Answer:

The margin of error is given below:

$E=z \times \sqrt{\frac{\hat{p}(1-\hat{p}}{n} }$

Where:

$\hat{p}=\frac{26}{80}=0.325$

$\therefore E = z \times \sqrt{\frac{0.325(1-0.325}{80} }$

$=z \times 0.0523659$

Therefore, the option E = z*6% is correct as it closest to the given answer

Answer:

1.5 units squared

Step-by-step explanation:

Area of a Triangle formula: A = 1/2bh

Pythagorean Theorem: a² + b² = c²

Since you are missing the <em>h </em>to find the area of the triangle, you must use Pythagorean to find the 3rd missing side (it is a right triangle so you can use Pythagorean).

Step 1: Use Pythagorean

2.5² = 1.5² + b²

4 = b²

b = 2

Step 2: Switch variables

b (from Pythagorean) = h (height for Area)

Step 3: Solve for Area

A = 1/2(1.5)(2)

A = 1.5

And you have your final answer.

A rectangle has a height of 3 cm and width of 5cm. A proportional rectangle has a height of 12cm. What would be the width?

Schach [20]

The ratio will be same

Let width be x

$\\ \sf\longmapsto \dfrac{3}{5}=\dfrac{12}{x}$

$\\ \sf\longmapsto 3x=5(12)$

$\\ \sf\longmapsto 3x=60$

$\\ \sf\longmapsto x=\dfrac{60}{3}$

$\\ \sf\longmapsto x=20cm$
