Oliga [24]

Answer:

Experiment

Step-by-step explanation:

An observational study is a study where researchers simply collect data based on what is seen and heard and make inferences based on the data collected.

Whereas, Experimental studies are the ones where researchers introduce an intervention and study the effects.

Giovanna did not just collect data alone and make inferences based on the collected data, as is done during an observational study, but she studied the effects of the data that she collected by calculating the average driving duration for each route.

Hence we see that she conducted an Experimental study.

At a school pep rally the ratio of students who wore red to those who wore yellow is 7 to 3 their are 300 students at the rally
Serhud [2]
Red to yellow.......7:3....added = 10
so 7/10 of the total students wore red and 3/10 of the total students wore yellow

and there are 300 total students...
7/10(300) = 2100/10 = 210 wore red
3/10(300) = 900/10 = 90 wore yellow

how many more wore red.....(210 - 90) = 120 more students wore red then yellow

Write the equation, in standard form, for the following relation. B = {(x, y ): (2, 3), (4, 4), (6, 5), . . .}
Rashid [163]
(2,3)(4,4)
slope = (4 - 3) / (4 - 2) = 1/2

y = mx + b
slope(m) = 1/2
(2,3)...x = 2 and y = 3
sub and find b, the y int
3 = 1/2(2) + b
3 = 1 + b
3 - 1 = b
2 = b

ur equation is : y = 1/2x + 2...but we need it in standard form

y = 1/2x + 2
-1/2x + y = 2 ...multiply by -2
x - 2y = -4 <== standard form
