A researcher finds 200 women over 50 who exercise regularly, pairs each with a woman who has a similar medical history but does not exercise, then follows the subjects for 10 years to see which group develops more cancer. this is a prospective study.

<h3>Define prospective study.</h3>

Individuals are tracked over time in prospective studies, and information is gathered about them as their characteristics or circumstances change. Prospective studies include things like birth cohort studies. In retrospective research, people are sampled, and details about their past are gathered. Always after a predetermined number of incidents, the analysis takes place. The fact that individuals were enrolled and baseline data was obtained before any subjects experienced an outcome of interest identifies a study as prospective.

6³ ÷ 4 + 2 x 9(32 x 8 – 17 x 4).
inn [45]

ANSWER

3438

EXPLANATION:

<em>PARENTHESIS FIRST</em>

32 x 8 = 256

17 x 4 = 68

256 - 68 = 188

(<u>now the equation is, 6³ ÷ 4 + 2 x 9 (188))</u>

<u />

<em>EXPONENTS NEXT</em>

6³= 216

(<u>now the equation is, 216 ÷ 4 + 2 x 9 (188))</u>

<u />

<em>MULTIPLICATION AND DIVISION NEXT (left to right)</em>

216 ÷ 4 = 54

2 x 9 = 18

18 x 188 = 84

(<u>now the equation is, 54 + 3384)</u>

<u />

<em>LASTLY ADDITION AND SUBTRACTION (left to right)</em>

54 + 3384 = 3438

Ta-da!

Find the equation of the line through (-9,6) that is perpendicular to the line through (7,8),
Setler [38]

Step-by-step explanation:

I assume as "equation" we mean the slope-intercept form :

y = ax + b

"a" is the slope of the line (y coordinate change / x coordinate change when going from one point to another on the line). b is the y-intercept (the y value when x = 0).

we get the slope by finding the perpendicular slope of the first line.

the slope of the first line when going from (-3, -9) to (7, 8) :

x changes by + 10 (from -3 to +7).

y changes by + 17 (from -9 to +8).

so, that slope is 17/10.

the perpendicular slope is turning the original slope upside-down and flips the sign :

-10/17

so, a = -10/17

now, as we have only the slope and a point of the new line, we can use the point-slope form to stay and then transfer into the slope-intercept form.

y - y1 = a(x - x1)

where "a" is again the slope, and (x1, y1) is a point on the line

y - -6 = -10/17 × (x - -9)

y + 6 = -10/17 × (x + 9) = -10/17 × x - 90/17

y = -10/17 × x - 90/17 - 6 =

= -10/17 × x - 90/17 - 102/17 =

= -10/17 × x - 192/17

so, the equation is (in a maybe nicer way)

y = -1/17 × (10x + 192)

Which system of inequalities has a solution set that is a line?
andre [41]

Answer:

x + y ≥ 3

x + y ≤ 3

Step-by-step explanation:

In the picture attached, the problem is shown.

The solution to the system:

x + y ≥ 3

x + y ≤ 3

is the line x + y = 3

In order to get a solution to a system of inequalities that is a line, we need the same equation on the left (here, x + y), the same constant on the right (here, 3), and the ≥ sign in one inequality and the sign ≤ in the other one.
