Answer:
Step-by-step explanation:
<u>Midpoint of JK:</u>
- x = (-12 + 8)/2 = -4/2 = -2
- y = (3 - 5)/2 = -2/2 = -1
<u>Slope of the line JK:</u>
- m = (-5 - 3)/(8 - (-12)) = -8/20 = -2/5
Perpendicular lines have negative reciprocal slopes.
So the line r has a slope 5/2 and passes through the point (-2, -1)
<u>Equation of r:</u>
- y = 5/2x + b
- -1 = 5/2(-2) + b
- -1 = -5 + b
- b = 5 - 1
- b = 4
<u>So the equation is:</u>
The answer is X=1+I sqrt 19
Answer:
This means that we are 95% confident that the mean change in HDL (high-density lipoprotein, or "good" cholesterol) of adults eating raw garlic six days a week for six months is between plus or minus 5 milligrams per deciliter of blood (mg/dl) to the sample mean.
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
For 95% confidence interval, it means that we are 95% confident that the mean of the population is between the given upper and lower bounds(margin of error) of the confidence interval.
For the case above, the interpretation of the 95% confidence interval is that we are 95% confident that the mean change in HDL (high-density lipoprotein, or "good" cholesterol) of adults eating raw garlic six days a week for six months is between plus or minus 5 milligrams per deciliter of blood (mg/dl) to the sample mean.
Answer:
» 4:18 and 2:12 are not equivalent.
» 5:20 and 15:60 are equivalent.
» 17:3 and 68:12 are equivalent.
☑ 68:12 is equivalent to 17:3 by a quarter.
☑ 15:60 is equivalent to 5:20 by a third.
Step-by-step explanation:
» Ratios are equivalent only in terms of multiplication and division.
» Considering the greatest ratio;
» Divide it by 4
The radio is 26
because... to find the volume of a cylinder is v=B*h or v= 3.14*r^2*h
V=3.14*26^2*30
V=63679.2
But... rounded to a whole number is equal to 63679
