Answer: 0.444
Step-by-step explanation:
Given : Total burritos ordered = 15
Number of burritos with hot peppers =5
Number of burritos without hot peppers=10
Then the probability that the burrito has hot peppers:-
![\dfrac{5}{15}=\dfrac{1}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7B5%7D%7B15%7D%3D%5Cdfrac%7B1%7D%7B3%7D)
Using binomial probability formula:-
![P(X)=^nC_xp^x(1-p)^{n-x}](https://tex.z-dn.net/?f=P%28X%29%3D%5EnC_xp%5Ex%281-p%29%5E%7Bn-x%7D)
If you pick three burritos at random , then the probability of getting having exactly one burrito with hot peppers:-
![P(1)=^3C_1(\dfrac{1}{3})^1(\dfrac{2}{3})^{2}\\\\=(3)\dfrac{1}{3})^1(\dfrac{2}{3})^{2}=0.444444444444\approx 0.444](https://tex.z-dn.net/?f=P%281%29%3D%5E3C_1%28%5Cdfrac%7B1%7D%7B3%7D%29%5E1%28%5Cdfrac%7B2%7D%7B3%7D%29%5E%7B2%7D%5C%5C%5C%5C%3D%283%29%5Cdfrac%7B1%7D%7B3%7D%29%5E1%28%5Cdfrac%7B2%7D%7B3%7D%29%5E%7B2%7D%3D0.444444444444%5Capprox%090.444)
Hence, the required probability = 0.444
Okay so you would subtract the 30 to get 210 then divide the 210 by 14 to get 15 so your inequality
![15\geq x](https://tex.z-dn.net/?f=15%5Cgeq%20x)
your original inequality is ![240\geq 30+14x](https://tex.z-dn.net/?f=240%5Cgeq%2030%2B14x)

Step-by-step explanation:
Just multiply the numbers
Answer:
119
Step-by-step explanation:
Angle C= 62
So you add 62 + 57 which gives you 119
All angles must add up to 180 so you subtract 119 from 180 which gives you 61
Since angle A is 61 and a straight line angle is 180 you subtract 61 from 180 to give you angle B
180 - 61 = 119
therefore your answer is 119
