The solve for n would be 11
2 to the second power is 4 and 4x11=44
Answer:
0.3431
Step-by-step explanation:
Here, it can work well to consider the seeds from the group of 18 that are NOT selected to be part of the group of 15 that are planted.
There are 18C3 = 816 ways to choose 3 seeds from 18 NOT to plant.
We are interested in the number of ways exactly one of the 10 parsley seeds can be chosen NOT to plant. For each of the 10C1 = 10 ways we can ignore exactly 1 parsley seed, there are also 8C2 = 28 ways to ignore two non-parsley seeds from the 8 that are non-parsley seeds.
That is, there are 10×28 = 280 ways to choose to ignore 1 parsley seed and 2 non-parsley seeds.
So, the probability of interest is 280/816 ≈ 0.3431.
___
The notation nCk is used to represent the expression n!/(k!(n-k)!), the number of ways k objects can be chosen from a group of n. It can be pronounced "n choose k".
Answer:
4
Step-by-step explanation:
calculate the sum 4*1 any expression is multiplied by 1 remains the same solution is 4
Answer:
x=3
Step-by-step explanation:
A vertical line will have the equation in terms of x. Any point you choose on line <em>l </em>will have an x-coordinate of 3.
1)
evaluate when x = 6
5 + x
so when x = 6 then 5 + 6 = 11
answer
11
2)
2/6
in lowest term = 1/3 (divide top and bottom by 2)
3)
evaluate when x = 1
8 + x
so when x = 1 then 8 + 1 = 9
answer: 9
4)
14/48
lowest term = 7/24 (divide top and bottom by 2)
