Area : height x width
perimeter : 2(length + width)
Is this question multiple choice or can you just write a random perfect square number? An example of one would be 25
Solution:
Array is arrangement of numbers in terms of rows and columns either by rectangles or squares.
So,if an array has 32 squares
The possible arrangements are
32 = 8× 4 or 4× 8
= 16×2 or 2×16
= 1 ×32 or 32 ×1
Here first entry denotes number of rows and second entry denotes number of columns.
You'll need to calculate the applicable z-score:
(given value of x) - (mean value)
z = -----------------------------------------------
standard deviation
370-400 -30
Here, z = --------------- = ---------- = -0.3
100 100
Use either a table of z scores or your calculator to determine the area under the standard normal curve to the left of z = -0.3.
According to my TI-83 Plus calculator, this area is 0.382.
The probability of selecting at random a score less than or equal to 370 is 0.382.
