The calories in a cup of low fat milk is 102 calories and the calories in a cup of milk in skim 86 calories .
<h3>What are the two simultaneous equations that can be sued to represent this question?</h3>
2/3l + 1/2s = 111
4l + 3s = 666 equation 1
l + s = 188 equation 2
Where:
l = calories in the low fat milk
s = calories in the skim milk
<h3>What is the calories in the skim milk?</h3>
Multiply equation 2 by 4
4l + 4s = 752 equation 3
Subtract equation 1 from 3
s = 86
<h3>What is the calories in the low fat milk?</h3>
Substitute for s in equation 2
l + 86 = 188
l = 188 - 86
l = 102

Answer:
True, the scores are not valid.
Step-by-step explanation:
The test supposed to be measuring intelligence. We can assume that the intelligence of most people relatively stable (will not change too much over a short amount of time), and can expect it should go upward with brain growth and education. But the test seems to give a huge decrease from the first and second results. Then the third result is a huge increase that even higher than the first test.
We don't know the true value of the subject, but seeing the huge gap for every repetition we can tell that the test result lacks precision.
