A sample of 23 cigarettes contained an average of 40 milligrams of nicotine. If the sample standard deviation was s = 1.8 milligrams, then find the 95% confidence interval for the mean amount (in milligrams) of nicotine in the sampled brand of cigarettes.​

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

care to share were the trapezoid shown is ?

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
