The answer to this question would be Y= -4/3 X - 4. This is because y can't be negative. So, when you go to put -3y=4x+12 together (which is the correct form) you have to make sure your y is positive and then isolate your variables (divide by -3)
Answer: The equation using one variable that can be used to find the total number of pounds of milk chocolate and caramels in the candy is 
x= Weight of candy in pounds
0.9x = Weight of milk chocolate.
Step-by-step explanation:
Given, Martin is making a candy that contains 90% milk chocolate and the rest caramels. The candy has 3 pounds of caramels.
Let x= Weight of candy in pounds
Then, 0.9x = Weight of milk chocolate.
Then, According to the question
So, Weight of milk chocolate. = 
Hence, the equation using one variable that can be used to find the total number of pounds of milk chocolate and caramels in the candy is
Answer:
P ( Z < 72 ) = 0.8577 or P ( Z < 72 ) = 85.77 %
Step-by-step explanation:
We know:
-A normal distribution
-Mean μ = 69.0 in
-Standard deviation σ = 2.8 in
- Population n = 350
And doors height 72 in
If passengers will pass through the door without bending that means he must be under 72 in tall, therefore we are looking for the probability of men under 72 in, to find such probability we compute the value of Z according to
Z = ( X - μ ) / σ ⇒ Z = ( 72 - 69 ) / 2.8
Z = 1.07
Now with this value we look the Z tables, to find a value of: 0.8577
So the probability of select a men and that he can fit through the door is
P ( Z < 72 ) = 0.8577 or P ( Z < 72 ) = 85.77 %
Answer:
The answer is y = 5.25
Step-by-step explanation:
-2.3 + 1.6y = 6.1
1.6y = 6.1 + 2.3
1.6y = 8.4
y = 8.4/1.6
y = 5.25
