Answer with explanation:
To find the quotient and remainder ,using area model, when , 6,986 is divided by 8,we will use rectangles of different Dimensions or a single rectangle in this process.
As,width of rectangle will be same that is equal to 8, and Length will vary as how many rectangles you are drawing.
→One way is :
6986 ÷ 8= 873 = Quotient ,and 2=Remainder
So,we can draw a rectangle , having length = 873 unit and Breadth = 8 unit.
And Remainder = 2 Unit,which will be represented by two smaller rectangles.
→→There are other ways also.
You can draw many rectangles , having different Lengths and width of each rectangle being equal to 8.
For, example :
6986 =4000+ 2986
So, length of one rectangle=4000÷8 = 500 unit and Breadth = 8 unit
Length of another rectangle =2986÷8=373 unit and Breadth =8 unit
Quotient = 500 +373=873
and ,Remainder =2 ,which will be represented by two smaller rectangles.
→Now, using Divisibility rule , which states that,
Dividend = Divisor × Quotient + Remainder
6986=873 × 8 +2
As, quotient=873
remainder =2

Answer:
0.0066
Step-by-step explanation:
Given that:
Mean = 75
Variance
The standard deviation
The sample size n = 100
Using the Z table;
P(x > 83.7) = 1 - 0.9934
P(x > 83.7) = 0.0066
Thus, probability = 0.0066
