Vertex of f(x)=x^2-x+2 is:
(0.5,1.75)
Answer:
The answer to your question is: 45° and 225°
Step-by-step explanation:
Getting tan⁻¹ 1 = 45°
Then, the angle we are looking for is 45°, let's check the for quadrangles.
First quadrangle = tan 45 = 1
Second quadrangle = 180° - 45° = 135° tan 135 = -1
Third quadrangle = 180 + 45 = 225° tan 225 = 1
Forth quadrangle = 360 - 45 = 315° tan 315° = -1
Answer:
Step-by-step explanation:
First change 4 3/10 to 4.3. Then you change 4.3 + -6.2 to 4.3 - 6.2.
Then you do 4.3 - 6.2 and you should get - 1.9.

Answer:
0.29
Step-by-step explanation:
Given :
n : ___ 0 _____ 1 ____ 2 ____ 3 ____ 4
P(n) : 0.82___ 0.11 ___0.04 _0.02 ___0.01
The expected number of defect in a shipment can be obtained using the expected value formula :
Expected value, E(X) = Σx*p(x)
Σx*p(x) = (0*0.82) + (1*0.11) + (2*0.04) + (3*0.02) + (4*0.01)
E(X) = 0.29
Hence, the expected number of defect in shipment is 0.29
