Answer:

[tex]60 \: degrees[/tex]

Step-by-step explanation:

[tex]180(n - 2)[/tex]

you have to put the number of sides for n

[tex]180(n - 2) \\ 180(6 - 2) \\ 180 \times 4 \\ = 720[/tex]

720 is the sum of interior angles. so to find the value of an angle you have to divide 720 by the number of angles.

[tex] \frac{720}{6} = 120 \: \: degrees[/tex]

we know that,

interior angle + exterior angle = 180 degrees

[tex]120 + z = 180 \\ z = 180 - 120 \\ z = 60 \: \: degrees[/tex]

Answer:

The maximum height of the arrow is 125 feet.

Step-by-step explanation:

The pathway of the arrow can be represented by the equation,

[tex]h = -16t^2 +80t + 25[/tex] .....(1)

Where h is height in in feet and t is time in seconds.

It is required to find the maximum height of the arrow. For maximum height, [tex]\dfrac{dh}{dt}=0[/tex].

So,

[tex]\dfrac{d(-16t^2 +80t + 25)}{dt}=0\\\\-32t+80=0\\\\t=\dfrac{80}{32}\\\\t=2.5\ s[/tex]

Put t = 2.5 s in equation (1). So,

[tex]h = -16(2.5)^2 +80(2.5) + 25\\\\h=125\ \text{feet}[/tex]

So, the maximum height of the arrow is 125 feet.

Answer:

Using a system of equations, however, allows me to use two different variables for the two different unknowns.

number of adults: a

number of children: c

With these variables, I can create equations for the totals they've given me:

total number: a + c = 2200

total income: 4a + 1.5c = 5050

Now I can solve the system for the number of adults and the number of children. I will solve the first equation for one of the variables, and then substitute the result into the other equation:

a = 2200 – c

4(2200 – c) + 1.5c = 5050

8800 – 4c + 1.5c = 5050

8800 – 2.5c = 5050

–2.5c = –3750

c = 1500

Now I can back-solve for the value of the other variable:

a = 2200 – (1500) = 700

I have values for my two variables. I can look back at my definitions for the variables to interpret these values. To answer the original question, there were:

1500 children and 700 adults.

Final answer:

A word problem involving two people and their apples, where Alice has twice as many apples as Bob. The variables are defined, the equation is written, and the solution is found.

Explanation:

Word Problem:

Alice has twice as many apples as Bob. Together, they have 15 apples. Define the variable 'x' as the number of apples Bob has.

Equation:

Alice's apples: 2x

Bob's apples: x

2x + x = 15

Solution:

Combining like terms: 3x = 15

Dividing both sides by 3: x = 5

Sentence Explanation:

We defined the variable 'x' as the number of apples Bob has. Since Alice has twice as many apples, we expressed her number of apples as 2x. The total number of apples they have together is 15, so we created an equation by summing up both Alice's and Bob's apples. By solving for 'x', we found that Bob has 5 apples.

Answer:

Step-by-step explanation:

The probability of getting exactly 1 red marble is 60/121.

Given data:

To find the probability of getting exactly 1 red marble, we need to consider the two possible scenarios:

Getting a red marble on the first draw and a blue marble on the second draw.

Getting a blue marble on the first draw and a red marble on the second draw.

The probability of getting a red marble on the first draw is 5/11, since there are 5 red marbles out of a total of 11 marbles in the bag.

The probability of getting a blue marble on the second draw is also 6/11, since we replace the marble after the first draw, so the number of marbles remains the same.

The probability of the first scenario occurring is (5/11) * (6/11) = 30/121.

Similarly, the probability of the second scenario occurring is (6/11) * (5/11) = 30/121.

To find the total probability of getting exactly 1 red marble, we add the probabilities of these two scenarios:

Total probability = (30/121) + (30/121)

= 60/121.

Hence, the probability of getting exactly 1 red marble is 60/121.

The probability of drawing exactly one red in two draws, considering the order, is the sum of the two scenarios: 'red then blue' and 'blue then red'. Here, the total probability is calculated as (5/11 * 6/11) + (6/11 * 5/11).

