Answer:
Experimental probability is the result of an experiment. Theoretical probability is what is expected to happen. Three students tossed a coin 50 times individually.
Step-by-step explanation:
Experimental probability is found through experiments while theoretical probability are not.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
Theoretical probability is the probability that we use normally which describes the percent or probability that an event is likely to happen. This is found using logic.
Experimental probability is the probability that we calculate through the actual experiments that describes the frequency of an event happening. This is found using experiments which are repeated.
They can be same, both of which describes the probability of happening an event.
Hence the experimental probability is found through experiments while theoretical probability are not.

Let O be a quadrant I angle with cos(0) ✓11/7 Find sin(20).
Answer:
[tex]\displaystyle \sin(2\theta)=\frac{2\sqrt{418}}{49}\approx0.8345[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \cos(\theta)=\frac{\sqrt{11}}{7}[/tex]
Where θ is in QI.
And we want to determine sin(2θ).
First, note that since θ is in QI, all trig ratios will be positive.
Next, recall that cosine is the ratio of the adjacent side to the hypotenuse. Therefore, the adjacent side a = √(11) and the hypotenuse c = 7.
Then by the Pythagorean Theorem, the opposite side to θ is:
[tex]b=\sqrt{(7)^2-(\sqrt{11})^2}=\sqrt{49-11}=\sqrt{38}[/tex]
So, with respect to θ, the adjacent side is √(11), the opposite side is √(38), and the hypotenuse is 7.
We can rewrite as expression as:
[tex]\sin(2\theta)=2\sin(\theta)\cos(\theta)[/tex]
Using the above information, substitute. Remember that all ratios will be positive:
[tex]\displaystyle =2\Big(\frac{\sqrt{38}}{7}\Big)\Big(\frac{\sqrt{11}}{7}\Big)[/tex]
Simplify. Therefore:
[tex]\displaystyle \sin(2\theta)=\frac{2\sqrt{418}}{49}\approx0.8345[/tex]

Suppose that P dollars in principal is invested in an account earning 2.1% interest compounded continuously. At the end of 2 yr, the amount in the account has earned $193.03 in interest.
A) Find the original principal.
B) Using the the original principal from part (a) and the model A = Pe", determine the time required for the investment to reach $6000.
Answer:
See explanation
Step-by-step explanation:
Recall that
Amount = Principal + Interest
The formula is;
A = P(1 + r)^n
Where;
P= principal, n = time and r = rate
Hence;
P + I = P(1 + r)^n
P + 193.03 = P(1.021)^2
P + 193.03 = 1.04P
P - 1.04P = - 193.03
-0.04 P = - 193.03
P = 193.03/0.04
P = $ 4825.75
B) When A = $6000, n=?
From;
A= P(1 + r)^n
6000 = 4825.75 (1.021)^n
6000/4825.75 = (1.021)^n
1.24 = (1.021)^n
Taking logarithm of both sides;
log 1.24 = n log 1.021
n = log 1.24/log 1.021
n = 0.0934/0.009
n = 10 years

Answer:
48m²
Explanation:
since 3cm represents 4m, the width of the dining hall would be 4m. its length on the drawing is 9cm, which is 3 times of 3cm, so we can also multiply 4m by 3 to find the real length of the dining hall. this would give us 12m.
3cm : 4m
(multiply both by 3)
9cm : 12m
now, we can calculate the area of the dining hall using the equation 12m × 4m = 48m².

