Answer:
110
Step-by-step explanation:
y = 11/6x where x is in minutes
there are 60 minutes in an hour
plug in 60 as x
11/6 *60 = 11*10 = 110
Answer:
21.98 is the circumference because is it 7 pi 7 times 3.14. For the area though it is 38.48 because you need to get the radius of the circle and you divided 7 by 2 which is 3.5 and here is the work A=πr2=π·3.52≈38.48451
Step-by-step explanation:
Hope this helped and you understood if you want it would help a lot if you put it brainliest.
B. You can get this by factoring the bottom of the first expression and then cancelling the terms. Then multiply by the inverse of the second.
Answer:
probability that the child DOES NOT play the piano
![P(E^{-}) =\frac{4}{5}](https://tex.z-dn.net/?f=P%28E%5E%7B-%7D%29%20%20%3D%5Cfrac%7B4%7D%7B5%7D)
Step-by-step explanation:
A students' choir contains 25 children
n(S) =25
The number of students play the piano =5
Let 'E' be the event of the child play the piano so n(E) =5
The probability of that the child play the piano
![P(E) = \frac{n(E)}{n(S)}](https://tex.z-dn.net/?f=P%28E%29%20%3D%20%5Cfrac%7Bn%28E%29%7D%7Bn%28S%29%7D)
![P(E) = \frac{5}{25}= \frac{1}{5}](https://tex.z-dn.net/?f=P%28E%29%20%3D%20%5Cfrac%7B5%7D%7B25%7D%3D%20%5Cfrac%7B1%7D%7B5%7D)
Let 'E⁻ be the event of the child play does not play the piano
![P(E^{-}) = 1- P(E)](https://tex.z-dn.net/?f=P%28E%5E%7B-%7D%29%20%3D%201-%20P%28E%29)
![P(E^{-}) = 1- \frac{1}{5} =\frac{4}{5}](https://tex.z-dn.net/?f=P%28E%5E%7B-%7D%29%20%3D%201-%20%5Cfrac%7B1%7D%7B5%7D%20%3D%5Cfrac%7B4%7D%7B5%7D)
<u>Conclusion</u>:-
probability that the child DOES NOT play the piano
![P(E^{-}) =\frac{4}{5}](https://tex.z-dn.net/?f=P%28E%5E%7B-%7D%29%20%20%3D%5Cfrac%7B4%7D%7B5%7D)
Let A and 4A be the investment amounts.
The total profit is 3480=0.06A+0.20A=0.26A, so Fund A investment, A=3480/0.26=$13384.62, and Fund B is $53538.46.
