Archy [21]

Answer:

$\frac{360}{n}$

Step-by-step explanation:

Given:

The above statements

Required

Complete the above statements

Considering the third statement in the question;

First, it should be noted that a circle is a full sector that measures 360 degrees

Assuming the circle is divided by a central angle of 180, the number of sectors formed will be;

$\frac{360}{180} = 2\ sectors$

Further assume the circle is divided by a central angle of 90, the number of sectors formed will be;

$\frac{360}{90} = 4\ sectors$

Similarly, if the circle is divided by a central angle of n, the number of sectors formed will be;

$\frac{360}{n}$

Hence, from the list of given options; $\frac{360}{n}$ fills the gap correctly

Dima020 [189]

Answer:

1/14

Step-by-step explanation:

Let A represent the event First person getting red velvet cake
Let B represent the event Second person getting red velvet cake

P(A) = Total number of Red Velvet Cakes ÷ Total Number of Cakes =

6/21 = 2/7

If the first person gets a red velvet cake, then there are 5 red velvet cakes and 20 total cakes

Therefore P(B|A) = Number of red velvet cakes left ÷ total number of cakes left = 5/20 = 1/4

P(A and B) == probability of both getting red velvet cake P(A∩B) = P(A).P(B|A) = 2/7 × 1/4 = 2/28 = 1/14
