Step-by-step explanation:
Given the equations as
f(x)=2x and
g(x)=2^x
Using a graph tool the equations will intersect at points (2,4) and (1,2)
x =2 or x=1
Answer:
True
Step-by-step explanation:
<u><em>Explanation</em></u>:-
The equation of the standard hyperbola is
- Center is (0,0)
- Hyperbola is symmetric with respective to both the axes, since if (x, y) is a point on the hyperbola, then (-x, y), (-x,-y), (x,-y) are also lie on the parabola.
- The relation of between focus and transverse and conjugate axes c²=a²+b²
- The transverse axis is along x-axis
- The conjugate axis is along y-axis
- The length of transverse axis is 2 a
- The length of conjugate axis is 2 b
- The foci is (±c,0) and the equation of foci is x=±a e)
- The length of Latus rectum is
Answer:
The probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47
Step-by-step explanation:
Has Gained Weight Has Not Gained Weight
Does not take vitamins 52 19
Takes one vitamin per day 35 49
Takes more than one vitamin per day 72 80
We are supposed to find the probability that he or she has gained weight, given that he or she takes more than one vitamin per day
A= he or she has gained weight
B=he or she takes more than one vitamin per day
B = 72+80=152
So,
So, Option C is true
Hence the probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47
