The volume of the Aquarium using the following:
V = lwh
V = 12(18)(10)
V = 2160 in³

We need to divide this by 231 to get the number of gallons necessary.
2160/231 ≈ 9.35 gallons of water.

So NO! 9.35 gallons of water needed

Many people who bought Z-Game gaming systems over the holidays have complained that the systems they purchased were defective. I

Answer:

The upper limit for the 95% confidence interval for the population proportion of defective gaming systems is 0.022

Step-by-step explanation:

Upper Limit for 95% Confidence Interval can be calculated using p+ME where

p is the sample proportion of defective gaming systems ( $\frac{18}{1200} = 0.015$ )

ME is the margin of error from the mean

and margin of error (ME) around the mean can be found using the formula

ME= $\frac{z*\sqrt{p*(1-p)}}{\sqrt{N} }$ where

z is the statistic of 95% confidence level (1.96)

p is the sample proportion ( $\frac{18}{1200}=0.015$

N is the sample size (1200)

Using the numbers we get:

ME= $\frac{1.96*\sqrt{0.015*0.985}}{\sqrt{1200} }$ ≈ 0.007

Then upper limit for the population proportion is 0.015+0.007 =0.022

Given g(x)=Squareroot x-4 and h(x)=2x-8, what are the restriction on the domain of gofh?

jolli1 [7]

The square root has to be >= to zero, so g(h(x)) = SQRT((2x-8)-4)
where 2x-12>=0 or x>=6
