Answer:
19.2cm²
Step-by-step explanation:
Given parameters:
Radius of the circle = 7cm
Angle subtended by the arc = 45°
Unknown:
Area of the sector = ?
Solution:
To find the area of the sector, use the expression below;
Area of sector =
where r is the radius ;
Insert the parameters and solve;
Area of sector =
x
x 7²
Area of sector = 19.2cm²
In normal distribution, 68% of the values are within +_ 1 SD. That leaves 32% outside that range. Thus, 32 people with greater than 13, 100 people greater than 14 (200*0.68/2+32)

Standard form is like
ax + by = c
4y - 3 = -5x
5x + 4y - 3 = 0
5x + 4y = 3 <----- answer
