Answer:
0816.166 recurring.
Step-by-step explanation:
6 times table : 6, 12, 18, 24, 30, 36, 42, 48.
6 ÷ 4= 0 so 6 didnt go into 4 leaving it to be a remainder so you carry the number over.
how many times does 6 go into 48, which is 8 times.
so far, this is what it would look like.
6 goes into 9, 1 leaving a remainder of 3,so we carry it over to the next number.
how many times does 6 goes into 37, which is 6 times leaving a remainder of 1.
Now we need to go into the decimals because we still have a remainder.
so we now have 10, 6 goes into 10, 1 remainder 4.
how many times 6 goes into 40, 6, remainder 2.
6 goes into 20, 3 times remainder 4. this is going to end up recurring because we ended up with the same number so your full answer, putting all the numbers together would be
0816.166 recurring.
Answer:
a) It is expected to sell 560 cars.
b) The total amount invested is $145,000.
c)
m is the slope of the linear function, and represents <em>the additional amount of cars it will sell due to an additional dollar invested in advertising</em>. Its units of m is [cars/dollar].
b is the y-intercept and represent t<em>he amount of cars the company would sell if there is 0 dollars invested in advertising</em>. It may or not be a representative point in the real world (it depends on how accurate is the linear function and the range where it is valid). The unit of b is [cars].
Step-by-step explanation:
a) If the company invest $90,000, that is 3 times $10,000 plus the originals $60,000. Then, it is expected to sell 560 cars.
b) If the company sold 800 cars, we have 440 cars that corresponds to the original $60,000 and (800-440)=360 cars that correspond to the additional invest.
If an additional 40 cars are sold by an additional $10,000 invest, 340 cars are sold by 340*10,000/40= $85,000.
Then the total amount invested is 60,000+85,000=$145,000.
c) We can estimate the parameters m and b of the equation taking into account one known point ($60,000 corresponds to 440 sold cars) and the known variation (40 sold cars for every $10,000 invested).
Then we can use the known point to estimate b:
The equation is then
m is the slope of the linear function, and represents <em>the additional amount of cars it will sell due to an additional dollar invested in advertising</em>. Its units of m is [cars/dollar].
b is the y-intercept and represent t<em>he amount of cars the company would sell if there is 0 dollars invested in advertising</em>. It may or not be a representative point in the real world (it depends on how accurate is the linear function and the range where it is valid). The unit of b is [cars].
