Hey there, 

Lets solve this equation step by step. 

⇒ First of all, <span>Simplify </span><span>2x×3y</span><span> to </span><span>6xy 
</span>
6xy-3x^2+7y * 2x-12y 

⇒ Now <span>Simplify </span><span>7y×2x</span><span> to </span><span>14yx
</span>
6xy-3x^2+14yx-12y 

⇒ <span>Gather like terms 
</span>
(6xy+14xy)-3x2-12y&#10; &#10; 

⇒ <span>Simplify everything 
</span>
20xy-3x^2-12y 

                                        Hence Simplified.

Okay, so if you have 2x*3y-3y*2+7y*2x-12y, add all your like terms together. If you have a constent, add it to the equation.

4x-2y*2 (<- I think this is my correct answer, haven't done this in a while.)

According to a 2010 study conducted by the Toronto-based social media analytics firm Sysomos, 71% of all tweets get no reaction.
klemol [59]

Answer:

a) the expected number of tweets with no reaction is 71 tweets

b) the variance is 20.59 tweets² ( ≈ 21 tweets )and the standard deviation is

4.537 tweets (≈ 5 tweets)

Step-by-step explanation:

we can use the binomial probability distribution

P(x, N, p ) = N!/[(N-x)!x!] * p^x * (1-p)^(N-x)

where

x = number of successful events

N = population total

p = probability for success for every individual and independent event

P = probability for x successful events

in our case p = 71% = 71/100 (probability of a tweet without reaction) , N = 100 tweets

a) the expected number of tweets

E(x) = N* p = 100 tweets * 71/100 = 71 tweets

b) the variance is

V(x) = N * p * (1-p)

V = 100 * 71/100 * (1-71/100) = 71* 29/100 = 20.59 tweets² ( units of variance are [N²] )

the standard deviation is

s = √V = √20.59 tweets² = 4.537 tweets

Find the inverse function of f(x)=4x-8
kipiarov [429]

Answer:

f^-1(x)=1/4x+2

Step-by-step explanation:

y=4x-8

change x and y

x=4y=8

switch sides

4y-8=x

add 8

4y=x+8

divide both sides by 4

y=1/4x+2

substitute f^-1(x) for y

f^-1(x)=1/4x+2
