The experiments on new drugs a and b revealed proportions of their significant efficiency as pˆa=0.73 and pˆb=0.84 (of all the tests). the margin of error is 0.07 and is the same for both of the data samples. use this information to give a range of plausible values for the proportions for a 95% confidence interval.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

answer: 7. if the functions had a negative leading coefficient and is of even degree, which statement about the graph is true?

step-by-step explanation:

y= -2x+4, have a great day
