i just graphed it and the point in which they intersect s the x and y values. Hope this helped Happy Holidays
Step-by-step explanation:
Multiply to remove the fraction, then set equal to
0 and solve.
Inequality Form:
b<48.59
Interval Notation:
(−∞, 48.59)
Given:
A random survey of 30 students found that 17 played a musical instrument.
Total number of students = 450
To find:
Estimated number of students who do not play an instruments.
Solution:
A random survey of 30 students found that 17 played a musical instrument.
Let E be the event that student play an instrument.
So, probability that a student plays an instrument is
![P(E)=\dfrac{17}{30}](https://tex.z-dn.net/?f=P%28E%29%3D%5Cdfrac%7B17%7D%7B30%7D)
Probability that a student do not play an instrument is
![P(E')=1-P(E)](https://tex.z-dn.net/?f=P%28E%27%29%3D1-P%28E%29)
![=1-\dfrac{17}{30}](https://tex.z-dn.net/?f=%3D1-%5Cdfrac%7B17%7D%7B30%7D)
![=\dfrac{13}{30}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B13%7D%7B30%7D)
Now, number of students who do not play an instruments is
![450\times P(E')=450\times \dfrac{13}{30}](https://tex.z-dn.net/?f=450%5Ctimes%20P%28E%27%29%3D450%5Ctimes%20%5Cdfrac%7B13%7D%7B30%7D)
![450\times P(E')=195](https://tex.z-dn.net/?f=450%5Ctimes%20P%28E%27%29%3D195)
Therefore, 195 students do not play an instrument.
Assuming that you mean 100cm in length, I think I know the answer, but message me if I’m wrong so that I can correct myself!!!
Volume is L • W • H where L is length, W is width, and H is height.
To find the volume you have to multiply all the dimensions, so 100 * 30 * 12 = 36,000, and since its 3 dimensional we use cm^3 which is centimetres cubed.
