The nurse should administer 19.958 mg of furosemide per dose to the toddler.

To use the unitary method, we need to convert the toddler's weight from pounds to kilograms, as the dose is given in mg/kg/day.

1 lb = 0.45359237 kg (conversion factor)

Therefore, the toddler's weight in kilograms is

22 lb x 0.45359237 kg/lb = 9.979 kg (rounded to three decimal places)

Now we can calculate the total daily dose of furosemide for the toddler

4 mg/kg/day x 9.979 kg = 39.916 mg/day (rounded to three decimal places)

Since the dose is divided into 2 equal doses daily, each dose would be half of the total daily dose

39.916 mg/day ÷ 2 = 19.958 mg/dose (rounded to three decimal places)

Part A: Two-way radio A covers approximately 201 square miles.

Part B: Two-way radio B covers approximately 483 square kilometers.

Part C: Two-way radio A covers the larger area.

Part D: The scale factor relationship between the radio coverages is approximately 0.8746.

What is area of circle?

The area of a circle can be found using the formula A = πr², where A is the area and r is the radius of the circle.

Part A: For two-way radio A, the radius is 8 miles, so the area covered by the radio is:

A = π8²

A = 64π

A ≈ 201 square miles

Therefore, two-way radio A covers approximately 201 square miles.

Part B:For two-way radio B, the radius is 11.27 kilometers. We need to convert this to miles in order to use the formula for the area of a circle.

1 kilometer is equal to 0.621371 miles (to 6 decimal places).

So, 11.27 kilometers is equal to: 11.27 km × 0.621371 mi/km = 7.00142 miles

Now, we can find the area covered by two-way radio B:

A = π(7.00142)²

A = 153.94π

A ≈ 483 square kilometers

Therefore, two-way radio B covers approximately 483 square kilometers.

Part C:

We can compare the areas covered by the two-way radios by using their respective areas calculated in Part A and Part B.

Area covered by two-way radio A = 201 square miles

Area covered by two-way radio B = 483 square kilometers

We need to convert the area covered by two-way radio B to square miles in order to compare the two areas. We know that 1 mile is equal to 1.61 kilometers, so:

1 square mile = (1.61)² square kilometers

1 square kilometer = (1/1.61)² square miles

1 square kilometer = 0.386 square miles (rounded to 3 decimal places)

Therefore, the area covered by two-way radio B in square miles is:

483 km²× 0.386 mi²/km² ≈ 186 square miles

Now we can compare the two areas:

Area covered by two-way radio A = 201 square miles

Area covered by two-way radio B = 186 square miles

Since 201 is greater than 186, two-way radio A covers the larger area.

Part D:

To determine the scale factor relationship between the radio coverages, we can compare their radii.

The radius of two-way radio A is 8 miles.

The radius of two-way radio B is 11.27 kilometers, which is approximately 6.997 miles (as calculated in Part B).

The scale factor is the ratio of the radii of the two circles.

So,scale factor = radius of two-way radio B / radius of two-way radio A

scale factor = 6.997 / 8

scale factor ≈ 0.8746

Therefore, the scale factor relationship between the radio coverages is approximately 0.8746.

a)The probability that at least 10 of the 15 randomly chosen individuals have no citations is 0.6723.  b) the probability that fewer than half of the 15 randomly chosen individuals have at least one citation is 0.3826. c) the probability that the number of individuals among 15 who have at least one citation is between 5 and 10, inclusive, is 0.7278.

Recall that in Exercise 30 (Section 3.3) the pmf of Y, the number of traffic citations for a randomly selected individual insured by a particular company, was given as follows:

Y=y 0 1 2 3 4 5

P(Y=y) 0.52 0.29 0.10 0.05 0.03 0.01

a. We can use the binomial distribution to model the number of individuals among 15 who have no citations, with the probability of success being P(Y=0)=0.52. Then, the probability of at least 10 individuals having no citations is:

P(X >= 10) = 1 - P(X < 10) = 1 - P(X <= 9)

Using a binomial table or calculator, we find that:

P(X <= 9) = 0.3277

Therefore,

P(X >= 10) = 1 - P(X <= 9) = 1 - 0.3277 = 0.6723

b. We can use the binomial distribution again to model the number of individuals among 15 who have at least one citation, with the probability of success being P(Y>0)=1-P(Y=0)=1-0.52=0.48. Then, the probability of fewer than half (less than 7) individuals having at least one citation is:

P(X < 7) = Σ P(X = k), where k = 0,1,...,6

Using a binomial table or calculator, we find that:

P(X < 7) = 0.6174

Therefore,

P(X >= 7) = 1 - P(X < 7) = 1 - 0.6174 = 0.3826

c. We need to find the probability that the number of individuals among 15 who have at least one citation is between 5 and 10, inclusive. We can use the binomial distribution with the probability of success being P(Y>0)=0.48. Then, the probability is:

P(5 <= X <= 10) = Σ P(X = k), where k = 5,6,...,10

Yes, the ratio of the hypotenuse to a leg is the same for all isosceles right triangles.

