Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 30}}}}}$

Step-by-step explanation:

$\sf{1200 - 5(3x + 30) = 600}$

Distribute 5 through the parentheses

$\dashrightarrow{ \sf{1200 - 15x - 150 = 600}}$

Subtract the numbers: 150 from 1200

$\dashrightarrow{ \sf{ - 15x + 1050 = 600}}$

Move 1050 to right hand side and change it's sign

$\dashrightarrow{ \sf{ - 15x = 600 - 1050}}$

Subtract 1050 from 600

$\dashrightarrow{ \sf{ - 15x = 450}}$

Divide both sides of the equation by -15

$\dashrightarrow{ \sf{ \frac{ - 15x}{ - 15} = \frac{ - 450}{ - 15} }}$

Calculate

$\dashrightarrow{ \sf{x = 30}}$

Hope I helped!

Best regards! :D

Answer:

x=+30

Step-by-step explanation:

1200-5(3x+30)=600

We move all terms to the left:

1200-5(3x+30)-(600)=0

We add all the numbers together, and all the variables

-5(3x+30)+600=0

We multiply parentheses

-15x-150+600=0

We add all the numbers together, and all the variables

-15x+450=0

We move all terms containing x to the left, all other terms to the right

-15x=-450

x=-450/-15

x=+30

6. Suppose that a fair coin is tossed 2 times, and the result of each toss (H or T) is recorded.

nekit [7.7K]

Answer:

a) $S= {HH, HT, TH, TT}$

b) $P(X=0) = (2C0) (0.5)^0 (1-0.5)^{2-0}= 0.25$

$P(X=1) = (2C1) (0.5)^1 (1-0.5)^{2-1}= 0.5$

$P(X=2) = (2C2) (0.5)^2 (1-0.5)^{2-2}= 0.25$

And we have the following table:

X | 0 | 1 | 2

P(X) | 0.25 | 0.5 | 0.25

Step-by-step explanation:

Let's define first some notation

H= represent a head for the coin tossed

T= represent tails for the coin tossed

We are going to toss a coin 2 times so then the size of the sample size is $2^2 = 4$

a. What is the sample space for this chance experiment?

The sampling space on this case is given by:

$S= {HH, HT, TH, TT}$

b. For this chance experiment, give the probability distribution for the random variable of the total number of heads observed.

The possible values for the number of heads are X=0,1,2. If we assume a fair coin then the probability of obtain heads is the same probability of obtain tails and we can find the distribution like this:

$P(X=0) = (2C0) (0.5)^0 (1-0.5)^{2-0}= 0.25$

$P(X=1) = (2C1) (0.5)^1 (1-0.5)^{2-1}= 0.5$

$P(X=2) = (2C2) (0.5)^2 (1-0.5)^{2-2}= 0.25$

And we have the following table:

X | 0 | 1 | 2

P(X) | 0.25 | 0.5 | 0.25

Answer:

x=5

y=7

z=6

Step-by-step explanation:

I know because Figure 1 the number is 9 and in figure 2 the number is 3 so it must of divided by 3.

15/3=5

21/3=7

18/3=6
