Matter exists in three states; <em>solid, liquid and gas.</em>

The statement that corrects the error in his table is:

<em>D. The Solids column and the gas column should be switched because solids have a definite shape and volume and gases have no definite shape or volume. </em>

<em />

<em />

Looking at the table, we have the following observations.

  • <em>The solid column shows indefinite shape (because the particles fill in the container)</em>
  • <em>The liquid column is properly cataloged</em>
  • <em>The gas column shows a definite shape</em>

<em />

Solid has definite shape, while gas doesn't.

To make corrections, Marcus needs to switch the gas and the solid column.

You play two games against the same opponent. The probability you win the first game is 0.4. If you win the first game, the prob
Ilia_Sergeevich [38]

Answer:

a) No

b) 42%

c) 8%

d) X               0                 1                2

   P(X)           42%            50%         8%

e) 0.62

Step-by-step explanation:

a) No, the two games are not independent because the the probability you win the second game is dependent on the probability that you win or lose the second game.

b) P(lose first game) = 1 - P(win first game) = 1 - 0.4 = 0.6

P(lose second game) = 1 - P(win second game) = 1 - 0.3 = 0.7

P(lose both games) = P(lose first game)  × P(lose second game) = 0.6 × 0.7 = 0.42 = 42%

c)   P(win first game)  = 0.4

P(win second game) = 0.2

P(win both games) = P(win first game)  × P(win second game) = 0.4 × 0.2 = 0.08 = 8%

d) X               0                 1                2

   P(X)           42%            50%         8%

P(X = 0)  =  P(lose both games) = P(lose first game)  × P(lose second game) = 0.6 × 0.7 = 0.42 = 42%

P(X = 1) = [ P(lose first game)  × P(win second game)] + [ P(win first game)  × P(lose second game)] = ( 0.6 × 0.3) + (0.4 × 0.8) = 0.18 + 0.32 = 0.5 = 50%

e) The expected value  \mu=\Sigma}xP(x)= (0*0.42)+(1*0.5)+(2*0.08)=0.66

f) Variance \sigma^2=\Sigma(x-\mu^2)p(x)= (0-0.66)^2*0.42+ (1-0.66)^2*0.5+ (2-0.66)^2*0.08=0.3844

Standard deviation \sigma=\sqrt{variance} = \sqrt{0.3844}=0.62

Use the net to find the surface area of the regular pyramid.
Svetradugi [14.3K]

Answer:

7 or 7^{2}

Step-by-step explanation:

Each triangle has the surface area of 1.5, because 1 * 3 = 3 / 2 = 1.5. You divide by two because it is half a rectangle instead of a full one. You multiply by four which would get you 1.5 * 4 = 6. The square in the middle has the surface area of 1 because 1 * 1 = 1. So you would get 7.
