Out of the 20 students in Mrs. Green's class, 13 have a pet. What percent of the students in Mrs. Green's class have a pet? The percent of students in Mrs. Green's class that have a pet is

So the minimum probability that a Yes respondent exercises for at least 1 hour is 6/(x+6), where x is the number of students who answered No.

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 indicating an impossible event and 1 indicating a certain event. The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Probability is used in various fields such as mathematics, statistics, science, economics, and finance to model and analyze uncertain situations.

Here,

Let the number of students who answered No be x. Then the number of students who answered Yes is x+12. The total number of students is then x + (x+12) = 2x + 12.

Suppose y of the students who answered Yes exercise for at least 1 hour. Then the probability that a Yes respondent exercises for at least 1 hour is y/(x+12).

Since we don't have the full frequency tree, we can't determine y or x directly. However, we do know that the total number of students who exercise for at least 1 hour is greater than or equal to 12 (since there are 12 more Yes respondents than No respondents). Therefore, the probability that a Yes respondent exercises for at least 1 hour is y/(x+12) is at least 12/(2x+12) = 6/(x+6).

Answer:

Step-by-step explanation:

So the diagram shows the weight of each puppy in pounds.

Each dot is a puppy.

The first dot is at 1/4 pounds meaning you have one dog that weights that much.

At the other end, you have 3 dots at 3/4 pounds meaning you have one dog that weights that much.

The heaviest puppy is 3/4 and the lightest is 1/4.

So dividing 3/4 / 1/4 = 3/4 * 4 = 3.

So 3 times as great

Answer:

3

Step-by-step explanation:

1/4 x 3 = 3/4

If the 3 times of total number of adults was 17 less than number of children who visited the petting zoo , then the equation to model this relationship is written as c = 3a + 17   ;

let the number of children in the petting zoo be = c ;

and the number of adults in the petting zoo is = a ;

given that the the number of children are 3 times the number of adults ;

that means ⇒ c = 3a ;

and also given that the difference between the number of children and number of adults is 17 .

This situation can be represented as :

⇒ c - 3a = 17 ;

⇒ c = 3a + 17 .

Therefore , the equation to model this relationship is "c = 3a + 17" .

Both sequences are geometric

Step-by-step explanation:

because both have common differences of 2 times

Answer:

4.1, 8.2, 16.4, 32.8,... is a geometric sequence.

Step-by-step explanation:

Given the first sequence

18, 36, 54, 72,...

we know that the geometric sequence is the sequence that has the same common ratio 'r' (constant ratio).

Computing the ratios of all the adjacent terms:

\(\frac{36}{18}=2,\:\quad \frac{54}{36}=1.5,\:\quad \frac{72}{54}=1.33333\dots\)

As the ratio is not constant.

Hence, 18, 36, 54, 72,... is NOT the geometric sequence.

Given the second sequence

4.1, 8.2, 16.4, 32.8,...

we know that the geometric sequence is the sequence that has the same common ratio 'r' (constant ratio).

Computing the ratios of all the adjacent terms:

\(\frac{8.2}{4.1}=2,\:\quad \frac{16.4}{8.2}=2,\:\quad \frac{32.8}{16.4}=2\)

As the ratio of all the adjacent terms is the same (constant ratio).

Hence, 4.1, 8.2, 16.4, 32.8,... is a geometric sequence.

Therefore, 4.1, 8.2, 16.4, 32.8,... is a geometric sequence.

Answer:

1 picnic table : 9 benches

Step-by-step explanation:

You just simplify the equation down to its simplest form, so since they both have the gcf of 6, you divided both sides by 6, which results in the answer above.

Given:

The first equation of the system of equations is

\(5x+2y=-4\)

To find:

The equation that gives a system with no solution.

Solution:

We have,

\(5x+2y=-4\)

It can be written as

\(2y=-5x-4\)

\(y=\dfrac{-5x-4}{2}\)

\(y=-\dfrac{5}{2}x-2\)

On comparing this equation with slope intercept form \(y=mx+b\), we get

\(m=-\dfrac{5}{2},b=-2\)

It means the slope of the line is \(-\dfrac{5}{2}\) and the y-intercept is -2.

