The interquartile range is 6.

all you have to do is find the range of where that rectangle starts and ends, so 9-3=6. hope that helps :)

6.

The upper quartile is at 9. The lower quartile is at 3. The inner quartile range is the difference of those 2 numbers. 9-3=6

A seller of the property listed at $200,000 excepted a 90% offer the home appraised at $185,000 and the buyers obtained a loan f

Elza [17]

Answer:

$637.50

Step-by-step explanation:

According to the Question,

Given That, A seller of the property listed at $200,000 excepted a 90% offer the home appraised at $185,000 and the buyers obtained a loan for 85% for 30 years at 5% interest

Thus, the first months interest is

$200,000 list price x 0.90 = $180,000 contract sales price.

Since lender always uses the less of the appraised value or the contract sales price, use $180,00 for the remainder of the calculations.

$180,000 contract sales price x 0.85 LTV = $153,000 loan.

$153,000 loan x 0.05 interest rate = $7,650 annual interest.

$7,650 ÷ 12 = $637.50 monthly interest payment for the first month.

The figures below are rectangles. Which polynomial represents the area of the shaded region? HAVE ALL MY POINTS but answer truth

Aleks04 [339]

Answer:

$7x - 1$

Step-by-step explanation:

Area of the shaded region = area of the large rectangular - area of the small rectangle

Area of rectangle is given as l*w

Area of the large rectangle = $l*w = (x + 5)(x - 1)$

Expand

$= x(x - 1) +5(x - 1)$

$= x^2 - x + 5x - 5$

Area of large rectangle $= x^2 + 4x - 5$

Area of small rectangle = $l*w = (x + 1)(x - 4)$

$= x(x - 4) +1(x - 4)$

$= x^2 - 4x + x - 4$

Area of small rectangle = $= x^2 - 3x - 4$

Area of shaded region = $(x^2 + 4x - 5) - (x^2 - 3x - 4)$

$= x^2 + 4x - 5 - x^2 + 3x + 4$

Collect like terms

$= x^2 - x^2 + 4x + 3x - 5 + 4$

$= 7x - 1$

What is the equation in slope intercept form of the perpendicular bisector of the given line segment?

andreev551 [17]

Answer:

y = -4x - 6

Step-by-step explanation:

The equation of a line in point-slope form.

$y - y_1 = m(x - x_1)$

is the equation of the line containing point (x1, y1) and having slope, m.

The given point of the perpendicular bisector is (-1, -2), so in this case, x1 = -1, and y1 = -2.

We need the slope of the perpendicular bisector. First we find the slope of the segment. We start at point (-5, -3). We go up 1 unit and 4 units to the right, and we are at another point on the segment. Since slope = rise/run, the slope of the segment is 1/4. The slopes of perpendicular lines are negative reciprocals, so the slope of the perpendicular bisector is the negative reciprocal of 1/4, so for the perpendicular bisector, m = -4.

Now we use the equation above and our values.

$y - y_1 = m(x - x_1)$

$y - (-2) = -4(x - (-1))$

$y + 2 = -4(x + 1)$

$y + 2 = -4x - 4$

$y = -4x - 6$
