Answer:
35 minutes
Step-by-step explanation:
Divide 700 by 20.
Something is missing in right hand side
Ten (10) more than (+) half (
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
) of a number (x) is (=) eight (8) less than (-) twice (2 x ) the number (x).
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D)
x + 10 = 2x - 8 Multiply both sides by 2
x + 20 = 4x - 16 Subtract x from both sides
20 = 3x - 16 Add 16 to both sides
36 = 3x Divide both sides by 3
12 = x
4/8 + 3/8 + 1/8 = 8/8 = 1
They completed the whole project.
Answer:
<em>The sample may be a representative of the future of the future subjects, but the test results and confidence interval are suspect because it is not a random sample </em>
Step-by-step explanation:
When the subjects used for a research are not a random sample but friends whom share similar qualities/quantities related to the purpose of the experiment. The sample may be a representative of the future subjects, but the test results and confidence interval will not be reliable enough to be accepted as standard simply because it was not a random sample
Hence the comment <em>:The sample may be a representative of the future of the future subjects, but the test results and confidence interval are suspect because it is not a random sample </em>
