40 members of parents organization are making candles to raise money. 1 member drops out and the rest make 3 more candlees each to make up. each member makes the same number of candles. how many candles do they make altogether?

4680 candles.

Step-by-step explanation:

Let the number that each of the 40 were to make be x candles. Then:

40x = 39(x + 3)

40x - 39x = 3*39

x = 39 *3 = 117.

So the total number of candles made = 40 * 117 = 4680 candles.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
