What is the avantage of using exponential notion?
Answer:
Exponential notion makes a big number easier to write and read.
Step-by-step explanation:
1. An advertising agency finds that of its 200 clients, 150 use television (T), 80 use magazines (M), and 50 use both. a. clients. Use these data to complete a Venn diagram displaying the use of mass media for these 200 b. Use your Venn diagram to determine the following probabilities: i. P(T) ii. P(T^M) iii. P(TUM) P(T|M)
By using Venn diagram the following probabilities are 0.75,0.25,0.9 and 0.625.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
Number of clients= 200
Number of television= 150
Magazines=80
Both magazine and television=50
Now,
To complete the diagram, we can fill in the following values:
The size of T is 150.
The size of M is 80.
The size of TM (the overlap between T and M) is 50.
The size of C (the total number of clients who use either T or M) is 150 + 80 - 50 = 180.
The size of U (the number of clients who use neither T nor M) is 200 - 180 = 20.
Now we can use the Venn diagram to answer the following probabilities:
i. P(T) is the probability that a randomly selected client uses television. This is the size of T divided by the total number of clients, which is 150/200 = 0.75.
ii. P(T ∩ M) is the probability that a randomly selected client uses both television and magazines. This is the size of TM divided by the total number of clients, which is 50/200 = 0.25.
iii. P(T ∪ M) is the probability that a randomly selected client uses either television or magazines (or both). This is the size of C divided by the total number of clients, which is 180/200 = 0.9.
iv. P(T|M) is the probability that a randomly selected client uses television given that they use magazines. This is the size of TM divided by the size of M, which is 50/80 = 0.625.
Therefore, by probability the answer will be 0.75,0.25,0.9 and 0.625.

Step-by-step explanation:
Pedro tracks his steps when he runs. He sets a goal to run exactly 10,000 steps a day on his
running days.
Pedro estimates that there are approximately 2,000 steps in 1 mile. He uses this estimate to
make a plan.
He runs a total of 4 hours over 5 days.
He runs for an equal amount of time each day.
He runs at a rate of 6 miles per hour.
Pedro will not meet his daily running goal with this plan.
What is one change you can make to one value in Pedro's plan to ensure that Pedro meets his
daily running goal? Justify your response.
One change that Pedro can make to his plan to ensure that he meets his daily running goal is to increase the estimated number of steps per mile.
How would this help meet the running goal?If Pedro overestimates the number of steps in a mile, he will end up taking more steps than he initially planned for, which can help him reach his daily goal.
For example, if Pedro increases his estimate from 2,000 steps per mile to 2,500 steps per mile, he will need to run approximately 4 miles per day to reach his goal of 10,000 steps. This will make it more likely for him to reach his daily goal within the 4 hours of running over the 5 days.
Alternatively, Pedro can increase his running speed to cover more distance in a shorter period of time. For instance, if he increases his running speed from 6 miles per hour to 8 miles per hour, he will need to run for only about 2.5 hours per day to reach his goal of 10,000 steps.

The constant percent rate of change per unit interval is approximately 0.0305 or 3.05%.
What is the exponential functions?
An exponential function is a mathematical function of the form:
[tex]f(x) = a^x[/tex]
The given formula for the number of visitors to the county parks system is:
[tex]A = 20.6(1.03)^t[/tex]
where t is the number of years after 2010 and A is the number of visitors in thousands.
To find the constant percent rate of change per unit interval, we can take the derivative of A with respect to t:
[tex]dA/dt = 20.6(1.03)^t * ln(1.03)[/tex]
The constant percent rate of change per unit interval is given by the expression:
r = (dA/dt) / A
Substituting the values of dA/dt and A, we get:
[tex]r = [20.6(1.03)^t * ln(1.03)] / [20.6(1.03)^t]\\r = ln(1.03)\\r = 0.0305[/tex]

For Saturday matinees, a movie theater charges $5 for adult tickets and $3 for children's tickets. If the movie theater sold a total of 166 matinee tickets and made
$718 in revenue on Saturday afternoon, how many adult matinee tickets were sold?
Answer:
Let's use A to represent the number of adult tickets sold and C to represent the number of children's tickets sold.
We know that A + C = 166, since the total number of tickets sold is 166.
We also know that the revenue earned from adult tickets is $5A and the revenue earned from children's tickets is $3C. Since the total revenue earned is $718, we can write:
5A + 3C = 718
Now we have two equations with two variables:
A + C = 166
5A + 3C = 718
We can solve for A in the first equation to get:
A = 166 - C
Then we can substitute this expression for A into the second equation:
5(166 - C) + 3C = 718
Simplifying and solving for C, we get:
830 - 2C = 718
2C = 112
C = 56
So 56 children's tickets were sold. We can substitute this value back into the first equation to solve for A:
A + 56 = 166
A = 110
Therefore, 110 adult tickets were sold.
Answer:
Step-by-step explanation:
Let's use the following variables:
a = number of adult tickets sold
c = number of children tickets sold
We know that:
a + c = 166 (total number of tickets sold)
5a + 3c = 718 (total revenue)
We can solve this system of equations by substitution or elimination. Here, we'll use elimination:
Multiply the first equation by 3: 3a + 3c = 498
Subtract the second equation from the first: 2a = 220
Solve for a: a = 110
So 110 adult tickets were sold. We can find the number of children's tickets by substituting a = 110 into either of the original equations:
c = 166 - a = 166 - 110 = 56
Therefore, 110 adult tickets and 56 children's tickets were sold.

