An article in the ASCE Journal of Energy Engineering ("Overview of Reservoir Release Improvements at 20 TVA Dams," Vol. 125, April 1999, pp. 1-17) presents data on dissolved oxygen concentration from streams below 20 dams in the Tennessee Valley Authority system. The sample mean from the observations equals 3.234 and the sample standard deviation is s = 2.121. a) Calculate the 95% two-sided prediction interval on the dissolved oxygen concentration for the next stream that will be tested. (rounded to two decimal places)

Answers

Answer:

95% confidence interval: (2.241,4.227)

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = 3.234

Sample size, n = 20

Alpha, α = 0.05

Sample standard deviation, σ = 2.121

95% confidence interval:

$\bar{x} \pm t_(critical)\displaystyle(s)/(√(n))$

Putting the values, we get,

$t_(critical)\text{ at degree of freedom 19 and}~\alpha_(0.05) = \pm 2.093$

$3.234 \pm 2.093((2.121)/(√(20)) ) = 3.234 \pm 0.993 = (2.241,4.227)$

(2.241, 4.227) is the required confidence interval.

Solve for x x-23=17 NEED TO KNOW FAST PLEASE!!!!

Answers

Answer:

x = 40

Step-by-step explanation:

Adding 23 to both sides gives us:

x - 23 + 23 = 17 + 23

x = 40

Answer:

$\boxed{ \bold{ \bold{ \sf{x = 40}}}}$

Step-by-step explanation:

$\sf{x - 23 = 17}$

Move constant to right hand side and change it's sign

$\sf{x = 17 + 23}$

Add the numbers

$\sf{x = 40}$

Hope I helped!

Answer with Step-by-step explanation:

Given

$f(x)=(1-cos(2x))/(1-cos(x))\n\n\lim_(x \rightarrow 0)f(x)=\lim_(x\rightarrow 0)(\frac{1-(cos^2{x}-sin^2{x})}{1-cos(x)})\n\n(\because cos(2x)=cos^2x-sin^2x)\n\n\lim_(x \rightarrow 0)f(x)=\lim_(x\rightarrow 0)((1-cos^2x)/(1-cos(x))+(sin^2x)/(1-cosx))\n\n=\lim_(x\rightarrow 0)(((1-cosx)(1+cosx))/(1-cosx)+(sin^2x)/(1-cosx))\n\n=\lim_(x\rightarrow 0)((1+cosx)+(sin^2x)/(1-cosx))\n\n\therefore \lim_(x \rightarrow 0)f(x)=1$

Toy company produces rubber balls that have a radius of 1.7 cm.A sphere has a radius of 1.7 centimeters.
What is the volume of one rubber ball? Round to the nearest hundredth of a centimeter.

Answers

Answer:

The volume of one rubber ball is 20.58 cubic centimeters.

Step-by-step explanation:

The rubber ball has a spheric format.

A sphere with radius r has volume given by the following equation:

$V = (4\pi r^(3))/(3)$

In this question:

r = 1.7 cm.

The radius is in centimeters, so the volume will be in cubic centimeters.

What is the volume of one rubber ball?

$V = (4*\pi*(1.7)^(3))/(3) = 20.58$

The volume of one rubber ball is 20.58 cubic centimeters.

Answer:

1) 20.58 cm

2) $0.09

3) $0.41
