Delvig [45]2 years ago

Answer:

1/2b - 5 (the third one)

Step-by-step explanation:

"Denni is five years less..."

this tells us we will need to be subtracting five, which knocks out the other answers.

"..one-half his brothers age."

since b represents the age of his brother, one half his brothers age is 1/2b  

That leaves us with 1/2b - 5

Use cramer's rule to determine if the system is inconsistent system or contains dependent equations. 2x + 7 = 8 6x + 3y = 24 que
Natali [406]
Answer: In the equations that you have given, we have a dependent system.

2x + y = 8 (I assumed that you meant to type y instead of 7)
6x + 3y = 24


To use Cramer's Rule, we have to take the determinant of 3 different matrices written in the problem. Taking the determinant of the coefficient matrix produces a zero.

2  1   This is the coefficient matrix.
6  3

6 - 6 = 0

Since this is 0, the rest of the work will be undefined meaning the systems are dependent (or they are the versions of the same equation).

Find the mean absolute deviation
pantera1 [17]
First find the mean (sum divided by number of values)
4+5+8+10+15=42
42/5=8.4
Then find the difference between each of the numbers and the mean.
4.4, 3.4, 0.4, 1.6, 6.6
Then find the mean of those values.
4.4+3.4+0.4+1.6+6.6=16.4
16.4/5=3.28
