Answer:
9 times
Step-by-step explanation:
The best way to go about this is to give actual figures
Let us consider rectangular shape
Let us have a rectangle with dimensions 6 m by 12 m
The area will be 6 * 12 = 72 m^2
The shape having a similar dimension would have dimensions 12m by 36 m
So its area will be ;
18 * 36 = 648 m^2
So we finally proceed to make a division
Mathematically, that will be 648/72 = 9
So the area will be in the ratio of 1 to 9
Answer:
Option c
Step-by-step explanation:
You just multiply g(x) and f(x) together and it gives you C :)
Answer: b) 84
Step-by-step explanation:
Let p be the prior estimate of the required proportion.
As per given , we have
p =0.5 (The probability of getting heads on a fair coin is 0.5)
Significance level :
Critical z-value (using z-value table ) :
Confidence interval width : w= 0.18
Thus , the margin of error :
Formula to find the sample size ( if prior estimate of proportion is known.):-
Substitute the values , we get
Simplify ,
[Round of to the next whole number.]
Hence, the number of times we would have to flip the coin =<u>84</u>
hence, the correct answer is b) 84
