Yes. 440 times 10 is 4400
Answer: 11
Step-by-step explanation:
Equation for situation:
28 + 4x
Plug in 11 into x (represents week)
28 + 4 (11) = 72 dollars
Answer:
125-135
Step-by-step explanation:
The standard deviation is 7. This implies that the IQ scorings can be between 123 and 137. With a 90% confidence in these numbers, 125-135 is the closest interval to 90% confidence.
The general equation of the circle is:
(x -xo)^2 + (y - yo)^2 = r^2
Where xo,yo are the coordinates of the center and r is the radius of the circle.
Here (xo,yo) is (-16,30) and you can find the radius.
You can find the radius using the equation of the distance (Pythagoras) between the center (-16,30) and any point on the circunference. Here use (0,0)
r^2 = (-16 - 0)^2 + (30 - 0)^2 = 1156
Then, the equation is>
(x - (-16) )^2 + (y - 30)^2 = 1156
=> (x + 16)^2 + (y - 30)^2 = 1156. <----- answer
The diagram shown relates age with mileage, so to get the mileage at any age,
we trace the age in years to the line of best fit and;
trace horizontally to cut the vertical axis and obtain the overall mileage.
Doing this, we get;
We observe that the overall mileage according to the line is;
135,000 Option B
