Answer:
-5x - 4
<u><em>Hope this helps!!! :)</em></u>
P(defective) = 3/12 = 1/4
P(good) = 1 - 1/4 = 3/4



The probability that at least 2 units are good is given by:
P(2 good) + P(3 good) + P(4 good) = 0.211 + 0.422 + 0.316 = 0.949.
Answer:
x=-5
Step-by-step explanation:
When finding x, we basically have to isolate the variable. By isolating the variable, usually doing the opposite operation helps it.
Addition is the opposite of Subtraction
Multiplication is the opposite of Division
Let's dive into this problem!
x+7=2
(we need to isolate x. basically we need to get rid of this 7. How do we do this? since it is added by seven, we can subtract it by both sides to get rid of it on the x side.)
x+7=2
-7 -7
x=-5
(subtract 2-(-5), this adds to -5)
This is your final answer.
Answer: 
Step-by-step explanation:
It is important to remember that, by definition, proportional relationships have the following form:

Where "k" is the constant of proportionality.
We know that Maddy assume that the relation between the volume and the weight is proportional.
Then, let be "V" the volume in liters and "w" the weight in kilograms.
We can write the following equation:
So, if the boat of 555 liters weights 7.5 kilograms, we can find "k":

In order to solve the exercise, substitute the value of "k" and
into the equation and solve for "w". Then:
Step 1: 1/10 + 1/10 = 2/10
Step 2: 4/5 - 2/10
GCF: multiply both sides of 4/5 by 2 = 8/10
Step 3: 8/10 - 2-10 = 6/10
ANSWER: C <span>fraction 6 over 10, because fraction 4 over 5 minus 2 times fraction 1 over 10 equals fraction 4 over 5 minus fraction 2 over 10 </span>
