Answer:

Step-by-step explanation:

The binomial coefficient is calculated as:

$nCx=\frac{n!}{x!(n-x)!}$

It means that there are nCx ways to select x elements from a group of n elements.

So, If the researcher wants to determine the probability that 6 out of the next 8 individuals in his community are in favor of the president, we can replace n by 8 and x by 6 and calculated the binomial coefficient as:

$8C6=\frac{8!}{6!(8-6)!}=28$

Given the conversion factor which cube has the larger surface area?

Eduardwww [97]

Given the surface area of a cube as

$\begin{gathered} SA=6l^2 \\ \text{where l is the length} \end{gathered}$

Given Cubes A and B

$\begin{gathered} \text{Cube A} \\ l=19.5ft \end{gathered}$ $\begin{gathered} \text{Cube B } \\ l=6m\text{ } \\ \text{ in ft}\Rightarrow\text{ 1m =3.28ft} \\ l=6\times3.28ft=19.68ft \end{gathered}$

Find the surface area of the cubes and compare them to know which one is larger

$\begin{gathered} \text{Cube A} \\ SA=6\times19.5^2=6\times380.25=2281.5ft^2 \end{gathered}$ $\begin{gathered} \text{Cube B} \\ SA=6\times19.68^2=6\times387.3024=2323.8144ft^2 \end{gathered}$

Hence, from the surface area gotten above, Cube B has a larger surface area than Cube A

I don’t know how to solve things like this

EleoNora [17]

To do this problem you need to find angle adc which is a part of angle BDA. angle BDA is 90 degrees so the 2 parts must add up to 90 degrees so you set up the problem like this
-2x + 144 - 3x +51 =90
then you combine like terms
-5x +195 = 90
then you subtract 195 from 90
-5x = -105
then you divide -5 by -5 and -105 by -5 and get
x=21
then you plug x in and get your angle measure
-3(21) +51
then you get the angle measure as 114 degrees.

6/x = x-1<br> that 6overx = x-1

Juliette [100K]

6/x = x-1

Multiply x by both sides

6= x(x-1)

Set x and x-1 equal to 6

x = 6, x = 1+6 = 7
