Answer:
This is a Retrospective study
Step-by-step explanation:
Retrospective study is a study that compares two groups of people; those with disease or condition under study and a very similar group of people who do not have the disease or condition.
Here they are compring those men with high blood pressure who drank and those with no high blood pressure and don't drink.
Using a system of equations, it is found that Charlie won $270.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Amount earned by Linda.
- Variable y: Amount earned by Charlie.
Linda won $10 less than three times as much as Charlie, hence:
x = 3y - 10
Linda won $800, hence the amount won by Charlie is found as follows:
800 = 3y - 10
3y = 810
y = 810/3
y = 270

The equation of line parallel to
and containing the point(-10,-3) is 
Step-by-step explanation:
We need to write the equation parallel to and containing the point(-10,-3)
The standard form of point slope equation is:
where m is slope and b is y-intercept
Comparing the given equation with standard form the slope is m= -1/5
Since the lines are parallel the slope of new line is m = -1/5
Now finding b (y-intercept)
Using slope m=-1/5 and point (-10,-3)
So, b= -5 and slope = -1/5 the equation of new line is:
So, The equation of line parallel to and containing the point(-10,-3) is

The probability that Mae will roll an odd number
<u></u><u></u>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
<em>Given that Mae has a number cube with 6 sides that are numbered 1 through 6.</em>
<em>n(S) = { 1,2,3,4,5,6,} = 6</em>
<em>Let 'E ' be the event of odd numbers</em>
<em>Mae will roll an odd number</em>
<em>n(E) = {1, 3, 5} = 3</em>
<u>Step(ii):-</u>

Answer:
A) H+4
Step-by-step explanation:
I do this in a different way, but i'll do it in both
Mine:
30 ÷ 2 = 15
4 ÷ 2 = 2
15+2, 15 -2
17, 13
Kristen Has 17
Yours:
h+(h+4)=30
-4 -4
h+h = 26
2h = 26,
h = 13, Back to the equation, use 13 as a sub. for all the h's
13+(13+4) = 30
13 + 17 = 30
Hope this helps!
