5. Suppose that a study of oral contraceptive (OC) use and development of bacteriuria was conducted among 2,390 women, all of whom were initially free from bacteriuria. At the start of the study, the women were surveyed to determine whether or not they currently used OCs. 482 were using OCs and 1908 were not. By the end of the follow-up period, a total of 27 of the OC users and 77 of the non-users had developed bacteriuria. Shambhavi A. Is this a cohort study or an experimental study
Answer:
Cohort study
Step-by-step explanation:
The study described above is closely related to a cohort study in that Cohort studies mainly observes the participants who might or might not have been exposed to a particular effect or drug, in this case the oral contraceptive and bacteriuria development. The effect of exposure is observed for a certain period time usually called the follow-up period. Conversely, experimental study will require that participants are divided into groups with one group being exposed to the treatment while the other will be the placebo.This isn't the case in the study described above, hence, it is closely related to a cohort study.

Answer: 51
Step-by-step explanation: QTR is the inscribed angle, so QTR = 1/2 * QSR, so QSR = 78. QSR is an isosceles triangle, since it uses the radius of the circle twice, so QRS = (180 - 78)/2 = 51

a. defining the objective
b. collecting relevant data
C. generating possible options
d. implementing and evaluating
Answer:
C.
b. would be ahead of brainstorming
The answer is Option C , generating possible options is directly related to brainstorming .
What is Decision Making ?Decision making can more accurately be viewed as a process. It rarely occurs at one instance.
By viewing Decision making as a process managers are more likely to be able to identify and assess the issues associated with making the decision.
By taking a more process driven approach, you will be more likely to lead a broader acceptance of the decision—and to more effective implementation
Generating possible options is directly related to brainstorming.
Phase 1 of the Decision making process
To establish a context for success , this is the point at which you set the parameters for the decision making process.
Phase 2: of the Decision making process:
Assessing the situation and choosing a course of action--- when you determine the root cause of the issue you are trying to resolve and discuss possible solutions.

Find the polynomial of degree 3 such that the coefficient of x2
is three less than the coefficient
of x3
; the coefficient of x is 3 times the coefficient of x2
; and the constant term is two more than
the coefficient of x3
. The sum of the coefficients is -4.
Answer:
1/5[8x³ –7x² –21x + 18]
Step-by-step explanation:
Let the polynomial be:
ax³ + bx² + cx + d
Where:
a => is the coefficient of x³
b => is the coefficient of x²
c => is the coefficient of x
d => is the constant term.
From the question given above,
Coefficient of x² (b) = a – 3 ..... (1)
Coefficient of x (c) = 3b ...... (2)
Constant term (d) = 2 + a ..... (3)
Sum of coefficient (a + b + c) = –4
a + b + c = –4
b = a – 3
c = 3b = 3(a – 3)
a + b + c = –4
a + (a – 3) + 3(a – 3) = –4
a + a – 3 + 3a – 9 = –4
Collect like terms
a + a + 3a = –4 + 3 + 9
5a = 8
Divide both side by 5
a = 8/5
Substitute the value of a into equation (1)
b = a – 3
a = 8/5
b = 8/5 – 3
b = (8 – 15)/5
b = –7/5
Substitute the value of b into equation (2)
c = 3b
b = –7/5
c = 3(–7/5)
c = –21/5
Substitute the value of a into equation (3)
d = 2 + a
a = 8/5
d = 2 + 8/5
d = (10 + 8)/5
d = 18/5
SUMMARY:
a = 8/5
b = –7/5
c = –21/5
d = 18/5
Thus, the polynomial:
ax³ + bx² + cx + d
8/5x³ + (–7/5)x² + (–21/5)x + 18/5
8/5x³ –7/5x² –21/5x + 18/5
1/5[8x³ –7x² –21x + 18]

Answer:
x ≈ 0.309906932381 or 4
Step-by-step explanation:
There are no algebraic methods of solving a mixed exponential and polynomial equation. The value of x can be found by guessing, or by other means such as trial and error or graphing.
Attached is a graph showing two solutions. x = 4 is the integer solution (2^4 = 4·4). The irrational solution is approximately x ≈ 0.309906932381. That precision is obtained by Newton's method iteration, easily done by a graphing calculator.

