a. If no one dropped out of the study and no one developed Chlamydia infection during the study period, the total number of person-years = 10,000 person-years (2,000 x 5 years).

Person-years are the product of the number of people in a study and the amount of time each person spends in the study.

Thus, since there are 2,000 women in this study, who spend 5 years each, the person-years are 10,000 (2,000 x 5) person-years.

b. The estimated incidence rate of Chlamydia infection among women who participated in the study is 0.62 or 620 per 1,000 person-years (6,200/10,000).

An incidence rate describes the quickness of disease occurrence in a population. Since the incidence rate is based on person-time, it has some advantages over an incidence proportion, which measures the probability of developing a disease during the specified period.

Sample of young women = 2,000

Period of study = 5 years

Subjects newly diagnosed with infection = 440

Total number of person-years of subjects diagnosed = 6,200

Thus, the total number of person-years in the study is 10,000 person-years, while the incidence rate is 620 per 1,000.

g(-1) = 6

g(0) = 5

g(1) = 6

g(2) = 9

Step-by-step explanation:

Step 1: Plug in -1 for x

g(-1) = (-1)² + 5

g(-1) = 1 + 5

g(-1) = 6

Step 2: Plug in 0 for x

g(0) = 0² + 5

g(0) = 0 + 5

g(0) = 5

Step 3: Plug in 1 for x

g(1) = 1² + 5

g(1) = 1 + 5

g(1) = 6

Step 4: Plug in 2 for x

g(2) = 2² + 5

g(2) = 4 + 5

g(2) = 9

Answer:

The circle's circumference is approximately 106.81 centimeters.

Explanation:

The formula for the circumference of a circle is C = 2πr, where C is the circumference, π is pi (approximately 3.14), and r is the radius of the circle.

So, for a circle with a radius of 17 centimeters, its circumference can be found by:

C = 2πr

C = 2 x 3.14 x 17

C ≈ 106.81 cm

Therefore, the circumference of the circle is approximately 106.81 centimeters.

Here are the steps to simplify the expression \(\sf\:5x\sqrt{3x} - 2x\sqrt{3x} - x\sqrt{3x} \\\):

1. Combine like terms that have the same radical term \(\sf\:\sqrt{3x} \\\):

\(\sf\:(5x - 2x - x)\sqrt{3x} \\\)

2. Simplify the coefficients:

\(\sf\:2x\sqrt{3x} \\\)

Therefore, \(\sf\:5x\sqrt{3x} - 2x\sqrt{3x} - x\sqrt{3x}\) simplifies to \(\sf 2x\sqrt{3x} \\\).

There are 2 factor trees for 30.

Given that the number be 30 and we are required to find the number of factor trees.

Factor trees are basically a way of expressing the factors of a number, specifically the prime factorization of a number. Each branch in the tree is also split into factors. When the factor at the end of the branch is a prime number, the only two factors are itself and one so the branch stops and we circle the number.

30 can be divided into 6 and 5.

Now 6 can be divided into 2 and 3.

So there are 2 branches of trees.

The table below shows the ratios of boxed donuts to the cost.

Donuts    A       4        5     C

Cost    13.80  27.60   B   55.20

Now, By definition of ratio, we get;

⇒ A / 13.80 = 4 / 27.60

⇒ A = 13.80 × 4 / 27.60

⇒ A = 2.00

And,

⇒ 4 / 27.60 = 5 / B

⇒ B = 5 × 27.60 / 4

⇒ B = 34.5

⇒ 4 / 27.60 = C / 55.20

⇒ C = 55.20 × 4 / 27.60

⇒ C = 8

A three-dimensional structure called a rectangular prism has six faces, each of which is a rectangle. It is also referred to as a rectangular parallelepiped or a rectangular cuboid. In commonplace items like boxes, buildings, and furniture, rectangular prisms are utilised frequently in geometry, architecture, and engineering. A rectangular prism's surface area may be determined by adding the areas of all six sides, while its volume can be estimated by multiplying its length, width, and height.

