Answer:
Step-by-step explanation:
Number of phones broken = 3
Number of phones not broken = 15
Total number of phone in the shipment = 18
Since a not broken phone has been randomly selected, the number of phones not broken reduces to 14. And the total number of phones would be 17.
Pr(of newly selected phone NOT broken) = 
=
Therefore, the probability of the selected phone not being broken is .

Answer:
Step-by-step explanation:
3p – 1 = 5(p – 1) – 2(7 – 2p) 3 -9 -10 First Distribute
3p-1= 5p-5-42+12p-9-10 Simplify all like factors
3p-1=17p-66 Add 66 on both sides
3p+65=17p Subtract 3p from both sides
65=15p Divide both sides by 15
p=4.3
if it is a 100
3p – 1 = 5(p – 1) – 2(7 – 2p) 3 -9 -100 First Distribute
3p-1= 5p-5-42+12p-9-100 Simplify all like factors
3p-1=17p-156 Add 156 on both sides
3p+155=17p Subtract 3p on both sides
155= 15p divide both sides by 15
10.3=p
y = 6 - 3x
x + y = 62
Since we already know the value of y, we can use substitution to find the value of x.
x + 6 - 3x = 62
<em><u>Subtract 6 from both sides.</u></em>
x - 3x = 56
<em><u>Combine like terms.</u></em>
-2x = 56
<em><u>Divide both sides by -2</u></em>
x = -28
Now that we know the value of x, we can solve for the value of y.
x + y = 62
-28 + y = 62
<em><u>Add 28 to both sides</u></em>
y = 90
The value of y is 90, and the value of x is -28 (this is your answer)
To make sure that these values are correct, we can plug them into the original equations.
y = 6 - 3x
x + y = 62
90 = 6 - 3(-28)
90 = 90 √ this is correct
-28 + 90 = 62
62 = 62 √ this is also correct
