Answer:
1 and 111 only
Step-by-step explanation:
The goodness of fit test is used to examine if there is significant evidence to say thatvthe observed and expected freqencies are from the desired distribution.
Condituis required for performing a goodness of fit test on a data include :
Randomness, sampled Data must have been chosen at random in other to be representative, here, randomness isn't exhibited as Pasquale used more of convenient sampling questioning the first 40 students.
Also, the expected value of the number of sample observation in each level of the variable should be atleast 5.
This is also violated, as the expected values for some of the levels are less than 5
Hence, conditions 1 and 111 are not met
In order to figure this out, we can set up a proportion and simplify using cross multiplication.

Answer:
14 km
Step-by-step explanation:
<u>1) look at the information you are given:</u>
140 km total (<em>to and from work</em>)
Note that this number includes both the distance to work and the distance from work.
He works 5 days a week.
<u>2)Figure out the distance he travels within one day</u>
This means that you should take the 140 km and divide it by 5 in order to find out the amount of km he travels each day.
<h2>
140 km / 5 days = 28 km</h2>
28 km is the amount of KM he travels each DAY.
<u>3) Figure out the distance from work to home </u>
From this point, it is important to note the question is asking for <u>the distance his work is from home.</u>
Each day, he must travel 2 times: he must go to work and go from work to home, which are both the same distance.
This means that in order to get only the distance from work to home, you must divide by 2.
<h2>
28 km / 2 = 14 km</h2>
- 2 /15 - ( - 9/10 )
-2/15 + 9/10 multiply fraction #1 by 2 an fraction #2 by 3 to get
-4 /30 +27/ 30 = 23/30
