Answer: The required probability is 0.674.
Step-by-step explanation:
Since we have given that
Number of students in the Spanish class = 38
Number of students in the French class = 27
Number of students in the German class = 16
Number of students in both spanish and French = 14
Number of students in both Spanish and German = 6
Number of students in both French and German = 5
Number of students in all three class = 2
So, it becomes:
![n(S\cup F\cup G)=n(S)+n(F)+n(G)-n(S\cap F)-n(G\cap F)-n(S\cap G)+n(S\cap F\cap G)\\\\n(S\cup F\cup G)=38+27+16-14-5-6+2=58](https://tex.z-dn.net/?f=n%28S%5Ccup%20F%5Ccup%20G%29%3Dn%28S%29%2Bn%28F%29%2Bn%28G%29-n%28S%5Ccap%20F%29-n%28G%5Ccap%20F%29-n%28S%5Ccap%20G%29%2Bn%28S%5Ccap%20F%5Ccap%20G%29%5C%5C%5C%5Cn%28S%5Ccup%20F%5Ccup%20G%29%3D38%2B27%2B16-14-5-6%2B2%3D58)
So, Probability that he or she is taking at least one language class is given by
![\dfrac{58}{86}=0.674](https://tex.z-dn.net/?f=%5Cdfrac%7B58%7D%7B86%7D%3D0.674)
Hence, the required probability is 0.674.
Answer:
g or h whichever u think is best
Step-by-step explanation:
Answer: a. 1759.52 radians/minutes
b. 1407.62 feet/minutes
Step-by-step explanation:
Diameter = 1.6 feet
Radius = Diameter/2= 1.6/2 = 0.8 feet
N = 280 revolution
a. Angular speed(w) = 2πN
= 2π × 280
= 560π
= 560 × 3.142
= 1759.52 radians/minutes
Speed of cyclist = wr
= 1759.52 × 0.8
= 1407.62 feet/minutes
Answer:
40.81 centimeters is the corrects answer. use addition to add them all together
