Answer:
x=55
Step-by-step explanation:
The exterior angles of a polygon add to 360.
x+x+x+x+x+x+30 = 360
Combine like terms
6x+30 = 360
Subtract 30 from each side
6x+30-30 = 360-30
6x = 330
Divide by 6
6x/6 =330/6
x =55
Answer:
1727 students
Step-by-step explanation:
Here we have the formula for sample size given as

Where:
p = Mean
ME = Margin of error = 3
z = z score
Therefore, we have
p = 150/240 = 0.625
z at 99 % = 2.575
ME =
3%
Therefore 
The number of students Professor York have to sample to estimate the proportion of all Oxnard University students who watch more than 10 hours of television each week within ±3 percent with 99 percent confidence = 1727 students.
The amount of Federal Taxes that Curtis pays annually would be 1538.68.
Answer:44
Step-by-step explanation: 60/5 evaluates to 12
Multiply 3 and 12
1
3*(60/5) evaluates to 36
8+3*(60/5) evaluates to 44
Answer:
Point slope formula: (y + 4) = 2(x - 5)
Slope intercept formula: y = 2x - 14
Step-by-step explanation:
Point slope formula: (y + 4) = 2(x - 5)
Slope intercept formula: y = 2x + b, -4 = 10 + b, b = -14
y = 2x - 14
