Answer:
Step-by-step explanation:
1. Begin by graphing the y-intercept of +1. The y-intercept exists where x = 0; therefore, the coordinate of the y-intercept is (0, 1). Plot this point.
2. From the y-intercept, incorporate the slope by going up or down then right or left. The slope is 2, which can be written as +2/+1; this means from the y-intercept you will move up 2 units and then over to the right 1 unit and make another point.
3. Connect the 2 points to make your line.
Maybe you're confused by this number e.
Replace e with the number 2 and rethink your options:
x^2
2^x
2x
So you think maybe it's C.
2x represents a straight line, ya?
Straight line is going to grow much slower than x^2, a parabola, ya?
But both of those will grow much much slower than an exponential function 2^x.
Oh oh I misread the question.. they wanted the SLOWEST growth, not the fastest. Yes you have the correct option! :)
The margin of error is 0.97849
we are given
mean=235
so,
standard deviation =7.5
so,
we know that
ME=2*standard error
and
If confidence level is 95%, then we can multiply by 1.96
so, we can multiply by 2 to get ME
now, we can use marginal error formula
now, we can plug values
and we get
