To solve this problem, we must use the chord-chord power theorem, which states that the arcs that are determined by the segments of the chords, when added and divided by two, equal the inside angles.

First, let's find angle AED.

AD = 86 and BC = 96. 86+96 = 182 and (1/2)(182) = 91

Therefore, Angle AED = 91 degrees.

Next, let's find angle AEC.

We know that angle AEC is supplementary to angle AED because the sum of these two angles determines a straight angle, which measures 180 degrees,

Therefore, Angle AEC = 180 - 91 = 89 degrees.

(Note: If you were to use the chord-chord power theorem for Angle AEC, you would get the same answer)

The answer to your question is D. m<AED = 91, and m<AEC = 89

The distribution of individual incomes in the United States is strongly skewed to the right. In 2013, the mean and median income

vesna_86 [32]

Answer:

The mean would be $322,343 and the median would be $196,723.

Step-by-step explanation:

Since the distribution of individual incomes is skewed to the right, it means that the distribution has a long right tail.

Drawing a distribution with this characteristic, we can see how the majority of the data falls into the left side of the graphic, meaning that a lot of people receive less income. Following this reasoning, the mean which is the amount of the data (in this case individual income) divided by the amount of people, would be the higher number, meaning that the few people who earn more money would influence in making this number higher.

Following this reasoning, the median (which is not influenced by this difference) would be the less high number.

So far this year, the average monthly revenue at Lexington Times is 50,711. That is 5% less than the monthly average was last ye

SOVA2 [1]

53,380 was the average last year .

<u>Step-by-step explanation:</u>

Here we have , So far this year, the average monthly revenue at Lexington Times is 50,711. That is 5% less than the monthly average was last year. We need to find that What was the average last year . Let's find out:

Let the monthly average was last year be x , According to question the average monthly revenue at Lexington Times is 50,711 but , That is 5% less than the monthly average was last year . Following equation for above scenario is :

⇒ $x-\frac{5(x)}{100}=50711$

⇒ $\frac{100x-5x}{100}=50711$

⇒ $\frac{95x}{100}=50711$

⇒ $\frac{95x(100)}{100(95)}=\frac{50711(100)}{95}$

⇒ $x=\frac{50711(100)}{95}$

⇒ $x=53380$

Therefore , 53,380 was the average last year .

Answer: 2.)non function 3.)non function 4.) function 5.)non function 6.) non function 7.)function 8.)non function PART B 1.)non function 2.)function 3.) function

Step-by-step explanation: a function is when the domain (x) all each have one answer like (-2.6)(7,4)(8,6) there can be repeating ranges (y) just not domains.

A non function is when one domain (x) has multiple ranges(y) like (7,2)(-9,6)(7,9) the 7 repeats twice giving it two ranges, which causes it to be non functional. hope that helped :))

OMG JUST REALIZED I FORGOT TO PUT PICTURES THE FIRST 2 TIMES SO SORRY PLEASE HELP!

I got it now!

(hold your applause)

Area of the rectangle is 12 to the power of 2 (or you can just say squared) and that equals 144cm squared

the area of the circle is pi radius squared (in this case radius is 3) and it equals 9 pi squared

to get the shaded area that is last over with the circles removed you would have to do (144)-(9pi) (this part is unachievable without a calculator that has the pi symbol to fill in instead of just writing 3.14) and after you get the answer of that which is 115.725666118

and that amount you must do the same with so it would be

(115.725666118)-(9pi) and that equals ...............

87.4513322357

Nat2105 [25]

I will show you how to do #5:

a). -20 + 2(n-1) Original Expression
-20 +2n - 2 Distributive Property
-22 + n Combine Like Terms

Final Expression: -22 + n

b). 1.5 + (-2.5)(n -1) Original Expression
1.5 + -2.5n + 2.5 Distributive Property
4 - 2.5n Combine Like Terms

Final Expression: 4 - 2.5n
