Answer: (D) The external validity of the study
Explanation:
The external validity is the type of study which basically depicts that the concept of the study result must be meaningful. The external validity mainly apply in the conclusion in the scientific concepts and study about the main context.
External validity is the type of validity in which we extent the result of the study across the different types of situations, times and people. In mathematics, the external validity concept is applicable for determining the statistical and the various computational methods.
There are three steps
1 rearrange the equation so "y" is on the left and everything else is on the right
2 plot the "y=" line (make it a solid line for y< or y> and a dashed line for y< or y>)
3 shade above the line for a "greater than" (y> or y>) line under that or below the line for a less than (y< or y< line under it)
Answer:
the answer is 180 dollars
Step-by-step explanation:
20 is 10% of 200 so just subtract that
Answer:
D
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = ( - 
, 
) and r = 
, thus
(x - (- ))² + (y - )² = ( )², that is
(x + )² + (y - )² = 
→ D
If there are 4 trucks then the first truck weighs x
then x+2tons
then x+4tons
then x+6tons = 32tons
so 4x+12=32
-12 -12
/4 /4
x=5
so plug it back in
truck 1= 5tons or 10,000lbs
truck 2= 7tons or 14,000lbs
truck 3= 9tons or 18,000lbs
<span>truck 4= 11tons or 22,000lbs</span>
