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.

8/5 ( 2x + 13 ) - 3 = 22

Alona [7]

Answer:

$x = \frac{21}{16}$ = 1 5/16

[/tex] 1 \frac{5}{16}[/tex]

Step-by-step explanation:

$\frac{8}{5} (2x + 13) - 3 = 22$

Expand

$\frac{16}{5} x + \frac{104}{5} - 3 = 22 \\ \frac{16}{5} x + \frac{89}{5} = 2$

Collect like terms and simplify

$\frac{16}{5} x = 22 - \frac{89}{5} \\ \frac{16}{5} x = \frac{21}{5}$

Cross Multiply

$80x = 105$

Divide both sides of the equation by 80

$\frac{80x}{80} = \frac{105}{80} \\ x = \frac{21}{16}$
