Answer:
2.4 bags
Step-by-step explanation:
Uh you can keep your brains.
Using the data table, we get:
1, 2, 2, 3, 4 as our data.
Finding the mean:
(1+2+2+3+4)÷5=
12÷5=
2.4 bags

you add both years worth of biking together!
Answer:
Step-by-step explanation:
15 is the answer . What you do is unsimplify 2/5 which equals .4 . Then divide 6 and .4 which is 15
So,
The probability of drawing a yellow marble is
![\frac{3}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B7%7D%20)
.
Since he replaces the marble after it is drawn out, the probability of drawing another yellow is the same:
![\frac{3}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B7%7D%20)
.
The probability of drawing a red marble is
![\frac{4}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B7%7D)
.
In order to get the probability of drawing 2 yellow marbles and 1 red marble, given that each marble is replaced after it is drawn out, we must multiply the fractions together.
![( \frac{3}{7} )( \frac{3}{7} )( \frac{4}{7} ) = \frac{36}{343}](https://tex.z-dn.net/?f=%28%20%5Cfrac%7B3%7D%7B7%7D%20%29%28%20%5Cfrac%7B3%7D%7B7%7D%20%29%28%20%5Cfrac%7B4%7D%7B7%7D%20%29%20%3D%20%20%5Cfrac%7B36%7D%7B343%7D%20)
Because the order of the marbles doesn't matter, we will multiply the probability by 3.
