Answer:

To Find the median you order them from least to greates or vice versa, therefore 4,5,6,6,12,17,19  the median would be 6 because it is in the middle, the mean would be adding all of them and dividing by 7 because there are 7 variables. therefore the mean is 9.85 or you can round to 10 / 9.9

Answer:

20:21

Step-by-step explanation:

Let's first start by converting each ratio so that the number of girls is the same

2:3

4:7

The least common multiple of 3 and 4 is 12 so...

8:12

  12:21

We add 8 and 12 to get the number of junior members...

8+12=20

Then we put it in a ratio with the amount of adult members...

20:21

Monica deposits ​$300 into a savings account that pays a simple interest rate of 3.9​%. Paul deposits ​$400 into a savings accou
tiny-mole [99]

Answer:

monica because with 3.4 % that is more than 2.3% and that is what they want to know so its monica

Step-by-step explanation:

The formula for calculating simple interest is given by :

S.I = \frac{ptr}{100}

For Monica

S.I = 300 x 3.4 x 1 / 100

S.I = $10.2

For Paul

S.1 = 400 x 2.4 x 1 / 100

S.I = $9.6

Therefore : Monica earned more interest

Monica's intrest rate is 1,224 and paul's is 840 so it would be monica.

(Hope this helps can I pls have brainlist (crown)☺️)
