Answer:
g(f(x)) =75x² + 90x + 30
Step-by-step explanation:
To find g(fx), all we need to do is to insert f(x) in g(x), that is anywhere x is in g(x), we replace the value of g(x) with x and then simplify
f(x) = 5x + 3 g(x) = 3x² + 3
g(f(x)) = 3(5x + 3)² + 3
Next is to open the parenthesis and then simplify
(5x + 3)² = (5x + 3)(5x + 3) = 5x(5x+3) + 3(5x+3) =25x² +15x +15x+9 = 25x²+30x+9
g(f(x)) = 3(25x² + 30x + 9) + 3
g(f(x)) = 75x² + 90x + 27 + 3
g(f(x)) =75x² + 90x + 30
Answer:
A food distribution company has employees that order food supplies for local restaurants by predicting sales. It is important that the employees order the correct amount of food. If they order too much, the food will spoil. If they don’t order enough, the restaurant will not get the food they need. The company pulls an SRS of 500 orders and finds that 408 of the orders were correct. Calculate and interpret a 95% confidence interval for the proportion of all orders that were correct.(4-step process)

Answer:
C
Step-by-step explanation:
I think, the formatting is a bit weird and I don't see an A option, but 52 and 212 are not mixed numbers, but 2.3 can be written as 2 3/10 and etc so it is!
Well. add all of these up 8+5+5. we know 5+5 is 10. and 10+8 is 18. so 18 is the denominator. There are 8 red markers and 5 blue markers at 8 and 5 up. 8+5 is 13 right? So the numerator will be 13. but the probability of picking a blue then a red is 13 alone or if you are ask for out of the amount of markers there are, its 13/18. so the probability is 13 or 13/18.
