Question

What is the class size of class interval 49.5-52.5.​

Answer 1

Step-by-step explanation:

Class Interval = Upper-Class limit – Lower class limit. In statistics, the data is arranged into different classes and the width of such class is called class interval.

52.5 percent *49.5 =

(52.5:100)*49.5 =

(52.5*49.5):100 =

2598.75:100 = 25.9875

Now we have: 52.5 percent of 49.5 = 25.9875

Question: What is 52.5 percent of 49.5?

Percentage solution with steps:

Step 1: Our output value is 49.5.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$49.5=100\%$.

Step 4: Similarly, $x=52.5\%$.

Step 5: This results in a pair of simple equations:

$49.5=100\%(1)$.

$x=52.5\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{49.5}{x}=\frac{100\%}{52.5\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{49.5}=\frac{52.5}{100}$
