In rectangle ABCD, point E lies halfway between sides AB and CD and halfway between sides AD and BC. If AB=6 and BC=9, what is the area of the shaded region? Write your answer as a decimal, if necessary. Do not include units in your answer.
Answer:
Height=9/2=4.5
A=1/2*b*h
A=1/2*6*4.5
A=13.5
13.5*2=27
The area of the shaded region is 27.
If 2300 square centimeters of material is available to make a box with a square base and an open top, find the largest possible volume of the box. Volume
Answer:
12,949.0563cm³Step-by-step explanation:
Let the volume of the box be V = x²h
x is the length of one side of the square base
h is the height of the box;
Also let the surface area S = x² + 2xh + 2xh (open at the top)
S = x²+4xh
Given
S = 2300sq.cm
2300 = x²+4xh
make h the subject of the formula;
2300-x² = 4xh
h = (2300-x²)/4x
Substitute this expression into the volume formula
V = x²y
V = x²(2300-x²)/4x
V = x(2300-x²)/4
V = 1/4(2300x - x³)
To maximize the volume, dV/dx = 0
dV/dx = 1/4(2300- 3x²)
1/4(2300- 3x²) = 0
cross multiply
2300-3x² = 0
2300 = 3x²
x² = 2300/3
x² = 766.67
x = √766.67
x = 22.69cm
Since h = (2300-x²)/4x
h = 2300 - 766.67/4(22.69)
h = 1533.33/90.76
h = 16.89cm
Volume = 766.67(16.89)
Volume = 12,949.0563cm³
Hence the largest possible volume of the box is 12,949.0563cm³

give an example of an instance when correlation and significance are extremely important when comparing sets of data
Answer:
A paediatric registrar has measured the pulmonary anatomical dead space (in ml) and height (in cm) of 15 children. The data are given in table 11.1 and the scatter diagram shown in figure 11.2 Each dot represents one child, and it is placed at the point corresponding to the measurement of the height (horizontal axis) and the dead space (vertical axis). The registrar now inspects the pattern to see whether it seems likely that the area covered by the dots centres on a straight line or whether a curved line is needed. In this case the paediatrician decides that a straight line can adequately describe the general trend of the dots. His next step will therefore be to calculate the correlation coefficient.

Answer:
Seats: 180, 225, 315, 405
Rows: 4, 5, 7, 9
Step-by-step explanation:
225 divided by 5 is 45, if you multiply the number of rows by 45, then you will get the number of seats.

For a science project, Daniel planted 51 flower seeds. Of those seeds, 12 did not grow at all. Of the seeds that did grow, 2/3 of them grew green tomatoes. How many green tomatoes grew?
Answer:
34
Step-by-step explanation:
51*2/3=34
Answer:
26
Step-by-step explanation:
Do 51-12 first because those did not grow which is 39. Then divide 39 by 3 and you get 13. That is one third of the plants that grew, so you now have to multiply by two. 13 times 2 is 26, so that would be your answer.