Cindy owns a plot of land measuring 630 yards wide by 987 yards long what is the area of the land in square yards, square feet, acres and square miles
Answer:
621,810 square yards
1,865,430 square feet
128.47 acres
353.30 square miles
Step-by-step explanation:
Since Cindy owns a plot of land measuring 630 yards wide by 987 yards long, to determine what is the area of the land in square yards, square feet, acres and square miles, the following calculations must be performed:
1 yard = 3 feet
1 square yard = 0.000206612 acres
1 yard = 0.000568182 miles
Square yards: 630 x 987 = 621,810 square yards
Square feet: 621,810 x 3 = 1,865,430 square feet
Acres: 621,810 x 0.000206612 = 128.47 acres
Square miles: 621.810 x 0.000568182 = 353.30 square miles
Given a triangle with B = 41˚, a = 21, and b = 12. Approximate the measure
of angle A to the nearest 0.1˚.
5. Explain how you could use compatible numbers to estimate 245 ÷ 3. Then estimate the quotient.
Answer:
8
Step-by-step explanation:
Compatible numbers are defined as the numbers which are very close to the numbers that they are replacing that divides evenly into each other.
In the context, we have to estimate the quotient using the compatible numbers in order to estimate 245 divided by 3.
So, estimating 245 as 240 and 3 as 30.
Here, 240 is very close to 245 and 30 is close to 3. So the quotient is the result when we divide 240 by 30 and it divides evenly into 240.
We first divide the non zero parts of each number i.e. 24 by 3 to get the first part of the estimate.
Then we add on the zero if there were left in the problem to get your estimate.
Therefore,
240 / 30 = 8
So here, the quotient is estimated as 8.
in an equilateral triangle, the incenter, orthocenter, circumcenter, and centroid are __________.
A. On the same line
B. Unequal
C. Imaginary
D. The same point
Answer:
D. The same point
Step-by-step explanation:
An equilateral triangle can be defined as a type of triangle that has all of its sides being equal in length.
This ultimately implies that, an equilateral triangle comprises of three (3) congruent sides and as such creates three (3) congruent angles that measures 60° each. Also, the sum of the congruent angles of an equilateral is always equal to 180°.
Hence, in an equilateral triangle, the incenter, orthocenter, circumcenter, and centroid are the same point i.e all of the three (3) centers fall on the same point or spot.
A computer program found that the line c=2t−89c=2t−89c=2t−89 is a good fit for the data. Use this equation to predict how many cups of lemonade Lin might sell on a day when the high temperature is 74 degrees.
Answer:
58cups
Step-by-step explanation:
Given the equation for the line as c = 2t - 89
If the temperature is 74 degrees, then we can find the number of cups at this temperature;
Substitute t = 74 unti the expression
x = 2(74) - 89
c = 147 - 89
c = 58cups
Hence the number of cups of lemonade is 58cups

Step-by-step explanation:
Mean is just another word for "the average."
To get the mean, you first need to add up al of your values together.

Each year a certain type of tree grows vertically 14/15 as much as it did the year before. If the tree grows 1.5m during the first year, how much growth will it have in 20 years?
https://answers.yahoo.com/question/index?qid=20180411132938AApZYZz
The required growth of the tree after 20 years is 3, 813 meters.Here,
Given that,
Each year a certain type of tree grows vertically 14/15 as much as it did the year before. If the tree grows 1.5m during the first year.
To determine how much growth will it have in 20 years.
The function which is in format f(x) =a^x where a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
The tree grows vertically 14/15 as much as it did the year before.
= 1.5 * 14 / 15
= 1.5 * 0.94
= 1.41
Total growth after 1 year = 1.5 + 1.41
= 2.91
Percentage growth = 1.41 / 2.91 = 0.48%
Now,
Growth after 20 years,
= 1.5 (1 + 0.48)^20
= 1.5(1.48)^20
= 3,813.51
Thus, the required growth of the tree after 20 years is 3, 813 meters.
