Q: The table shows the weights of apples at a grocery store. If this represents a proportional relationship, what is the weight of 12 apples? Remember to explain your answer :)
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)
hope this helps :)
b) (-4,-2) and (-3,5)
slope intercept form solve for b
Answer:
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

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.

A measurement template with a historcal value of 25.500 is measured 27 times and a mean value of 25.301 is recorded. What is the percent bias when the tolerence is -0.3?
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]
