Answer:
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
Step-by-step explanation:
Radius = 15 feet
circumference = 2 * PI * 15 =

94.25 </span></span></span>feet
the length of the arc is 10 feet
So the angle would equal (10 / 94.25) * 360 =

* 360 =

9) x.14 = 6.26 ==> 14x=156 ==> x=11.1
12) OAB = Right Triangle : (27+24)² = 24² + AB² (Pythagoras)
==> 51² =24² + AB² ==> 2,601 = 576 + AB² ==> AB² = 2,601 - 576 = 2,025
==> AB² = 2015 AND AB =√2025 = 45
Sorry I can't read the last page
26 to nearest year
We require the total of the sums of ages for both groups before calculating the mean for all 16
using mean = 
Women
27 = 
( cross- multiply )
sum = 9 × 27 = 243
Men
25 = 
( cross- multiply )
sum = 7 × 25 = 175
Total sum of all 16 = 243 + 175 = 418
mean = 
= 26 ( to nearest year )
The answer is 6/15. Hope this helped!
