To solve the equation -5+1/4x=3x+6 by graphing, rewrite the equation, graph it, and identify where the line crosses the x-axis. This x-coordinate represents the solution. If the line doesn't cross the x-axis, there's no solution.

To solve the equation −5+1/4x=3x+6 by graphing, begin by rewriting the equation as 1/4x − 3x = 6 + 5. This simplifies to -2.75x = 11. Next, graph the equation y = -2.75x + 11 on a coordinate plane.

To find the x-coordinate for the solution, see where the line crosses the x-axis (meaning y = 0). This will give you your solution, which is the value of x that makes the equation true.

However, you may find that graphing the given equation results in a line that does not intersect the x-axis. This means the equation has no solution when y equals to zero.

Answer:

4.46

Step-by-step explanation:

As the circumference of a circle is pi multiplied by the diameter to work out the radius you would first divide the circumference of 28 by pi, which gives you 8.92. This is the diameter, however the question is asking for the radius. To work out the radius you would divide the diameter by 2, which gives you 4.46. This is because the radius is half of the diameter.

1) Divide 28 by pi.

[tex]28/\pi =8.92[/tex]

2) Divide 8.92 by 2.

[tex]8.92/2=4.46[/tex]

Answer:

School ended at 3:20 pm

Step-by-step explanation:

The school ended at the same time as the final bell. We will call this time "x". After 20 minutes the practice began, therefore it began at "x + 20 min" and it lasted for 30 min, therefore it ended at "x + 50 min". She took an additional 15 minutes to get home, therefore she got home at "x + 65 min" or "x + 1h05min". We know that she arrived at 4:25, so:

x + 1:05 = 4:25

x = 4:25 - 1:05

x = 3:20 p.m.

To calculate the sales tax for an $8.00 pillow in Connecticut, convert the 6.35% tax rate to decimal and multiply it with the pillow's price, then round to the nearest cent and add to the original price. The sales tax is $0.51, making the total price $8.51.

To find the sales tax amount and the total price of an $8.00 pillow in Connecticut, with a sales tax rate of 6.35%, follow these steps:

First, convert the percentage to a decimal by dividing by 100. So 6.35% becomes 0.0635.

Next, multiply the pillow's price by this decimal to calculate the sales tax amount. That is $8.00 * 0.0635 = $0.508.

Since you need to round to the nearest penny, round $0.508 to $0.51.

Finally, add the sales tax to the original price to get the total cost. So the total price is $8.00 + $0.51 = $8.51.

The sales tax on an $8.00 pillow is $0.51, and the total price including tax is $8.51.

Answer:

The simulation tool could be a coin flip, with heads up representing a girl and tails up representing a boy. One trial would require flipping the coin twice. One table would show the outcome of two coin tosses as tally marks, and indicate whether the results were boy-boy, boy-girl, or girl-girl.

Final answer:

A simulation to estimate the percentage of two-child families with two girls involves using a random number generator, assigning numbers to represent gender, and conducting repeated trials. By calculating the proportion of simulations resulting in two girls, we can estimate the percentage of such families in the town.

Explanation:

To estimate the percentage of two-child families with two girls in a town of 10,000 such families, a simple simulation could employ a random number generator as the simulation tool. We can model each child as a separate random event with an equal probability of being a girl or a boy, ignoring other complexities such as multiple births or gender selection.

Here is a step-by-step explanation of how the simulation could be designed and conducted:

Assign numbers to represent the outcomes: 1 for a girl and 0 for a boy.

For each simulation, use a random number generator to produce two numbers (each being 0 or 1) to represent the two children in a family.

If both numbers generated are 1, then that simulation represents a family with two girls.

Repeat the simulation 10,000 times, once for each family.

Count the number of simulations that resulted in two girls.

Divide the count of two-girl families by the total number of families (10,000) to get the percentage of families with two girls.

This process would simulate the random assignment of genders in two-child families and allow the estimation of the percentage of families with two girls.

Step-by-step explanation:

The line is a vertical line.

Vertical lines have undefined slopes

Answer:

Undefined

Step-by-step explanation:

Vertical lines will always have undefined slopes. This is a vertical line because it is straight up and down.

To make sure, we can test 2 points: (2,1) and (2,2) in the slope formula

It is impossible to divide by 0, so the slope is undefined.

Step-by-step explanation:

For this question, you would need to figure out how much the total is without the tax.

.2 x 43 = 8.6

After you do that, you would need to find the total with tax.

.07 x 43 = 3.01

Add all of those up.

43 + 8.6 + 3.01 = $54.61

Answer:

gain is $2,704.00

rate of return is 22%

Step-by-step explanation:

The it would take for mutual to double can be determined the future value formula as shown below:

=nper(rate,pmt,-pv,fv)

rate is the rate of return of 7% per year

pmt is the periodic amount placed in the mutual fund and it not applicable here

pv is the original amount invested which is $7,500

fv is the future worth of $15,000

=nper(7%,0,-7500,15000)=10.2 years

cost of shares=actual cost of purchase+broker's commission

                      =(800*$15.34)+$20=$12,292.00  

gain on shares=sales proceeds-cost=(800*$18.77)-$20-$12,292.00=$2,704.00  

rate of return=gain/original cost=$2,704.00/$12,292.00  =22%

The mean, median, and mode of the weekly salaries at the Midtown Construction Company are provided. We can use this information to answer questions about the percentage of salaries surpassing certain values and the total salary of all employees.

To answer the question, we need to understand what each statistical term means.

The mean is the average of a set of numbers. In this case, the mean salary is $620.

The median is the middle value of a set of numbers when they are arranged in ascending order. In this case, the median salary is $610.

The mode is the value that appears most frequently in a set of numbers. In this case, the mode salary is $600.

Now, let's answer the questions:

c. To find the percentage of employees' salaries that surpassed $645, we need to calculate the percentage of values that are greater than $645 in the data set. Since the third quartile is $645, we know that 75% of the salaries are less than or equal to $645. Therefore, about 25% of the salaries surpassed $645.

d. To find the percentage of employees' salaries that surpassed $685, we need to calculate the percentage of values that are greater than $685 in the data set. Since the 85th percentile is $685, we know that 85% of the salaries are less than or equal to $685. Therefore, about 15% of the salaries surpassed $685.

e. To find the total weekly salary of all employees, we need to multiply the mean salary ($620) by the number of employees (100). Therefore, the total weekly salary of all employees is $62,000.
