Answer: 30%

Step-by-step explanation:

Calculate the difference between the original price and the discounted price.

21.50 - 15.05 = 6.45

Now, divide the amount saved by the original cost.

6.45/21.50 =.3

Then, multiply the result by 100

.3 * 100 = 30

Answer:

30% percent

Step-by-step explanation:

21.50-15.05=6.45

21.50÷6.45=3.

3×100=30%

We multiply by 100 because 1 is equivalent to 100%. You simply need to multiply the figure by 100 and append the % symbol at the end.

PLEASE HELP! By visual inspection, determine the best-fitting regression model for the data plot below.
Svet_ta [12734]
The initial step is to analyze the graph's behavior.
 It doesn’t follow a linear pattern, as the rate of change is inconsistent.
 It also isn’t exponential since the change rate doesn't fluctuate significantly.
 For this scenario, the most suitable regression model would be of the type:
 y = ax ^ 2 + bx + c

 Where,
 a <0: This indicates that the parabola opens downwards.
 Hence, the most appropriate regression model is quadratic.
 Answer:
 
From visual analysis, the most fitting regression model for the data observed is:

tester [12383]
Only numbers that are composite factors and that, when increased by 1, divide evenly into 48 will work. Thus 15 is suitable. Fifteen is composite, and adding 1 to it gives a number that divides 48. Therefore the son is 15.
