Answer:
. A LINEAR REGRESSION is your answer
Drey makes $10 an hour plus $15 an hour for every hour of overtime. Overtime hours are any hours more than 40 hours for the week.
Part A: Create an equation that shows the amount of wages earned, W, for working x hours in a week when there is no overtime.
If there is no overtime, the equation is W = 10x.
Part B: Create an equation that shows the amount of wages earned, S, for working y hours of overtime. Hint: Remember to include in the equation the amount earned from working 40 hours.
At $10 per hour for 40 hours, the total is $400.
S = 15y + 400
Part C: Drey earned $490 in 1 week. How many hours (regular plus overtime) did he work?
490 = 15y + 400
490 - 400 = 15y
90 = 15y
90/15 = y
6 = y
Drey worked 46 hours in all.
Answer:
Step-by-step explanation:
The first term is simply a(1), and is 5.
The fourth term is a(4), and is 5 + (1/6)(4-1), or 5 3/6 or 5 1/2.
The tenth term is a(10), and is 5 + (1/6)(10 - 1), or 5 + 3/2, or 6 1/2.
93.5 + 8.7 = 102.2
Hope this helps! :)
Answer:
The velocity of jet in still air is 
and velocity of wind is
.
Step-by-step explanation:
Let x be the rate of the jet in still air and y be the rate of the wind.
Given:
Velocity against wind, a jet travels 2160 miles in 3 hours.
Velocity against wind 
Flying with the wind, same jet travels 6000 miles in 6 hours.
Flying with the wind 
As such its velocity against wind is 
and with wind is
therefore
------------(1)
---------------(2)
Adding equation 1 and 2.
Put x value in equation 2
Hence velocity of jet in still air is and velocity of wind is
.
