Question 1 1 pts
1. A chemical engineer is trying to increase the amount of the useful product in a reaction,
She performs the reaction with her new equipment 10 times and gets the following
amounts of the useful product:
amount of useful
47.148.2 48.3 47.5 48.5 48.1 47 248.2 48.448.3
product in grams
What proportion of the reactions were above the 48 grams threshold?
2. Other chemists typically get 65% of their reactions to produce more than 48 grams.
Should the engineer say that she was able to increase the useful product when compared
to the other chemists?

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
