Answer:
P(0) = 2000
P(10) = 2414
Step-by-step explanation:
The price for today is given by P(t) when t=0. Put 0 where t is, and do the arithmetic.
P(0) = 2000·1.019^0 = 2000
The price in 10 years is given by P(t) when t=10. Put 10 where t is, and do the arithmetic.
P(10) = 2000·1.019^10 ≈ 2000·1.207096 ≈ 2414
Options :
(A.) y=558-273x (B.) y=264+142x (C.) y = 55.8 +2.79x (D.) y= -26.4-1.42x
Answer:
C.) ŷ = 2.79X + 55.8
Step-by-step explanation:
Given the data:
cost (x): 9 2 3 4 2 5 9 10
Number of products sold: 85 52 55 68 57 86 83 73
Using the online regression calculator to generate a linear regression plot of the given data: the model obtained is given below
ŷ = 2.79X + 55.8
With y being the predicted or dependent variable
Slope or gradient of the line = 2.79
X = the independent variable
55.8 = the intercept.
Well when x is -1, y = 0, then when x is 0, y = 3 so it is increasing there...then when x is 1, y = 6, so it is still increasing, but then it goes back down to 3 when x is 2
Therefore, the largest interval would be from -1 to positive 1 (-1,1)
Hope this helps

Take an example
14 / 20
the GCF of 14 and 20 = 2 ( 20 = 2^2 * 5 and 14 = 2*7 so 2 is the GCF)
so we can divide top and bottom of the fraction by 2 to give 7/10 = simplest form
