Step-by-step explanation:
I don't see any numbers, so I just give you an example :
<u>1</u>1
every position in a number is worth 10 times the value of the position to its very right.
so, in e.g. 11
the left 1 is worth 10 times the value of the right 1.
11
1 to the power of 2 is 1 and adding 10 would be 11
Answer:
4 7/12 ÷ 3 1/7 = 1 11/24
Step-by-step explanation:
First you want to make the mixed numbers improper fractions. So you take 4 7/12, and you mutiply 12 times 4 which is 48 and add the 7 which leaves us with 55 now turn that into a improper fraction... 55/12. And 3 1/7 as an improper fraction is 22/7. Now divide 55/12 ÷ 22/7 which is 1 11/24

Answer:
0.2301 = 23.01% probability that exactly 2 don't grow.
Step-by-step explanation:
For each seed planted, there are only two possible outcomes. Either it grows into a healthy plant, or it does not. The probability of a seed growing into a healthy plant is independent of any other seed, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
90% chance of growing into a healthy plant.
This means that
12 seeds are planted
This means that
What is the probability that exactly 2 don't grow?
So 12 - 2 = 10 grow, which is . Then
0.2301 = 23.01% probability that exactly 2 don't grow.
