Answer:
The answer to your question is 7:6
Step-by-step explanation:
Data
Number of red marbles = 28
Number of green marbles = 30
Number of yellow marbles = 24
Radio = ?
Process
1.- Write the ratio
Red marbles : Yellow marbles
2.- Substitution
28 : 24
3.- Simplification
-Divide both terms by 2
14 : 12
-Divide by two both terms
7 : 6
-It is not possible to simplify more.
Combine like terms
-2x-4=-2x-4
Since the equations are the same, the answer is infinitely many solutions.
Answer:
Modification has not reduced the number of accidents.
Step-by-step explanation:
A B C D E F G H
Before modification 5 7 6 4 8 9 8 10
After modification 3 7 7 0 4 6 8 2
Difference -2 0 1 -4 -4 -3 0 -8
Mean of differences 
Standard deviation of differences = 
Formula of paired t test :
Df = n-1 = 8-1 =7
t critical> t calculated
So, We failed to reject null hypothesis
Hence modification has not reduced the number of accidents.
Answer:
y=2x+35
Step-by-step explanation:
so y is what it's equal too so you put y=
then since its $2 every mile you put them next to eachother like
2x so y=2x
then there is just a plain fee of $35 so you add that to the equation which is what makes it look like
y=2x+35
Hope this helps!! :D
