(fg)(x) = (3x + 6) (<span>2x^2)
</span>(fg)(x) = 6x^3 + 12x^2
hope it helps
The answer should be (49+25)-37 but in this case it is 49-37
No, this is not normal
This is a binomial distribution. Use BINS to determine if this is binomial.
B - binary?
I - independent?
N - number of trials
S - probability of success
B - yes, 3 or not a 3
I - yes, past rolls do not impact future rolls
N - 20 trials
S - prob success 1/6
Use binompdf on your calculator to find out the probability. To access, 2nd —> vars —> binompdf
Binompdf(20 (trials), 1/6 (p), 11 (x)) = 8.97x10^-5
The probability to roll a 3 11 times is .0000897. The chances are very low, making this not normal.
The answer is 4c-10
10 + 25 (35) is less than 40 - 10 (30)
For these you just plug in the value given for the variable (in this case, c) to each choice until you find the one is true
