Answer:

x = -1.42

Step-by-step explanation:

The quotient of a number x and twelve would be: x/12.

But the problem tells us that seven less than this quotient is 5 times the number. Written as an equation and solving for x this would be:

$\frac{x}{12}-7=5x\\\frac{x-84}{12} =5x\\ x-84=(12)(5x)\\x-84=60x\\-84=59x\\-84/59=x\\-1.42 = x$

Therefore x = -1.42

Exercise 1.A committee of five people is chosen randomly from four men and six women. Find the probability that:a) Exactly four

MatroZZZ [7]

Answer with explanation:

Given : Number of men = 4

Number of women = 6

Total people = $6+4=10$

Total number of ways to make a committee of five people from 10 persons :-

$^{10}C_{4}=\dfrac{10!}{4!(10-4)!}=210$

a) Number of ways to make committee that has exactly four women :

$^6C_4\times ^4C_1=\dfrac{6!}{4!(6-4)!}\times4=60$

The probability that committee has exactly four women :

$\dfrac{60}{210}=\dfrac{2}{7}$

b) Number of ways to make committee that has at-least four women :

$^6C_4\times ^4C_1+^6C_5=\dfrac{6!}{4!(6-4)!}\times4+6=66$

The probability that committee at-least four women :

$\dfrac{66}{210}=\dfrac{22}{70}$

c) Number of ways that committee has more than 4 women :-

$^6C_5\times^4C_0=6$

The probability that committee has more than 4 women :-

$\dfrac{6}{210}$

Now, the probability that committee has at most four women :-

$1-\dfrac{6}{210}=\dfrac{204}{210}=\dfrac{102}{105}$

<h2>Lesson: It's about Using Properties to Simplify Expression.</h2>

Distributive property: a(b+c)=ab+ac

First, you had to remove by parenthesis.

$2*8g$

And then, you multiply by the numbers.

$2*8=16$

Answer: → $=16g$

Hope this helps!
