Answer:
We can conclude that the difference between the two means are between -0.223 and 0.988.
And for this case the confidence interval contains the value of 0 so then we have enough evidence to conclude that we don't have significant difference between the means of Silver Queen and the Country Gentlemen.
Step-by-step explanation:
For this case we have the following interval for the difference between Silver Queen - Country Gentlemen:
We can conclude that the difference between the two means are between -0.223 and 0.988.

Answer:
Step-by-step explanation:
The given equation is
The slope of this line
Since all parallel lines have the same slope, the slope of our line is also m=1.
We now use the point-slope formula
Since the line passes through (-1,-1)
We gave
We substitute the slope and point to get
Answer:
322.9 ft
Step-by-step explanation:
See attachment for the diagram
ro: radius of outer circle
ri: radius of inner circle
Length of inner railing= circumference of inner semi-circle+ twice of inner horizontal sides
Length of inner railing= ri+ 2×(70- ro)
= × 45/2+ 2×(70-65/2)
=145.71 ft
Lenth of outer railing= circumference of outer semi-circle+ twice of outer horizontal sides
= ro+ 2×(70- ro)
= × (65/2) + 2×(70-65/2)
=177.14ft
Total length of railing =177.14+145.71
= 322.85ft
