[will mark as brainliest if correct] a group of doctors conducted an experiment to determine which drug is more effective in the treatment of hypertension. two drugs were tested across three hospitals on 50 patients each. the following table shows the number of patients that reported improvement in hypertension symptoms in each hospital. | hospital | | drug x | | drug y | a 29 30 b 35 21 c 26 18 select all true statements that can be concluded from the experiment. a.) drug y's claim to improve the symptoms of hypertension is true. b.) drug x's claim to improve the symptoms of hypertension is true. c.) there is not enough information to make any conclusions about the experiment. d.) the percentage of patients showing improvement is higher in drug y e.) drug y is more effective than drug x because there is a greater percentage of patients that showed an improvement f.) drug x is more effective than drug y because there is a greater percentage of patients that showed an improvement

I believe the correct answers are A, B, and F

Step-by-step explanation:

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
