If f(x) =5x-2 and g(x) = 2x +1 find(f+g)(x)

Mathematics

Gala2k [10]3 years ago
6 0

Answer & Step-by-step explanation:

When we see (f + g)(x), it means that we are going to be adding f(x) to g(x).

<em>f(x) = 5x - 2</em>

<em>g(x) = 2x + 1</em>

(f + g)(x) = (5x - 2) + (2x + 1)

Combine like terms.

(f + g)(x) = 7x - 1

So, (f + g)(x) equals 7x - 1

Find the probability of having 2, 3, or 4
denis-greek [22]

Answer:

16% for 2 successes, 6.4% for 3 successes, 2.6% for 4 successes, and 1% for 5 successes

Step-by-step explanation:

Since the success rate of a binomial experiment is 40%, converted to 0.4, you get the equation of f(x) = (0.4)^x, for where x is the amount of successful experiments

For the success of 2 experiments:

f(2) = (0.4)^2

     =0.16 => 16%

For the success of 3 experiments:

f(3) = (0.4)^3

     = 0.064 => 6.4%

For the success of 4 experiments:

f(4) = (0.4)^4

     = 0.0256 => 2.56% => ~2.6

For the success of 5 experiments:

f(5) = (0.4)^5

     = 0.01024 => 1.024% => ~1%
