Answer:
a) Unit: College Student
Variables of measurement: Procrastination and illness habits.
b) Unit: SUV cars
Variables: Manufacturing and car damage for two car manufactures.
Step-by-step explanation:
We are given the following in the question:
In a research, a unit is a single individual or object that is measured.
a) A study finds that college students who often procrastinate tend to be sick more often than students who do not procrastinate.
Since college students are asked about procrastination, then the unit in this study is college students.
Unit: College Student
Variables of measurement: Procrastination and illness habits.
b) A study finds that sport utility vehicles (SUVs) made by one car manufacturer tend to be more heavily damaged in a crash test than SUVs made by a second car manufacturer.
Since all SUVs cars are considered, the unit in this research is SUV cars
Unit: SUV cars
Variables: Manufacturing and car damage for two car manufactures.
Plug it in
y = 2/3(24 - -10/3) + 5(-10/3)y
y = 2/3 (82/3) + 5(-10/3)y
y = 164/9 - 50/3y
because there are “y” values on both sides, they cancel out, leaving a number to equal another number. this does not make any sense. therefore, there is no solution to this equation when x = -10/3.
A motorist drove 150 miles in the morning and;
50 miles in the afternoon
His average rate in the morning was twice his average rate in the afternoon
He spent 5hrs driving
Let the times spent driving in the morning be x
Average speed = Distance ÷ time
= 2(
)
Cross multiplying gives;
750 - 150x = 100x
250x = 750 , x =3
Average speed in the morning is 150/3 = 50miles/hr
Average speed in the afternoon = 50/(5-3) = 25miles/hr
