We know that
see the picture to better understand the problem
in the right triangle ABC
Applying the Pythagoras Theorem
AB²=BC²+AC²-------> BC²=AB²-AC²
AB=8 ft
AC=4 ft
BC²=8²-4²-----> BC²=48--------> BC=√48-------> BC=6.93 ft
the answer is6.93 ft
Answer:
social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2%
Sample size 'n' = 625
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given data Apple launches an ad campaign for iPhone 12
Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign
probability of positive reactions p = 1/2
Probability of negative reactions q = 1-p = 1/2
we know that 
<u><em>Step(ii):</em></u>-
Given margin of error = 2 % =0.02
The margin of error is determined by
√n = 25
squaring on both sides, we get
n = 625
Answer:
144
Step-by-step explanation:
The ratio of men to women working for a company is 8 to 5.
Total men and women working as per the ratio is 8+5 = 13
So the ratio of men to total is
the ratio of women to total is
there are 234 employees total
To find the number of men works , we make a proportion
Cross multiply it
8 * 234 = 13x
1872 = 13x
Divide by 13 on both sides
x= 144
Answer: b = 20 c = 160
Step-by-step explanation:
the value of a straight angle is 180, so 180-20= 160
