To know whether people can bargain the price down when purchasing a house at a 5% level of significance, we need to put a hypothesis test. The null hypothesis would be that people cannot bargain the price down

To determine whether 3-bedroom houses are cheaper than 4-bedroom houses, we would again give out a hypothesis test. The null hypothesis would be that there is no difference in price between 3-bedroom and 4-bedroom houses.

but the other hypothesis would be that 3-bedroom houses are cheaper than 4-bedroom houses.  If the p-value is less than 0.05, we can reject the null hypothesis and say that 3-bedroom houses are more cheaper than 4-bedroom houses.

Which number line model represents the expression 2.5 + 4.5?

The expression that represents the perimeter of the rectangle in centimeters is 45.2g - 30.6h.

Let's start by finding the length of the top and bottom sides, which are equal to the width. The width is given by (9.8g - 4.5h) centimeters, so the length of the top and bottom sides is:

2(width) = 2(9.8g - 4.5h) = 19.6g - 9h

Next, we need to find the length of the left and right sides, which are equal to the length. The length is given by (1.5g - 3.4h) centimeters, so the length of the left and right sides is:

2(length) = 2(1.5g - 3.4h) = 3g - 6.8h

Now that we have the lengths of all four sides, we can find the perimeter of the rectangle by adding them together:

Perimeter = length + width + length + width

Perimeter = (3g - 6.8h) + (19.6g - 9h) + (3g - 6.8h) + (19.6g - 9h)

Perimeter = 45.2g - 30.6h

The acceleration of the system is 0.83 m/s² and the tension in the string is 8.3 N.

The acceleration of the system can be calculated using Newton's second law of motion. The equation is F = ma, where F is the net force on the system, m is the total mass, and a is the acceleration. Since the two masses are connected by a light inextensible string, the net force acting on the system is equal to the tension in the string. Therefore, the equation becomes T = (5 kg + 2 kg)a, where T is the tension and a is the acceleration. Solving for a, the acceleration is found to be 0.83 m/s². The tension in the string can also be calculated using the equation above. Plugging in the acceleration, the tension is found to be 8.3 N.

As a decimal, the number is:

The trigonometric ratios can find the missing side of a right triangle given an angle, such as by using the tangent ratio to calculate the adjacent side length when given the length of the opposite side.

The trigonometric ratios are used to calculate specific values of a triangle. The three main ratios are sine, cosine, and tangent. The sine ratio is the ratio of the side length opposite the angle to the hypotenuse of the triangle. The cosine ratio is the ratio of the side length adjacent to the angle to the hypotenuse of the triangle. The tangent ratio is the ratio of the side length opposite the angle to the side length adjacent to the angle.

To find the missing side of a right triangle, given an angle, we use the trigonometric ratios. For example, if we have an angle of 45 degrees and a side length of 8, we can use the tangent ratio to calculate the missing side length. To do this we use the formula tan(45) = opposite/adjacent. We know the opposite side is 8, so to calculate the adjacent side we solve for x in the equation 8/x = tan(45). We get x = 8/tan(45), and x = 8/1 = 8. Therefore, the adjacent side length is 8.

The equation of a line perpendicular to line QR in slope-intercept form that contains point (5, 6) is y = 2x-4.

y = mx + b is the slope intercept form of writing the equation of a straight line. In the equation 'y = mx + b', 'b' is the point, where the line intersects the 'y axis' and 'm' denotes the slope of the line.

Given that a line QR has an equation is x+2y = 2, we need to find the equation of a line passing through (5, 6) and is perpendicular to the given line,

Converting the equation into slop-intercepts form,

y = -0.5x+1

Here, slope m = -0.5

We know that the slopes of the perpendicular lines are negative reciprocal of each other,

Therefore, the slope of the asked line is 2.

So, its equation =

y = 2x+c

To find c, put x = 5 and y = 6

6 = 2(5) + c

c = -4

Therefore, the final equation will be =

To have a higher salary than 99% of her male counterparts, a woman would have to make more than $5229.48 per month, or $62753.76 per year

To find out how much a woman would have to make in a year to have a higher salary than 99% of her male counterparts, we need to find the salary level that corresponds to the 99th percentile of the male salary distribution.

First, we need to calculate the standard deviation of the annual salaries for both men and women. Since the standard deviation of the monthly salaries is $300, the standard deviation of the annual salaries can be calculated as:

σ_annual = σ_monthly * √12 = 300 * √12 = $1039.23

Next, we can calculate the salary level that corresponds to the 99th percentile of the male salary distribution using the standard normal distribution table.

z-score for the 99th percentile = 2.33

salary level for the 99th percentile of male salary distribution = mean + z-score * σ_annual

= $2750 + 2.33 * $1039.23 = $5229.48 (rounded to the nearest cent)

There will be 8980 illiterate people in Sylvania 4 years from now if the country continues to reduce the number of illiterate citizens by 5 each year.

We can write a function P(t) to represent the number of illiterate people in Sylvania t years from today, where t is the number of years after the current year.

Given that the country has decided to reduce the number of illiterate citizens by 5 each year, we can subtract 5 from the number of illiterate people each year.

The initial number of illiterate people in the country is 9000. So, the function can be written as:

P(t) = 9000 - 5t

where t is the number of years after the current year.

For example, if we want to find out how many illiterate people will be in Sylvania in 4 years from now, we can substitute t with 4:
