Given:

The graph of linear function.

To find:

The slope intercept form of the linear equation from the given graph.

Solution:

The slope intercept form of a linear function is:

\(y=mx+b\)

From the given graph it is clear that the graph passes through the points (1,300) and (4,800).

The equation of line is

\(y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\)

\(y-300=\dfrac{800-300}{4-1}(x-1)\)

\(y-300=\dfrac{500}{3}(x-1)\)

\(y-300=\dfrac{500}{3}x-\dfrac{500}{3}\)

Adding 300 on both sides, we get

\(y=\dfrac{500}{3}x-\dfrac{500}{3}+300\)

\(y=\dfrac{500}{3}x+\dfrac{900-500}{3}\)

\(y=\dfrac{500}{3}x+\dfrac{400}{3}\)

Therefore, the required equation is \(y=\dfrac{500}{3}x+\dfrac{400}{3}\).

If the data were transformed and points with the coordinates

(x, log(y)) were plotted then the points (1, 1.079), (2, 1.919), (3, 2.763) were plotted.

To plot the points with the coordinates (x, log(y)), we need to take the logarithm of the y-values.

Let's calculate the logarithms for the given data:

x     y            log(y)

1     12          log(12) = 1.079

2     83        log(83) = 1.919

3     580      log(580) = 2.763

Therefore, the points that would be plotted are (1, 1.079), (2, 1.919), (3, 2.763)

The correct option on Hash 1 and Hash 2 is C. Hash 1 is designed to work with small input data, while Hash 2 is optimized for processing large input data.

The main difference between Hash 1 and Hash 2 is the amount of input data they can process. Hash 1 can process input data that is 2 characters long, while Hash 2 can handle input data that is up to 300,000 characters long. This means that Hash 2 is better suited for processing larger datasets than Hash 1.

In terms of which hash function is better suited for different types of data, it depends on the specific application and the characteristics of the data being processed. For example, if the data being hashed is small and of low complexity, Hash 1 may be a good choice due to its speed and simplicity.

Answer:

76.5 hours

(If you like this answer i would appreciate if u give brainliest but otherwise, i hope this helped ^^)

Step-by-step explanation:

Part 1 of 2:

(a) The equation that describes Winona's total take-home pay, P, in terms of the number of hours, x, worked at the first job and the number of hours, y, worked at the second job can be written as:

P = (10x) + (9.25y + 0.7 * 9.25y) - 0.2[(10x) + (9.25y + 0.7 * 9.25y)]

Simplifying the equation:

P = 10x + 9.25y + 0.7 * 9.25y - 0.2(10x + 9.25y + 0.7 * 9.25y)

Part 2 of 2:

(b) If Winona is committed to working 30 hours per week at the first job, let's assume x = 30. We need to find the number of hours per week, y, she would need to work at the second job to reach a biweekly take-home pay of $800.

Using the simplified equation from part (a), we substitute x = 30 and solve for y:

800 = (10 * 30) + (9.25y + 0.7 * 9.25y) - 0.2[(10 * 30) + (9.25y + 0.7 * 9.25y)]

800 = 300 + (9.25y + 0.7 * 9.25y) - 0.2(300 + (9.25y + 0.7 * 9.25y))

Now, we can solve for y:

800 = 300 + 9.25y + 0.7 * 9.25y - 0.2(300 + 9.25y + 0.7 * 9.25y)

Simplify the equation:

800 = 300 + 9.25y + 0.7 * 9.25y - 0.2 * 300 - 0.2 * 9.25y - 0.2 * 0.7 * 9.25y

Combine like terms:

800 = 300 - 60 + 9.25y - 1.85y - 0.1295y

800 = 240 + 7.32y

Subtract 240 from both sides:

560 = 7.32y

Divide both sides by 7.32:

y ≈ 76.5

Therefore, Winona would need to work approximately 76.5 hours per week at her second job to reach a biweekly take-home pay of $800.

To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where A is the ending amount, P is the initial principal, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years.

Plugging in the given values, we have:

A = 2000(1 + 0.086/2)^(2t) = 3178

Dividing both sides by 2000 and taking the natural logarithm of both sides, we get:

ln(1 + 0.086/2)^(2t) = ln(3178/2000)

Simplifying and solving for t, we get:

t = (ln(3178/2000))/[2 ln(1 + 0.086/2)]

Plugging in these values into a calculator, we get:

t ≈ 4.43

Therefore, it will take approximately 4.43 years for the investment to grow to $3178. To check our answer, we can plug this value back into the original equation:

A = 2000(1 + 0.086/2)^(2*4.43) ≈ 3178.01

So the answer is that it will take about 4.43 years for the $2000 investment to grow to $3178 at an annual rate of 8.6%, compounded semiannually.