What is hypotenuse ?

In a right triangle, the hypotenuse is the side that is opposite to the right angle. It is also the longest side of the triangle. The hypotenuse is always opposite the right angle and is found using the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. In a right triangle with legs of length "a" and "b", the length of the hypotenuse "c" can be found using the formula:

[tex]c^2 = a^2 + b^2[/tex]

Taking the square root of both sides gives us:

[tex]c = \sqrt{a^2 + b^2}[/tex]

The hypotenuse plays an important role in trigonometry, as it is used in the calculation of trigonometric ratios such as sine, cosine, and tangent.

According to the question:
Yes, the ratio of the hypotenuse to a leg is the same for all isosceles right triangles.

In an isosceles right triangle, the two legs are congruent, which means they have the same length. Let's call the length of each leg "a". The hypotenuse of the triangle can be found using the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the legs:

[tex]hypotenuse^2 = a^2 + a^2 = 2a^2[/tex]

Taking the square root of both sides, we get:

[tex]hypotenuse = \sqrt{2a^2} = a * \sqrt{2}[/tex]

So, the ratio of the hypotenuse to a leg is:

[tex]hypotenuse / a = (a * \sqrt{2}) / a = \sqrt{2}[/tex]

This shows that the ratio of the hypotenuse to a leg in an isosceles right triangle is always equal to the square root of 2, which is a constant value. Therefore, the ratio is the same for all isosceles right triangles.

Step-by-step explanation:

The cash back you would receive on your purchases of $2,738.21 using this credit card is $33.92.

To calculate the cash back you would receive using the given credit card, we need to multiply the total amount spent in each category by the corresponding cash back percentage, and then add up those amounts.

For gas purchases, you spent $134.92, so the cash back earned on that amount would be:

$134.92 x 3% = $4.05

For grocery store purchases, you spent $384.23, so the cash back earned on that amount would be:

$384.23 x 2% = $7.68

For all other purchases, you spent a total of:

$2,738.21 - $134.92 - $384.23 = $2,219.06

So the cash back earned on that amount would be:

$2,219.06 x 1% = $22.19

Adding up the cash back earned in each category, we get:

$4.05 + $7.68 + $22.19 = $33.92

When P(opposed | Grade 12) exceeds P(Grade 12 | opposed), the correct response is: P(opposed | Grade 12) P(opposed | Grade 12) (Option C)

An arrangement of things in a particular order is known as a permutation in mathematics. In more detail, an arrangement of a set's members in a certain order is known as a permutation. To give one example, the set 1, 2, 3 contains six permutations: 1, 2, 3, 1, 2, 3, 1, and 3, 2, 1. The formula P(n, r) is frequently used to express permutations, which are the various methods to select r things from a group of n objects and arrange them in a particular order. P(n, r) has the following formula: P(n, r) equals n!/(n-r)!  where the factorial of n is represented by n! (i.e., the product of all positive integers from 1 to n).

given

Using Bayes' theorem, we can contrast P(Grade 12 | opposed) with P(grade 12 | opposed):

Grade 12 opposition formula: P(opposed) = P(Grade 12 opposition) * P(opposed) / P (Grade 12)

The table contains the values we require:

P(grade twelve) = (12+6+11)/(5+3+9+8+12+9+15+16+10+12+6+11) = 0.15 P(opposition) = (3+12+16+6)/(5+3+9+8+12+9+15+16+10+12+6+11) = 0.5 P(opposition | grade twelve) = 6/(12+6+11) = 0.24

Although we do not directly know the value of P(Grade 12 | opposed), we can calculate it using the following formula:

P (12th grade | opposed) = P (12th grade | opposed) * P (12th grade | opposed) / P (12th grade | opposed) = 0.24 * 0.15 / 0.5 = 0.072

As a result, we have:

P (12th grade | opposed) = 0.072 P (12th grade | opposed) = 0.24

When P(opposed | Grade 12) exceeds P(Grade 12 | opposed), the correct response is: P(opposed | Grade 12) P(opposed | Grade 12) (Option C) .

