Answer: 113, 57, and 66
Step-by-step explanation:
The sum of all of the interior angles can be found using the formula S = (n - 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.
Answer:
2/3
Explanation:
Given the below;
![\frac{-14}{9}\times\frac{(-3)}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B-14%7D%7B9%7D%5Ctimes%5Cfrac%7B%28-3%29%7D%7B7%7D)
We can see from the above that 9 is divisible by 3 and that 14 is divisible by 7, let's go ahead and reduce to the lowest term as shown below;
The answer here is no solution
Answer: Hence, the probability that he will get at least one lemon is 0.70.
Step-by-step explanation:
Since we have given that
Number of cars = 30
Number of lemon cars = 10
Number of other than lemon cars = 30-10 = 20
According to question, he bought 3 cars,
we need to find the probability that you will get at least one lemon.
So, P(X≤1)=1-P(X=0)=1-P(no lemon)
Here, P(no lemon ) is given by
![\dfrac{20}{30}\times \dfrac{20}{30}\times \dfrac{20}{30}=(\dfrac{20}{30})^3](https://tex.z-dn.net/?f=%5Cdfrac%7B20%7D%7B30%7D%5Ctimes%20%5Cdfrac%7B20%7D%7B30%7D%5Ctimes%20%5Cdfrac%7B20%7D%7B30%7D%3D%28%5Cdfrac%7B20%7D%7B30%7D%29%5E3)
so, it becomes,
![P(X\geq 1)=1-(\dfrac{20}{30})^3=1-(0.67)^3=0.70](https://tex.z-dn.net/?f=P%28X%5Cgeq%201%29%3D1-%28%5Cdfrac%7B20%7D%7B30%7D%29%5E3%3D1-%280.67%29%5E3%3D0.70)
Hence, the probability that he will get at least one lemon is 0.70.
The last one 7(30)-7(7) because if you do it then it is 7(23) which doesn’t make sense because it is 27 we need to find
