Answer:
Introducing a change to the subgroup
Step-by-step explanation:
Given there are four statements. We have to find the one which represents one of the differences between an experiment and an observational study.
The answer is option 2. Introducing a change to the subgroup
Experimental and observational studies are both types of studies between which a number of differences can be identified. When conducting research studies, various types of research in order to arrive are adopted according to the need.
An experimental study is a study where the researcher has control over most of the variables.
On the other hand, an observation study is a study where the researcher cannot control any variable but merely observes the subject without controlling any variables.
Answer:
14.02
Step-by-step explanation:
You'd have to write equations for the price per month for each club.
Let x equal the number of months of membership, and y equal the total cost.
Club A's is y = 24x + 21.50 and Club B's is y = 17.25 x + 41.00 Because we know that the prices, y , would be equal, we can set the two equations equal to each other.
24x + 21.50 =17.25 x+ 41.00
subtract 21.50 both sides
. We can now solve for x by isolating the variable.
24x=17.25x+19.5
divide 17.25x
1.39x=19.5
divide 1.39 both sides
x=14.02
After five months, the total cost would be the same.
Answer:
about 117 times
Step-by-step explanation:
No. of possible outcomes of a cube: 6
2 out the 6 possible outcomes are less than 3,
and therefore, No. of favorable outcome: 2
P(less than 3)= No. of favorable outcome / No. of possible outcomes
=2/6 => 1/3
if you roll a standard number cube 350 times then,
Prediction= number of rolls x (P(less than 3))
=350 x 1/3
≈117 times.
