A survey has a margin of error of +/- 4%. In the survey, 67 of the 110 people interviewed said they would vote for candidate A.
1 answer:
Answer:
option B
Step-by-step explanation:
given,
sample of person interviewed 110
people voted for A = 67
percentage of the person voted for A =
= 0.609
now, for all the people
= 0.609 x 9570
= 5829 people
now compensating the error
+ 4 % = 1.04 x 5829 = 6062 people
- 4 % = 0.96 x 5829 = 5596 people
so, the range of people voted for candidate A is
5596 to 6062 People
Hence, the correct answer is option B

Answer:
17
Step-by-step explanation:
Pythagorean theory baby! Okay so the Pythagorean theory is a² + b² = c² so lets draw a triangle and label our sides. So we know 8² + 15² = c² so I'm going to find the square root of all of our numbers. We get 64 + 225 = c² so then add 64 + 225 = 289 then I take the square root of 289 which equals 17 . This answer also makes sense because out hypotenuse should always be bigger then the legs.
I'm pretty sure thats right, Hope this helps.
Answer:
A
Step-by-step explanation:
To understand this, we can look at the vertical & horizontal translations of a parabola of the form
- A vertically translated parabola has the form
, where k is the vertical shift upward when k is positive and vertical shift downward when k is negative.
- A horizontally translated parabola has the form
, where a is the horizontal shift rightward when a is positive and horizontal shift leftward when a is negative.
When we replace x of the original function with (x-1), we have . According to the rules, this means that the original function is shifted 1 unit right (horizontal shift).
Correct answer is A.
