Step-by-step explanation:
<u>Question 2. 25% of what number is 30?</u>
25% - Whole 30, 50% Whole 60, 75% Whole 90, 100% Whole 120
<u>Question 3. What operation did you use the find the whole?</u>
In the previous question, I found the whole, adding 30 to the previous value.
For example, I added 30 to 30 and calculate 60. To 60 then i added 30 to get 90 and added 30 to get 120 because in this question, all the 4 parts were exactly the same size (30).
<u>Question 4. What are you multiplying/dividing? Do you use the percent or something else?</u>
In the specific case of question 2, I noticed that the size of the parts were exactly the same, using it for calculating the whole. If 1 part out of 4 is 30, then 2 parts or 50% are 60, 3 parts or 75% are 90 and then 4 parts of 100% are the whole I'm being asked, in this case, 120.
Answer:
E(X ¯)=210,000.
Step-by-step explanation:
A sampling distribution for samples of size n=49 from a population with means μ=210,000 and standard deviation σ=35,000, has the following means anda standard deviation:
If X ¯ is the mean sales price of the sample, it will have a mean value of E(X ¯)=210,000.
Answer:
$108
Step-by-step explanation:
Number of Cartons of Ice Cream=19
Cost Per Carton of Ice Cream=$6
Total Ice Cream Cost = $6 X 19 =$114
Number of Cartons of Yoghurt=3
Cost Per Carton of Yoghurt=$2
Total Yoghurt Cost = $3 X 2 =$6
The difference in cost=Total Ice Cream Cost-Total Yoghurt Cost
=114-6
=$108
Brenda spent $108 more on ice cream than on yogurt
<u>Answer</u>
18) $51
19) $24
20) <em> Carla's account. </em>
<u>Explanation</u>
18)
Positive sign values means deposit while the negative values means money been withdrawn from the account.
$100 - $18 + $22 - $53 = $51
19)
Positive sign values means money deposited while the negative values means money been withdrawn from the account.
$45 - $17 - $22 + $18 = $24
20)
To get the person with the most deduction, you should add the negative values in the table then compare.
Carla ⇒ -18 + -53 = $-71
Leta ⇒ -17+ -22 = $-39
From here we can see that the account with greatest decrease is<em> Carla's account. </em>