Step-by-step explanation:

The sprinkler will water an area of approximately 1519.76 square feet.

Area is the measurement of the size of a surface or region. It is usually measured in square units such as square meters, square feet, or square inches.

The area watered by the sprinkler can be calculated using the formula for the area of a circle:

Area = πr²

where r is the radius of the circle.

In this case, the radius of the sprinkler's spray is given as 22 ft. So, we can substitute this value in the formula:

Area = π(22 ft)²

Area = π(484 ft²)

Area = 1519.76 ft² (rounded to two decimal places)

Therefore, the sprinkler will water an area of approximately 1519.76 square feet.

F(x) = P(X ≤x)

      = 1 - e^(-x/μ)

Mean time between taxi arrivals is 24 minutes,

Rate parameter

λ = 1/μ

  = 1/24.

Probability of waiting longer than one hour for a taxi,

Probability that the time between arrivals is greater than 60 minutes. Using the cumulative distribution function,

P(X > 60)

= 1 - P(X ≤ 60)

= 1 - (1 - e^(-60/24))

= e^(-2.5)

Let's start by finding out how much money Keiko spent on coffee. She started with an $80 gift card and ended up with $43.15 left, so she spent:

$80 - $43.15 = $36.85

We also know that the coffee costs $7.37 per pound. Let's use "x" to represent the number of pounds of coffee Keiko bought. Then we can set up an equation:

$7.37x = $36.85

To solve for x, we can divide both sides by $7.37:

x = $36.85 ÷ $7.37

x = 5

So Keiko bought 5 pounds of coffee.

According to given information, the area of kite is 480 m².

What is area of kite?

The area of a kite can be calculated by multiplying the lengths of its two diagonals and dividing the result by 2:

Area of kite = (diagonal 1 x diagonal 2) / 2

The hypotenuse is usually the slanted line in a triangle.

Area of a kite = pq/2 (p and q = diagonal)

Finding the missing side length of triangle₁

37² = 12² + x² (x = unknown side length)

=> 1369 = 144 + x² (x = unknown side length)

=> 1369 - 144 = x² (x = unknown side length)

=> 1225 = x² (x = unknown side length)

=> x = 35 m

Finding the area:

Area of a kite = pq/2 (p and q = diagonal)

=> Area of a kite = (35 + 5)(12 + 12)/2

=> Area of a kite = (40)(24)/2

=> Area of a kite = 40 x 12 = 480 m².

Therefore, the area of kite is 480 m².

Using concrete pavers for the patio flooring is a cost-effective and durable option for Mr. Manley's project. Approximately 176 pavers will be needed to cover the 3.2 m x 5.0 m area of the patio.

Based on Mr. Manley's request for the most economical option for the patio flooring, I would suggest using concrete pavers. Concrete pavers are a durable and cost-effective option for outdoor flooring. They come in various shapes, sizes, and colors, allowing for a range of design options. To calculate the number of pavers needed, we first need to determine the total area of the patio. The formula for the area of a rectangle is length times width, so the area of the patio is 3.2 m x 5.0 m = 16 square meters. Next, we need to determine the size of the pavers. Let's assume we use 30 cm x 30 cm pavers. To cover 1 square meter with these pavers, we will need 11 pavers (100 cm / 30 cm = 3.33 pavers per meter, and 3.33 x 3.33 = 11.11 pavers per square meter, rounded to 11). Therefore, to cover the 16 square meter patio, we will need approximately 176 pavers (11 pavers per square meter x 16 square meters = 176 pavers).

The number of cupcakes that were sold in each of the hours between 4 and 6 o’ clock is 24 cupcakes.

Since the total number of cupcakes that were sold is equal to 9 dozen cupcakes.

Total number of cupcakes = 9 * 12 = 108 cupcakes.

Since c is the number of cupcakes that were sold in each of the hours between 4 and 6 o’ clock.

We can write an equation that represents the total number of cupcakes sold as follows:

36 + 24 + c + c = 108

Solve for c:

36 + 24 + c + c = 108

36 + 24 + 2c = 108

60 + 2c = 108

2c = 108 - 60

2c = 48

c = 48/2

c = 24

Therefore, the number of cupcakes that were sold in each of the hours between 4 and 6 o’ clock is 24 cupcakes.
