Corsi et al. (2007) conducted a study of the factors mediating whether injection drug users enter a drug treatment program. in their sample of 491 drug users, 38.1% were single; 27.5% were married or had a partner; and 34.4% were divorced, separated, or widowed. of the drug users who actually entered a treatment program, 67 were single; 66 were married or had a partner; and 61 were divorced, widowed, or separated. what kind of statistical chi-square test should corsi use to analyze the data?

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

=240

step-by-step explanation:

i believe it's a.

i'm not sure on this one, most likely correct.

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
