Eva8 [605]

Answer:  C. 11/15

Step-by-step explanation:

Given : The fraction of stores inventory is children's clothing=\dfrac{1}{3}

The fraction of stores inventory is women's clothing=\dfrac{2}{5}

Since both events are independent.

Therefore, the fraction of the total inventory is children's or women's clothing =  (Fraction of stores inventory is children's clothing ) + (Fraction of stores inventory is women's clothing )

=\dfrac{1}{3}+\dfrac{2}{5}=\dfrac{5+2(3)}{15}

=\dfrac{11}{15}

∴ The fraction of the total inventory is children's or women's clothing =\dfrac{11}{15}

Hence, the correct answer is C. 11/15 .

Rudik [331]

Answer:

v = 2034.72 mm³

Step-by-step explanation:

radius = 18mm

height = 6mm

pi = 3.14

v = πr²h/3

v = 3.14 * (18mm)² x 6mm/3

v = 3.14 * 324mm²  x 2mm

v = 2034.72 mm³
