The ratio of laptop to desktop computers at a middle school. Is 8 to 6. If there are 462 desktop computers, how many computers i

Aleksandr-060686 [28]

Answer:

1078

Explanation:

For this you can use a proportion to solve. So first we set up the proportion as laptop over desktop is equal to "l" over total desktop computers. Let l be the total amount of laptops which is what we must first solve for.

$\frac{8}{6}=\frac{l}{462} \\$

Then we cross multiply.

$6l=3696\\$

Now we can solve it as a regular algebra problem,

$\frac{6}{6}l = \frac{3696}{6}\\ l=616$

Now that we know how many laptop computers there are we can find the total number of computers in the school. We simply add the total number of desktop computers to the total number of laptop computers.

$462+616=1078$

And that is the answer. 1078.

First you do the parenthesis

then you do the exponent in the parenthesis

Then the multiplication in the parenthesis

then when you are done multiplying in the parenthesis

then u multiply the answer in the parenthesis with 1/3

and then you are done

According to a survey done at your school, about 42% of all the female students participate in 2 sport seasons. You randomly ask

IRISSAK [1]

Answer: 0.353

Step-by-step explanation:

We know that 42% of all the female students participate in 2 sports this season. (58% is the percent that did not)

This means that if we select a random student, there is a 0.42 probability that the student did participate in 2 sports this season.

Other thing that i will use is that, if we have a group of N objects, and we want to create a group of K objects out of the N, the number of combinations is:

$c = \frac{N!}{(N - K)!*K!}$

Now, out of 5, we want to find the proability that, at least 3 of them, did participate in at least 2 sports this season.

The probability that all 5 of them participated, is equal to the product of the individual probabilities. (so N = 5, and K = 5)

P = (0.42^5)*1 = 0.013

Now, if only 4 of them did participate (N = 5, k = 4), the probability is equal to:

P = (0.42^4)*(0.58)*5!/4! = (0.42^4)*(0.58)*5 = 0.09

The probability for only 3 is: (N = 5 and K = 3)

P = (0.42^3)*(0.58^2)*5!/(3!*2!) = (0.42^3)*(0.58^2)*(5*4/2) = 0.25

Then the total probability is:

P = 0.013 + 0.09 + 0.25 = 0.353