- Make one a rectangular prism that is not a cube.
- Make one a tall triangular prism.
- Make one a trapezoidal prism.
- Make one an octagonal prism.
Explain your thinking for each prism.
Prove that each prism has a volume of 1 dm3
The calculation of volume for the different kind of prisms are:
Rectangular Prism- 1 dm³
Tall triangular prism- 1 dm³
What is Volume?In mathematics, Space occupied by three dimensional objects is called Volume. Basically it is a space within a closed region of every three dimensional object.
Rectangular prism: A rectangular prism that is not a cube can have dimensions of 0.5 dm x 0.5 dm x 4 dm.
This gives a volume of:
0.5 dm x 0.5 dm x 4 dm = 1 dm³
The rectangular prism has six faces, all of which are rectangles.
Tall triangular prism: A tall triangular prism can have a triangular base with sides of length 1 dm, 1 dm, and 2/√3 dm, and a height of 2√3/3 dm. This gives a volume of:
(1 dm x 1 dm x 2/√3 dm) x (2√3/3 dm) = 1 dm³
The tall triangular prism has five faces, one of which is a parallelogram and the other four are triangles.
To prove that each of these prisms has a volume of 1 dm³, we can use the formula for the volume of a prism, which is:
Volume = Base Area x Height
For each of the prisms above, we have calculated the base area and height such that their product equals 1 dm³.
Therefore, each prism has a volume of 1 dm³.

Answer:
Modus Tollens
Step-by-step explanation:
Consider the following argument: If we put all thirty-two volumes of the Encyclopedia Britannica on the top shelf of the bookcase, the bookcase collapses. We do not put all thirty-two volumes of the Encyclopedia Britannica on the top shelf of the bookcase. Hence, the bookcase does not collapse.
The logical form of this argument is Modus Tollens.
Modus Tollens is a mode of argumentation that involves affirming the consequent of a conditional statement. In this argument, the conditional statement is "If we put all thirty-two volumes of the Encyclopedia Britannica on the top shelf of the bookcase, the bookcase collapses." The antecedent of this statement is "we put all thirty-two volumes of the Encyclopedia Britannica on the top shelf of the bookcase," and the consequent is "the bookcase collapses."
Modus Tollens is used to prove the negation of the consequent by negating the antecedent. In other words, if the consequent is not true, then the antecedent must also not be true. Thus, in this argument, since we know that the bookcase does not collapse, we can conclude that we did not put all thirty-two volumes of the Encyclopedia Britannica on the top shelf of the bookcase.
Therefore, the logical form of this argument is Modus Tollens.

According to given conditions:To find the slope of the line of fit, we need to use the formula:
slope = change in y / change in x
In this case, the change in y represents the change in the predicted grade on the test, and the change in x represents the change in the number of hours studied. From the given data, we can see that:
The predicted grade for a student who studies for 0 hours is 80%.
The predicted grade for a student who studies for 1 hour is 90% (80% + 10%).
The predicted grade for a student who studies for 2 hours is 95% (90% + 5%).
Using this information, we can calculate the slope of the line of fit:
slope = (95% - 80%) / (2 hours - 0 hours) = 15% / 2 hours = 7.5%/hour
The slope of the line of fit is 7.5% per hour. This means that for each additional hour a student studies, their predicted grade on the test is expected to increase by an average of 7.5%. The slope represents the rate of change of the predicted grade with respect to the number of hours studied. In this case, a positive slope indicates that there is a positive correlation between the number of hours studied and the predicted grade on the test. The higher the slope, the steeper the line of fit, and the greater the impact of studying on the predicted grade.
Therefore, the slope of the line of fit is 7.5% per hour

The company is searching for a fill amount of 12.305 ounces to identify the highest 1.5% of fill amounts poured by the filling machine.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Given mean of 12.23 ounces and a standard deviation of 0.04 ounces.
To find the fill amount for the highest 1.5% of the fill amounts
we need to find the z-score corresponding to the 98.5th percentile
Using a standard normal distribution table or calculator, we find that the z-score corresponding to the 98.5th percentile is 1.81.
The formula for converting a z-score to a raw score is:
x = μ + zσ
where x is the raw score we want to find, μ is the mean, z is the z-score, and σ is the standard deviation.
x = 12.23 + 1.81(0.04)
x = 12.305 ounces
Therefore, the company is searching for a fill amount of 12.305 ounces to identify the highest 1.5% of fill amounts poured by the filling machine.

If the graph function f (x)=e^x is shifted 6 units to the right what is the equation of the new graph
The equation of the new graph is:
f(x) = e^(x-6)
The graphs of the two functions f(x) = e^x and f(x) = e^(x-6) are shown below
Determining the equation of the new graphFrom the question, we are to determine the equation of the new graph.
If the graph of the function f(x) = e^x is shifted 6 units to the right, the equation of the new graph can be found by replacing x with (x - 6) in the original equation.
This is because a horizontal shift of a function f(x) to the right by c units can be achieved by replacing x with (x - c) in the equation of the function. So, for the given function, a shift to the right by 6 units would be achieved by replacing x with (x - 6) in the original equation f(x) = e^x.
Therefore, the equation of the new graph is:
f(x) = e^(x-6)
This can also be written as:
f(x) = e^x / e^6
