Answer:

Step-by-step explanation:

Hint:  1- 2sin²x = Cos 2x

LHS = 1 - 2Sin² (π/4 - Ф/2)

        =  Cos 2 *(π/4 - Ф/2)

        = Cos 2*π/4 - 2*Ф/2

         = Cos π/2 - Ф

         = Sin Ф =  RHS

Answer:

RHS=sinA

Step-by-step explanation:

LHS=1-2sin^2(45-A/2)

=cos2(45-A/2)

=cos(90-A)

=sinA proved.

If a line cuts the y-axis at y=-6 and the slope of the line is -10, find the equation of the line.​
sweet-ann [11.9K]

Answer:

y = - 10x - 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 10 and c = - 6, thus

y = - 10x - 6 ← equation of line

In the simple linear regression model estimate Y = b0 + b1X
Sav [38]

Answer:

Option B) Y - estimated average predicted value, X – predictor, Y-intercept (b_0), slope (b_1)    

Step-by-step explanation:

In the simple linear regression model estimate is given by:

Y = b_0 + b_1X

Comparing this regression line with the slope intercept form, we get:

y = mx + c

where m is the slope of the straight line and c is the y-intercept that is the value of y when x is zero.

here,

Y is the predicted variable or the variable we need to predict

X is the predictor or the variable that helps us to predict Y

b_1 is the slope of the regression line.

b_0 is the y-intercept or the value of y when x is zero.

Thus, Option B)

Y - estimated average predicted value, X – predictor, Y-intercept (b_0), slope (b_1)
