melissa and brian are at the base of a moutain. melissa hikes to a location 27 meters above sea.level brian hikes to a location
sweet [91]

Answer:

The difference is 48 meters

Step-by-step explanation:

<u><em>The question is</em></u>

What is the difference of the hikers' altitudes?

Let

x -----> the Melissa's altitude in meters

y ----> Brian's altitude in meters

we have that

x=+27\ ft ---> is positive because is above sea level

y=-21\ ft ---> is negative because is below sea level

Remember that the sea level is the altitude equal to zero

<em>Find the difference</em>

To find out the difference of the hikers' altitudes, subtract Brian's altitude from Melissa's altitude

so

27-(-21)

Remember that (-1)(-1)=+1

27+21=48\ m

Ksivusya [100]

A) For this problem, we will need to use a normal calculation, in that we find the z-score and the area to the right using Table A.

z = (10 - 7.65) / 1.45

z = 1.62

area to the left for a z-score of 1.62 = 0.9474

area to the right for a z-score of 1.62 = 0.0526

The probability that a randomly selected ornament will cost more than $10 is 0.0526 or 5.26%.

B) For this problem, we will use the binomial probability formula since the problem is asking for the probability that exactly 3 ornaments cost over $10. There are two forms of this equation. One is <em>nCr x p^r x q^n-r</em> and the other is <em>(n r) x p^r x (1 - p)^n-r</em>. I will show both formulas below.

8C3 x 0.0526^3 x 0.9474^5

(8 3) x 0.0526^3 x 0.9474^5

With both equations, the answer is the same. Whichever you are more familiar or comfortable with is the one I would recommend you use.

The probability that exactly 3 of the 8 ornaments cost over $10 is 0.00622 or 0.622%.

Hope this helps!! :)
