Answer:
7,9
Step-by-step explanation:
Let two consecutive odd integer=X and (X+1)
The difference of the squares of two positive consecutive odd integers is 32.
So(X+2)^2-x^2=32
(x^2+4+4x)-x^2=32
x^2+4+4x-x^2=32
4x=32-4
4x=28
X=28/4
X=7
So first integer=7
Second integer=7+2
=9.

Complete Question
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]

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

What is the percent of increase from 6 to 9? Write your answer using a percent sign (%)
Answer:
The percent of increase from 6 to 9 is 50%
Step-by-step explanation:
Percentages
To calculate the percentage increase:
Work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Divide the increase by the original number and multiply the answer by 100.
We are required to find the percent increase from 6 to 9. Here: New number=9, Original number = 6
Increase = 9 - 6 = 3
Divide 3 by 6 and multiply the answer by 100:
3 / 6 * 100 = 50%
The percent of increase from 6 to 9 is 50%
The percent of increase from the number 6 to 9 is 50 percent.
The given numbers are 6 and 9.
Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
The difference of the given numbers
= 9-6
= 3
The percent of increase = 3/6 ×100
= 0.5×100
= 50%
Therefore, the percent of increase from the number 6 to 9 is 50 percent.

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 _____.
a. there is no correlation between x and y
b. there is a negative correlation between x and y
c. there is a positive correlation between x and y
d. the y-intercept is 0
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.
