Answer:
y = x2 - 4x + 2 ; y=x²-4
Step-by-step explanation:
Axis of symmetry = - b /2a
y=x²-2
a = 1 ; b = - 2
x = - (-2) / 2(1)
x = 2/2 = 1
y = x2 - 4x + 2
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
y = x2 + 4x + 2
a = 1 ; b = 4
x = - 4 / 2(1)
x = - 4/2 = - 2
y=x²-4
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
Answer:
(a) 1/2
Step-by-step explanation:
The coordinates of the point of intersection of the terminal side of angle α with the unit circle are ...
(x, y) = (cos(α), sin(α))
When α = 60°, the x-coordinate of the terminal point is cos(60°) = 1/2.
Answer:
The null hypothesis, H₀ is that the mean completion time for the TPS report remains at the duration of 6.3 hours
The alternative hypothesis, H₁ is that the mean completion time for the TPS report is less than 6.3 hours
Step-by-step explanation:
The given parameters are;
The average time spent on the TPS report = 6.3 hours
The number of workers in the sample used for the test = 48 office workers
The mean completion time of the TPS report for the sample = 5.7 hours
The test aim; To find out whether the mean time required to fill out the TPS report has been reduced
The null hypothesis, is H₀; μ = 6.3 hours
The alternative hypothesis, H₁; μ < 6.3 hours
