The 95% confidence interval for this population proportion is (0.10, 0.23).

A confidence interval is a range of values that are constrained by the statistic's mean and that are likely to include an unidentified population parameter. The proportion of likelihood, or certainty, that the confidence interval would include the real population parameter when a random sample is drawn several times is referred to as the confidence level.

Sample size n = 125

number of people who planned to take an extended vacation = 21

sample proportion p = 21/125 = 0.168

Confidence level = 0.95

significance level α = 1-0.95 = 0.05

Z score =[tex]Z_{\alpha 2}[/tex] = Z(0.05) = 1.96, from Z table.

Answer:

Step-by-step explanation:

To solve this problem, we need to calculate Martha's out-of-pocket expenses, and the total amount of money she had to pay for her medical bills.

First, we need to calculate the amount of money Martha had to pay toward her deductible. Since her deductible is $200, this is the amount she had to pay out of pocket.

Next, we need to calculate the amount of money Martha had to pay toward her co-payment. Since her co-payment is 20%, we can calculate this by multiplying her medical bills by the co-payment rate: $6,500 x 0.2 = $1,300.

To find Martha's total out-of-pocket expense, we can add the amount she paid towards her deductible ($200) and the amount she paid towards her co-payment ($1,300):

$200 + $1,300 = $1,500

Therefore, Martha's out-of-pocket expense was $1,500.

Martha's insurance required her to pay a $200 deductible and a 20% co-payment on the remaining balance of her medical bills. After paying the deductible, she pays 20% of the remaining $6,300 which is $1,260. So, Martha's total out-of-pocket expense was $1,460.

Martha's health insurance plan includes a $200 deductible and a 20% co-payment. The deductible is the amount Martha has to pay before the insurance company starts to pay. In this case, Martha first pays a $200 deductible from her $6,500 medical bills, which leaves her with $6,300 to be covered by insurance and her co-payment. The 20% co-payment means Martha is responsible for paying 20% of the remaining $6,300. To calculate this, we multiply $6,300 by 0.20 (20%), which equals $1,260. Therefore, Martha's total out-of-pocket expense for her medical bills last year was the $200 deductible plus the $1,260 co-payment, equalling $1,460.

Answer:

Equation of side AB:

We know the coordinates of A and B, so we can use the point-slope form to create the equation of the line:

y - 3 = (3/5)(x - 5)

y - 3 = 3/5x - 15/5

5/3y - 15/3 = x - 5

5/3y - x = -15/3 + 5

5/3y - x + 15/3 = 5

5/3y - x + 15/3 = 0

Equation of side AB: 5/3y - x + 15/3 = 0

Equation of side DC:

We know the coordinates of C and D, so we can use the point-slope form to create the equation of the line:

y - 1 = (2/5)(x - 10)

y - 1 = 2/5x - 20/5

5/2y - 10 = x - 10

5/2y - x = -10

5/2y - x - 10 = 0

Equation of side DC: 5/2y - x - 10 = 0

Equation of side BD:

We know the equation of side BC (x - 2y = 8) and that consecutive sides are perpendicular, so we can use the slope-intercept form to find the equation of line BD:

Slope of BC = -2/1

Slope of BD = -1/-2 = 1/2

y = (1/2)x + b

We can use the coordinates of B to find b:

1 = (1/2)(8) + b

2 = 4 + b

b = -2

Equation of side BD: y = (1/2)x - 2

To find a Riemann sum that gives an upper estimate of the double integral, we need to divide the region of integration into small subregions (in this case, squares) and take the maximum value of f(x, y) over each subregion.

The Riemann sum will then be the sum of the areas of the subregions times the maximum value of f(x, y) over each subregion.

For example, if we divide the region of integration into four squares, the Riemann sum would be given by:

Riemann sum = (area of first square) * (maximum value of f(x, y) in first

                           square) + (area of second square) * (maximum value of

Step-by-step explanation:

* i used a scientific calculator for my working. i am not sure if calculators are permitted for your exam on Wednesday *

⭐AB = AD + DB

⭐AB = 16.5 + DB

Thus, we need to find DB in order to solve for AB.

