F(x)=7x+7 and g(x)=6x^2 find (fg)(x)

$F(g(x))=7(6x^2)+7$ \\ We plug in our g(x) equation into f(x)
$F(g(x)) = 42x^2+7=0 \\ 
F(g(x)) = x^2=-1/6 \\ 
F(g(x)) = x = \sqrt \frac{-1}{6}i$

F(x) = 7x + 7; g(x) = 6x²

(fg)(x) = f(x) · g(x)

(fg)(x) = (7x + 7) · 6x² = (7x)(6x²) + (7)(6x²) = 42x³ + 42x²

Answer:

Megan needs a 95 to get an average of 90.

Step-by-step explanation:

Add up the test scores Megan has earlier, you would get 355 as a result of all scores added. In order to get an average of 90%, you would need to accumulate 450 points which she will need to take her final exam on it. Subtract 355 from 450 to get a score of 95% in which she will need that score to average it to 90%.

Assume that the probability that a baseball player will get a hit in any one at bat is 0.250. What is the probability that he wi

Answer: 0.0791

Step-by-step explanation:

Given : The probability that a baseball player will get a hit in any one at bat is 0.250.

Let x be the first hit.

According to the geometric probability , the probability that x (th) trial is the first success = $P(X=x)=(1-p)^{x-1}p$ , where p is the probability of getting success in each trial.

As per given p= 0.250

Then, the probability that he will get his first hit on his 5th at bat will be :

$P(X=x)=(1-0.25)^{5-1}(0.25)\\\\=(0.75)^4(0.25)\\\\=0.0791015625\approx0.0791$

Hence, the probability that he will get his first hit on his 5th at bat is 0.0791 .