Slope of parallel lines are same but the y-intercepts are different.

From the given options, the slope of the line is \(-\dfrac{5}{2}\) only in option D and the y-intercept is -3 which is different from -2.

The line \(y=-\dfrac{5}{2}x-3\) is parallel to the given line and parallel lines have no solution. So, the second equation of the system of equations is \(y=-\dfrac{5}{2}x-3\).

Therefore, the correct option is D.

To solve this problem, we can use the formula for circular permutations: (n-1)!/d, where n is the total number of people and d is the number of ways in which they can be distinguished. In this case, n is 11 (5 democrats + 5 republicans + 1 independent) and d is 1 (since all the members of each party sit together, they are not distinguishable from one another).

The mode is one of the measures of central tendency in statistics. It represents the number that appears most frequently in a given list of numbers. In the example above, the mode for the list of numbers {5, 9, 12, 11, 12, 19, 18} is 12.

The mode is defined as the number that occurs most frequently in a list of numbers. In a set of numbers, there can be one mode, more than one mode, or no mode at all.

To find the mode for the list of numbers {5, 9, 12, 11, 12, 19, 18}, we need to identify the number that appears most frequently. Here, we can observe that 12 is the number that appears twice, while all the other numbers only appear once.

Therefore, the mode for this list of numbers is 12. It's important to note that if there are multiple numbers that appear with the same highest frequency, then all of them are considered as modes. For instance, if the list of numbers was {5, 9, 12, 11, 12, 19, 19, 18}, then both 12 and 19 would be modes since they each appear twice.

In conclusion, the mode is one of the measures of central tendency in statistics. It represents the number that appears most frequently in a given list of numbers. In the example above, the mode for the list of numbers {5, 9, 12, 11, 12, 19, 18} is 12.

The number of individuals who took the quiz is D) 21.

To determine the total number of individuals who took the quiz (N), we need to sum up the frequencies (f) in the given frequency distribution. The frequency (f) represents the number of individuals who obtained each score.

Let's add up the frequencies:

6 + 5 + 5 + 3 + 2 = 21

The total frequency is 21, which means that 21 individuals took the quiz. Each score represents a certain number of individuals who obtained that score, and by adding up all the frequencies, we get the total number of individuals.

The image is formed behind the mirror, and the image is upright.

Given data: Object height, h = 3.0 cm Image distance, v = ? Object distance, u = -20.0 cmFocal length, f = -60.0 cmUsing the lens formula, the image distance is given by;1/f = 1/v - 1/u

Putting the values in the above equation, we get;1/-60 = 1/v - 1/-20

Simplifying the above equation, we get;v = -40 cm

This negative sign indicates that the image is formed behind the mirror, as the object is placed in front of the mirror.

Hence, the image is virtual and erect. Using magnification formula;M = -v/uWe get;M = -(-40) / -20M = 2Hence, the height of the image is twice the height of the object.

The height of the image is given by;h' = M × hh' = 2 × 3h' = 6 cm Now, let's draw the ray diagram:

Total cost = VC(80) + Fixed cost = 1325.34 + 200 = $1525.34

To find the total cost of producing 80 barstools, we need to calculate the variable cost and add it to the fixed cost.

First, integrate the marginal cost function to find the variable cost function:

VC(x) = ∫\((20 - 0.5\sqrt{x dx} )\)

VC(x) = \(20x - (1/3)x^(^3^/^2^) + C\)

The constant C is irrelevant in this case, as we are interested in the difference between VC(80) and VC(0).

Now, evaluate the variable cost function at x = 80:

VC(80) = 20(80) - \((1/3)(80^(^3^/^2^))\)

VC(80) = 1600 - \((1/3)(80\sqrt{80} )\)

VC(80) ≈ 1325.34

Finally, add the fixed cost:

Total cost = VC(80) + Fixed cost = 1325.34 + 200 = $1525.34
