Answer: It would not be unusual to randomly select 11 people and find that greater than 9 recognize the famous brand name.
Step-by-step explanation:
Since we have given that
Mean = 6.2
Standard deviation = 0.51
Average number of people = 11
So, using the normal distribution, we get that
Now, we will check that
Hence, It would not be unusual to randomly select 11 people and find that greater than 9 recognize the famous brand name.
Answer:
Below.
Step-by-step explanation:
1) 245.
2) Approximate slope = -(245-200)/15 = -3.
Answer:
Step-by-step explanation:
Judging by the context, you are looking for the angle x of a triangle, where the other two angles are 76 and 49. The sum of a triangle's angles is always 180, so
76 + 49 + x = 180
125 + x = 180
x = 55
What’s the height?
Formula is: V= πr2h
d=4 in
r=2 in
V= π•2^2•h
V= π•4•h
If h is 3, answer is B. If h is 9, answer is C. Good luck.
Answer:
x = 8/3
Step-by-step explanation:
2x+4 = -x + 3 + 9
3x = 3 + 9 -4
3x = 8
x = 8/3
