Answer:
C is not a zero for the solution of the polynomial equation
Please slow down with posting questions, this seems like a Canvas Exam.
Answer:
{2, 3, 4, 5}
Step-by-step explanation:
3x + 1 > 4
3x > 3
x > 1.
If x = 1 the inequality is not true,
- but 2 3 4 and 5 will make the inequality true.
Answer:
use the pythagoras theorem
Step-by-step explanation:
Answer:
1,524 centimeters
Step-by-step explanation:
Multiply 50 by 12. 50 * 12 = 600 inches
Multiply 600 by 2.54 to get the number of centimeters. 600 * 2.54 = 1,524
Answer:
The statement that "the margin of error was given as 
percentage points" means that the population proportion is estimated to be with a certain level of confidence, within the interval 
; where ![\hat{p}[tex] is the sample's proportion. The correct answer is C. The statement indicates that the interval [tex]0.14\pm0.05](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%5Btex%5D%20is%20the%20sample%27s%20proportion.%3C%2Fp%3E%3Cp%3E%20%3C%2Fp%3E%3Cp%3EThe%20correct%20answer%20is%20C.%20The%20statement%20indicates%20that%20the%20interval%20%5Btex%5D0.14%5Cpm0.05)
is likely to contain the true population percentage of people that prefer chocolate pie.
Step-by-step explanation:
The margin of error for proportions is given by the following formula:
Where:
is the critical value that corresponds to the confidence level; the confidence level being 
,
is the sample's proportion of successes,
is the size of the sample.
In this exercise we have that 
and that the margin of error is 0.05.
Therefore if we replace in the formula to calculate the confidence interval we get:
Which means that the true population proportion is estimated to be, with a certain confidence level, within the interval (0.09, 0.19).
