Your answer is 500, review the image I created to understand how I got my answer.
Step-by-step explanation:
I guess this means a reflection across the x-axis.
what does that mean ?
imagine the line of the x-axis is a mirror.
everything that is originally above the x-axis, is now below the x-axis.
and everything that is originally below the x-axis, is now above it.
as with an actual mirror, the closer something is originality to the mirror the closer it also appears to be in the mirrored image.
how do we do this in math ?
well, a functional value of e.g. 1 turns into -1.
e.g. 2 turns into -2.
but also e.g. -3 turns into 3.
in other words, we only need to flip the sign of the functional result values.
how do we do this ?
by multiplying the whole original functional value by -1.
and therefore,
g(x) = f(x) × -1 = (1/2 × x - 3) × -1 = -x/2 + 3
Using average x values and y values. The point is exactly halfway between the two points. Using midpoint formula is also helpful.
Answer:
Step-by-step explanation:
To be able to draw a conclusion from the data given, lets find out the p value using the t score and this will be used to make a conclusion.
If the p value is less than 0.05 then, we will reject the null but if otherwise we will fail to reject the null.
Using a p value calculator with a t score of 2.83, significance level 0.05 and the test is a two tailed test, the p value is 0.004655 which is less than 0.05 and the result is significant.
This we will reject the null hypothesis H0:p∗=1/2 for this data set.
