The correct answer is 3.5

Two chords AC and BD are intersecting inside the circle. The Intersecting Chord Theorem states that when two chords intersect inside a circle, the products of their segments are equal.

Thus, for the given circle:
(AE) × (EC) = (BE) × (ED)

The lengths of the segments are
AE = 7
EC = 2
BE = 4
ED = ?

To solve for ED, we simply substitute the known values into the equation
ED =  \frac{7(2)}{4} = \frac{14}{4} = 3.5

What is the quotient?
Ray Of Light [21]

Answer:

4x-6+\frac{21}{x+5}

Step-by-step explanation:

First, we need to write the polynomial in descending order

Then, grab the term with the highest  power from the polynomial and divide it by the term with highest power from the polynomial located at the other side of the division symbol (this polynomial would be x+5)

The result (4x^2 / x) = 4x

This term will be part of the solution, and will be use to start the process of division.

This process start with the previous obtained term (4x), which will be multiplied by the polynomial from the other side of the division symbol (x+5).

The result another is another polynomial

This new polynomial will be multiply by negative 1

The new polynomial is then added to the poly (4X^2+14x-9)

The result will constitute a new poly, that will be use as the remaining of the division.

Since, our remaining differs from zero, and we still have member to simplify, we repeat the step 1 using the remaining as the new poly that needs to by divided by (x+5).

The attached picture explains the whole procedure.

Use the box plots comparing the number of males and number of females attending the latest superhero movie each day for a month
Harlamova29_29 [7]

(a) The IQR for the males' data is 12, because Q3 is at 15 and Q1 is at 3.

(b) The difference between the median values of each data set is 4 because 10-6 = 4

(c) For the males' data, the median would be a better measure of center, since the data is skewed right. For the females' data, the mean would be a better measure of center, because the data is pretty balanced (except for the outlier).

(d) Maybe a superhero movie had their opening night one day of this month, which would explain the outlier.

A construction crew is placing a square in a wall for a new window. The window is 3 1/8 feet wide. The wall has a length of 11 3
Sedbober [7]

Answer:

The window should be positioned 4 1/8 feet far from each edge of the wall.

Step-by-step explanation:

Since a construction crew is placing a square in a wall for a new window, which is 3 1/8 feet wide, while the wall has a length of 11 3/8 feet, and the crew wants to position the window at the center of the wall, to determine how far from each edge of the wall should the window be positioned, the following calculation must be performed:

1/8 = 0.125

3/8 = 0.375

(11,375 - 3,125) / 2 = X

8.25 / 2 = X

4.125 = X

Therefore, the window should be positioned 4 1/8 feet far from each edge of the wall.
