<span>y=-2/4x +2
slope = -2/4 = -1/4
</span><span>parallel so it has same slope = -1/2
passing thru (6,3)
y = mx+b
3 = -1/2(6) + b
b = 3 +3
b = 6
equation
y = -1/2x + 6</span>
Answer:
Domain x ∈ R
Range y ∈ R
Step-by-step explanation:
Since the radical function have its exponential odd, there are no restrictions in what result should have in order to not obtain a complex value, that is why the domain is every real number (x ∈ R)
Now, to obtain the range, we have to determine possible values for 'y' variable. Since there are no restrictions in domain, and the function y=
doesnt have limits, we can say that y also belongs to all real domain.
The number of standard deviations from the mean for a man 72 inches tall is
Z = (72 -69.3)/2.8 ≈ 0.964
You would just subtract/add like you normally would from left to right because its a subtract and add operation.
Hope that helps :)