Answer:

The answer is "There are \(97.5\%\) of the students pass in the test ".

Step-by-step explanation:

Since a normally distributed random variable, the practical rule states:

About 68% of the metrics are in the 1 default deviation

About 95% of metrics correspond to 2 standard deviations from the average.

About 3 standard deviations of the average represent 99.7% of the measurement.

We have the following in this problem:

Average of 78, the average 9 default.

 Calculating the percentage of students that passed the test.

\(Above 60\\\\60 = 78 - 2\times 9\)

Therefore 60 is under the average for two standard deviations.

Its normality test is symmetric, so 50% of such observations are below mean and 50% below mean.

Everything was cleared of the 50 percent above.

Of the 50% below, 95% (within 2 known mean deviations) succeeded.

therefore

\(p=0.5+0.5 \times 0.95=0.975\)

Answer:

448,648

Step-by-step explanation:

33,200/.074 = 448,648

Answer: 448648

Step-by-step explanation:

33,200 copies represent 7.4% of the total amount

-----------------------------------------------------

#1  33,200 ÷ 7.4%

- this is because how we get 33,200 by calculation is use the total amount and times 7.4% to get 33,200. So we are just working backwards. Since it was times before, then we divide after.

 33,200÷7.4%

=33,200÷0.074

≈448648 (you can't round up when the real amount is less the exact amount)

Solving a system of equations we can see that each pound of trail mix costs $3.50, and each pound of jelly beans costs $1.50

Let's define the variables:

Then we can write a system of equations so we will get:

5x + 3y = 22

2x + 12y = 25

To solve this, we can subtract 4 times the first equation fom the second one:

2x + 12y - 4(5x + 3y) = 25 - 4*22

2x + 12y - 20x - 12y = -63

-18x = -63

x = -63/-18

x = 3.5

That is the cost of each pound of trail mix, and replacing that in one of the equations:

2*3.5 + 12y = 25

y = (25 - 2*3.5)/12

y = 1.5

Hello!

I had this problem in a test, and there is an image of a right triangle in the test

We have been given an image of a right triangle and are asked to find the perimeter of our given triangle.

The answer is 10.3 units, Option A

Answer:

Linear

Step-by-step explanation:

The equation is in y intercept form.

The inverse of matrix A, if it exists, is:

A^(-1) = [7/43, 2/43; 10/43, 9/43]

To find the inverse of a matrix A, we need to determine if the matrix is invertible by calculating its determinant. If the determinant is non-zero, then the matrix has an inverse.

Given the matrix A = [9, -2; -10, 7], we can calculate its determinant as follows:

det(A) = (9 * 7) - (-2 * -10)

= 63 - 20

= 43

Since the determinant is non-zero (43 ≠ 0), we can proceed to find the inverse of matrix A.

The formula to calculate the inverse of a 2x2 matrix is:

A^(-1) = (1/det(A)) * [d, -b; -c, a]

Plugging in the values from matrix A and the determinant, we have:

A^(-1) = (1/43) * [7, 2; 10, 9]

Simplifying further, we get:

A^(-1) = [7/43, 2/43; 10/43, 9/43].

a. ΔR on [1,2] is mathematically expressed as:

ΔR = R(2) - R(1)

which means difference of population of rabbits after 2 months and after 1 month.

\(R(1) = 100(\frac{2}{5}.1 )\)

\(R(1) = 100(\frac{2}{5} )\)

R(2) = \(100(\frac{2}{5}.2 )\)

\(R(2) = 100(\frac{4}{5} )\)

\(\Delta R = 100(\frac{4}{5} )-100(\frac{2}{5} )\)

\(\Delta R = 100[\frac{4}{5} - \frac{2}{5} ]\)

\(\Delta R=\) 40

Difference of rabbits between first and second months is 40.

b. R(0) = 100(\(\frac{2}{5} .0\))

R(0) = 0

Initially, there no rabbits in the population.

c. R(10) = \(100(\frac{2}{5}.10 )\)

R(10) = 400

In 10 months, there will be 400 rabbits.

d. R(t) = 500

\(500=100(\frac{2}{5}.t )\)

\(\frac{500}{100}=\frac{2}{5}.t\)

\(t = \frac{500.5}{100.2}\)

t = 12.5

In 12 and half months, population of rabbits will be 500.
