Step-by-step explanation:

you can find the ratio by doing 12 / 6 and you will get 2 then you dump a 1 over the 2 to get 1/2 that's not how it works in all tho

What is the surface are of the container of oatmeal shown below? use 3.14 for pi

Serjik [45]

The surface area of a cylinder is:

$2 \pi rh+2 \pi r^2$

So fill in the equation and solve:

$2 \pi (8)(11)+2 \pi (8)^2$
$2 \pi 88+2 \pi 64$
$\pi 176+ \pi 128$
$\pi 304$
$3.14*304$
$954.56 cm^2$

Hope this helps!

What is the solution of (8x-8)^3/2=64<br>Edit; the answer is x=3

Talja [164]

I guess since you have the correct answer there that you need to know how to get it. Start by rewriting that exponent as a radical. It would look like this: $\sqrt{(8x-8)^3}=64$ . The first step is to undo that square root by squaring both sides. That will give you this: $(8x-8)^3=4096$ . Next we have to undo that cubing by taking the cubed root of both sides, leaving us with this: $8x-8=16$ . We add 8 to both sides to get 8x = 24 and x = 3.

The AAA system contains 3 independent components in parallel, each with probability of failure 0.4. Find the expected number of

Gre4nikov [31]

Answer:

Step-by-step explanation:

For each component, there are only two possible outcomes. Either it fails, or it does not. The components are independent. We want to know how many outcomes until r failures. The expected value is given by

$E = \frac{r}{p}$

In which r is the number of failures we want and p is the probability of a failure.

In this problem, we have that:

r = 1 because we want the first failed unit.

$p = 0.4[\tex]So[tex]E = \frac{r}{p} = \frac{1}{0.4} = 2.5$

The expected number of systems inspected until the first failed unit is 2.5

Thirteen people on a softball team show up for a game. a)How many ways are there to choose 10 players to take the field? b)How m

marishachu [46]

Answer:

a) 286

b) 1,037,836,800

c) 285

Step-by-step explanation:

a) Since order is not important, the total possible number of ways to choose 10 players out of 13 is the following combination:

$C(13,10)=\frac{13!}{(13-10)!10! } \\C(13,10)=\frac{13*12*11*10!}{(3*2*1)10! }\\C(13,10) = 286$

b) The total number of possibilities to assign positions by the selecting 10 players is the permutation of 13 players for 10 positions:

$P(13,10) = \frac{13!}{(13-10)!}\\P(13,10) = 13*12*11*10*9*8*7*6*5*4\\P(13,10) =1,037,836,800$

c) The number of ways to pick 10 players including at least one woman is equal to the total number of ways to pick 10 players (found in item a) minus the the number of ways to pick 10 players without picking a single woman.

Since there 10 male players for 10 positions, there is only one possible way to pick a team without women, therefore:

$P=286-1 =285$
