Answer:At 95% confidence interval, the lower end is 64.306 and the upper end is 64.614
At 98% confidence interval, the lower end is 64.268 and the upper end is 64.652
Step-by-step explanation:
Answer:
(3,2)
Step-by-step explanation:
Y=-2x+8 equation 1
y=x-1 equation 2
x-1=-2x+8 substi y of second equation into y of first equation.
3x=9
x=3
solve for y by putting the x value into either equation
y=x-1
y=3-1
y=2
A- they are parallel because they have equal slopes.
A=((40+64)/2)*18= 936 units^2
Answer:
X= -45
Step-by-step explanation:
If graphed on desmos, the line touches the x axis at (-45,0)
Also, if in the equation you substitute y for 0, then you will get -45
