Determine Upper P (Upper F or Upper G )using the general addition rule. Select the correct choice below and fill in any answer b

Lilit [14]

Answer:

S= {8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 }

event F= {10 , 11 , 12 , 13 , 14}

event G= {14 , 15 , 16 , 17}

a) List of outcomes in F or G

answer;

(F or G) = { 10 , 11, 12 , 13 , 14 , 15 , 16 , 17}

b) P ( F or G) = by counting the number of outcomes in F or G

Ans ( F or G) = No. of outcomes in ( F or G) / Total no. of outcomes

= 8/12 = 2/3

c) P ( F or G) using general addition rule

Ans P (F or G) = P(F) = P(G) - P( F and G)

= 5/12 + 4/12 - 1/12

= (5+4-1)/12 = 8/12 =2/3

Define a system of linear inequalities

goblinko [34]

A system of linear inequalities in two variables consists of at least two linear inequalities in the same variables. The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system.

Which of the following lines has a slope of -? a)x + 2y = 0 b)x - 2y = 0 c)-x + 2y = 0

g100num [7]

My mistake, answer must be put in y=mx+b. x+2y=0, you'd want to get y by itself, subtract x and divide by 2y, to get y by its lonely. The slope would be -1/2, the correct answer is A

Rom4ik [11]

Dimensions of walkway and pool= (23+3) x (32+3) => 26ft x 35 ft

Perimeter: 2(l+w)
= 2 (26ft + 35ft)
= 122 ft fence would be required to enclose the walkway and the pool.

Suppose 5 men and 7 women are on a crowded elevator. At the next floor, four people get off the elevator. Find the probability t

Svetach [21]

Answer: $\bold{\dfrac{1}{99}}$

Step-by-step explanation:

There are 5 men and 7 women, which is a total of 12 people. Finding the probability that none of the four people are women is the same as saying that all four people are men.

$\dfrac{5\ men}{12\ total\ people}\ and\ \dfrac{4\ men\ remaining}{11\ people\ remaining}\ and\ \dfrac{3\ men}{10\ people}\ and\ \dfrac{2\ men}{9\ people}\\\\\\=\dfrac{5\times 4\times 3\times 2}{12\times 11\times 10\times 9}\\\\=\dfrac{(4\times 3)\times (2\times 5)}{12\times 11\times 10\times 9}\\\\=\dfrac{1}{11\times 9}\\\\=\dfrac{1}{99}$
