Step-by-step explanation:
Since
The function has a constant factor so we have a exponential function.
The equation of a exponential function is
Where a is the initial value and b is the growth factor
The growth factor is 3/2,
The initial value in 32
Plug in 4 for x.
You will get 162
Plug in 5 for x you will get
243.
2013- 162
2014- 243
Answer:
Step-by-step explanation:
we know that
In the circle of the figure the radius is equal to 2 units
The distance from the center of the circle (origin) to the point A must be same at the radius
so
Applying the formula's distance between two points
point A( 1,y) and point (0,0)
the formula to calculate the distance between two points is equal to
substitute the values
rewrite
Solution: We are given an urn contains 1 red chip and 1 white chip.
Now let's consider the first draw.
The probability of drawing red chip
We know that if the first chip drawn is red, we will put back that chip into the urn with additional two red chips. So if the first chip drawn is red, we will have 3 red chips and 1 white chip in the urn.
Now if we draw another chip from an urn containing 3 red chips and 1 white chip. Then the probability of drawing a red chip is
Now lets combine these two events
The probability of both are red = P(1st draw is red) . P(2nd draw is red)
=(1/2) x (3/4)
=(3/8)
Therefore, the probability of both selections are red is 3/8
