(1) If the regression line equation of y on x is : û : = 0.2x + 3, the value
ofy from the table when x=5 is 4.6, then the value of the error in the
value of y is ...
a 0.6
b 0.4 C 0.3
d 0.1

0.6

Step-by-step explanation:

Given the regression equation :

y = 0.2x + 3,

The actual value of y when x = 5 is 4.6

The predicted of y using the model when x = 5 is :

Put x = 5 in the equation :

y = 0.2(5) + 3

y = 1 + 3

y = 4

The error in the value of y predicted is :

Error = Actual value - Predicted value

Error = 4.6 - 4

Error = 0.6

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
