Answer:
0.0478
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 135 mm
μ is the population mean = 130 mm
σ is the population standard deviation.
We are given variance = 9
Standard deviation = √variance = √9 = 3
Hence
z = 135 - 130/3
z = 1.66667
Probability value from Z-Table:
P(x<135) = 0.95221
P(x>135) = 1 - P(x<135) = 0.04779
Approximately to 4decimal places = 0.0478
Answer:
The coordinates of the point that divides the line internally in the given ratio is (7,3)
Step-by-step explanation:
To find this coordinates, we use the in renal division formula
we have this as;
(x,y) =( nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)
(x1,y1) = (4,-3)
(x2,y2) = (8,5)
(m,n) = (3,1)
So, substituting these values, we have ;
(x,y) = (1(4) + 3)8))/(3 + 1) , (1(-3) + 3)5)/(1 + 3)
(x,y) = (28)/4, (12/4)
(x,y) = (7,3)
