3x^{2} +1=28

Step 1 : subtract 1 from both sides

3x^{2} =27

Step 2 : Divide both sides by 3

\frac{\frac{3x^{2} }{3} }{\frac{27}{3} }

x^{2} = 9

Step 3 : Find the square root of 9

\sqrt{9} = 3

x= (-3,3)

remember negative × negative = positive

ipn [44]

Answer:

Statement D is correct.

Step-by-step explanation:

Solution:

Data Given:

Linear Regression Relationship = Speed = 10.3 + 5.4 (hour)

Linear Regression Relationship = y = mx + c

Here,

m = slope = 5.4

c = 10.3 = y - intercept

The correct Answer is D)

Because:

As, the residual value is positive, it means the typist attained faster speed than the model predicted. As we know, residuals is the result of difference between predicted values of the model and data values. On the contrary, if residual would be negative then we would say that typist speed is slower than the model predicted.

Hence, Statement D is correct.
