Answer
h = 8.12 cm
Explanation
Area of a parallelogram = b • h
We know the area is 20.3 cm^2 and that the base is 2.5cm.
Therefore 20.3 cm^2 = 2.5h
20.3/2.5 = 8.12 cm
h = 8.12 cm
Answer:
27.2 ft
Step-by-step explanation:
Since 1 in on the drawing = 8 ft, we should find out how much ft is 3.4 in.
So, to get from 1 to 8, we multiply by 8.
And since we multiply by 8, we also have to do it to the other part as well.
So we would do:
8 x 3.4 = 27.2
Hope this helps! :)
no thanks but I'll see if I can get friends to join
Answer:
c) 
Step-by-step explanation:
Equation for regression line of y on x is given as
where
= predicted value
m = slope of line
b = intercept
m and b are found as
r = correlation coefficient = 0.88
Sx = standard deviation for independent variable x = 13
Sy = standard deviation for dependent variable y = 27
= mean value of independent variable x = 21
= mean value of dependent variable y = 55
Substituting these values in (2) and (3)
Putting these values of m and b in (1)
That would be 37.5 percent
