Is 57 a prime number

Answer:

No he doesnt have enough

Step-by-step explanation:

For this case we have the following statement:

Concha is making dresses, if she has made 2/3 of 6 dresses. How many fractions of dresses does she have left to finish? How many dresses have you already made?

If Concha has made [tex]\frac {2} {3}[/tex] of 6 dresses we have:

[tex]\frac {2} {3} * 6 = \frac {6 * 2} {3} = \frac {12} {3} = 4[/tex]

So we have to:

[tex]\frac {3} {3} - \frac {2} {3} = \frac {1} {3}\\6 * \frac {1} {3} = 2[/tex]

Thus, Concha must make 2 dresses to complete all 6. This represents[tex]\frac {1} {3}.[/tex]

Answer:

Concha has made 4 dresses and must make 2 to complete the 6 dresses.

Answer:

n*54/100

Step-by-step explanation:

it depend on your class students number. if your class number is n, n*54/100 is your answer and it must be a natural number so u must rond it. for example if n was 20 so 20*54/100 = 10.8 that must rond it to number 10. 10 is the answer.

54% as a decimal is 0.54. This is found by converting the percent (per hundred) to the fraction 54/100, and then dividing the numerator by the denominator.

To write 54% as a decimal, you need to convert the percent into a fraction and then to a decimal. The word 'percent' means 'per hundred,' so 54% can be written as 54/100. To convert this fraction to a decimal, you divide the numerator by the denominator.

Here's the conversion step by step:

Therefore, 54% as a decimal is 0.54%.. This means that 54% of the students in the class have moved at least one time, which is equivalent to 0.54 when expressed as a

Final answer:

There are 72 possible outcomes in the experiment.

Explanation:

The total number of outcomes for the experiment can be found by multiplying the number of outcomes for each event.

For the first event, rolling a six-sided number cube, there are 6 possible outcomes (numbers 1 to 6).

For the second event, flipping a coin, there are 2 possible outcomes (heads or tails).

For the third event, rolling a six-sided number cube again, there are 6 possible outcomes.

To find the total number of outcomes, multiply the number of outcomes for each event: 6 x 2 x 6 = 72.

Therefore, there are 72 possible outcomes in this experiment.

The point (4,60) on a graph in the context of a bicyclist traveling likely represents that the bicyclist traveled a distance of 60 units in a time of 4 units, where the exact units would depend on the graph's axes' labels.

In go math books page 131, the point (4,60) typically represents a point on a graph or chart. In the context of a bicyclist traveling, the two numbers in the point likely stand for two different values or measurements. The first number '4' could represent time elapsed (for example, 4 hours or 4 minutes) and the second number '60' could possibly represent the corresponding distance traveled by the bicyclist (for example, 60 miles or 60 meters). Therefore, the point (4,60) could mean that the bicyclist traveled a distance of 60 units in a time of 4 units. The exact meanings of '4' and '60' would depend on the labels of the x-axis and y-axis of the graph.

The point (4,60) likely represents that after 4 units of time, the bicyclist has traveled 60 units of distance. This is typically used to interpret motion on a distance-time graph in kinematics, which is a branch of physics.

In the context of a Go Math book, the point (4,60) on a graph usually represents two distinct pieces of information about an event or a scenario. For instance, if we're considering the motion of a bicyclist, the point (4,60) might represent that after 4 units of time (such as 4 minutes or 4 hours), the bicyclist has traveled 60 units of distance (such as 60 meters or 60 miles). However, without the specific context or the content of page 131, it's challenging to determine the exact meaning of the point.

In Figure 24.7, which describes the motion of a motorist, time is on the y-axis and distance on the x-axis, which is a common convention for distance-time graphs in motion problems. Therefore, if (4,60) were a point on such a graph, 4 would likely represent the time elapsed and 60 the distance traveled.

Understanding points on these graphs helps students to visualize and interpret different aspects of motion, such as speed, displacement, and acceleration, contributing greatly to their grasp of kinematics of physics

Step-by-step explanation:

The Ortega family has 11/16 pound of confetti left for next year's fiesta after using 1/4 pound this year.

