20/100 = x/12
The 20/100 in the expression represents the 20%. The x in this scenario is the unknown amount in which the person will tip. The /12 is the cost of the original price. So, in order to find the value of x, you would need to cross multiply.
x = $2.40
The total cost would be $2.40 + $12.00 = $14.40
The answer should be 7x10^7
3) This is definitely a positive association, but the question is - is it linear?
Since a somewhat straight line can be drawn through the points, it is linear.
<span>
Answer: positive linear association </span>
4) Find the slope using the formula
m = 43 - 48/ 4 - 2 = -5/2 = -2.5
Negative association, but is it linear? Lets find out
Oh no! It seems that their is not a pattern in the association, so its nonlinear!
Answer: Negative nonlinear association5) <span>
m = 80 - 66/ 5 - 3
m = 14/2
m = 7
Positive! But is it linear??
Let us draw a graph this time.
I know my graph is messy, but can you see the nonlinear-ness? It doesnt form a straight line!
Answer: Positive nonlinear association </span><span>Hope this helped. :) </span>
You're basically doing 890 divided by 1, so the answer would be 800.. 800 ones.
Answer:
Step-by-step explanation:
We need to find the solution to the following equation: . Given that the the natural logarithm is the inverse function of the exponential, we have that: .
Applying this rule:
⇒
Solving for 'x':
⇒
