Answer:

Range = 29

Variance=   (X₁- U) ² / N= 973/10 = 97.3

Standard Deviation= √variance= √97.3=  9.864

Step-by-step explanation:

Range = Difference between the highest and lowest value = 97-68= 29

Variance

u=  ∑X₁ /10=800/10=80

Variance=   (X₁- U) ² / N= 973/10 = 97.3

Standard Deviation= √variance= √97.3=  9.864

(b) The important feature of the data is not revealed through the different measures of​ variation is that the variability of two or more than two sets of data cannot be compared unless a relative measure of dispersion is used .

Lisa is stringing beads to make a necklace, anklet, and a bracelet. The necklace uses 50% of the string. The anklet is 60% short
Sergeeva-Olga [200]

Answer:

The Original length of uncut String is of 120 cm.

Step-by-step explanation:

Let the length of original string be x.

Length of bracelet = 18 cm.

The necklace uses 50% of the string

Hence length of necklace will be equal to 50% of the string.

Length of necklace = \frac{50}{100}\timesx =0.5x

The anklet is 60% shorter than the necklace.

Length of anklet will be equal to difference of Length of necklace and 60%  of the Length of necklace.

Length of anklet = 0.5x-\frac{60}{100}\times0.5x = 0.5x-0.3x = 0.2x

The bracelet needs 25% less string than the anklet.

Length of bracelet will be equal to difference of Length of anklet and 25%  of the Length of anklet.

Length of bracelet = 0.2x-\frac{25}{100}\times0.2x = 0.2x-0.05x = 0.15x

But Length of Bracelet = 18 cm

\therefore 0.15x=18\ cm\\\\x = \frac{18}{0.15}\ cm = 120\ cm

Hence Total original Length of Uncut String is 120 cm.
