Answer:

Step-by-step explanation:
Given:
Simplify The given choice.




Therefore, the first option
is correct.
1.65 + 0.85x= $20
0.85x=$18.35
x=21 10/17
first you write the equation
then you have to subtract 1.65 from the equation but you also have to subtract it from 20
then you divide 0.85 from 0.85x and from the 18.35 left over from subtracting 1.65 from 20
then you should get x=21 10/17 (simplified) but the decimal form is a ongoing fraction so you can just round it up to the nearest hundredth
Answer: 13/30
Step-by-step explanation:
8/15 -1/10 = (2×8)/(2×15) - (3×1)/(3×10) = 16/30 - 3/30 = (16-3)/30 = 13/30
Answer:
0.6765 = 67.65%
Step-by-step explanation:
This situation can be treated as a binomial model with probability of success (dented can) of p = 0.05.
In 22 random trials, the probability of at least one success is determined by:

The probability that Karen has bought at least one dented can is 0.6765 or 67.65%.
Answer:
Year - (1993 - 1995)
Step-by-step explanation:
Rate of change in the number of toys sold = 
In the interval (1990 - 1993),
Rate of change in number of toys sold = 
= 
= 4000
In the interval (1993 - 1995),
Rate of change = 
= 
= 5000
In the interval (2000 - 1995),
Rate of change = 
= 
= 3000
In the interval (2006 - 2000),
Rate of change = 
= 
= 1000
Therefore, rate of change in the number of toys sold is greatest in the interval (1993 - 1995).
