Lydias hotel room number has three digits.The hundreds digit has a value of 40 Tens.The Tens digit is greater than 6. Which could be Lydias hotel room number?
Answers
Any 3 digit number can be expressed in the form of:
[tex](a*100)+(b*10)+(c*1)[/tex]
Where [tex]a, b, c[/tex] represent any natural number from 0 to 9.
We are told the hundreds number (this means [tex]a*100[/tex] in the expression above) is equal to the value of 40 tens, 40 tens is 400. Then, we know the digit in the tens is greater then 6, this means [tex]b>6[/tex] in the expression above.
So, there are multiple numbers the room number could be, namely:
[tex]400+(b*10)+(c*1)\\[/tex]
where [tex]b[/tex] can be 7, 8, or 9; and [tex]c[/tex] can be 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. So, there's 30 possible room numbers Lydia may be.

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?
Answers
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.

Step-by-step explanation: Can I get brainliest? Thanks!
Total distance = 1930
Car speed avg = 60 miles per hour
Plane speed avg = 350 miles per hour
Time = 8 hours
(60*3)+(350*5)=1930 (Try combinations of 3+5, 4+4, 2+6 etc)
It took 3 hours to get to the airport

entertainment Gh12,000
exigencies Gh23,020
(a) what percentage of the income is spent on salaries.
(b) what is the ratio of the amount for housing to the amount for training,
Answers
Answer:
(a) 19%
(b) 5:6
Step-by-step explanation:
Given: Gh 258,000
salaries Gh 49,020
training Gh 72,000
housing Gh 60,000
entertainment Gh 12,000
exigencies Gh 23,020
(a) Percentage of the income spent on salaries = [tex]\frac{amount of salaries}{total income}[/tex] x 100
= [tex]\frac{49020}{258000}[/tex] x 100
= 0.19 x 100%
= 19%
The percentage of the income spent on salaries is 19%.
(b) Ratio of amount for housing to amount for training = [tex]\frac{amount for housing}{amount for training}[/tex]
= [tex]\frac{60000}{72000}[/tex]
= [tex]\frac{5}{6}[/tex]
The ratio of the amount for housing to the amount for training is 5:6
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.
Answers
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

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
