In each case below, we describe a study to determine whether exercise helps increase certain mood enhancing chemicals in the brain. Indicate whether each describes an experiment or an observational study.
a). Using a random sample of 100 people, we randomly assign half of them to participate in a regular exercise program for a six-week period while the other half makes no changes. At the end of the time period, we measure the brain chemicals.
b). We contact a random sample of 100 people and record how much each person exercises and also measure the chemicals in the brain for each person.
Answers
Answer:
A)Experimental Study
B)Observational Study
Step-by-step explanation:
Observational Study : A study where researchers simply collect data based on what is seen and heard and infer based on the data collected.
Experimental Study: A study which involve the random assignment of -participants into different groups in order to determine the causal effect of a certain condition on a certain outcome .
A) In this case we are randomly classifying the subjects into two groups, where one group participate in a regular exercise program for a six week period, while the other half makes no changes. In this Part we are not observing the data . we are doing experiment over here and comparing those two different groups.
So, By definition It is an experimental study
B) In this case we are recording the data of each person and decision will be based on data
So, By definition It is an observational study
What is the inverse of the function f(x) = 1/4x – 12?
h(x) = 48x – 4
h(x) = 48x + 4
h(x) = 4x – 48
h(x) = 4x + 48
Answers
Answer:
h(x)=4x+48
Step-by-step explanation:
f(x) = 1/4x – 12
x=1/4y-12
x+12=1/4y
4x+48=y
h(x)=4x+48

Answers
Answer
25
Step-by-step explanation:
20/32 = 0.625
40 x 0.625 = 25
You can check by doing 25/40 and see if you get the same proportion (x/y)
25 is the correct answer 32/20 is 1.6 and 40/25 is also 1.6

1. A pitched roof is built with a 1:3 ratio of rise to span. If the rise of the roof is 10 meters, what is the span
Answers
Answer:
The answer is B) the span of the roof is 4
Step-by-step explanation:
The span is 30 meters if the pitched roof is built with a 1:3 ratio of rise to span.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We have:
A pitched roof is built with a 1:3 ratio of rise to span
rise/span = 1/3
rise = 10 meters
10/span = 1/3
span = 3×10 = 30 meters
Thus, the span is 30 meters if the pitched roof is built with a 1:3 ratio of rise to span.
