Using synthetic division, with divisor -4 stemming from factor (x+4), we find the coefficients of the quotient:
____________________
-4 / -3 -4 2
12 -2
------------------------------------
-3 8 0
The quotient is then -3x + 8, using the coefficients derived using synth. div.
Answer : option A
To find the range of scores that represents the middle 50 % of the student who took the test , we find inter quartile
Inter quartile range is the middle 50% of the given range of scores.
The difference between the upper quartile and lower quartile is the inter quartile that is middle 50%
From the diagram , we can see that
Upper quartile = 89
lower quartile = 65
So range is 65% to 89%
Answer:
14, 16, 18
Step-by-step explanation:
x + (x+2) + (x+4)= 48
3x + 6 = 48
3x = 42
x = 14
x+2 = 16
x+4 = 18
Hi!
50) The answer is 104 cm
Steps:
-recognize that the shape is a triangle and a rectangle put together
-find the measurements of the triangle (8&6) and the rectangle (8&10)
-find the areas of the triangle (l x h divided by 2= a) and the rectangle (l x h+a)
-add the areas together (24& 80)
51) The answer is 800ft
Steps:
-split the irregular shape into a triangle and a rectangle
-find the area of both the triangle (200) and of the rectangle (600)
-add together (200+600= 800)
52) The answer is 156 cm
Steps:
-recognize that the shape can be split into 3 rectangles
-find the measurements for all three rectangles (12&5, 12&6, 3&8)
-Use the formula l x h= a for each rectangle
-add each one of the rectangles together (60, 72, &24)
