The line of best fit is a line that follows the direction of the dots. It doesn't have to be perfect, it's just a general line to represent the data. Sometimes there isn't a line of best fit (if there is no correlation). It normally touches most of the dots.
The slope is about 1/2 and the point where the line touches the y axis is at 40 so that means an equation could be y = 1/2x + 40
When the advertising expenditure (x value) is 18,000, substitute it into the equation above. y = 1/2(18,000) + 40 which equals y = 9,040 . This is the expected revenue.
Hope this helps!
I will assume that 0 =72 refers to that the angle of the sectoris 72°.
If so, this sector represents 72°/360° = 1/5 of the total circle.
Then the area of the total circles is 5 * 45yd^2 = 225 yd^2
The radius is obtained from:
Area = π(r^2) = 225 yd^2
r^2 = 225 yd^2 / π = 71.62 yd^2
r = √(71.62yd^2) = 8.5 yd
Answer: 8.5 yd
we are given the following inequality:
To solve for "k" we will divide both sides by -3, since we are dividing by a negative number we will change the direction of the inequality sign, we get:
Solving the operations we get:
Therefore, the solution is the numbers that are smaller than negative 2.
Answer:
B. 7.8 gal
Step-by-step explanation:
x= 250
y= 0.03x + 0.25
y= 0.03(250) + 0.25
y= 7.5 + 0.25
y= 7.75
Since 7 is in the hundredths place you round up and make it 8. leaving you with the answer 7.8
