Answer:
0.0862 = 8.62% probability that Heather reaches in the bag and randomly selects 2 peanut butter cookies from the bag
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcoes.
The order in which the cookies are selected is not important, so we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
2 peanut butter cookies, from a set of 4. So
Total outcomes:
2 cookies from a set of 5+8+9+4 = 26. So
Probability:
0.0862 = 8.62% probability that Heather reaches in the bag and randomly selects 2 peanut butter cookies from the bag
Answer:
20 waves
Step-by-step explanation:
Out of 50 waves, Mark will catch 20 waves. To find this, first, you have to put it into a ratio.
8 x
--- = -----
20 50
To solve this, you need to multiply 8 x 50, which is 400. Next you need to divide 400 by 20, which is 20 waves.
This means x = 20 waves.
Hope this helped!! :) If you have any questions, make sure to comment!!
[12(.3)+x(1)]/(12+x)=.4
3.6+x=4.8+.4x
.6x=1.2
x=2 qts
(though your radiator would still be short a quart for doing so :) )
Answer:
96.74
Step-by-step explanation:
If you were to do this math it would be: 258 divided by 6 equals 43, you can multiply 6 times 40 equals 240 subtract 240 minus 258 which equals 18. then you can divide 18 by 6 which gets you 3 then 40 plus 3 equals 43
