place.
Answers
Answer:
680
Step-by-step explanation:
add al you can add all of them and then my total came to 67 7.64 rounded to the nearest should be around 680
The total expenses for the month including electric bills, TV streaming service and rent is $677,6.
What is summation?Summation is basically the result obtained by addition of all the numbers whose summation is to be obtained. The symbol used is ∑ for summation.
How to calculate total expenditure?The expenditures done by Peter who lives in an apartment are:
Electric bill=$34.80
TV streaming service=$27.99
Rent=$614,85
Total expenditure incurred by Peter on electric bill, TV streaming service and rent =34.80+27.99+614.85
=$677.64

Jim sells candy bars to his family and friends as a fundraiser. The plain chocolate bars costs $1.50, and the king size chocolate bar costs $2.25. Jim sells a total of 55 candy bars, and earns a total $95.25. Write a system of equations and find out how many plain chocolate bars he sold, and how many king size bars he sold.
Answers
Answer:
38 plain chocolate bars and 17 king-size chocolate bars.
Step-by-step explanation:
Let's define the variables:
P = number of plain chocolate bars sold
K = number of king chocolate bars sold
We know that each plain one costs $1.50, and each king one costs $2.25, then the total revenue is:
P*$1.50 + K*$2.25
Now we know that Jim sells a total of 55 candy bars, then:
P + K = 55
And we know that the total revenue is $95.25, then:
P*$1.50 + K*$2.25 = $95.25
Then we have the system of equations:
P + K = 55
P*$1.50 + K*$2.25 = $95.25
To solve this we need to isolate one of the variables in one of the equations, I will isolate P in the first equation to get:
P = 55 - K
Now we can replace is on the second one to get:
(55 - K)*$1.50 + K*$2.25 = $95.25
Now we can solve this for K
$82.50 - K*$1.50 + K*$2.25 = $95.25
K*($2.25 - $1.50) = $95.25 - $82.50 = $12.75
K*$0.75 = $12.75
K = $12.75/$0.75 = 17
This means that Jim sold 17 king-size chocolate bars.
Now we can replace this in the equation:
P + K = 55
P + 17 = 55
P = 55 - 17 =38
P = 38
Jim sold 38 plain chocolate bars.

A cohort study was undertaken to examine the association between high lipid level and coronary heart disease. Participants were classified as having either a high lipid level (exposed) or a low or normal lipid level (unexposed). Because age is associated with both lipid level and risk of heart disease, age was considered a potential confounder, and the age of each subject was recorded. The following data describes the study participants:Overall, there were 11,000 young participants and 9,000 old participants. Of the 4,000 young participants with high lipid levels, 20 of them developed CHD. Of the 6,000 old participants with high lipid levels, 200 of them developed CHD. In the unexposed, 18 young and 65 old participants developed CHD.1. Construct the appropriate two by two tables using the data given above. Be sure to label the cells and margins.2. Calculate the appropriate crude ratio measure of association combining the data for young and old individuals.3. Now, perform a stratified analysis and calculate the appropriate stratum-specific ratio measures of association. What are they?4. Do the data provide evidence of effect measure modification on the ratio scale? Justify your answer.

= 12116000/42796000

3. Stratum specific for high lipid
