Answer:
9
Step-by-step explanation:
6 times 3 = 18
27- 18 = 9 brandon is 9
0.09 is the answer, hope this helps
I Think The Answer Is 140.
The Expression: 0.8x + x = 252 Can Explain The Answer If x = 140.
Or: 1.8 Times x = 252 If x = 140.
Answer:
B. The observational study is a cross-sectional study because information is collected at a specific point in time.
Step-by-step explanation:
1) There are three types of Observational Studies: Case-control, cross-sectional and Cohort.
2) Since the researchers collected information from those 1800 adults at a certain time, then we can call it a cross-sectional study. It does not provide solid results since the research was not done over a period to collect further information. We don't know, for example, much more than what that association deeply mean.
3) If we wonder more, then the researchers would have to track those adults over a given period, i.e. a Cohort would be necessary.
4) Moreover, it's not "retrospective" for virtually every question, always makes us look back somehow, and it does not categorize a kind of observational study.
The probability that jim will win = P(A) = 1/9
<h3>What is probability?</h3>
The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
<h3>According to the given information :</h3>
The odds in favor of jim beating a friend at golf are = 1:8
Let A be the event that Jim beating a friend golf.
So,
according to ratio, it becomes
P(A)/P(A') = 1/8
P(A) = 1x
P(A') = 8x
we know that :
P(A) + P(A') = 1
x + 8x = 1
9x = 1
x = 1/9
so that
P(A) = 1/9
P(A') = 8/9
the probability that jim will win = P(A) = 1/9
