<span>σ</span> is a symbol for summation that means that it is used to add all the vales of the equation in the range
for example taking 0<x<4 and x is an integer
so Ď(x - 2)^2= (1-2)^2+(2-2)^2+(3-2)^2
The options were
a. Square each value
b. Subtract 2 points from each score
C. Sum the squared values
d. Subtract 22 from each X2 value
As we can see above the answer is C. Sum the squared values
The independent variable is always on the x axis (bottom line) and the dependent variable is always on the side (left)
Answer:
<em>v = 3.75 mph</em>
Step-by-step explanation:
<u>Constant speed motion
</u>
An object travels at a constant speed if the ratio of the distance traveled by the time taken is constant.
Expressed in a simple equation, we have:
Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
Sam walks from home to school for a distance of d=0.75 miles in t=12 minutes. To calculate the speed, we need to convert the time to hours.
t=12/60 = 0.2 hours. Now compute the speed:
v = 3.75 mph
Answer:
3/500
Step-by-step explanation:
3/5 x 1%
=> 3/5 x 1/100
=> 3/500

Answer: Second row
The y intercept is 2
=============================================================
Explanation:
The y intercept <u>always</u> occurs when x = 0. Visually, the y intercept is the location where the graph crosses the y axis.
In the table, we see that x = 0 pairs up with y = f(x) = 2 in the second row. So we can say that the y intercept is 2.
Side note: the x intercept is 1 since it occurs when y = 0.
