HELP ASAP Ten Christmas-light bulbs, each with a resis-
tance of 17.1 k 2, are connected in parallel
to 120 V household current. What is the total
resistance of the circuit, the total current, the
current through each bulb, and the voltage
in each bulb?

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Which value of m will create a system of parallel lines with no solution? y= mx - 6 8x - 4y = 12

Stu and ambrose are working together on a study of whether diet is related to students' mental health. first, they randomly select 10 students from the student center and 10 students from the office of counseling and psychological services. then, they ask students to rate their diet in terms of healthiness on a scale of 1-100 before completing a 20-item mental health survey. a) name one of the constructs being studied b) how was the construct you named above operationally defined in this experiment? e) was the variable you described above their independent variable, their dependent variable, or a controlled variable? d) what is a confounding variable? what is a potential confound in this study?
