A country has two political parties, the Demonstrators and the Repudiators. Suppose that the national senate consists of 100 mem

IRISSAK [1]

Answer:

(a) 4.148 x 10^(12) ways

(b) 5,827,360 ways

Step-by-step explanation:

Number of Demonstrators (D) = 44

Number of Repudiators (R) = 56

(a)

5 senate members must be Repudiators and 5 must be demonstrators, assuming that the order at which they are selected is irrelevant:

$N= C^{D}_{5} * C^{R}_{5}\\N=\frac{56!}{5!(56-5)!} *\frac{44!}{5!(44-5)!} \\N=3,819,816*1,086,008\\N=4.148 *10^{12}$

(b)

Since there are two different positions, (speaker and vice speaker), order is important in this situation, and the total number of ways to select two senators from each party is:

$N= P^{D}_{2} * P^{R}_{2}\\N=\frac{56!}{(56-2)!} *\frac{44!}{(44-2)!} \\N=3,080*1,892\\N=5,827,360$

AH the second question

Degger [83]

Answer:

ii. 55 degrees.

Step-by-step explanation:

(ii)

Consider the quadrilateral ABCD.

Angle n = 180 - 96 = 84 degrees ( opposite angles of a cyclic quadrilateral are supplementary).

Consider triangle ABC: the 3 angles are supplementary, so

m < j = 180 - 84 - 41

= 55 degrees.
