Serhud [2]

Answer:

Arc length is 12436.8m

Step-by-step explanation:

arc length  = \frac{M degree}{360degree} * πD

where M is the angle measure of the arc

and D is the diameter

considering the earth as a circle and half the earth as a semi circle the angle measure of the arc will be = 180 degrees

\frac{180}{360} * π * 7917.5 = 12436.8m

We have been given that

stock XYZ opened at $6.12 and it closed at $6.88 and we have find the rate of change of stock.

Change in the value =| Initial - final |

Change in the value = |6.12-6.88|

Change in the value = 0.76

Hence, the rate of change of stock is given by

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 .
