Answer:
I also found all of the answers for that package
Step-by-step explanation:
Is there an image so I can see
P(<em>Z</em> ≥ <em>z</em>) = 1 - P(<em>Z</em> ≤ <em>z</em>) = 0.06
==> P(<em>Z</em> ≤ <em>z</em>) = 0.94
==> <em>z</em> ≈ 1.7507
Answer:
area of the rectangle =length *breadth
=14*5=70sq.ft
diameter =6ft
radius =3ft
area of the semi circle =1/2πr^2
=1/2*22/7*3*3=14.142sq.ft
area of the figure =area of the rectangle +area of the semi circle =70+14.142=84.142sq.ft
Answer:
D: Undefined
Step-by-step explanation:
You can use the unit circle or your calc for this (don't forget to put it in radians!). I will use the unit circle to explain.
Tangent on the unit circle is on the xy lines themselves. tan (π/2) would be on the positive y axis. Remember that tan∅ is <em>sin∅/cos∅</em> and that the unit circle's radius is always one. If that is the case, the coordinate for tan (π/2) would be (0, 1). If cos is always x and sin is always y, you plug it in for tan∅. The fraction 1/0 is undefined, since you can't divide anything by 0. Therefore, tan (π/2) is undefined.
