True
Unbalanced forces are not equal, and they always cause the motion of an object to change the speed and/or direction that it is moving. When two unbalanced forces are exerted in opposite directions, their combined force is equal to the difference between the two forces.
To find a percentage of a number, multiply by the decimal form of that percentage(20%=0.20). So, take the cost, $430, and multiply by common state sales tax (7% for me)---430 x 0.07 = 30.10 The sale tax rate is 7%.
Answer:
15:2 or 15 to 2
Step-by-step explanation:
They are asking for a ratio based on how many chaperones per student (in this case 15 students) In other words 15 students for every 2 chaperones.
The radius on the plan is 6 feet, hence the diameter will be
diameter on plan = 6*2 = 12 feet
<h3>
Mensuration of Flat Shapes(circle)</h3>
Given Data
First pool
Radius of pool on Plan/Blue Print = 5 inches
actual Radius = 20 feet
Second pool
Radius of pool on Plan/Blue Print = ???
actual Radius = 24 feet
From the first pool, we can see that the Proposed Radius is 4 time the Planned radius
Hence, for the second pool let us apply similar logic
Actual radius = 4*x
24 = 4x
divide both sides by 4
x = 24/4
x = 6 feet
Diameter = 6*2 = 12 feet

ANSWER:
I believe you wish to calculate the sum of squares total (SST) for this regression analysis. The sum of squares total is 1053.15
Step-by-step explanation:
The sum of squares total is numerically derived by adding the sum of squares regression (regression sum of squares) to the sum of squares error (error sum of squares). The regression sum of squares here is 752.25 and the error sum of squares is 300.9
This gives us a total sum of squares of 1053.15
Sums of squares tell if a linear regression of one variable (or variables) on another is good or not.
The squared differences between the observed dependent variable and its mean is a measure of the total variability of the data set.
So the SST is equal to 752.25 + 300.9 = 1053.15