First, I utilized the triangle sum theorem to find ∠BDC:

[tex]< BDC + < DCB + < B = 180\\ < BDC + 59 + 90 = 180\\ < BDC + 149 = 180\\ < BDC = 31[/tex]

Then, I utilized the linear pair sum to find ∠ADC:

[tex]< ADC + < BDC = 180\\ < ADC + 31 = 180\\ < ADC = 149[/tex]

Next, I utilized the triangle sum theorem to find ∠DAC:

[tex]< DAC + < ADC + < ACD = 180[/tex]

[tex]< DAC + 149 + 10 = 180[/tex]

[tex]< DAC + 159 = 180[/tex]

[tex]< DAC = 21[/tex]

After, I utilized the law of sines to find DC:

[tex]\frac{sin10}{16.5} = \frac{sin21}{DC}[/tex]

[tex]DCsin10 = 16.5sin21[/tex]

[tex]DC = \frac{16.5sin21}{sin10}[/tex]

[tex]DC = 34.052[/tex]

Then, I utilized the sine function to find DB for ΔBDC:

[tex]sin(59) = \frac{DB}{34.052}[/tex]

[tex]34.052sin(59) = DB[/tex]

[tex]29.188 = DB[/tex]

Finally, I substituted DB into our original equation for AB:

[tex]AB = AD + DB[/tex]

[tex]AB = 16.5 + 29.188[/tex]

[tex]AB = 45.688 metres[/tex]

The height of the pole will be equal to 45 meters.

Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous distinctive trigonometric identities that relate to a triangle's side length and angle.

Given that the angle BCD is 59 and the angle BCA is 69. The height will be calculated as,

tan(59) = BD / BC

BC = BD / tan(59)

BC = 0.6BD

tan(69) = AB / BC

tan(69) = ( 16.5 + BD ) / BC

BC = 0.38( 16.5 + BD )

Equate the values of BC,

0.6BD = 0.38 ( 16.5 + BD )

0.6BD = 6.27 + 0.38BD

0.22BD =6.27

BD = 28.5 meters

The height of the pole is,

AB = AD + DB

AB = 16.5 + 28.5

The equation in slope intercept for the given line is  y = -2/3x - 28/3.

What is Slope ?

The slope or gradient of a line in mathematics is a number that indicates the line's steepness and direction.

Given,  the line crosses the x-axis at 14 and is parallel to the line represented by y= -2/3x+6.

We know that two parallel lines always have the same slope.

We can say that the line has coordinate as (14,0) and slope (m) as -2/3.

We know that the slope-intercept form of the line is,

                    y= mx + b

Now, We put x=14, y=0 and m=-2/3 in equation above,

We get, 0 = -2/3 × 14 + b

The exponential growth model for the number of bacteria in the sample after x hours is    [tex]P ( x ) = 200 e ^{(\frac{ln 4}{8})x }[/tex]

What is exponential growth factor?

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the equation for the number of bacteria in the sample after x hours = P

The value of the equation P ( x ) is given by

After 4 hours , the sample contained 400 bacteria

So ,

when x = 4

[tex]P ( 4 ) = ae ^{4b }=400[/tex]   be equation (1)

After 12 hours , the sample contained 1600 bacteria

And , when x = 12

[tex]P ( 12 ) = ae ^{12b }=1600[/tex]   be equation (2)

Divide equation (2) by equation (1) , we get

[tex]\frac{P ( 12 )}{P ( 4 )} = \frac{ae ^{12b }}{ae ^{4b }} = \frac{1600}{400}[/tex]

On simplifying the equation , we get

e¹²ᵇ⁻⁴ᵇ = 4

e⁸ᵇ = 4

Taking logarithm on both sides of the equation , we get

8b = ln (4)

Divide by 8 on both sides , we get

b = ln (4) / 8

Substituting the value for b in equation (1) , we get

[tex]ae ^{4*ln (4) / 8 }=400[/tex]

[tex]ae ^{ln (4) / 2}=400[/tex]

On simplifying the equation , we get

a x 2 = 400

Divide by 2 on both sides of the equation , we get

a = 200

Therefore , the exponential growth equation is given by

Substitute the values of a and b in the equation , we get

[tex]P ( x ) = 200 e ^{(\frac{ln 4}{8})x }[/tex]

[tex]E[/tex]ach pajama costs $32

Step-by-step explanation:

So, the said person bought:

2 slippers at a price, 3 pajamas at another price. (The prices are unknowns, s, and p)

Each slippers cost $12

We are to find the cost of each pajama, where the total purchase price is $120

With the given conditions, we formulate an equation: 2s + 3p = 120

Since s = 12, we replace for the value of s in the equation. s becomes 2 × 12 = 24.

The new equation is then: 24 + 3p = 120, where we are to find the value of p.

Collect like terms: 3p = 120 - 24 → 3p = 96

Divide both sides of the equation by 3 to find the value of p: 3p/3 = 96/3 → p = 32

Therefore, the price of each pajama is $32
