Solve it:3/10×7/10=21/100
egoroff_w [7]
I'm gonna guess you're asking if the equation is true or false.
Well, the equation is True. 3/10 * 7/10 is 21/100, or in decimal form 0.21.
Converting 21/100 to a decimal is 0.21.
0.21 = 0.21.
21/100 = 21/100.

allochka39001 [22]

Answer:

Answer : A

Step-by-step explanation:

The given data is 25 th percentile is 64, 50th percentile is 74 and 75 th percentile is 80.

percentage : 25    50   75

  score        : 64    74    80

Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.

If the number of observations is odd, then the median is  observation

(\frac{n+1}{2}) ^{th} term

If the number of observations is even, then the median is  observation and  observations.

(\frac{n}{2}+1) ^{th}

given n=3, middle term is '74'

 In this given data the median is (M) = 74

Interquartile range IQR = median of upper half-median of lower half

                                       = 80-64

                                       = 16

                            IQR = 16
