During the grand opening of the T-Shirt Shack at the Madera County Emu Farm, four of the emus broke through the fence and attack

Irina-Kira [14]

Given :

p = 0.68

margin of error, E = 0.1

99% confident interval

alpha, α = 1 - 0.99

= 0.01

$\frac{\alpha }{2}=\frac{0.01}{2} = 0.005$

∴ $z_{\alpha/2}=z_{0.005}=2.5758$ (z-critical value)

Sample size = $z_{\alpha/2} \times \frac{p(1-p)}{E^2}$

$=(2.5758)^2 \times 0.68 \times \frac{(1-0.68)}{0.1^2}$

$= 6.63475 \times 0.68 \times \frac{0.32}{0.01}$

= 144.37

= 145 (rounded off)

Therefore, there are 145 businesses does she need to sample to meet this criteria.

A shape is made of 12 right triangle of equal size. Each righ triangle has a base of 4 cm and a height of 5 cm. What is the tota

ioda

Answer: 120 cm².

Step-by-step explanation:

1. To solve this problem you must apply the formula for calculate the area of a triangle, which is:

$A=\frac{b*h}{2}$

Where b is the base and h is the height of the triangle.

2. Then, when you substitute the values given in the problem you obtain:

$A=\frac{(4cm)(5cm)}{2}=10cm^{2}$

3. You know that the shape is made of 12 right triangle of equal size, therefore, multiply the area obtained by 12.

4. Then the area of the shape is:

$A_s=12(10cm^{2})=120cm^{2}$
