Answer:

x = -3n/4

Step-by-step explanation:

in order to solve for x in this expression we would open the bracket with -3 according to BODMAS rule. then we would evaluate for the value of x

-3(x+n) = x what is x

-3x-3n= x

-3x = x + 3n

-3x -x = 3n

-4x = 3n

divide both sides by the coefficient of x which is -4

-4x/-4 = 3n/-4

x = -3n/4

therefore the value of x in the expression -3(x+n) = x is evaluated to be

x = -3n/4

tigry1 [53]

Bezels, gradients, and drop shadows can make an interface user-friendly if used wisely and minimally. If too much, the interface can be distracting. The problem used the term "maximal." This means that the bezels, gradients, and drop shadows are excessively used in an interface. So, the answer to this question is
FALSE

Answer:

Step-by-step explanation:

a)General least square regression line is ,

$Y=a+(b*x)$

Where,a=intercept. b= slope

To get line just find values of a and b.

Use Excel to find values.

First enter values of variable "age" that is y in the column A that is A1to A5 and values of variable "height" in the column B, B1 to B5.

Then for value of a use functufuas ,

=INTERCEPT(A1:A5,B1:B5)

Then hit enter ,therefore a=20.4595

For b use function as. =SLOPE(A1:A5,B1:B5)

Then hit enter.therefore b=0.3738

Therefore equation of least square regression line is

Y=20.4595+(0.3738*x)

b) to predict height at age 21 years or 252 month just put value of x=252 in the above equation.

Y=20.4595+(0.3738+252)

Y=20.4595+94.1976

Y=114.6571

Conclusion: height will be 114.6571 inches when age change by 1 unit.
