Answer:
61.512
Step-by-step explanation:
Put 14 where x is and do the arithmetic. Arguments for trig functions are always radians unless otherwise specified.
y =18.614 sin(0.521x - 1.984) + 76.900
y =18.614 sin(0.521·14 - 1.984) + 76.900 = 18.614sin(5.31) +76.900
y ≈ 18.614·(-0.82668) +76.900 = -15.388 +76.900
y ≈ 61.512
The regression model predicts y(14) = 61.512.
Answer:
Correct option is : 1) It has a slope of 7 and a y-intercept of -2.
Step-by-step explanation:
The given function is :
.....1
The general form of equation of a linear function is given by :
.....2
where, y is the dependent variable, x is the independent variable, m is the slope of the function and c is the y-intercept.
On comparing equations 1 and 2, we get:
m = 7,c = -2
Thus, we can conclude that : Slope of equation is 7 and y-intercept is -2.
Thus, only option 1 satisfies the given solution.
