Lcm of 420 and 210

MATHS

LCM = 420

Step-by-step explanation:

What is the LCM of 210 and 420?

Step 1:

Find the prime factorization of 210

210 = 2 × 3 × 5 × 7

Step 2:

Find the prime factorization of 420

420 = 2 × 2 × 3 × 5 × 7

Step 3:

Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 2 × 3 × 5 × 7

Step 4:

The required LCM

LCM = 420

Therefore, we conclude that:

LCM = 420

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
