I don’t really get what you’re asking here but a system of 2 parallel lines has no solution, and a system of 2 parallel lines is called inconsistent.
Answer:
30%
Step-by-step explanation:
Before starting to solve this question we have to understand the following. 1% is equal to one hundredth of something whole, and can be write as 
.
Now in order to solve this question we will first have to find a fraction that represent how much student out of the whole class choose hamburgers. We can easily find this fraction since the numerator of the fraction will be equal to the number of people that choose hamburgers and the denominator will be equal to the number of all students in the class. So we get......
Now in order to find out what percentage will this fraction equal to we will have make a fraction with the same value but with a denominator being 100. To do that we will have to understand the following......
(m is any number except 0)
The main I idea of this rule is that if we multiply the numerator and the denominator by the same number (any number except 0) we will get a fraction with the same value but with a different denominator and numerator.
So in our case we we do the following.........
(multiply both numerator and the denominator by 10 and we get...)
Now if we go back to what I said at the start of my explanation we will understand that another way of writing down 
is 30%.
Answer:
Measurement error.
Step-by-step explanation:
Measurement Error are the error when there is difference found in true value of data and measured quantity of data. This difference could be found if we are missing some data in the sample.
The error could be reduced by carefully designing the process of data collection and it´s measurement.
Measurement error are classified into two type of error:
- Random error.
- Systematic error.
There are two choices for each child: overweight (o) or underweight (u). So if the first child is o the next can be o or u. If the first is u the second can be o or u. This gives four possibilities. Here the first child is the letter noted first and the second is the one listed second:
OO
OU
UO
UU
There are 4 outcomes and if each is equally likely then the probability of each is 1/4. Thus the probability of UU is 1/4
The probability of one underweight and one over weight is 1/2 because in two of the outcomes listed above there is one O and one U (namely OU and UO). Since there are 4 outcomes the probability is 2/4 = 1/2
Answer:
Look to the explanation
Step-by-step explanation:
* Lets arrange the steps for bisecting angle ABC
- The vertex of angle ABC is B, and its rays are BA and BC
# Step 1:
- Place the compass on point B, and swing an arc that intersects rays
BA and BC ⇒ 5th
# Step 2:
- Place point D on the intersection of the arc on ray BA and point E on
the intersection of the arc with ray BC ⇒ 3rd
# Step 3:
- Place the compass on point D, and draw an arc inside the angle ⇒ 6th
# Step 4:
- Keeping the compass the same distance, place the compass on
point E, and draw an arc inside the angle ⇒ 2nd
# Step 5:
- Place point F on the intersection of the arcs created from points D
and E ⇒ 4th
# Step 6:
- Draw a ray from point B through point F ⇒ 1st
* This ray is the bisector of the angle ABC
