Answer:
The cost of 43 mile taxi ride is $ 30.1
Step-by-step explanation:
Given as :
The distance travel is 54 mile
The time of travelling is 63 min
The cost of traveling is $37.80
Now
∵ For travelling 54 mile , the cost of traveling = $37.80
∴ For travelling 43 mile , the cost of traveling = 
× 43
Or, For travelling 43 mile , the cost of traveling = 0.7 × 43
Or, For travelling 43 mile , the cost of traveling = $ 30.1
Hence, The cost of 43 mile taxi ride is $ 30.1 Answer

Answer: $49,875; $4,830C.
Step-by-step explanation:
The average salary of Teachers in a medium-sized suburban school district is $47,500 per year.
The standard deviation is $4,600
After negotiating with the school district, teachers recieve a 5% raise and a one-time $500 bonus. The bonus of $500 will not alter the mean and standard deviation because equal amount is added for each teacher.
5% increase in each teacher's salary would differ. Therefore, it will affect the mean and standard deviation by 5%. Therefore, the new mean would be
47500 + (5/100 × 47500) = $49875
The new standard deviation would be
4600 + (5/100 × 4600) = $4830
Answer:
Read the chapter and concepts First
To apply the quadratic formula, the right side must be equal to 0.
Now you can apply the quadratic formula
to find the solution for w.
(The quadratic formula is highly unnecessary in this problem, however. You could easily divide all values by 2 to get w²-14w+49=0, which factors into (w-7)²=0, for which 7 is the only solution which puts a factor of the quadratic equal to 0.)
