Find the measure of the line segment GE. Assume that lines which appear tangent are tangent.

Answer:

The measure of the line segment GE is 18\ units

Step-by-step explanation:

we know that

<u>The Intersecting Secant-Tangent Theorem</u> , states that the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment

so

In this problem

GE*GF=GH^{2}

substitute the values

(8+x)(8)=12^{2}

solve for x

8x+64=144

8x=144-64

8x=80

x=10

Find the measure of the line segment GE

GE=8+10=18\ units

yanalaym [24]
We know there’s 660 boxes and each box called for 3 eggs, therefore:

660=3X

when divide both sides by 3 to isolate the x, which will tell us the amount of eggs used…

660/3 = 220

Using the normal distribution, it is found that there is a 0.1357 = 13.57% probability that the total  amount paid for these second movies will exceed $15.00.

In a <em>normal distribution</em> with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

  • It measures how many standard deviations the measure is from the mean.  
  • After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
  • For n instances of a normal variable, the mean is n\mu and the standard error is s = \sigma\sqrt{n}

In this problem:

  • Mean of $0.47, standard deviation $0.15, hence \mu = 0.47, \sigma = 0.15
  • 30 instances, hence n\mu = 30(0.47) = 14.1, s = 0.15\sqrt{30} = 0.8216

The probability is <u>1 subtracted by the p-value of Z when X = 15</u>, hence:

Z = \frac{X - \mu}{\sigma}

Considering the n instances:

Z = \frac{X - n\mu}{s}

Z = \frac{15 - 14.1}{0.8216}

Z = 1.1

Z = 1.1 has a p-value of 0.8643.

1 - 0.8643 = 0.1357.

0.1357 = 13.57% probability that the total  amount paid for these second movies will exceed $15.00.
