Answer:

It increases

Step-by-step explanation:

The mean of the given data set of 8 values is 4.75 (\frac{2+4+5+6+8+2+5+6}{8})

Adding 7 into the data set also increase the number of data points to 9, so the mean becomes:\frac{2+4+5+6+8+2+5+6+7}{9}, which is equal to 5

Hope this helps

Evaluate the function for x=4 <br> F(x)= x^3+2x^2+1
alukav5142 [94]

Answer:

F(4) = 97

Step-by-step explanation:

F(x)= x³+2x²+1

when x = 4

F(4)= 4³+2(4²)+1

= 4³+2(4²)+1

= 64 + 2(16) + 1

= 64 + 32 + 1

= 97

What is the quotient of (x cubed 3 x squared minus 4 x minus 12) divided by (x squared 5 x 6)?
liubo4ka [24]

The quotient of x^{3}+3x^{2} -4x-12 divided by x^{2} +5x+6 is (x-2_.

Given the polynomial x^{3}+3x^{2} -4x-12 and x^{2} +5x+6 and the first expression or polynomial is divided by second.

Quotient is a number that is obtained by dividing two numbers. It can be of two numbers or two expressions. Remainder is a number or an expression left after division of two numbers.

To find the quotient of x^{3}+3x^{2} -4x-12 divided by  , we have to divide the expression first.

We know that ,

Divident=Divisor*Quotient+remainder

x^{3}+3x^{2} -4x-12=x^{2} +5x-6*(x-2)-12

If we carefully watch the above equation and compares with the above formula then we can easily find that the value of quotient is (x-2).

Hence the quotient of x^{3}+3x^{2} -4x-12 divided by x^{2} +5x-6 is (x-2).
