Answer:
115degrees
Step-by-step explanation:
Given the following angles
m<A=(7x+24)°
m<B=(7x-26)°
Since both angles are supplementary, their sum will be 180 degrees
Taking the sum of the angles
m<A + m<B = 180
7x+24 + 7x - 26 = 180
14x - 2 = 180
14x = 180+2
14x = 182
x = 182/14
x = 13
get m<A
m<A = 7x+24
m<A = 7(13) + 24
m<A = 91 + 24
m<A = 115
Hence the measure of angle m<A is 115degrees
72ab-36bc+48bd
Factor out 12b from the expression
12b x(6a-3c+4d)
Answer : 12b x(6a-3c+4d)
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).
