Answer:
B. 90
Step-by-step explanation:
Since the two angles are supplementary, this means they both are on a flat line (180 degrees)
Since both A and B add up to 180, we take that number and subtract A (90) to get our answer: 90 degrees

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

surface to its core,
in miles?
Answer:
3959
Step-by-step explanation:
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
Distance from surface to its core = 3,959 miles

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?
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.

Answer:
C
Step-by-step explanation:
The following function describes the number of employees working at a company, In thousands, where trepresents the number of years since the company revised the benefits package.
f(t) = 1.5(0.90)^t
Consider the missing part of the question is "Select the correct statement.
A. The number of employees is increasing by 50% every year.
B. The number of employees is decreasing by 10% every year.
C. The number of employees is decreasing by 90% every year.
D. The number of employees is increasing by 90% every year."
Given:
The function is:
[tex]f(t)=1.5(0.90)^t[/tex]
Where, f(t) is the number of employees working at a company, in thousands and t is the number of years since the company revised the benefits package.
To find:
The correct statement from the given options.
Solution:
The general exponential decay model is:
[tex]f(t)=a(1-r)^t[/tex] ...(i)
Where, a is the initial value, r is the rate of decay and t is the number of years.
We have,
[tex]f(t)=1.5(0.90)^t[/tex]
It can be written as
[tex]f(t)=1.5(1-0.10)^t[/tex] ...(ii)
From (i) and (ii), we get
[tex]a=1.5,r=0.10[/tex]
The initial value is 1.5 and the rate of decay is 0.10 or 10%. It means the number of employees is decreasing by 10% every year.
Therefore, the correct option is B.

An executive traveled 1,930 miles by car and plane. He drove to the airport at an
average speed of 60 mph and the plane averaged 350 mph. The total trip took 8 hours.
How long did it take to get to the airport?
Answer:
It took 3 hours to get to the airport
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