Aaron is designing a party game in which he needs exactly 24 possible outcomes. Which sets of actions can he use to have a statistically fair
game?
Answer:
Counting from the top:
fist option
fourth option
fifth option.
Step-by-step explanation:
Any set that has a multiplicative outcome, such that the total number of outcomes is 24.
Remember that if we have a combination of two events, one with N outcomes and the other with M outcomes, the total number of outcomes is:
M*N
This is the main thing we need to see.
Let's analyze each option:
1) flip a coin (2 outcomes)
flip a coin again (2 outcomes)
roll a 6 sided dice ( 6 outcomes)
total number of outcomes:
2*2*6 = 24
2) Selecting a number from 1 to 16 (16 outcomes) and rolling a dice of 8 sides (8 outcomes).
The total number of outcomes is:
8*16 = 128
We wanted only 24.
3) Selecting a number from the set {1, 3, 5, 7, 9} (5 outcomes)
flip a coin (2 outcomes)
flip the coin again (2 outcomes)
total number of outcomes:
2*2*5 = 20
We wanted 24, we can discard this.
4) Spin the thing (3 outcomes)
roll an 8-sided dice (8 outcomes)
Total number of outcomes:
8*3 = 24
This is a correct option.
5) Select a card from A to D (4 outcomes)
Roll the thing (6 outcomes)
total number of outcomes:
6*4 = 24
This is a correct option.
6) Select a card from A to N {14 options}
Roll the thing once (10 outcomes)
Total number of outcomes:
14*10 = 140
We wanted 24, so we can discard this option.
Then the correct options are:
first one, fourth one, and fifth one.
How are translations and reflections represented as a function?
will give brainly and everything
Answer:
Step-by-step explanation:
A vertical reflection is given by the equation y=−f(x) and results in the curve being "reflected" across the x-axis. A horizontal reflection is given by the equation y=f (−x) and results in the curve being "reflected" across the y-axis. You can see that the reflections are presented in the terms of a function.
As for translations, the function would just increase or decrease based on the translations.
In translation the graph of function moves certain distance and in reflection the graph of function reflected along the axis of reflection.
What is translation?"It is a transformation in which the graph of function is moved from one location to another location without changing its size, shape or orientation."
What is reflection?"It is a transformation in which the graph of function is reflected along the line of reflection."
What is function?"It defines a relation between input and output values"
Consider a function f(x).
Translations in function f(x):
1) When function f(x) is transformed to f(x) + k, it means function f(x) is translated vertically up by 'k' units.
2) When function f(x) is transformed to f(x) - k, it means function f(x) is translated vertically down by 'k' units.
3) When function f(x) is transformed to f(x + k), it means function f(x) is translated horizontally left by 'k' units.
4) When function f(x) is transformed to f(x - k), it means function f(x) is translated horizontally right by 'k' units.
Now consider reflections in function f(x):
1) When function f(x) is transformed to -f(x) , it means function f(x) is reflected over X-axis.
2) When function f(x) is transformed to f(-x) , it means function f(x) is reflected over Y-axis.
Therefore, in translation the graph of function moves certain distance and in reflection the graph of function reflected along the axis of reflection.

A hotel restaurant has a 75% customer approval rating for its service. The restaurant has a 60% customer approval rating for its service and its food. What is the probability that a restaurant customer approves of the food if he or she approves of the service?
The probability that a restaurant customer approves of the food given that they already approved of the service is 0.8, or 80%.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Let's use Bayes' theorem to solve this problem.
= P(approves of food | approves of service)
By Bayes' theorem, we can express this probability in terms of the probabilities of approving of the service and the food separately:
P(approves of food | approves of service) = P(approves of service and food) / P(approves of service)
We know that the overall customer approval rating for the service is 75%, so:
P(approves of service) = 0.75
We also know that the customer approval rating for both the service and the food is 60%, so:
P(approves of service and food) = 0.60
Substituting these values into the formula, we get:
P(approves of food | approves of service) = 0.60 / 0.75
P(approves of food | approves of service) = 0.8
Therefore, the probability that a restaurant customer approves of the food given that they already approved of the service is 0.8, or 80%.

The median of these numbers is
how much less than the mean?
1.5, 0.6, 0.7, 0.85, 5.3
Answer:
The median of the numbers is 3.66 less than the mean
Step-by-step explanation:
To find the median, find the middle of the numbers
0.6, 0.7, 0.85, 1.5, 5.4
To find the mean, add all the numbers and divide by the number of numbers
0.6 + 0.7 + 0.85 + 15 + 5.4 = 22.55
22.55/5 = 4.51
To find how less, subtract the median from the mean
4.51 - 0.85 = 3.66
