Answer:
This study is an experiment
The response variable is the level of reaction (how excited they were) of the two groups after seeing their various shows and the explanatory variable are the two shows that was manipulated by the researchers.
Step-by-step explanation:
An observational study is a study where researchers collect data based on what is seen and heard and conclude based on the data collected. The researcher has no control over the variables, while an experiment is a method of applying treatments to a group and recording the effects of such treatments.
This study is an experiment because the researchers had control over the variables by manipulating the variables: showing Episode 1 of Season 8 to half of them and showing Episode 1 of Season 1 of a new comedy show to the other half. The response variable is the level of reaction (how excited they were) of the two groups after seeing their various shows and the explanatory variable are the two shows that was manipulated by the researchers.
Answer:
1st question answer is 10cm2
2nd question answer is 1368 in2
3rd question answer is 45 in2
Step-by-step explanation:
1st question explanation is 16+ 24 = 40
2nd question explanation is 19 x 8 x 9 = 1368

Answer:
7 is what percent of 30
is = 7
of = 30
% = x
Step-by-step explanation:
x/100 = 7/30
cross multiply
(30)(x) = (7)(100)
30x = 700
x = 700/30
x = 23 1/3% or 23.33%

Answer:
N÷4×K
Step-by-step explanation:
It would be easy to explain if the unknown numbers had values
The first thing you should know is that the slope of the line that passes through two points, by definition is given by:
m = (y2-y1) / (x2-x1)
Substituting the values we have:
m = (76-70) / (28-30)
m = -3
answer:
the slope of the line between points a and b is
m = -3
