What is the fourth term of the expansion of the binomial (2x + 5)^5?

Alik [6]

Ok, 1 bionimial theorem coming right up

for a binomial expansion of (a+b)^n
the kth term is
$\left(\begin{array}{ccc}n\\k-1\end{array}\right)a^{n-(r-1)}b^{k-1}$
$\left(\begin{array}{ccc}n\\k-1\end{array}\right)$ means $\frac{n!}{(k-1)!(n-(k-1))!}$

n is 5
4th term
4-1=3
and a=2x
b=5
so
$\left(\begin{array}{ccc}5\\4-1\end{array}\right)(2x)^{5-(4-1)}5^{4-1}$
$\left(\begin{array}{ccc}5\\3\end{array}\right)(2x)^{2}5^{3}$
$\left(\begin{array}{ccc}5\\3\end{array}\right)(2x)^{2}5^{3}$
(10)(4x^2)(125)
5000x^2 is the 4th term

Which statement is always true about the measures of corresponding angles?

kiruha [24]

The answer is B.

complementary means adding upto 90 degrees, but they dont unless they're both 45 degrees, so its not A.

they are not supplementary because that means they add up to 180 degrees and they dont unless theyre both 90 degrees, so its not C.

there IS a relationship between the measures of corresponding angles, so its not D.

the relationship between them is that they are always the same, so the answer is B.

A box contains 1414 large marbles and 1111 small marbles. Each marble is either green or white. 66 of the large marbles are gree

Luba_88 [7]

Answer:

0.9739

Step-by-step explanation:

We have 1111+1414=2525 marbles, and

44 small white matbles and

1414-66=1348 big white marbles.

So we have 44+1348=1392 white marbles.

The probability to choose small marbles is P(s)=1111/2525=0,44

The probability to choose white marbles is:

P(w)=1348/2525=0,5513.

The probability to choose small and white is:

P(s and w)=44/2525=0,0174

The probability to choose small or white is:

P(s or w)= P(s)+P(w)-P(s and w)=0,44+0,5513-0.0174=0,9739
