Answer:
Do you have an equation to find the answer?
Answer:
C) 0.45
Step-by-step explanation:
Given that a population mean is 0.45, standard deviation is 0.001 and margin of error stands at 0.5% we have the following
0.45 + 0.001 = 0.451
Population mean with standard deviation is 0.451.
0.451 * 0.5% = 0.448745
We now reduce the number to two decimals and get the final marigin of error
0.45 as result
2.5 belongs woth numbers under 10 and decimals
Hello!
We can put in numbers for x to get points of the graph
2(-4)^2 + 16(-4) + 30 = -2
One point is (-4, -2)
2(-3)^2 + 16(-3) + 30 = 0
The next point is (-3, 0)
2(-5)^2 + 16(-5) + 30 = 0
The third point is (-5, 0)
The parabola has a vertex of (-4, -2) and goes through the points (-3, 0) and (-5, 0)
Hope this helps!
