Answer:I wrote it on paper look at it carefully.
Step-by-step explanation:
Answer:
the Point is (12,6)
Step-by-step explanation:
We Have Formula ( (b*x1 +a*x2)/a+b , b*y1 +a*y2/a+b)
Where x1 , y1, and x2, y2, are the coordinate points of the line segment that make the line segment. And 'a' and 'b' is the ratio. here the ratio is 3:2 so the a =3 and b=2 . After putting values and of the points and the ratio in the above formula we'll have
(2*0 +3*20)/3+2 , (2*15 + 3*0)/3+2
we'll have 60/5 , 30/5 = (12,6) this will the point that will divides the Libe segment formed from A and B in the Ratio of 3:2.
Oliver is collecting Quantitative data , is that a choice?
Step-by-step explanation:
1. (4m² - 1.5m + 2) + (9m - 2m³ + 2m)
= 4m² - 1.5m + 2 + 9m - 2m³ + 2m
= 4m² + (-1.5m + 9m + 2m) + 2 + 2m³
= 4m² + 9.5m + 2 + 2m³
= 2m³ + 4m² + 9.5m + 2
2. (-3y + 2y² - 6) + (3y + 4y² + x)
= -3y + 2y² - 6 + 3y + 4y² + x
= (-3y + 3y) + (2y² + 4y²) - 6 + x
= 0y + 6y² - 6 + x
= 6y² - 6 + x
Firstly, put Derek and Paul's collection together:
1950, 1952, 1908, 1902, 1955, 1954, 1901, 1910, 1929, 1935, 1928, 1930, 1925, 1932, 1933, 1920
1950+1952+1908+1902+1955+1954+ 1901+1910+1929+1935+1928+1930+ 1925+ 1932+1933+1920
=30864
=30864÷16
=1929
∴the mean is 1929.
Median:
1901, 1902, 1908, 1910, 1920, 1925, 1928, 1929, 1930, 1932, 1933, 1935,
1950, 1952, 1954, 1955
1930÷1929
=1.0005184
= Median
Range:
1955-1901
=54
∴the range is 54.
