By doing so, they provide the illusion that the payments are cheaper then 1000 dollars, because 50 looks very small, when in reality it's $100 more then what the mattress is actually worth.
6.5 is the mean of the data
Answer:
Step-by-step explanation:
To find the hourly rate, we would first need to take the total earnings and subtract the bonus.
$164 - $50 = 114
This gives us the total money earned for hourly work.
Then we need to add the total hours worked: 4 + 8 = 12.
Lastly, we need to take the total money earned and divide it by the total hours worked: 114 / 12 = 9.50 or $9.50 per hour.
The equation could look like:
4h + 8h + $50 = $165
I don’t get what the question?
When a line is perpendicular to another line, the gradient becomes the “negative reciprocal” which basically means flip the gradient and change the sign. In this instance the negative reciprocal of 5x has to be -1/5 as it has been flipped and made negative. At this point the answer can only be B or C.
After this you can use the point given to work out the y-intercept:
y-y1 = m(x-x1)
y-3 = -1/5(x+10)
y-3 = -1/5x - 2
y = -1/5x -1
And there’s your answer: C