18. The net of the rectangular prism is given by option a.

19. The surface area of the basket is given as:

The area of the front and back faces is = (19) x (10) = 190 cm² each.

The area of the top and bottom faces is (29) x (10) = 290 cm² each.

The area of the left and right faces is (29 ) x (19 ) = 551 cm² each.

The total surface area of the basket is:

SA = 2(190 cm²) + 2(290 cm²) + 2(551 cm²)

= 380 cm² + 580 cm² + 1102 cm²

= 2062 cm²

The missing angles of the triangle are

m∠b = 70°

m∠a = 110°

m∠c = 70°

m∠e = 110°

Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.

Corresponding angles

When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position

Alternate Interior Angles

Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.

Alternate Exterior Angles

The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

Consecutive Interior Angles

When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.

Given data ,

Let the triangle be represented as ABC

Now , the lines DE and AC of the triangle are parallel lines

So , from the theorem of parallel lines

The measure of ∠b + ∠AEC + 40° = 180° ( two sides are equal for an isosceles triangle )

So , the measure of m∠b = ( 180° - 40° ) / 2

The measure of m∠b = 70°

And , the measure of ∠b + ∠e = 180° ( angles on a straight line )

So , the measure of ∠e = 180° - 70°

The measure of m∠e = 110°

And , the measure of m∠e + measure of m∠c = 180° (Consecutive Interior Angles)

The measure of m∠c = 70°

And , the measure m∠a = the measure of m∠e ( alternate interior angles )

The measure of m∠a = 110°

Hence , the measures of angles are solved

Joanne and Ed Greenwood built a new barn with an attached arena. To finance the loan, they paid $1,326 interest on $47,600 at 4%. What was the time, using exact interest? (Do not round intermediate calculations. Round up your answer to the nearest day.)

Step-by-step explanation

Note that

Interest is represented by I=1326

The principal is represented by P=47,600

Rate is R =4%

And Time is year

Interest is calculated using the formulae,

I =PRT/100

From the above formulae, time can be calculated as

T=100I/PR

T= 100×1326/(47600×4)

T= 132600/190400

T= 0.6964 years

To convert to days, multiply by 365(since those no of days make a year)

T= 0.6964×365=254 days

This was approximated to the nearest day

Answer is 254 days

If you purchase dictionaries from Barker's Books rather than Sunshine Bookstore, you will receive each one for $0.50 less.

The total cost of a carton of 16 dictionaries at Sunshine Bookstore is $468, so the cost of each dictionary is:

$468 ÷ 16 = $29.25 per dictionary

At Barker's Books, the same dictionaries cost $28.75 each.

To find out how much money you will save on each dictionary if you buy them at Barker's Books, you need to subtract the cost of each dictionary at Barker's Books from the cost of each dictionary at Sunshine Bookstore:

$29.25 - $28.75 = $0.50

For the parabola,  x = 1/2(y-2)² - 4 we will use the equation x = 4p(y-k)² + h,

Vertex → (h, k)

In our given equation, (y - 2) → (y - k), so k = 2. The term on the rightmost side of our equation (-4) → h in the form, so we know h = -4. ∴  vertex (-4, 2).

focus → (h, k) = (-4, 2); P = 1/2

Parabola is symmetric around the x axis and so the focus lies a distance P, from the center, along the x axis.

∴  Focus is (-4 + p, 2)

(-4 + 1/2, 2) ⇒ (-7/2, 2)

directrix → x = d

Parabola is symmetric around the x axis and therefore the directrix is a line paralled to the y axis a distance away from the ceter (-4, 2) x coordinate.

∴ x = -4 - p   ⇒ x = -4 - 1/2

x = 9/2

focal chord endpoints →

The focus of the parabola is (-7/2, 2).

The y-coordinate of the focus is 2, so the y-coordinates of the endpoints of the focal chord are 2 + 1 and 2 - 1, → 3 and 1.
