Thank you for the help, sorry I just got online.

Hey bestie it's me 

I got 84 because I found that x=8, y=7, and z=6.

ONE standard deviation below 74   is     74 - 1.5 = 72.5      z -score = .1587

   77 is two standard deviations ABOVE 74      z-score = .9772

we want to now the area between these z-scores

   .9772  -  .1587 = .8185              so  81.85%  out of 100% of the scores are between  72.5  and 77

okay thank you

You most likely have to calculate the total probability (the denominator). Idk if this next step is right. You have to add the 2nd shot probability to the 4th shot probability. 1/4+1/2=3/8? Then find the numerator by multiplying the denominator by 3/8? 

Btw, you are not multiplying the 2nd and the 4th because we are not trying to find if both have the dumpling shot out. So add. 

i see where you are going but how do i calculate it getting shot out from the 2nd or 4th time?

Thx CPhill

m∠L  +  m∠P   =   180°

(14x - 22)°  +  (4x + 4)°   =   180°

14x - 22  +  4x + 4   =   180

18x + 18   =   180

18x   =   180 - 18

18x   =   162

x   =   162/18

x   =   9

Now that we know  x  we can find the measure of angle  P

m∠P   =   (4x + 4)°   =   (4(9) + 4)°   =   (36 + 4)°   =   40°

I probably won't help but it might.

The probability of the dumpling being shot out on the first try is 1/5. The probability of it being shot out on the second try is 1/4 because there are only 4 places where the dumpling can be shot out of. The third is 1/3. The fourth is 1/2. The fifth is 1 because it is the only place where the dumpling can be shot out of.

Note that we can find  the hyppotenuse^2 of  the  triangle on the  right  as

8^2  + 4^2  = h^2

64 + 16 = h^2 =  80

So...on the left....x is the  hypotenusr of   that  triangle  so

h^2  + 7^2   =x^2

80  +  49   = x^2

129  = x^2

sqrt (129)   = x

y   =   3x + 10

3x + 2y   =   16

                                       Since  y = 3x + 10  we can replace  y  with  3x + 10

3x + 2(3x + 10)  =  16

                                       Distribute  2  to the terms in parenthesees

3x  +  6x + 20   =   16

                                       Combine  3x  and  6x  to get  9x

9x  +  20   =   16

                              Subtract  20  from both sides of the equation

9x   =   -4

                              Divide both sides of the equation by  9

x   =   -4/9

Now that we know  x  we can plug this back into the first equation to find  y

y   =   3x + 10   =   3(-4/9) + 10   =   -4/3 + 10   =   26/3

So the solution to the system of equations is  (-4/9, 26/3)

Note   k *  log _y x  can be written as   log _y x^k

Using  the  change-of-base  we  have  that

log x^3  /  log y^5    =   log x^k    / log y       and we can write

3 * log x  / 5* log y  =  k * log x  / log y        multiply both sides  by  log y  /log x    and we get that

3  /  5   =   k

Let  the  equal number of tickets =  n

So

5n + 8n ≤ 75

13n ≤ 75

n ≤  75  /13 

n ≤  5.76

She can buy   5 tickets of each type =  10 tickets total

Proof

5(5)  + 8(5)  =   $65

If she   bought 6 tickets each....she would spend

5(6)  + 8(6)  =  $78     (too much)

The most he can spend on the album is $12.93

Is this a multiple choice question? If so, what are the choices?

y=3x+10

3x+2y=16

y-3x=10

2y+3x=16

2y-6x=20

2y+3x=16

-9x=4

x=-4/9

(-4/9,26/3)

its okay 

hmmm

I don't think I understand. :((

I'm really sorry. 

=^._.^=

s<= 4

hope this helps

nope everything listed above is word to word from the question

Did the question include the probability of the dumpling coming out?

Or perhaps I'm missing something.

You're welcome. :)))

thank you <3

Hello Jenny :))

So we need to calculate the probability it shows heads 5 and 2 tails. 

That's just 7!/5!/2! = 21. 

So there are 21 ways of ordering it. 

Now the probability that one of these sequence happens is (2/3)^5*(1/3)^2. 

So our answer is (21)*(2/3)^5*(1/3)^2

I hope this helped. :)))

idk this is hard
