Answer:

The ratios are not equivalent

Step-by-step explanation:

First, in order to find the ratios, we have to change the month to the amount of days.

There are 30 days in April, so we will use this for the ratio.

The ratio for the 3 day weekend is 5:3

The ratio for the month of April is 60:30, which can be simplified to 2:1

So, the ratios are not equivalent, because 5:3 is not equal to 2:1

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:

$-560 x^4 y^3$
