Answer:

20

Step-by-step explanation:

500 divided by 25=20

The required inequality is 500 + 25x ≥ y which represents the given situation.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Let x be the number of days Jayla buys stickers.

The total number of stickers Jayla has at the end of the month is 500 + 25x.

To represent the inequality that Jayla wants at least y stickers in her collection at the end of the month, we can write:

500 + 25x ≥ y

This inequality states that the total number of stickers Jayla has (500 + 25d) is greater than or equal to the number of stickers she wants (y) at the end of the month.

It gives the minimum number of days Jayla should buy stickers to achieve her goal.

Answer:

\(f(-2) = -20\)

Step-by-step explanation:

Plug -2 into the function for x.

\(f(x) = 7x - 6\)

For \(x=-2\):

\(f(-2) = 7(-2) - 6\)

\(f(-2) = -14 - 6\)

\(f(-2) = -20\)

Answer:

Step-by-step explanation:

To solve an equation, we can only have one variable. In this case, we are given the system 2x = 5y + 14. However, we are given the value of x in terms of y. We can substitute 10y in for 2x and solve.

10y = 5y + 14

First, we need to get all the variables on one side of the equation, so we subtract 5y.

5y = 14

Divide by 5

y = 14/5 or 2 4/5 or 2.8

Now for the x part.

2x = x + 14

Subtract 1x

x = 14

Now we check our answer.

2(14) = 5(2.8) + 14

28 = 14 + 14

28 = 28

Because 28 equals 28, our solutions are correct.

Answer:  He is not correct. The resulting will be in a different quadrant.

Step-by-step explanation:  This would be much easier to answer with a screen shot of the image.

For example, if the original image is in quadrant 1, the first reflection over the x-axis places the new image in quadrant 4, "upside-down" and the second reflection over the y=x line places the new image in quadrant 2 and "oblique" to the original.

The answer is "\(5x+10y+5z\)"

Step-by-step explanation:

Given value:

Using the distributive property.

If there are three integers a,b and c then:

\(a \cdot(b+c) =a \cdot b + a \cdot c\)

\(\to \frac{1}{2}(10x) +\frac{1}{2}(20y+10z)\\\\\to (5x) +\frac{1}{2}(20y+10z)\)

Again apply the distributive property

Or

\(\to \frac{1}{2}(10x + 20y +10z)\)

After four hours, the height of the candles will be the same.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

A red candle has an 8-inch height and burns at a 7/10-inch per hour rate. A 6-inch tall blue candle burns at a rate of 1/5 inch per hour.

Let x be the number of hours and y be the height.

y = -0.70x + 8           ...1

y = -0.20x + 6             ...2

From equations 1 and 2, then we have

- 0.20x + 6 = - 0.70x + 8

(0.70 - 0.20)x = 8 - 6

0.50x = 2

x = 4 hours

After four hours, the height of the candles will be the same.

Answer:

5/15 is the probability of choosing a red marble from the box.

Step-by-step explanation:

We know that,

There are 5 red marbles and 10 green marbles in the box.

Divide the number of events by the number of possible outcomes. This will give us the probability.

P(red marble) = P(5)

Possible outcomes

5 red, 10 green -> 15 possibilities

Probability = \(\frac{5}{15}\)

Please leave a 'thanks' if this helped!

The required probability of drawing a red marble the 6th time is 1/2.

Given that,

A box contains 10 red marbles and 10 green marbles.

Sampling at random from this box five times without replacement, you have drawn a red marble all five times.

Without replacing any of the marbles.

We have to determine,

What is the probability of drawing a red marble the 6th time?

According to the question,

There are 10 red marbles and 10 green marbles,

The initial condition is to the same state at every step, so the probability to get a red marble is the same in each sampling  and is equal to the ratio of the number of red marbles to the total number of samples.

Therefore,

The probability of drawing a red marble the 6th time is,

\(P = \dfrac{10}{10+10}\\\\P = \dfrac{10}{20}\\\\P = \dfrac{1}{2}\)

Hence, The required probability of drawing a red marble the 6th time is 1/2.

Step-by-step explanation:

The types of concurrent constructions that are needed to find the centroid of a triangle include the following: B. intersection of the lines drawn to the midpoint of each side of the triangle to its opposite vertex.

In Mathematics and Geometry, the centroid theorem states that the centroid of a triangle is located at two-third (2/3) of the distance from the vertex to the midpoint of the (opposite) sides.

Generally speaking, the centroid of a triangle simply refers to the point where the three (3) medians of the triangle meet or intersect. This ultimately implies that, a centroid is a point of intersection of the lines from each vertex of a triangle to the midpoint of the opposite sides.

In this context, the types of concurrent constructions would be modeled by answer option B.

To find the optimal solution, we need to determine the feasible region by graphing the given constraints and identify the corner points where the constraints intersect. However, to provide a numerical solution, we can use a linear programming solver.

Using a linear programming solver, we can input the objective function C = 7x + 9y and the constraints 6x + 8y ≤ 15 and 9x + 8y ≤ 19, along with the non-negativity constraints x ≥ 0 and y ≥ 0. The solver will then calculate the optimal values of x and y that maximize the objective function C.

The optimal values of x and y will depend on the specific values of the constraints, and the resulting values may not be whole numbers. Therefore, rounding the answers to three decimal places will provide the desired level of precision. The linear programming solver will provide the optimal values of x and y that maximize the objective function C.

The left boundary of the confidence interval in question 1 depends on the specific data and confidence level used to calculate it. In general, the left boundary represents the lower limit of the range of values within which we can be confident that the true population parameter falls. The confidence interval is calculated by taking the point estimate of the parameter, such as the sample mean or proportion, and adding and subtracting a margin of error based on the standard error and the desired level of confidence. The left boundary will be further from the point estimate than the right boundary and will decrease as the level of confidence increases.

Jason's trip was 9 minutes longer than his usual drive to work.

Given that,

Distance from Jason's home to office = 20 miles

Speed of driving from home to office = 50 miles/hour

Total time taken to reach from home to office = distance ÷ speed = 20/50 = 0.4 hours = 24 minutes

Thus, on a normal day, Jason takes 0.4 hours to reach his office from home.

Now, Jason drove for 12 minutes when his car broke down,

The taxi arrived 15 minutes later and drove at 40 miles/hour,

Total time spent to reach office from taxi= distance ÷ speed = 20/40 = 0.5 hours= 30 minutes

Although he already spent 12 minutes driving before the taxi arrived so,

30 - 12 = 18 minutes.

But, he waited for the taxi to arrive for 15 minutes so,

18+15 = 33 minutes.

The annual tax revenue in City B in 2000 was $578,000.

From the graph, we can see that City B experienced a percent change of -28% from 1990 to 1995 and a percent change of -32% from 1995 to 2000

To find the annual tax revenue in City B in 2000, we start with the revenue in 1990, which is given as $800,000.

First, we calculate the tax revenue after the percent change from 1990 to 1995:

Revenue in 1995 = $800,000 + (-28% of $800,000) = $800,000 - $224,000 = $576,000

Next, we calculate the tax revenue after the percent change from 1995 to 2000:

Revenue in 2000 = $576,000 + (-32% of $576,000) = $576,000 - $184,320 = $391,680
