A puddle is 0.06 feet deep after 1 hour and 0.03 feet deep after 5 hours. At what rate in

Fed [463]

Assuming it's a constant rate, there is a four hour difference from t=1 and t=5, so subtract the difference in depth (0.03 - 0.06) and divide that by four.

-0.03/4 = -0.0075
So your change in depth in feet per hour is -0.0075 $\frac{ft}{hr}$ .

Answer:

With a .95 probability, the margin of error is = 0.392

Step-by-step explanation:

Given -

In order to estimate the average time spent per student on the computer terminals at a local university, data were collected for a sample of 81 business students over a one-week period.

Sample size ( n ) =81

Standard deviation $(\sigma )$ = 1.8 hours

$\alpha$ = 1 -.95 =.05

$Z_{\frac{\alpha }{2}}$ = $Z_{\frac{.05 }{2}}$ = 1.96 (Using Z table)

With a .95 probability, the margin of error is

Margin of error = $Z_{\frac{\alpha }{2}}\frac{\sigma }{\sqrt{n}}$

= $Z_{\frac{.05 }{2}} \frac{1.8 }{\sqrt{81}}$

= $1.96\times 0.2$

Margin of error = 0.392

Solve the equation using square roots. Write your answer in simplest form.<br> Question in picture

GalinKa [24]

Answer:

The solutions to the quadratic equation involving square roots are:

$x=2\sqrt{7}i+8,\:x=-2\sqrt{7}i+8$

Step-by-step explanation:

Given the equation

$\frac{1}{4}\left(x-8\right)^2+8=1$

subtract 8 from both sides

$\frac{1}{4}\left(x-8\right)^2+8-8=1-8$

$\frac{1}{4}\left(x-8\right)^2=-7$

$\left(x-8\right)^2=-28$

$\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$
