What is the fourth term in the binomial expansion of (2x – y) 7?
nata0808 [166]

Answer:

(7C4) (2x)^4 (-y)^{7-4}

And replacing we got:

35 (2^4) x^4 (-y)^{-3}

And then the final term would be:

-560 x^4 y^3

Step-by-step explanation:

For this case we have the following expression:

(2x-y)^7

And we can use the binomial theorem given by:

(x+y)^n =\sum_{k=0}^n (nCk) x^k y^{n-k}

And for this case we want to find the fourth term and using the formula we have:

(7C4) (2x)^4 (-y)^{7-4}

And replacing we got:

35 (2^4) x^4 (-y)^{-3}

And then the final term would be:

-560 x^4 y^3

First we will go to the section that lists that students that like hotdogs.  76 students out of 150 like hotdogs.  Out of those 76 students, which of them like burgers?  
32 students like hotdogs and burgers.  32/76 is equal to .421..., which when multiplied by 100 is equal to approximately 42.1%.  We found the conditional frequency, or the column frequency.  The correct answer is C.
