Answer:

Copy's area is 16 times bigger then triangle area.

Step-by-step explanation:

Given:

Area of copy = 72 unit²

Find:

How bigger copy compared to triangle

Computation:

Area of triangle = [1/2][base][height]

Area of triangle = [1/2][3][3]

Area of triangle = 4.5 unit²

So.

Area of copy / Area of triangle

72 / 4.5

16

So,

Copy's area is 16 times bigger then triangle area.

Construct an equation that has n = 6 as its solution. Use n on both sides of the equation.
nevsk [136]

Answer:

See Explanation

Step-by-step explanation:

Required

Determine any equation where n = 6

n = 6

Add n to both sides

n + n = 6 + n

<em></em>2n = 6 + n<em> ----- This is 1 equation</em>

n = 6

Multiply both sides by n

n * n = 6 * n

<em></em>n^2 = 6n<em> ----- This is another</em>

<em></em>

n = 6

Add 5n to both sides

n + 5n = 6 + 5n

<em></em>6n = 6 + 5n<em> ---- This is another</em>

Subtract 10 from both sides

6n - 10 = 6 - 10 + 5n

6n - 10 = -4 + 5n

<em></em>6n - 10 = 5n - 4<em> --- This is another</em>

<em>You can have as many equations as possible</em>

Find the sample size required to achieve the given margin of error with SD = 51.02 and z - score = 1.96. Round your answer to th
coldgirl [10]

Answer:

The sample size required is 2500.

Step-by-step explanation:

z-score:

In function of the margin of error M, the z-score is given by:

Z = \frac{M}{\frac{\sigma}{\sqrt{n}}} = \frac{M\sqrt{n}}{\sigma}

In this question, we have that:

\sigma = 51.02, M = 2, Z = 1.96

So

Z = \frac{M\sqrt{n}}{\sigma}

1.96 = \frac{2\sqrt{n}}{51.02}

2\sqrt{n} = 51.02*1.96

\sqrt{n} = \frac{51.02*1.96}{2}

(\sqrt{n})^2 = (\frac{51.02*1.96}{2})^2

n = 2500

The sample size required is 2500.
