Answer:
The expression to the statement in roaster form is:
{1,2,3,4,5,6}
Step-by-step explanation:
<em>" To express the set in roster form the elements of a set are listed within the curly brackets and are separated by commas " .</em>
We are given a statement as:
" The set of natural numbers less than 7" is represented in roaster form as:
{1,2,3,4,5,6}
( since, the natural numbers are the positive integers (whole numbers) 1, 2, 3, etc. and we asked to find the numbers less than 7).

Answer with explanation:</u></h2>
Let
be the population mean.
Null hypothesis : 
Alternative hypothesis : 
Since Alternative hypothesis is left tailed so , the test is a left tailed test.
Given : n=33 > 30 , so we use z-test.
Test statistic : 
i.e. 
Using z-value table,
P-value for left tailed test =
Since , the p-value (0.0020524) is less than the 0.05 level of significance, it means we reject the null hypothesis.
Therefore, we have enough evidence to support the claim that the mean completion time has decreased under new management.
The answer would be A. The triangle with the 70 seems to be isosceles and that means that two of the angles equal 70. 70+70=140. Subtract 140 from 180 to find the third angle because every triangle has a total of 180 degrees. Due to the fact that x and the 40 degrees are on the same line, they will equal 180 degrees. So, 180-40=140. X=140. I hope this helps
If they combined the tow batches they would equal 5750ml and they would have 31 servings of punch with 180 ml per serving. But they would be left with 94ml
Answer:
Step-by-step explanation:
4.625%- percents and decimals are the same
four and five eighths- five divided by eight is (.625) and 4+ (.625) is 4.625
thirty seven eighths- 37 divided by 8 is 4.625
