The measurement of the radius of the end of a log is found to be 9 inches, with a possible error of 1/2 inch. Use differentials
enot [183]

Answer:

\pm 9in^2

Step-by-step explanation:

We are given that

Radius of end of a log, r= 9 in

Error, \Delta r=\pm 1/2in

We have to find the error in computing the area of the end of the log by using differential.

Area of end of the log, A=pi r^2

\frac{dA}{dr}=2\pi r

\frac{dA}{dr}=2\pi (9)=18\pi in^2

Now,

Approximate error in area

dA=\frac{dA}{dr}(\Delta r)

Using the values

dA=18\pi (\pm 1/2)

\Delta A\approx dA=\pm 9in^2

Hence, the possible propagated error in computing the area of the end of the log=\pm 9in^2

What is the slope-intercept form of the function described by this table?
Mila [183]

Answer:

y=5x+3

Step-by-step explanation:

You have the points (1,8) (2,13) (3,18) (4,23)

first you want to find the slope.  The equation to find a slope is y2-y1 / x2-x1

your points (1,8) and (2,13) are really all you need

1 would be your x1 and your 2 would be your x2.

8 would be your y1 and 2 your y2

so you want to plug those into your equation y2-y1/x2-x1

13-8 /2-1 you get 5/1

Simplify your answer is 5 for your slope

Now finding the y intercept or "b" I normally just find the pattern of the sequence so in this case when you add one to the top your adding five to the bottom like

x  1   2  3   4

y  8 13 18 23

so to get to your y intercept which is (0,y)

subtract 1 from the top to get zero and subtract 5 from the bottom to get 3 so your y intercept is 3.

Hope this helps.

Or a population, N = 10,000, μ = 121, and σ = 21. Find to 2 decimal places the z value for
Ugo [173]

Answer:

The z value is - 2.88

Step-by-step explanation:

The formula of the z-score of a population is z = (x¯ - μ)/(σ/\sqrt{n})

The given in the problem is:

  • μ = 121
  • σ = 21
  • x¯ = 112.35
  • n = 49

Let us substitute all of these values in the rule above

z=\frac{112.35-121}{\frac{21}{\sqrt{49}}}

Simplify up and down

z=\frac{-8.65}{\frac{21}{7}}

z=\frac{-8.65}{3}

z = - 2.883333

Round it to 2 decimal places

∴ z = - 2.88

The z value is - 2.88
