Answer:
x = 1
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 12 when x = - 2, then
k = 
= 
= - 6, thus
y = - 6x ← equation of variation
When y = - 6, then
- 6 = - 6x ( divide both sides by - 6 )
x = 1
Answer:
Step-by-step explanation:
Given that there are two machines available for cutting corks intended for use in wine bottles.
X1 = diameter of I machine and X2 = diameter of II machine
X1 is N(3.04, 0.02) and X2 is N(2.9, 3.1)
Acceptable is mean =3 and std dev = 0.1
a) 
b) 
Both are certain events.
This problem is very simple. All you have to do is add 10 and 9. The correct answer is D.
The answer is B
If you multiply each price by .15 then subtract it example below.
48.00 × .15 = 7.20
Then subtract that number to the price you will get how much the skirt cost after the discount.
48.00-7.20=40,80
