A measurement template with a historical value of 25.500 mm is measured 27 times and a mean value of 25.301 mm is recorded. What is the percent bias when the tolerance is +/- 0.3?

Answer:

The percent bias is  [tex]B = 33.167 \%[/tex]  

Step-by-step explanation:

From the question we are told that

   The historical value  is  [tex]S = 25.00 \ mm[/tex]

   The number of times it is measured is  n  =  7  

    The mean value is  [tex]\= x = \frac{\sum x_i }{n} = 25.301 \ mm[/tex]

    The tolerance is  [tex]t =\pm 0.3 = 0.3 - (-0.3) = 0.6[/tex]

Generally the percent bias is mathematically represented as

      [tex]B = 100 * \frac{\= x - \tau }{ t}[/tex]

=>  [tex]B = 100 * \frac{25.301 - 25.5000 }{0.6}[/tex]

=>  [tex]B = 33.167 \%[/tex]

ANSWER

[tex] 18\pi\: cm^3/s[/tex]

STEP-BY-STEP EXPLANATION:

[tex] V= \frac {4}{3}\pi r^3\\\\

[/tex]

Differentiating with respect to t on both sides:

[tex] \frac{dV}{dt} = \frac {4}{3}\pi\times 3r^2\frac{dr}{dt} \\\\

\frac{dV}{dt} =4\pi r^2\frac{dr}{dt} .. (1)\\\\

Plug \:\frac{dr}{dt} = \frac{1}{2}\:\: \& \: \: r = 3\: in \: equation \: (1)\\\\

\frac{dV}{dt} =4\pi (3)^2\times \frac{1}{2}\\\\

\frac{dV}{dt} =4\pi\times 9\times \frac{1}{2}\\\\

\huge \purple {\boxed{\frac{dV}{dt} =18\pi\: cm^3/s}} \\[/tex]

Step 1: So to start us off, because every 5 apples weighs 0.60 kilograms, we're going to divide 0.60 by 5 to get the weight of ONE apple.

0.60 divided by 5= 0.12

Now we know how much a single apple weighs in kilograms and we can move onto the next step.

Step 2: The next step is to times the weight of one apple by 12 because that would give us our answer for the weight in kilograms of 12 apples.

0.12 times 12=1.44

Hopefully, this is correct and helps you! Sorry if I made any errors, it would be best to go back and do the steps yourself just to make sure if that makes you feel any better. Good luck! xxoo

Answer:

1.44kg

Step-by-step explanation:

If they are proportional then you can use the unitary method:

If 5 apples=0.6kg then 1 apple=0.12kg as this is 0.6/5 (because you divided the apples by 5 so you have to do the same to the kg)

then you can work out that 12 apples=1.44kg because 0.12*12 is 1.44 and you multiply by 12 as this is what you multiplied the apples by so (becasue they are proportional then you have to do the same to the kg)

Answer:

c. there is a positive correlation in-between x and y

Step-by-step explanation:

A regression line is a line that suggests that all the points in a scatter diagram lie on or near one particular line. In a simple regression analysis in which y is the dependent variable and x is the independent variable. If the slope is positive, the bivariate data is also said to have a positive correlation. The positive correlation in-between two variables x and y implies that in general, an increase in x goes hand in hand with an increase in y.

Regression Analysis is defined as the set of statistical and reliable processes for establishing the relationship between the independent and dependent variables.

The correct statement can be given as:

In a simple regression analysis (where y is a dependent and x an independent variable), if the slope is positive, then it must be true that there is a positive correlation between x and y.

The regression line suggests that all the points lie near a particular line. It can be explained as:

1. In a simple regression analysis, the dependent variable is y.

2. Similarly, the independent variable is x.

3. Given, if the slope is positive, then the correlation will be positive.

4. The positive relation implies that if x increases then they will also increase in simple regression analysis.

Thus, in the simple regression analysis there exists a positive correlation between x and y.

When a fraction equals zero :

6.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 -v-59

 ————— • 9 = 0 • 9

   9  

Now, on the left hand side, the  9  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -v-59  = 0

Solving a Single Variable Equation:

6.2      Solve  :    -v-59 = 0

Add  59  to both sides of the equation :

                     -v = 59

Multiply both sides of the equation by (-1) :  v = -59

b= 26

Step-by-step explanation:

First, find the slope using the slope formula,

[tex]m=\frac{5-\left(-2\right)}{-3-\left(-4\right)}[/tex]       solve and simplify, m=7

plug in one pair of coordinates for the y and x for the slope intercept form,

(I'll just use (-3,5))

y=mx+b

5=7(-3)+b

5=-21+b

5+21=21-21+b

b=26                       After solving the problem, b=26
