The Median of this data set is 9.
Hope this helps.
The wiggly line is a function and the circle thingy is relation since it does not pass the line test
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.
The surface area of a regular tetrahedron with edge length s is
... A = (√3)s²
For your edge length of 4 inches, the surface area is
... A = (√3)(4 in)² = 16√3 in²
Answer:
C
Step-by-step explanation:
One side;
7 x 8 = 56, the side parallel to it is also 56 as well, so 56(2).
Second(bottom) side;
8 x 4 = 32, the side parallel to it(the side above) is also 32 as well, so 32(2).
Third(front) side;
4 x 7 = 28, the side parallel to it(backside) is also 28 as well, so 28(2).
You add all those products to get the surface area:
<em>56(2) + 32(2) + 28(2)</em>
