Answer:

The answer is "Option A, D, and E".

Step-by-step explanation:

The choices were missing in the question. so, very first, we defined the choices and then we explain why it will be correct.

Missing data:

A) \  2x+y=-5 \\B) \  y-3=2x \\C) \ x+y=-2 \\D) \ -2x=y \\E) \ 2x=4-y\\

Solve the above value in the form of "\bold{ y = mx + c}", where m= gradient and c= line that cuts on the y-axis.

A) 2x + y = -5\\\\D) -2x = y\\\\E) 2x = 4- y\\\\

A prisoner is trapped in a cell containing three doors. The first door leads to a tunnel that returns him to his cell after two
Greeley [361]

Answer:

The expected number of days until the prisoner reaches freedom is 2.8.

Step-by-step explanation:

Door 1: 0.3 probability of being selected. Leads to his cell after two days' travel.

Door 2: 0.5 probability of being selected. Leads to his cell after four days' travel.

Door 3: 0.2 probability of being selected. Leads to his cell after one day of travel.

What is the expected number of days until the prisoner reaches freedom?

We multiply the probability of each door being used by the time that it leads to the cell. So

E = 0.3*2 + 0.5*4 + 0.2*1 = 2.8

The expected number of days until the prisoner reaches freedom is 2.8.

Fudgin [204]

Answer:

Step-by-step explanation:

total sold amount= 1200+1350=2550

profit amount on first radio= 1200-(1200/1.2)=1000

purchase amount of 1st radio= Rs. 1000

total purchased amount= (2550/1.02) = Rs. 2500

purchase amount of second radio=  2500 - 1000 = Rs. 1500

loss % on second radio= ((1500-1350)/1500 ) * 100 = 10%
