(2/5)+(3/(5x))=(x+5)/10
nasty fractions, we hates it forever

so

get rid of all those nasty fractions
multiply both sides by 10x
4x+6=x(x+5)
distribute
4x+6=x^2+5x
minus (4x+6) from both sides
0=x^2+x-6
factor
0=(x-2)(x+3)
set each to zero
0=x-2
2=x

0=x+3
-3=x

x=-3 and 2

Pamela is a leading server on her volleyball team. On average she serves at 8:44% of the time. She attempts 25 serves in her nex
Dima020 [189]

Answer:

She should be expected to have 2.11 aces.

Step-by-step explanation:

I suppose there was a small typing mistake. It should be: On average she gets an ace of 8.44% of her serves.

Then

For each serve, there are only two possible outcomes. Either there is an ace, or there is not. The probability of there being an ace in a serve is independent of other serves. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

E(X) = np

She gets an ace of 8.44% of her serves.

This means that p = 0.0844

She attemps 25 serves:

This means that n = 25

How many aces would you expect her to have

E(X) = np = 25*0.0844 = 2.11

She should be expected to have 2.11 aces.

ser-zykov [4K]

hi <3

84 + 4m = 276

Linda purchased a prepaid phone card for $30. Long distance calls cost 17 cents a minute using this card. Linda used her card on
Vedmedyk [2.9K]

Answer:

23 minutes

Step-by-step explanation:

First, take away $26.09 from $30. This will show you how much was spent on the call. You should get $3.91.

Next, it may be easier to convert this total all to cents. So 100 cents in every dollar...100 cents times 3 = 300 cents. Then add the other 91 cents to get a total of 391 cents.

Then, you need to divide 391 cents by 17 to get the minutes. And you'll get 23 minutes!
