20% of the students voted for the athlete

Step-by-step explanation:

The proportion of students who voted for athlete is the number of students who voted for the athlete divided by the total number of students.

The percentage is the proportion multiplied by 100.

We have that:

20 students voted for the athlete.

Total of 100 students.

20/100 = 0.2

0.2*100 = 20%

20% of the students voted for the athlete

Answer:

The area of triangle PQR which has a base of 86 inches and a height of 52 inches is 2,236 square inches.

The area of the triangle is the space occupied by it on the two-dimensional plane. The area of the triangle is half of the product of its base and height.

Answer:

factored is (x+1)(x+5)

Step-by-step explanation:

gradpoint

The binomials (x + 1) and ( x + 5 ) are factors of the quadratic expression of x² + 6x + 5.

Given the quadratic expression in the question:

x² + 6x + 5

To find the binomials that are factors of the quadratic expression x² + 6x + 5, we have to factorize the quadratic expression.

The binomials will be in the form of (x + a)(x + b).

x² + 6x + 5

Now, factorizing the expression,  consider a pair of integers, "a" and "b," such that their sum is 6 and their product is 5.

The integers that satisfy these conditions are 1 and 5.

Hence, plug them in:

(x + a)(x + b)

( x + 1 )( x + 5 )

Therefore, the factors of the expression are ( x + 1 ) and ( x + 5 ).

The probability of drawing two red marbles is approximately 16.7%.

To find the probability of drawing two red marbles from the bag, we need to find the probability of drawing one red marble and then, given that the first marble was red, drawing another red marble. The probability of drawing a red marble on the first draw is 4/9 (since there are 4 red marbles out of a total of 9 marbles). After the first marble is drawn, there are now 8 marbles left in the bag, including 3 red marbles.

Therefore, the probability of drawing a red marble on the second draw, given that the first marble was red, is 3/8. To find the probability of both events occurring, we multiply the probabilities: (4/9) × (3/8) = 1/6, or approximately 16.7%.

The probability of drawing 2 red marbles without replacement from a bag containing 4 red, 3 blue, and 2 green marbles is 16.7%.

The question is asking for the probability of drawing two red marbles from a bag that contains 4 red marbles, 3 blue marbles, and 2 green marbles, without replacing the first one drawn.

Firstly let's figure out the total number of ways to draw 2 marbles from a bag of 9 marbles. Using combination formula, the total number of possible ways is: 9C2 = 36.

Now, how many ways can you draw 2 red marbles from 4? That will be: 4C2 = 6 ways.

So the probability of drawing 2 red multiplies, without replacement, is therefore 6 / 36 = 0.167 or 16.7% when rounded to the nearest tenth of a percent.

Final answer:

The number of bulls in a herd with a bull-to-cow ratio of 1:6 is one-seventh of the total number of animals in the herd, represented as x/7.

Explanation:

In the scenario where the ratio of the number of bulls to cows is 1:6, we can express the number of bulls in terms of x, where x represents the total number of animals in the herd.

Let's define the number of bulls as B and the number of cows as C. Given the ratio B:C = 1:6, for every 7 animals in the herd (1 bull + 6 cows), there is 1 bull.

To find the number of bulls in terms of x, we divide the total number of animals by the sum of the parts of the ratio (1+6=7). So, the formula to find the number of bulls (B) is:

B = x / 7

Therefore, if x is the total number of animals in the herd, the number of bulls is one-seventh of x.

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%.

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).

A cube is a three-dimensional representation of a square. it has 6 faces 2 on the bottom and top, 4 on the sides faces.

We are given that Eliana has two different cube-shaped packing boxes.

Since first box has a surface area of 384 in.2, and the second box has a surface area of 6,144 in.2.

Then the surface area of first box = 6( edge)^2

384 = 6 x ( edge)^2
