Answer:
C) The sample does not accurately represent the population
N/13 = 15 with a remainder of 12:
Multiply both sides of this eq'n by 13, to eliminate fractions:
15N = 13(15) + 12 = 195 + 12 = 207
Let's check our answer.
Divide 13 into 207. Using a calculator, we find the quotient is 15.923.
The remainder is 0.923 times 13, or 12.
The number N is 207
Y = 0.75x - 6
If the line is parallel then the gradient is the same
Substitute in the values x = 4 and y = 5
5 = 0.75x4 +c
5 = 1 + c
c = 4
The equation of the line:
Y = 0.75x + 4
The angle measured is 1.72 radians
<em><u>Solution:</u></em>
Given that radius is 9 units and arc length is 15.5 units
To find: angle, 
, in radians
<em><u>The length of arc when angle in radians is given as:</u></em>
Where, "r" is the radius and "s" is the arc length
is central angle measured in radians
Substituting r = 9 and s = 15.5 in above formula,
Thus the angle measured is 1.72 radians
It would be - 77/4 because 9/14-11/14=- 1/7 then you do 11/4 -/ 1/7 which equals -77/4
