If <span>∆QRS≅∆TUV, Their corresponding sides would be equal so,
QS = TV
4v + 3 = 7v - 9
7v - 4v = 3 + 9
3v = 12
v = 4
Now, QS = TV = 4(4) + 3 = 16 + 3 = 19
In short, Your Answer would be Option C
Hope this helps!</span>
Mean = Numbers added up and divided by the amount of numbers.
Mean = 45 + 90 + 18 + 53 + 13 + 38 + 22 + 59 + 49
Mean = 387 ÷ 9
Mean = 43
Median = The middle number when arranged in order
Median = 13, 18, 22, 38, 45, 49, 53, 59, 90
Median = 45
Mode = The number that occurs most often
Mode = There is no mode because each number occurs the same amount of times
Range = Biggest number takeaway smallest number
Range = 90 - 13
Range = 77
Answer: 20%
Step-by-step explanation:
Profit of $4,000 is divided by the cost price of $20,000:

Step-by-step explanation:
−2.4n − 3 + (−7.8n + 2) =
= -2.4n - 7.8n - 3 + 2
= -10.2n - 1
Answer:
a relationship ( model equation)
Step-by-step explanation:
the relationship specifies how the dependent variable relies on the independent variable.This helps in manipulating of the variable to see its effect/outcome.The relationship can be mathematical or logical ; it can also be a set of algorithm (program) which can be worked on using the independent variables as inputs. Usually the independent variables influence the dependent variables.
