1/7-9/7n+6/7
1-9/7n
that is the extended form and is simplified
Hope it help! :)
Answer:
1.66
Step-by-step explanation:
We need to conduct a chi square test
The statistic used to check this is given by the below
∑(n, 1) = [(O(i) - E(i)] / E(i)
From the question, we're told the observed value is
Freshmen
Sophomore
Junior
Senior.
After that, we then calculate the expected value.
Freshman
0.3 * 300 = $90
Sophomore
0.24 * 300 = $72
Statistics then finally gives us this
X² = (93 - 90²)/90 + (68 - 72)²/72 + (85 - 78)/78 + (64 -60)²/60
X² = 3² / 90 + 4² / 73 + 13² / 78 + 4² / 60
X² = 0.1 + 0.212 + 2.167 + 0.266 x+
X² = 2.745
X = √2.745
X = 1.66
If im correct it would be -2(2)+4(-2)-5 which is -4-8-5 which would be -17
The running total is $95.27.
There are two types of records, Active and Inactive. There are also two major classifications, Vital and Important.
<h3>Why is record keeping important?</h3>
- In order to create reliable financial statements, you need good records. These consist of balance sheets and income (profit and loss) statements. These statements might assist you in managing your business and dealing with your bank or creditors.
He opened the account with $299.88. He subsequently wrote many cheques, from which you deduct the sum of 299,88.
He deposited a check, thus 299.88-90.48= 209.40, 209.40 - 65.00= 144.40, and then he added $381.33 to 144.40 to get 525.73.
then you need to deduct more since he wrote more checks.
Consequently, 525.73-54.47=471.26, and 471.26-375.99=95.27, giving him a balance of $95.27.
- Good Records entail documents comprising recorded data that show the efficacy of the quality management system, independent of the format or feature.
