Answer:
The probability that the mean of the sample would differ from the population mean by less than 36 points=0.9216
Step-by-step explanation:
We are given that
The variance of the scores on a skill evaluation test=143,641
Mean=1517 points
n=343
We have to find the probability that the mean of the sample would differ from the population mean by less than 36 points.
Standard deviation,




Hence, the probability that the mean of the sample would differ from the population mean by less than 36 points=0.9216
First, rearrange the quadratic equation:
5x² + 9x - 4 = 0
Now, compare it to the general quadratic equation:
a<span>x² + bx + c = 0
Therefore you get:
a = +5
b = +9
c = -4
And the quadratic formula will be:
x = [-b +/- </span>√(b² - 4ac)] / 2a
= [ -5 +/- √(81 - 4·5·(-4))] / 2·5
= (-5 +/- √161) / 10
Check the picture below.
as you recall from the previous exercise, x = 74°, now, using the "inscribed angle theorem" as you saw already, the green intercepted arc is 160°, so y = 160° - 74°.
as far as ∡z, well, we can just use the "inscribed quadrilateral conjecture".
