Angle E  and angle D  are equal

For CBE and CAD to be equal the remaining angle of the triangles would als have to be equal (because all angles of a triangle add to 180)

angle ACD is not equal to BCD    so   CAD cannot equal CBE

This might work for ya

(x+4)(x+8)     roots  -4   and -8       k = 32

Since the teacher is concerned with how difficult the words in a whole book would be, we can think of all the words in the book as the population. The sample would then be all the words she actually reads and assesses for difficulty, that is all the words contained in the first sentences of the first page of each chapter of the book. She is sampling using a method called systematic sampling. The three difficult words out of all the words she has read would indicate a level of difficulty that would have to be defined.

FV=PV(1+i)ⁿ   

FV=future value = 100 000

PV=present value= amount to invest now

i = interest rate in decimal form = .06

n = # compounding periods = 5 for this question

Plug in the numbers and solve for PV....

\((22.4, 26.5)\)is caalled a confidence interval. The way you form a confidence interval is by adding and subtracting the margin of error from the sample mean. so

\(26.5=sample\ mean+margin\ of\ error\), and

\(22.4=sample\ mean-margin\ of\ error\).

Solve the system of equations by adding the two equations to eliminate margin of error and get

\(2\times sample\ mean=22.4+26.5=48.9\), or

\(sample\ mean=\frac{48.9}{2}=24.45\).

So \(margin\ of\ error=26.5-24.45=2.05\)

The range is [-1,1].

a + b = 5 + (-3) = 2.

1. The number of values in the range of f(x) is 4.

2. H/G = -7/4.

3. a + b = 4 + (-2) = 2.

A + B + C = 2 + 3 + (-1) = 4.

i think posting answers is ok, just make sure they know why thats the answer because knowing the answer actually helps me a lot because most of the time it's just because i made a dumb mistake in my work. however if it's like a bajillion questions in a row about the same topic thats a little sus because it sounds like hw questions.. in that case i'd just give a few hints and give them a reminder to try it out first

ooh coool ok

As you can see from the underlined table (red for part (1) and blue for part (2)) , the numbers you want, 6 from each category for the first part, are:

Clothing and Jewlery: 011, 106, 135, 138, 109, 071

Food and Services: 157, 163, 154, 197, 174, 185

In the second part, your sample should have \(\frac{1}{4} \times 12 =3\) stores from Food and Services category since one fourth of the population is in that category; the rest, 9 stores, should be in the other category. These are underlined in blue:

Clothing and Jewlery:070, 143, 043, 036, 024, 117, 092, 126, 136

Food and Services:192, 193, 177

It is very easy to make mistakes reading the random digits table, so you should double check my answers. All you do is start at the line suggested and look at three digits at a time from left to right and select the ones that are in the range of IDs assigned to the stores. Read the table as if the digits followed one another in a continuous stream with no gaps for columns and no breaks for lines because in reality that is how it is and the digits are arranged in columns to give your eyes reference points.

Wait I realized my problem has a major flaw in it XD XD XD

The answer was so simple.

There are 8 integers n.

The number of ways is 204.

Just use the Web2.0 calculator to find:

sqrt(91) = 9.5393920141694565

Yes that sounds right.

oOoO aStRoNoMy

i'm pretty sure a nebula is a cloud of gas and dust in space

14) i'm going to assume that the slope is 6k. if that's the case, then

  6k = 2/3

18k = 2

    k = 1/9 :)

15) i'll assume again that your y-intercept is 4/3k. so

4/3k = -8

     4 = -24k

 -1/4 = k :)

also, i'm assuming you probably aren't the most familiar with what the terms mean in these equations..? so i'll try my best to explain it so i'm not just giving you answers :))

y = mx + b

y and x are the variables that are usually there. i hope that part doesn't need too much explanation

m is the slope, and b is the y-intercept. so in your two equations, in 14, 6k is the slope and -2 is the y-intercept. in 15, -1/2 is the slope and 4/3k is the y-intercept. usually m and b are common variables for defining the slope and y-intercept, respectively. ok i'm done word vomiting, hope this helped!

OH ok thank you!! so when i have something like that, i have to make it +- on the other side of the equation?