The Ortega family started with 15/16 pound of confetti for the celebration. They used 1/4 pound of confetti for the fiesta eggs. To find out how much confetti they have left, we need to subtract the amount used from the total amount they made.

To subtract these fractions, they need to have the same denominator. The fractions already have the same denominator here, which makes it simpler. So, we subtract 1/4 from 15/16:

Therefore, the Ortega family has 11/16 pound of confetti left for the next year's celebration.

[tex]x-y\leq 1[/tex] ----> inequality B

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities of the system (makes true both inequalities)

Verify each ordered pair

Substitute the value of x and the value of y of each ordered pair in the inequality A and in the inequality B and then compare the results

case 1) (0,5)

For x=0,y=5

Inequality A

[tex]2(0)+3(5) > 12[/tex]

[tex]15 > 12[/tex] ----> is true

so

The ordered pair satisfy inequality A

Inequality B

[tex]0-5\leq 1[/tex]

[tex]-5\leq 1[/tex] ---> is true

so

The ordered pair satisfy inequality B

therefore

The ordered pair would be a solution of the system

case 2) (5,2)

For x=5,y=2

Inequality A

[tex]2(5)+3(2) > 12[/tex]

[tex]16 > 12[/tex] ----> is true

so

The ordered pair satisfy inequality A

Inequality B

[tex]5-2\leq 1[/tex]

[tex]3\leq 1[/tex] ---> is not true

so

The ordered pair not satisfy inequality B

therefore

The ordered pair is not a solution of the system

case 3) (0,4)

For x=0,y=4

Inequality A

[tex]2(0)+3(4) > 12[/tex]

[tex]12 > 12[/tex] ----> is not true

so

The ordered pair not satisfy inequality A

therefore

The ordered pair is not a solution of the system

For x=6,y=0

Inequality A

[tex]2(6)+3(0) > 12[/tex]

[tex]12 > 12[/tex] ----> is not true

Answer:

Biased; conveince sample response.

Explanation:

THE HOMEROOM might have the sam intrests for the theme

The sampling method most likely to result in self-selection bias is the voluntary response sample. It involves individuals choosing to respond to the survey and may result in a biased sample as those who participate may not represent the overall opinion of the student body.

In the context of the homecoming dance committee's survey, the method that is most likely to result in self-selection bias is the voluntary response sample. This sampling method involves allowing individuals to choose to respond to the survey on their own. The bias comes from the fact that those who choose to respond may not be representative of the entire student body due to differences in interest or motivation related to the theme of the dance. For example, students with strong opinions on the theme or are more involved in the dance may be more likely to respond, leading to a self-selected and therefore potentially biased sample.

1x + 2y = (The answer/money spent)

The total cost that Rahmi spent can be represented by an equation c = j + 2t, with 'c' representing the total cost, 'j' the price of jeans, and 't' the price of a T-shirt. Actual costs can't be determined without specific prices.

To figure out how much Rahmi spent, let's set up an equation with the unknown quantities. Let's assume the cost of one pair of jeans is represented by 'j' and the cost of one T-shirt is represented by 't'. Since Rahmi bought 1 pair of jeans and 2 T-shirts, the total cost, 'c', can be represented as:

c = j + 2t

Unfortunately, without specific prices for the jeans and the T-shirts, we cannot calculate the exact total cost. However, this equation will help Rahmi to determine the cost once the prices are known.

Answer:

Step-by-step explanation:

y ∞ 1/x

y = k/x

Where k is the constant of proportionality

When x = 3 and y = 5

5 = k/3

Cross multiply

k = 5×3

k = 15

The equation is y = 15/x

The given relationship Y varies inversely with X and when X is equal to 3, Y equals to 5 which leads us to the equation Y = 15/X which illustrates this inverse variation.

The given question states that Y varies inversely with X and provides us with a pair of values - X = 3, Y = 5. In mathematics, when one quantity Y varies inversely as another X, it can be represented by the equation Y = k/X where k is the constant of variation. To find k, we will substitute the given X and Y values into the equation leading to 5 = k/3. Simplifying, we find k = 5*3, that is, k equals 15. Therefore, the equation that represents this inverse variation is Y = 15/X.
