Bob has a garden
the area is 75 square feet
the legnth is 3 times the width
solve
75=lw
l=3w
subsitute
75=3w times w=3w^2
75=3w^2
sdivide by 3
25=w^2
square root
5=width
subsitute
3w=l
3 times 5=l
l=15
width=5
legnth=15
1.15/3 = 20 minutes worth = 0.383
60 minutes+20 minutes=80 minutes = 1.15+0.383=1.53
1.5/3 = 0.5 = 20 minutes
60 minutes+20 minutes=80 minutes =1.5+0.5=2
2-1.53=0.47 therefore it is 0.47 minutes quicker with Model A
Answer: The standard error for sample is 0.0686 .
Step-by-step explanation:
We know that the formula to find the standard error is given by :-

, where s = standard deviation
n= Sample size
As per given , we have
s= $0.4 and n= 34
Then , the standard error for sample is given by :-

Hence , the standard error for sample is 0.0686 .
Answer:
23
Step-by-step explanation:
(0,4) and (3,-8) has segment of slope -8-4 / 3-0 = -12/3 = -4. y intercept is given to us as 4
equation is
y-4=-4(x) in point slope form
y+8=-4(x-3) using the other point
y=-4x+4 in slope intercept form
4x+y=4 in standard form
