You need to find the area of the trapezoid whose "height" goes from 2.5 to 3.5 and whose midline has a length of 0.10. 

Area  =  base · midline  =  1 · 0.10  =  0.10

Unfortunately, I don't find that answer.

I would help you here but I do not know how to do it.

****What is p(3 <  x < 6) ?

Add the heights (the probabilities) of the three rectangles that represent 6 or more trees.

You did not write it on one question. You wrote a general comment.

You did thank your answerers, which was nice, but even so, the comment sounded arrogant.

The comment should have been on the thread that you were talking about.

It was not appropriate to place it as a new 'question'.

There was a reply left saying you should have shown 'us' how to do it.

This reply was whited out because the person was using 'language' to display his/her annoyance.

But he was right.

If you ask a question here, then find out how to do it elsewhere, you should share your new knowledge here.

Take  X  times  P  for each ordered pair and add the results.

Answer  =  (0)(0.15)  +  (4)(0.25)  +  (8)(0.50)  +  (12)(0.05)  +  (16)(0.05)

In a binomial distribution, you need to have the same probability of success for each draw and you need to know how many draws.

The first situation has both of these qualifications.

The second doesn't because the probability of success changes from draw to draw.

The third and fourth don't because you don't know how many draws.

There are 8 possible outcomes.

1 of those 8 gives a result of 0.  1/8  =  0.125

2 of those 8 give a result of 1.    2/8  =  0.250

1 of those 8 gives a result of 2.  1/8   =  0.125

4 of those 8 give a result of 3.    4/8  =  0.500

Find the answer which has those probabilities.

We don't really have an account for that website.

15/4 = 3.75 OR 3 3/4. So she used 3 3/14 cups of orange juice per pitcher.

Divide: 15 /  15/4.

Reciprocal of second number:  15 *  4/15 = 60/15 = 4 pitchers.

Creatures = I think it's a noun. Person, place or thing.

And = Conjunction

"Clean" = Adjective?

Downpour = Noun?

Themselves = I think it's Pronoun??

Sense = Verb?

"a" = Preposition...?

Seperates their: Ummm I know "their" is a pronoun, and "seperates" is a verb. Soooo. Verb?

"Indicate" = IDK Verb?

Themselves just: Themselves = pronoun. Just = Adverb. Sooo... Adverb? 

The rest, I'm not sure...

CPhill: I think it says "ONE card" was removed and the total of the remaining cards is a multiple of 32.

So, [80 x 81] / 2 =floor[3240 / 32] =101 x 32 =3232. 

So, one card with No.8 on it was removed.

Call the  height of the  neighboring building, H

And call the  distance  between the buildings  = D

So we have that

tan(34°)  = [ 56 - H ] / D

D =  [56 - H ]/ tan (34°)

And we also  have that

tan (63.7)  =  56/ D   

tan (63.7)  = 56 /[ (56 -H) / tan(34) ]

tan (63.7)  = 56 tan (34) / [ 56 - H ]

[ 56 - H ] tan (63.7)  = 56 tan (34)

56 tan (63.7)   - H tan (63.7)  = 56 tan (34)

H tan (63.7) = 56 ( tan (63.7) - tan (34) ]

H =  56 [ tan (63.7) - tan (34) ] /  tan (63.7)  ≈   37.3  ft

For the first problem, we know that all the angles in a triangle add up to 180˚. That means: x + ( 2x + 5 ) + ( 3x + 7 ) = 180.

Since addition is associative, x + ( 2x + 5 ) + ( 3x + 7 ) = 180 is the same as x + 2x + 5 + 3x + 7 = 180.

Combining like terms, we get: 6x + 12 = 180.

After we move 12 to the other side so the x is iscolated, we get: 6x = 168.

Dividing each side by 6 gets us to: x = 28, so the answer to the first problem is D.

I hope this helped! I might've made a mistake, so if you catch one, please lmk! <3

We have this system

E  + C  +  P    =  300     (1)

3C + 4P = 90     →  4P = 90 - 3C  →  [90 -3C ] / 4  = P    (2)

2E + C  = 564    →   2E = 564  - C  →  [ 564 - C ] / 2   = E    (3)

Sub (2) and (3)   into (1)    and we have

[564 - C ] / 2   +   C  +  [90 - 3C ] /4   =  300    multiply through  by 4

1128 - 2C  + 4C  + 90 - 3C  = 1200   simplify

1218  - C  =  1200

C = 1218 - 1200  =   18mg  in the cupcake

[90 -3 (18) ] / 4 = 36/4 =   9 mg  in the pizza

[564 - 18] /2  =   273 mg  in  the egg

a) I probably don't understand the question... does the order of the color matter? If not: there are 4! = 24 ways to arrange the blocks in a row??

Here's my best attempt  :

sum  of integers  1 - 80 =   (80) (81) / 2 =  40 * 81  = 3240

Nearest integer  < 3240  which is divisible by  32 =  3232

So.... the cards that could have  been removed are multiples of 8 + a multiple  of 32  = 

8 , 40 , 72

So....the sum on these cards  =  48 + 72 =   120

So you have a 1/6 chance of getting a 5 on the first dice.

The second dice you ALSO have a 1/6 chance of getting a 5.

1/6 * 1/6 = 1/36.

Probability = 1/36.

Note that water  contains   0%  ethyl alcohol

And 70% non-alcoholic   =  30%  alcohol

So....we have this equation wher x   is the quantity (in ounces)  of water to be added

.45 (8)  +  0 (x)  =  .30 (8 + x)      simplify

.36   =   .24 + .30x      subtract  .24  from both sides

12  = .30x                 divide  both  sides  by  .30

x =  40  ounces of water

No numbers..

Well, complementary angles are two angles who add up to 90 degrees.

Supplementary angles are two angles who add up to 180 degrees.

So it's false.

Bob can drive 50 miles in 40 minutes. Sam can drive 90 miles in 105 minutes. If d is the time (in hours) it takes for Bob to drive 120 miles and e (in hours) is the time it takes for Sam to drive 120 miles, what is the |d-e|? Express your answer as a decimal to the nearest hundredth.

Bob  drives    50 mi /40 min  = (5/4)mi /min

So the time it takes him to  drive  120 mi    =     120  / [5/4] = 120 * 4  / 5=   96 min =  96/60 =  8/5 hrs

Sam drives    90 /105 =  6/7  mi/ min

So....the time it takes him to  drive   120 miles =  120 / [6/7 ]  =   120 * 7 / 6 =  140 min  =  7/3 hrs  

So  l  d  - e  l    =   l 8/5 - 7/3  l   =  l (24 - 35) / 15  l  =   l  -11 / 15  l  =   11/ 15  ≈  0.73
