.
The decimal value is approximate.
==========================================================
Explanation:
The face cards are Jack, Queen, King.
We have 3 face cards for each suit, and 4 suits, giving 3*4 = 12 face cards out of a 52 card deck.
The first card is a king, which is not put back. This means have 12-1 = 11 face cards left out of 52-1 = 51 cards left.
The probability of getting another face card is 11/51 = 0.2157 approximately
This is about a 21.57% chance
Note: if the first card was put back, or replaced with an equal copy, then the answer would be 12/52 = 3/13 = 0.2308 = 23.08%
Answer:
The probability of choosing a face card for the second card drawn if the first card was a king, drawn without replacement, is 11/663 or .0166.
Step-by-step explanation:
There are 52 cards and 12 of these are face cards.
The probability of drawing a king for the first card is the number of kings divided by the total number of cards:
4/52The probability of drawing a face card after the first card was drawn without replacement is:
11/51When we take the king card out of the deck, we remove 1 from both the denominator and the numerator since it is also a face card.Since these events are dependent (drawing without replacement), we can use this basic probability formula:
[tex]P(A \cap B)=P(A) \cdot P(B)[/tex]This formula tells us the probability of first drawing the king card, then drawing a face card afterward since 2 cards are being drawn. We must calculate the probability of both of these events occurring one after the other.
P(A) refers to the probability of getting a king on the first draw, 4/52, and P(B) refers to the probability of getting a face card on the second draw, 11/51.
Let's multiply these probabilities together.
[tex]\displaystyle \frac{4}{52} \cdot \frac{11}{51} =\frac{11}{663}=.0166[/tex]The probability of choosing a face card for the second card drawn, if the first card drawn without replacement was a king, is 11/663 or .0166.

Answer:
16.12 mi²
Step-by-step explanation:
The formula for the area of a trapezoid is A = 1/2h([tex]b_{1} +b_{2}[/tex]), where [tex]b_{1}[/tex] stands for base 1, and [tex]b_{2}[/tex] represents base 2. Plugging in the given values, we have A = 1/2(3.1)(8.3 + 2.1). Now we can solve.
------------------------------
A = 1/2(3.1)(8.3 + 2.1)
1/2(3.1)(10.4)
1.55(10.4)
