Answer:

Follows are the solution to this question:

Step-by-step explanation:

In this question, we apply the associative property that calculates the given  value, which can be defined as follows:  

Rule:

\bold{\to (A\times B)\times C=  A \times (B\times C)}

Let,

A= 5\\B=120\\C=6.232

put the value in the above rule:

Solve L.H.S part:

\to (5\times 120)\times 6.232\\\\\to (600)\times 6.232\\\\\to 3,739.2

Solve R.H.S part:

\to 5 \times (120 \times 6.232)\\\\\to 5 \times 747.84\\\\\to 3,739.2

So, L.H.S=R.H.S

A political polling organization wishes to select a smaller focus group from a group of 7 Republicans, 10 Democrats, and 2 Indep
Alina [70]

Answer:

a) 1470 ways

b) 2835 ways

Step-by-step explanation:

the question is not correct, in the correct question The number of independents should be 3 not 2

there are 7 republicans, 10 democrats and 3 independents.

C(n,r) is the number of different combinations of n distinct objects taken r at a time.

C(n,r) = \frac{n!}{(n-r)!r!}

a) it will consist of 1 Republican and 4 Democrats

The number of ways this can be chosen is = C(7,1) × C(10,4) = \frac{7!}{(7-1)!1!}  * \frac{10!}{(10-4)!4!} = 7 × 210 = 1470 ways

(b) it will consist of 2 Republicans, 2 Democrats, and 2 Independents (consist of 2 independents not 3)

The number of ways this can be chosen is = C(7,2) × C(10,2) × C(2,2)

 =\frac{7!}{(7-2)!2!}  * \frac{10!}{(10-2)!2!}* \frac{3!}{(3-2)!2!} = 21 × 45 × 3 = 2835 ways

Factorise 4b^2 + 16b
lubasha [3.4K]
Factorise 4b² + 16b  ⇒ 4b(b+4)

expand (a-1)(a-2) ⇒ a(a-2) - 1(a-2) ⇒ a² - 2a - 1a + 2 ⇒a² - 3a + 2

factorise x² + 8x + 7 ⇒(x + 1) (x + 7)

evaluate y⁶ / y² ⇒ y * y * y * y * y * y / y * y = y⁴

if x = -1 and y = 5, find z when z = x² + 2y² ;
z = -1² + 2(5²) ⇒ 1 + 2(25) ⇒1 + 50 = 51

Make x the subject: y = 4x - 3
     y = 4x - 3
<u>+3            +3</u>
3 + y = 4x
<u>÷4        ÷4    </u>
(3+y)/4 = x
