To estimate the height of a totem pole, Jorge uses a small square of plastic. He holds the square up to his eyes and walks backw

ard from the pole. He stops when the bottom of the pole lines up with the bottom edge of the square and the top of the pole lines up with the top edge of the square. Jorge's eye level is about 2 m from the ground. He is about 3 m from the pole. Which of the following is the best estimate of the height of the totem pole?

The height of the pole is 6.50 meters

<h3>How to calculate the height?</h3>

To calculate the height of the pole, we will use of the following equivalent ratios.

By Pythagoras theorem, we have:

x ^2 = 2^2 + 3^2\\\\x ^2 = 4 + 9\\\\x = \sqrt{13}

So, we have:

h = \dfrac{\sqrt{13}^2 }{2} \\\\h = \dfrac{13}{2}\\\\h = 6.5

Hence, the height of the pole is 6.50 meters

Solve for x. <br><br><br> 7x/2+5=8
finlep [7]

Answer:

x=6/7

Step-by-step explanation:

7x÷2+5=8

divide by 2 on both sides:

7x/2+5=8(it's a fraction)

subtract 5 on both sides

7x÷2=3

multiply 2 on both sides

7x=6

divide by seven on both sides

x=6/7

hope this was helpful and the instructions were clear enough!

Suppose that a stock is currently selling for $100. The change in the stock's price during the next year follows a normal random
Basile [38]

Answer:

The probability that the stock will sell for $85 or less in a year's time is 0.10.

Step-by-step explanation:

Let <em>X</em> = stock's price during the next year.

The random variable <em>X</em> follows a normal distribution with mean, <em>μ</em> = $100 + $10 = $110 and standard deviation, <em>σ</em> = $20.

To compute the probability of a normally distributed random variable we first need to compute the <em>z</em>-score for the given value of the random variable.

The formula to compute the <em>z</em>-score is:

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

Compute the probability that the stock will sell for $85 or less in a year's time as follows:

Apply continuity correction:

P (X ≤ 85) = P (X < 85 - 0.50)

                = P (X < 84.50)

                =P(\frac{X-mu}{\sigma}

                =P(Z

*Use a <em>z</em>-table for the probability.

Thus, the probability that the stock will sell for $85 or less in a year's time is 0.10.
