{\qquad\qquad\huge\underline{{\sf Answer}}}

Let's solve ~

\qquad \sf  \dashrightarrow \: (h - g)(x)

\qquad \sf  \dashrightarrow \: h(x) - g(x)

\qquad \sf  \dashrightarrow \:  {x}^{2}  + 2x - 6 - (2 {x}^{2}  + 3x - 9)

\qquad \sf  \dashrightarrow \:  {x}^{2}  + 2x - 6 - 2 {x}^{2}   -  3x  +  9

\qquad \sf  \dashrightarrow \:  {x}^{2}  - 2 {x}^{2}  + 2x - 3x - 6 + 9

\qquad \sf  \dashrightarrow \:  -  {x}^{2}  - x + 3

For, (h - g)(2.1), put x = 2.1

\qquad \sf  \dashrightarrow \:  -  {(2.1)}^{2}  - (2.1) + 3

\qquad \sf  \dashrightarrow \:  - 4.41 - 2.1 + 3

\qquad \sf  \dashrightarrow \:  - 6.51 + 3

\qquad \sf  \dashrightarrow \:  - 3.51

The weekly incomes of a large group of executives are normally distributed with a mean of $2,000 and a standard deviation of $10
cestrela7 [59]

Let X be the weekly incomes of a large group of executives. The weekly incomes of a large group of executives follows Normal distribution with mean $2000 and standard deviation $100.

μ =2000, σ =100

We have to find z score for income $2100 i.e x=2100

Z = \frac{x-mean}{standard deviation}

= \frac{2100 - 2000}{100}

Z = 100/100

Z = 1

The z score for income $2100 is 1

In a rock-paper-scissors game, a winner gets 5 points and a loser gets 2 points. After a man played this game 20 times, his tota
aleksandr82 [10.1K]

Answer:

The man wins 9 times and looses 11 times in the rock - paper-scissor game.

Step-by-step explanation:

Let us assume that in the game:

Number of times  man wins the games = x times

Number of times  man loses the games = y times

Total number of attempts = 20

Points after winning = 5

Points after loosing = 2

Now, according to the question:

       x  + y =20

and 5 x + 2 y = 67

Now, from (1) y = 20-x,     put in (2)

5x + 2y = 67       ⇒           5x + 2(20 -x)  = 67

or, 5x -2x = 67 - 40

or, 3x = 27

⇒ x = 27/3 = 9

then y = 20 - x = 20 - 9 = 11

⇒ x = 9 and y = 11 is the solution of the given system.

Hence, the man wins 9 times and looses 11 times in the rock - paper-scissor game.
