AP Statistics
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!! :)

What’s the answer to this
KonstantinChe [14]

Answer:

C

Step-by-step explanation:

  • (a+b)² = a² + 2ab  + b²
  • example : (5+2)² = 5² + 2.5.2 + 2²  = 49

9x² + 6x + 1

9x²  = (3x)²

1 = 1²

6x = 2.3x.1

So => 9x² + 6x + 1 => <em>(3x + 1)² </em>

Hope this helps ^-^

The cost to a rent paddle boat at the county park is $8 per hour if x represent the number off hours the boat is rented and for
bazaltina [42]

Answer:

10+8x=y

Step-by-step explanation:

The 10$ is added on because it's a one time exchange and the 8 is multiplied by the x because for every hour you add 8$ to the price and y is the total price at the end depending on x.
