5. Part A: Show another way to find the slope of the line that passes through the points listed in the table. Your way must be d

ifferent from Avery's method.
. Part B: Justify why Avery's "divide y by x" method will not work to find the slope of every line and given an example (using a table, equation, or graph) in your justification

Answer:

<u>The slope-intercept form </u>

  • y = mx + b

Here m is the slope and b is y-intercept

<u>When b= 0</u>

  • y = mx

and

  • m = y/x

In this case Avery's method works

<u>When b≠0</u>

  • m = (y -b)/x

In this case Avery's method brings wrong outcome

Find the surface area of the right square pyramid. Round your answer to the nearest hundredth.
Mademuasel [1]

ANSWER

C. 145.75 yd²

EXPLANATION

First we need to calculate the area of the four triangular faces.

The lateral surface area

= 4 \times  \frac{1}{2}  \times 5.3 \times 11.1

= 117.66 {yd}^{2}

The area of the base is

= 5.3 \times 5.3

= 28.09

To find the total surface area, we add the area of the square base to the area of the 4 triangular faces.

Therefore the total surface area is

= 117.66 + 8.09 = 145.75 {yd}^{2}

Matthew plays basketball for his high school. On average, he scores 33 points per game, with a standard deviation of 2 points. W
Lera25 [3.4K]
<h3>Answer: Choice B</h3>

Matthew will score less than 27 points in about 0.15% of his basketball games.

=======================================================

Explanation:

mu = 33 = population mean

sigma = 2 = population standard deviation

Let's find the z score when x = 27

z = (x - mu)/sigma

z = (27-33)/2

z = -6/2

z = -3

A score of 27 points is exactly three standard deviation units below the mean of 33 points.

Now refer to the Empirical Rule chart shown below. Notice that roughly 99.7% of the entire population is within 3 standard deviations of the mean. This is the span from z = -3 to z = 3.

That leaves about 100% - 99.7% = 0.3% left over for the two tails combined.

One tail has about (0.3%)/2 = 0.15% of the total area, and therefor about 0.15% of the total games will have Matthew scoring less than 27 points. This is an estimate of course.

To get a more accurate answer, you can use a Z table to find that

P(Z < -3) \approx 0.00135 \approx 0.135\%

which isn't too far off from the 0.15%
