Answer:
mean age of women
(x+y+z)/3=27
mean age of men
(x1+x2+x3+x4+x5+x6)/6=34
mean age of all people in the office
x+y+z=27*3=81
x1+...x6=34*6=204
so
mean age( x+y+z+x1+x2+..x6)/(3+6)=(27*3+34*6)/9
=(81+204)/9=285/9=32 approximately
Answer:
The perimeter would be 8 (units)
Step-by-step explanation:
To find perimeter you just add up all the sides. If your sides are 2 and 2 then the opposite L and W sides should be the same making the total perimeter 8.
The exact value of cos120 if the measure 120 degrees intersects the unit circle at point (-1/2,√3/2) is 0.5
<h3>Solving trigonometry identity</h3>
If an angle of measure 120 degrees intersects the unit circle at point (-1/2,√3/2), the measure of cos(120) can be expressed as;
Cos120 = cos(90 + 30)
Using the cosine rule of addition
cos(90 + 30) = cos90cos30 - sin90sin30
cos(90 + 30) = 0(√3/2) - 1(0.5)
cos(90 + 30) = 0 - 0.5
cos(90 + 30) = 0.5
Hence the exact value of cos120 if the measure 120 degrees intersects the unit circle at point (-1/2,√3/2) is 0.5
