0,-1 works . Not sure about the rest- if it’s meaning anything within the shaded area, everything but 3,0 and -3,-2 works.

Suppose C = 20y + 15 and y = 50x + 5. Which of the following is equivalent to C = 20y + 15, but written only in terms of x?
Olegator [25]

Answer:

C = 1000x + 115 (Answer B)

Step-by-step explanation:

We know that..

C = 20y + 15

y = 50x + 5

So put the Y value in the equation of C

C = 20 (50x + 5) + 15

C = 1000x + 100 +15

C = 1000x + 115

A positive binary number is even precisely when its last digit is 0. When is a negative 2's complement number even?
Alex

Answer:

A negative 2’s complement number is even precisely when its last digit is 0 as well.

Step-by-step explanation:

Proof part 1: Assume there exists a 2’s complement negative even number which ends with 1. We  can, therefore, express this number as

1 ..... 1  = - (2’s complement of 1 ....1)

         = - (0 ...  1 )

         ≠ even

Since we know precisely that a positive binary number is not even when it ends with a 1. This is  a conflict with our assumption. Our assumption is, therefore, wrong.

Proof part 2: Assume there exists a 2’s complement negative odd number which ends with 0. We  can, therefore, express this number as

1 ..... 0  = - (2’s complement of 1 ....0)

         = - (0 ...  0 )

         = even

Since we know precisely that a positive binary number is even when it ends with a 0. This is a  conflict with our assumption. Our assumption is, therefore, wrong.

Observed and predicted values of a variable Y based on a sample of size n=9 and a forecasting model are given below. Compute sam
navik [9.2K]

Answer:

\bar{Y} = 17.2667

S_y^2 = 3.8626

MAD = 8.6778

SME = 535.3322

Step-by-step explanation:

The sample mean for a finite set of values is given by:

\bar{Y} = \frac{1}{n} \sum{y_i} = 17.2667

The standard deviation for a finite set of values is given by:

S_y^2 = \frac{1}{n-1} \sum (y_i - \bar{y})^2 = 3.8626

The MAD for a set of predicted values is given by:

MAD = \frac{1}{n}\sum|y_{predicted} - y_{real}| = 8.6778

The MSE for a set of predicted values is given by:

SME = \frac{1}{n}\sum(y_{predicted} - y_{real})^2 = 535.3322
