Answer:
Step-by-step explanation:
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!! :)
Answer:
No because the <em><u>x</u></em><em><u> </u></em><em><u>value</u></em><em><u> </u></em><em><u>does</u></em><em><u> </u></em><em><u>not</u></em><em><u> </u></em><em><u>change</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>1</u></em><em><u> </u></em><em><u>everytime</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>y</u></em><em><u> </u></em><em><u>value</u></em><em><u> </u></em><em><u>changes</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>5</u></em>
Step-by-step explanation:
Rate of Change = Slope
If the slope was 5, the the point on the graph would be on the coordinate (1,5)
<em>However</em><em>,</em><em> </em>the graph provided does NOT show 5 as being the slope because the line does not go through 0 and the <em><u>x value does not change by 1 everytime y changes by 5.</u></em>
If it did, however, it would look something like this picture.
Answer:
8+4pi
Step-by-step explanation:
2pi(r) = 8pi
8pi/2 = 4pi
