A number from 1-100 is randomly selected. What is the probability that it is a perfect square, given that it is an odd number?
coldgirl [10]
Events:
1 ≤ n ≤ 100
A=x is a perfect square, i.e. x=n^2
B=x is odd, i.e. n is odd
P(A|B)
=P(A∩B)/P(B)   by definition of conditional probability
(reads Probability that the number is a perfect square given that it is odd)

Since there are 10 perfect squares between 1 to 100 (1,4,9,16,25,36,49,64,81,100), out of which 5 are odd {1,9,25,49,81)
So P(A∩B)=5/100
P(B)=probability of odd x  {1,3,5,7,.....95,97,99}
= 50/100=1/2
Therefore 
P(A|B)=(5/100)/(1/2)=1/10

I need help with the slope of this line.​
GrogVix [38]
The slope is 0.




The formula to find the slope is y2-y1 over x2-x1. If you plug in your numbers, you should have 5-5 over 9-10. Subtract this and you will get your slope!

Think about the graphs of the equations in the following system. x2+ y2 = 2 y = 2x2 – 3 Which of the following describes the sys
Feliz [49]

circle: x2+ y2 = 2  

parabola: y = 2x2 – 3

 

The standard form of equation of circle is:

( x – h )^2 + ( y – k )^2 = r^2

We are given the equation x^2 + y^2 = 2.

Where h and k are the x and y coordinates of the center. Basing on the standard equation, the center is at (0 , 0) and r = \sqrt{2}

 

The standard form of equation of parabola with the axis of symmetry parallel to the y-axis is:

(x - h)^2 = 4p (y - k)

Rearranging the given equation into this form:

x^2 = (½) y + 3/2

x^2 = ½ (y + 3)

Since 4p is positive value, therefore the parabola is opening up. The vertex is located at (0 , -3).
