Answer:
0.4494
Step-by-step explanation:
Given :
marks number of students
20-29 8
30-39 12
40-49 20
50-59 7
60-69 3
The range Coefficient is obtained thus :
Range Coefficient = (Xm - Xl) / (Xm + Xl)
Where ;
Xm = Mid value of highest class = (60+69)/2 = 64.5
Xl = Mid value of lowest class = (20+29)/2 = 24.5
Range Coefficient = (64.5 - 24.5) / (64.5 + 24.5)
Range Coefficient = 40 / 89 = 0.4494
Answer:
Table shown below
Step-by-step explanation:
Table shown below
To solve this problem let's use proportions.
If 2 pounds of grapes cost $6, half the amount will cost half the dollars, so the last row will have $3 in the price
For the second row, we know the price is $1, that is, one-sixth of the original given price. It should correspond to one-sixth of the amount of grapes or 2/6 pounds.
Simplifying the fraction, we get 1/3 or 0.33 pounds
Answer:
Linear-1,2,3,6
Nin-Linear-4,5
Step-by-step explanation:
A linear equation is an equation in which the highest power of the variable is 1.
Out of the given equations, the following are linear.
1) 
2) 
3) 
6) 
These equations on the other hand are nonlinear.
4) 
5) 
No 4 contains a term which is the product of two variables therefore it is not linear.
No 5 contains a term whose highest power is 3. Such an equation is a Cubic Equation.