The question presented falls under the concept of probability in Mathematics. We have a bag with 6 blue and 5 red marbles. A marble is chosen, its color is recorded, and then it is put back in the bag before another marble is chosen. Thus, the color of the first marble selected does not have any influence on the color of the second marble because of replacement.

To get the probability of drawing one red marble in two attempts, we can consider two possibilities: either the first draw is red and the second is blue, or the first draw is blue and the second is red.

Scenario 1: The first marble drawn is red and the second marble drawn is blue. The probability of drawing a red marble on the first attempt is 5/11, since there are 5 red marbles out of a total of (6+5)=11 marbles. After replacing the first marble, the probability of drawing a blue marble on the second try is 6/11. Therefore, the total probability for this possibility is the product of both individual probabilities: (5/11) * (6/11).

Scenario 2: The first marble drawn is blue and the second marble drawn is red. The probability is calculated in the same manner resulting into (6/11) * (5/11).

Finally, to get the total probability of drawing exactly one red marble in two draws, we add the probabilities for the two scenarios: (5/11 * 6/11) + (6/11 * 5/11).

Answer:

There were 20 questions on the quiz

Step-by-step explanation:

In this question, we are concerned with knowing the number of questions on a quiz, given that Deana had a certain percentage after scoring an amount of marks.

We proceed as follows;

Let the number of questions on the quiz be X.

Now, she got 85% by making 3 incorrect choices. This means the percentage of questions she got incorrectly would be 100-85 = 15%

what we are saying is that it is just 15% of her questions that were wrong.

This mathematically;

15% of x = 3

15/100 * x = 3

15x = 3 * 100

15x = 300

x = 300/15

x = 20

The probability of exactly 1 person favoring the new building project out of 3 people chosen at random is approximately 0.4083, or 40.83%.

Use the concept of probability defined as:

Probability is the ratio of the number of favorable outcomes to the total number of outcomes for the occurrence of an event.

Given that,

A poll was conducted on a new building project.

The results of the poll represent 45% of the respondents were in favor of the new building project.

To calculate the probability that exactly 1 person favoring the new building project out of 3 people chosen at random:

Use the binomial probability formula:

[tex]P(X=k) = (^nC_k) p^k (1-p)^{(n-k)}[/tex]

Where P(X=k) is the probability of getting exactly k favorable responses, and n is the total number of people chosen.

In this case, n = 2,

k is the number of favorable responses, in this case, 1,

p is the probability of an individual favoring the new building project in this case, 0.45,

And (1-p) is the probability of an individual not favoring the new building project in this case, 0.55.

Now substitute the values into the formula:

[tex]P(X=1) = (^3C_1) (0.45^1) (0.55^{(3-1)})[/tex]

Calculating the values:

[tex]^3C_1 = 3[/tex]

(which represents the number of ways to choose 1 favorable response out of 3 people),

[tex]0.55^{(3-1)} = 0.3025.[/tex]

Substituting these values back into the formula:

P(X=1) = (3)(0.45)(0.3025)

Calculating further:

P(X=1) = 0.4083

Hence,

The probability of exactly 1 person favoring the new building project out of 3 people chosen at random is approximately 0.4083, or 40.83%.

Final answer:

The probability of exactly 1 out of 3 individuals favoring a new building project is 40.35%.

Explanation:

The probability of a person favoring a new building project is 45%.

To find the probability that exactly 1 out of 3 chosen individuals favor the project, we use the binomial probability formula:

Calculate the probability of 1 person favoring the project: 0.45 * 0.55 * 0.55 = 0.1345

Calculate the number of ways 1 person can be chosen out of 3: 3 choose 1 = 3

Multiply the two results: 3 * 0.1345 = 0.4035

Therefore, the probability that exactly 1 out of 3 individuals favor the new building project is 0.4035 or 40.35%.

Answer:

Step-by-step explanation:

The information from Satellite Company Y is:

65 people watch live and 94 people watch recorded.

The total number of people from Y is:

65 + 94 = 159

So the probability that a random person from Y watches recorded shows more often is given by the division of the number of people watching more recorded shows (94) over the total number of people (159):

Probability = 94 / 159 = 0.5912 = 59.12%
