Answer:
2.75 minutes
Step-by-step
divide 55 by 20
Answer:
2.75 minutes/2 minutes and 45 seconds
Step-by-step explanation:
Divide: 55 divided by 20=2.75
2.75 minutes= 2 minutes and 45 seconds
The reason why you divide 55 divided by 20 is because you are trying to find how long it took you to clear 1 street.
And there are 20 streets and each street took you 2 minutes and 45 minutes to complete 1 street.

Distance from surface to its core is 3,959 miles
Distance based problem:Given that;
Diameter of earth = 7,918 miles
Find:
Distance from surface to its core
Computation:
Radius of earth = Distance from surface to its core
Distance from surface to its core = 7,918 / 2

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.
Step-by-step explanation:
1. Is a table which is contained in the attachment
2. The crude ratio measure
= 4000x3000+20*5800/7000*6000+200*3980
= 12000000+116000/42000000+796000
= 12116000/42796000
= 0.283
3. Stratum specific for high lipid
= 12000000/42000000
= 0.285
= 0.29
Stratum specific for chf
= 116000/796000
= 0.145
= 0.15
4. High lipid has higher risk than chd from the solution here

continuous or discrete? Explain.
k
Share with class
Answer:
discrete
Step-by-step explanation:
the domain represents the number of terms and it only has natural numbers
The domain for the nth term A(n) of the sequence 26, 39, 52, 65, 78 is discrete.
What is a discrete function?When the domain and range of a function are discrete sets of values rather than intervals, the function is said to be discrete.
The given sequence is 26, 39, 52, 65, 78.
Since, Domain represents the real sets of values,
In the given sequence, the number in the sequence is real.
Also, the sequence is a discrete set of values,
Implies that, the domain of the function A(n) is discrete.

To visit his grandmother, Luis takes a train 6.376.376, point, 37 kilometers and a car 5.455.455, point, 45 kilometers.
How many kilometers is Luis's journey in total?
Answer:
Luis traveled 11.82 km in total.
Step-by-step explanation:
The statement should say: To visit his grandmother, Luis takes a train 6.37 kilometers and a car 5.45 kilometers. How many kilometers is Luis's journey in total?
Hence, to find the total distance traveled by Luis we must add the distances of the train (6.37 km) and the car (5.45 km):
[tex] d = d_{t} + d_{c} = 6.37 km + 5.45 km = 11.82 km [/tex]
Therefore, Luis traveled 11.82 km in total.

Total distance = 1930
Car speed avg = 60 miles per hour
Plane speed avg = 350 miles per hour
