The given 8 rolls will have a length of 144 feet or in other words, they will be 144 feet long.
Here, we are given that thee are 8 rolls of carpet and each roll is 6 yards long.
We know that the conversion factor of yards to feet is as follows-
1 yard = 3 feet
Thus, 6 yards = (6 × 3) feet
= 18 feet
⇒ each roll of carpet is 18 feet long
Since there are a total of 8 carpets given, the length of all the 8 rolls will be given as follows-
18 × 8
= 144
Thus, we find that the given 8 rolls will have a length of 144 feet or they will be 144 feet long.

Answer:
-185.75297
Step-by-step explanation:
Solution:-
- We are testing whether the population mean u is equal to 100 as per claim.
Null hypothesis: u = 100
- Where a alternate hypothesis suggest that the population mean ( u ) may be lower:
Alternate hypothesis: u < 100
- We are given sample data parameters which are assumed to be normally distributed:
sample mean, x_bar = 9
sample standard deviation, s = 2.4
- A sample of n = 24 observation was taken from a population of ( N ) with unknown population standard deviation ( σ ).
- The conditions of standard normal distribution are no longer applicable i.e:
n = 24 < 30
unknown population standard deviation ( σ )
- We will model the sample using t-distribution with ( n - 1 ) = 23 degrees of freedom.
- The t-statistics of the sample mean x_bar can be determined from standard t-distribution:
- The t-test value for mean ( u ) is -185.75297

Hope this helps/is correct.
Please don't be mad if it's wrong, this is simply what I understood from the instructions. :)
PS. You don't have to copy the line, that's just for you to get an idea.
To find the answer you first have to turn 4 1/2 a mixed number into an improper fraction. To do this you must multiply the denominator with the whole number to get 8 after add 1 to get 9. to finish off the improper fraction put the 9 as the numerator and keep the denominator of 2. After this you will have 9/2 ÷ 3/4. Remember Keep Change Flip. this means keep 9/2 change the sign from division to multiplication and flip 3/4 to 4/3. After this you will have 9/2 x 3/4. Now multiply the numerators and multiply the denominators. 9x4 is 36 and 2x3 is 6 you now have 36/6. Lucky for you 36 goes into 6, 6 times. So the answer is 6. If you have anymore questions please dont hesitate to ask :) Hope this helps.
