Answer:
x = 139º
Step-by-step explanation:
A line = 180º
180º - 41 º = 139º
-0.25 would be -25/100 which can be reduced to -1/4
Answer: A) 52 ft B) $134.68
Step-by-step explanation:
First find the surface area by multiplying the dimensions together.
2 x 4 = 8
2 x 3 = 6
4 x 3 = 12
Then add them up and multiply by two because there are two of each side.
26 x 2 = 52
To find the cost, multiply 52 by $2.59 to get the price.
52 x $2.59 = $34.68
The sample size must be 543 so the sample proportion is will not differ by 5%
We are given the following in the question:
Margin of error = 5%
Confidence interval:
p ±z√(p'(1 - p')/n)
Margin of error =
p = ±z√(p'(1 - p')/n)
Since no particular proportion is given, we take
p' = 0.5
Z critical at α 0.02 is ± 2.33
Putting values, we get,
p = ±z√(p'(1 - p')/n)
2.33 x √(0.5(1 - 0.5)/n)
√n = 2.33x 0.5/0.05
n = 542.89 = 543
Thus, the sample size must be 543 so the sample proportion is will not differ by 5%

Answer:
Constants: The terms which are free from variables.
Numerical coefficient: Number multiplied with a variable.
(i) Constant = -3
Term which is not constant = 5x
Numerical coefficient = 5
(ii) 5x-3
Constant = 11
Term which is not constant
Numerical coefficient = -2
(iii) 11-2y squared
Constant = -1
Term which is not constant = 2x
Numerical coefficient = 2
Therefore, the terms which are not constants are 5x,-2y squared,2x respectively and their numerical coefficients are 5, -2, 2 respectively.
