160,000 - 40,000= 120,000/4 = 3 sets of new tires in the first year and 4 every consecutive year.
Given that the<span> iq scores for large populations are centered at 100.
To get what percent of these 78 students have scores above 100 we conduct a normal distribution probability of the data.
P(x > 100) = P(z > (100 - 100)/sd) = P(z > 0) = 1 - P(z < 0) = 1 - 0.5 = 0.5 = 50%

Answer: $80,000
Step-by-step explanation:
40%___$32,000
100%___X=$80,000
(100*32,000)/40 = 80,000
Answer:
21/20
Step-by-step explanation:
a) One hour is equivalent to 60 minutes.
So we can multiply 50 minutes by the fraction 
, so we could convert 50 minutes to hours.
It is:
If we simplify the fraction, we have:
b) In order to express the turtle's speed in miles per hour, we have to divide
by 
So:
We simplify the expression by multiplying 7 mile by 6 and 8 by 5 hours:
