Answer:
![\frac{3}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B14%7D)
Step-by-step explanation:
Total Students = 28
Brown Hair = 22
NOT Brown Hair = 28 - 22 = 6
The probability of an event is the number of that event divided by total number.
So, let denote probability of without brown hair be P(NOT BROWN). So, we can say:
P(NOT BROWN) = 6/28
Reducing, we get:
P(NOT BROWN) = 3/14
Answer:
-3
Step-by-step explanation:
To get the slope of the line tangent to the function y = 6 - 3x
First, we need to differentiate;
dy/dx = 0 -3x^{1-1}
dy/dx = 0 - 3x^0
dy/dx = 0 - 3
dy/dx = -3
Hence the slope of the line tangent to the function at the point is -3
Answer:
![(x+5)^{2} +(y+4.7)^{2} = 274](https://tex.z-dn.net/?f=%28x%2B5%29%5E%7B2%7D%20%2B%28y%2B4.7%29%5E%7B2%7D%20%3D%20274)
Step-by-step explanation:
Put the xs together
![x^{2} +26x + y^{2} -22y+274=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B26x%20%2B%20y%5E%7B2%7D%20-22y%2B274%3D0)
move the 274 to the other side, and that will be the ![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
![x^{2} +26x + y^{2} -22y=274](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B26x%20%2B%20y%5E%7B2%7D%20-22y%3D274)
you need
and ![y^{2}](https://tex.z-dn.net/?f=y%5E%7B2%7D)
so square root 26 is 5.09, so about 5 when rounded
![(x+5)^{2}](https://tex.z-dn.net/?f=%28x%2B5%29%5E%7B2%7D)
and square root 22 is 4.69, so about 4.7 when rounded
![(y+4.7)^{2}](https://tex.z-dn.net/?f=%28y%2B4.7%29%5E%7B2%7D)
so ![x^{2} +26x + y^{2} -22y+274=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B26x%20%2B%20y%5E%7B2%7D%20-22y%2B274%3D0)
becomes ![(x+5)^{2} +(y+4.7)^{2} = 274](https://tex.z-dn.net/?f=%28x%2B5%29%5E%7B2%7D%20%2B%28y%2B4.7%29%5E%7B2%7D%20%3D%20274)
Answer:
The volume of box Y is 1/64 of the volume of box X
Step-by-step explanation:
Since. The edge of a box Y is 1/4 the lengtj of box X ;
The volume is 3 dimensional and each dimension of Y is 1/4th the dimension of X
The volume of Y will be (1/4)^3 the volume of Y
(1/4)^3 = 1/4 * 1/4 * 1/4 = 1/64
For instance, if edge of X = 8
Edge of Y which is 1/X ; edge Y = 1/4(8) = 2
Volume, X 8^3 = 512
Volume Y = 2^3 = 8
8/512 = 1 / 64
