Lets say W=Wesley, M=Max, and J=Jared.
So your equations are M=2J, 2M=W, and M+J+W=21days(3 weeks)
So substituting M and W into M+J+W=21 gives you 2J+J+2M=21, substitute M again, to get 2J+J+4J=21 so you get 7J=21 so J= 3 days. Using J=3, substitute in to find M, using M=2J, so M=2(3) so M=6 and using that, substitute into 2M=W, so 2(6)=W so W=12. And 12+6+3=21 to check.
Step-by-step explanation:
392 miles because when she was walking for two hours then she want to go home because her home was only take 6 hours she didn't want to spend her time
The answer is no real solution
Step-by-step explanation:
Let's solve your equation step-by-step.
3x2=−12x−15
Step 1: Subtract -12x-15 from both sides.
3x2−(−12x−15)=−12x−15−(−12x−15)
3x2+12x+15=0
Step 2: Use quadratic formula with a=3, b=12, c=15.
x=
−b±√b2−4ac
2a
x=
−(12)±√(12)2−4(3)(15)
2(3)
x=
−12±√−36

Answer:
The correct answer is the scatter plot which has a strong positive slope of the curve of best fit.
Step-by-step explanation:
A scatter plot shows a relationship between two variables for a particular individual. It is actually a graph where we draw a curve of best fit which can represent the whole data. A scatter plot having the correlation coefficient closest to r = 1, is said to have a very strong correlation between the variables.
A scatter plot would have a strong correlation if the data points of the individual are very close to the line or curve of best fit.
For r = 1 , the correlation is strong and positive.
