Answer: X=-3

Step-by-step explanation:

3x-7(4+2x)=-x+2

I would apply the BODMAS rule here by first trying to eliminate the brackets.

To do this I will multiply -7 by (4+2x) =-28-14x. Now the equation becomes 3x-28-14x=-x+2. We collect like terms. 3x-14x+x=2+28. -10x=30. We would divide both sides by -10 to get our X. We have X=-3

Dafna11 [192]

Answer:

a) 2/3

b) 1/3

Step-by-step explanation:

Let X be the random event that measures the time you will have to wait.  

Since time is uniformly distributed between 10 and 10:30 in intervals of 1 minute

P(n < X ≤ n+1) = 1/30 for every minute n=0,1,...29.

a)

P( X > 10) = 1 - P(X ≤ 10) = 1 - 10/30 = 2/3

b)

P(10 <  X ≤ 20) = (20-10)/30 = 1/3

Which inequality has a dashed boundary line when graphed? A y&gt;=3/5x+1 B y&gt;= -1/3x+1 C y&gt;3x+1
Ket [755]

Answer: C y>3x+1

Step-by-step explanation:

  • When we graph an  inequality with strictly greater of less than sign ('<' or '>'), then the graph has a dashed boundary line .
  • Further it indicates that it does not include the points on the line.

From all the given options , only C contains inequality with '>' sign .

Hence, y>3x+1 is the inequality has a dashed boundary line when graphed.

hence, the correct option is C.
