Answer:
The function is
g(x) = 5^(-x)
This question can be easily solved by using a graphing calculator
and plotting the graph of g(x)
In the image below, we can see that for each value of x , there is a corresponding value for g(x)
This means that the function does not have any discontinuities. Therefore,
The domain of g(x) is all real numbers (x ∈ R)
The range is related to the values that can be achieved by g(x),
Since it is a positive exponential function, all values will be g(x)>0
And the range would be (0,∞)
Answer is 13+21 , two negatives make a positive as a result the answer is A
Answer:
7x -2y
Step-by-step explanation:
5x−4y+2(y+x)
Distribute
5x -4y +2y +2x
Combine like terms
5x +2x -4y +2y
7x -2y
Answer:
E(x) = 1.43 (Approx)
Step-by-step explanation:
Given:
Total number of camera = 7
Defective camera = 5
Sample selected = 2
Computation:
when x = 0
P(x=0) = 2/7 × 1/6 = 2/42
P(x=1) = [2/7 × 5/6] + [5/7 × 2/6] = 20/42
P(x=2) = 5/7 × 4/6 = 20/42
So,
E(x) = [0×2/42] + [1×20/42] + [2×20/42]
E(x) = 1.43 (Approx)
