Answer:
x=9
y=2
z=1
Step-by-step explanation:
xx+yy=zyz
xx can be divided by 11
yy can be divided by 11
zyz can be divided by 11
3 digit multiples of 11
110
121
132...
121=zyz because z=1 and y=2
121-22=99
xx=99
x=9
z=1
y=2
1.082 x 10^8 since the first value must be between 1 and 10
Answer:
no solutions
Step-by-step explanation:
|x+26| = -5
This has no solutions
Absolute value means positive and so the left side must be zero or greater
The right side is negative
This is never true, so there are no solutions
First you need to change the fractions to have the same denominator.
9 1/2 = 9 2/4 + 7 3/4
Then you just add across and simplify.
9 2/4 + 7 3/4 = 16 5/4 = 17 1/4.
You should get 17 1/4. Good luck!
Answer:
B. NON-REPRESENTATIVE
Step-by-step explanation:
<em>The sample does not represent the population as a researcher is taking a sample from the hospital where the cholesterol level of the patient is generally high and the researcher is not randomly selecting the U.S. citizens.</em>
Thus, option (B) is correct.
Further, the sample is a subset of the population and it is easy to analyze as compared to the population.
The sample is said to be representative if it represents the whole population.
