Queston 4: The range of the relation is : (-2,4)

Question 5: the domain of the relation is:
{2, 2.1, 5.1, 5.5, 6}

Question 6: The relation is not a function because it two of the x value have the same y values. Therefore it is not a function as it does not pass the vertical line test.
(-4, 0) and (-3, 0) both have 0 for the y coordinate. A function can’t have this.

Step One is to add up all the values
6.5+5+6+5.5+7+4+4.5+5+6+5.5+4+7.5+6+7+8+5+6+6.5+6.5+5 = 116.5

Step Two is to divide the result from step one by 20 (since there are 20 values added up)
116.5/20 = 5.825

The sample mean is 5.825

Answer:

The rate of Simple Interest is 6.5 %

Step-by-step explanation:

Given as :

Principal = $ 4000.00

Amount = $ 5300.00

The time period of loan = 5 years

Let The rate of simple interest = R

Now,

From Simple Interest method

Simple Interest = $\frac{Principal\times Rate\times Time}{100}$

And , Simple Interest = Amount - Principal

So , Simple Interest = $ 5300.00 - $ 4000.00

Or, Simple Interest = $ 1300

Now, Simple Interest = $\frac{Principal\times Rate\times Time}{100}$

So, $ 1300 = $\frac{ 4000\times Rate\times 5}{100}$

Or, $ 1300 × 100 = $ 4000 × Rate × 5

Or, Rate = $\frac{1300\times 100}{4000\times 5}$

Or, Rate = 6.5

Hence The rate of Simple Interest is 6.5 % Answer
