STALIN [3.7K]3 years ago

Answer:

The numbers are 165 and 113

Step-by-step explanation:

Let

x ----> one number

y ----> the other number

we know that

x+y=278 ----> equation A

x=y+52 ----> equation B

substitute equation B in equation A

(y+52)+y=278

solve for y

2y=278-52

2y=226

y=113

<em>Find the value of x</em>

x=y+52

x=113+52=165

therefore

The numbers are 165 and 113

[Systems of equations] (/20) 1. Suppose the coefficient matrix of a system of linear equations has a pivot position in every row
Marina86 [1]

Answer:

The system is consistent because the rightmost column of the augmented matrix is not a pivot column.

Step-by-step explanation:

It is given that the coefficient of the matrix of a linear equation has a pivot position in every row.

It is provided by the Existence and Uniqueness theorem that linear system is said to be consistent when only  the column in the rightmost of the matrix which is augmented is not a pivot column.

When the linear system is considered consistent, then every solution set consists of either unique solution where there will be no any variables which are free or infinitely many solutions, when there is at least one free variable. This explains why the system is consistent.

For any m x n augmented matrix of any system, if its co-efficient matrix has a pivot position in every row, then there will never be a row of the form [0 .... 0 b].

For a data set of thw pulse rates of adult females, the lowest pulse rate is 36 beats per minute, the mean of the listed pulse r
Nadusha1986 [10]

Answer:

The difference between the pulse rate of 36 beats per minute and the mean pulse rate for females is 42 beats per minute.

Step-by-step explanation:

We are given that for a data set of the pulse rates of adult females, the lowest pulse rate is 36 beats per minute, the mean of the listed pulse rate is x = 78.0 beats per minute, and their standard deviation is s = 13.7 beats per minute.

The mean pulse rate for females = \bar x = 78.0 beats per minute

The standard deviation of the listed pulse rate = s = 13.7 beats per minute

The given pulse rate is = 36 beats per minute

So, the difference between the pulse rate of 36 beats per minute and the mean pulse rate for females is given by;

              = \bar x - 36

              = 78 - 36 = 42 beats per minute

Hence, the required difference is 42 beats per minute.
