The answer is 9:16 just add 9+7=16 and then we know out of the 16 nine were dogs so 9:16
Answer:
Hope you got it....
Step-by-step explanation:
1=tan45∘
1=tan(22∘+23∘)
1=tan22∘+tan23∘1−tan22∘tan23∘
1−tan22∘tan23∘=tan22∘+tan23∘
1=tan22∘+tan23∘+tan22∘tan23∘
It will be the same for any two angles that add up to 45∘.
Answer:
2square root 10
Step-by-step explanation:
calculator
Here we have selected positive numbers from 2 to 18 so there are total 17 numbers with us.
Now the prime numbers between 2 and 17 are
2, 3, 5, 7, 11, 13, 17
So there are 7 prime numbers between 2 to 18
We have to find the probability of selecting prime numbers between 2 to 18
Probability = Outcomes of interest / All possible outcomes
Probability prime = 7/17
Probability prime = 0.4117
So probability of getting prime number is 0.4117
