Answer:
no solution
Step-by-step explanation:
The equations are inconsistent. The set of equations reduces to ...
x + 2y + 3z = 12
x + 2y + 3z = 30
x + 2y + 3z = 60
No values of x, y, and z can satisfy all three equations. There is no solution.
No picture of the question? Well if your asking me than it will be 554 and then plus 100 equals 654
Let Zia's age be = x years
Raj is three years older than Zia, so Raj's age = x+3 years
As the sum of the squares of their ages is 369, so
Factoring 2 out we have,
Now solving this equation,
x=-15 and x=12
Neglect the negative value as x cannot be negative
So x=12
Hence, Zia's age is 12 years and
Raj's age is 12+3 = 15 years
Answer:
B, Josef is confused about the range and the interquartile range.
Step-by-step explanation:
You have to make the box plot using the numbers given
Find the IQR *interquartile range* and the difference between the max and the minimum numbers.
For the cars the IQR is: 6
The range for the cars is: 12
The IQR of the minivan is: 3
The range of the minivan is: 12
The ranges are the same but IQR of the cars is bigger, that's where Josef got confused.
