We need a sample size of 98 to estimate the mean with 90% confidence and an error of ±0.25 mpg, using the given range of fuel economy for the 2016 Toyota 4Runner.

Standard deviation is a measure of the amount of variation or dispersion in a set of data. It is a statistical measure that is used to quantify the amount of variation or spread of a set of data values relative to the mean or average value of the data.

(a) Using Method 3, the Empirical Rule for a normal distribution, we know that for a normal distribution, approximately 68% of the values fall within 1 standard deviation from the mean, 95% fall within 2 standard deviations from the mean, and 99.7% fall within 3 standard deviations from the mean.

Therefore, to find the standard deviation for the given range of 17 to 22 mpg, we can use the Empirical Rule as follows:

The range between the mean and the upper limit (22 mpg) is 3 standard deviations, so the standard deviation can be estimated as (22-17)/3 = 1.6667 mpg.

Thus, the estimated standard deviation using Method 3 is 1.6667 mpg, rounded to 4 decimal places.

(b) To find the sample size required to estimate the mean with 90% confidence and an error of ±0.25 mpg, we can use the following formula:

[tex]n = (z*(E))^2[/tex]

where n is the sample size, z is the z-score corresponding to the desired confidence level (90% = 1.645), σ is the estimated standard deviation from part (a), and E is the desired margin of error (±0.25 mpg).

Substituting the values, we get:

[tex]n = (1.645*(1.6667/0.25))^2[/tex]

n ≈ 97.15

Rounding up to the nearest whole number, we get the sample size of 98.

Therefore, we need a sample size of 98 to estimate the mean with 90% confidence and an error of ±0.25 mpg, using the given range of fuel economy for the 2016 Toyota 4Runner.

To distribute -3√3 to (2 + √6), we can use the distributive property:

-3√3 (2 + √6) = (-3√3 * 2) + (-3√3 * √6)

Next, we can simplify each term using the product rule of radicals:

(-3√3 * 2) = -6√3

(-3√3 * √6) = -3√(3

Therefore, when we distribute -3√3 to (2 + √6), we get:

-3√3 (2 + √6) = -6√3 - 9√2.

The central angle of the given arc, subtending a circle with a radius of 7 cm and a length of 14 cm, is approximately 103.13 degrees.

An arc is a section of a circle's or curve's border in mathematics. It is additionally known as an open shape. The circumference, also referred to as the perimeter, is the measurement around a circular that defines its edge. Consequently, the arc is defined as the separation between any two locations along its circumference.

The angle that an arc of a circle subtends at the center is called the central angle. The central angle is measured in degrees and is formed by the radii that make up the arc.

Given:

Radius of the circle (r) = 7 cm

Length of the arc (s) = 14 cm

To find the central angle (θ) of the arc, we can use the formula:

θ = (s / r) * (180 / π)

where:

s = length of the arc

r = radius of the circle

π = pi (approximately 3.14159...)

Plugging in the given values:

θ = (14 / 7) * (180 / π)

θ = 2 * (180 / π)

θ ≈ 103.13 degrees (rounded to two decimal places)

So, the central angle of the given arc, subtending a circle with a radius of 7 cm and a length of 14 cm, is approximately 103.13 degrees.

The statement is not true, since 13 is not less than 6. Therefore, the point (3, 2) is not a solution of the linear inequality 3x + 2y < 6.

To determine if the point (3, 2) is a solution of the linear inequality 3x + 2y < 6, we substitute the values of x and y in the inequality and check if it is a true statement or not.

A linear inequality is an inequality in which the variables have a degree of one, and the inequality can be expressed as a linear equation with an inequality symbol. A linear inequality can be represented graphically as a line with a shaded region that either includes or excludes certain points in the coordinate plane.

For example, the inequality 2x + 3y > 6 is a linear inequality. To graph this inequality, we can first plot the line 2x + 3y = 6 by finding its x and y intercepts, which are (3, 0) and (0, 2), respectively. Then, we can choose a test point not on the line, such as (0, 0), and substitute its coordinates into the inequality to see if it is a solution.

3(3) + 2(2) < 6

9 + 4 < 6

Answer:

Option A) m^9.

Step-by-step explanation:

To simplify the given expression, we can use the rules of exponents which state that when we multiply powers with the same base, we can add their exponents.

So, m² ∙ m⁶ ∙ m can be simplified as:

m² × m⁶ × m = m^(2+6+1) = m^9

Therefore, the simplified form of m² ∙ m⁶ ∙ m is m^9.

To solve the equation:

1/(x+1) + 9/(x+9) = 1

First, we can simplify the equation by finding a common denominator:

((x+9)+9(x+1))/(x+1)(x+9) = 1

Simplifying the numerator, we get:

(10x+18)/(x+1)(x+9) = 1

Cross-multiplying gives:

10x+18 = (x+1)(x+9)

Expanding the right side of the equation, we get:

10x+18 = x^2+10x+9

Simplifying and rearranging gives:

x^2-9 = 0

Using the quadratic formula, we solve for x:

x = (±sqrt(81))/1

x = ±9

Therefore, the solutions to the equation are x = -9 and x = 9.

The total cost of buying three of the ABC bonds would be $334.25 + $321.50 + $55 = $710.75.

What is probability?

Probability is a measure of the likelihood of an event occurring.

To calculate the cost of buying three of the ABC bonds, we first need to determine which bond is being referred to as the "ABC bond." The table lists three bonds: A, B, and C.

Next, we need to calculate the cost of each bond, taking into account the current yield and the price at which the bond is being sold. The current yield is the annual return on the bond expressed as a percentage of the bond's current market price.

For bond A, the current yield is 7.5%, and the bond is being sold at a price of 104 and three-fourths (104.75). For bond B, the current yield is 8.4%, and the bond is being sold at a price of 100 and one-half (100.5). For bond C, the current yield is also 7.5%, and the bond is being sold at a price of 15.

To calculate the cost of buying three of the ABC bonds, we need to multiply the price of the bond by the number of bonds purchased, and then add the commission. For bond A, the cost would be (104.75 x 3) + (10 x 3) = $334.25. For bond B, the cost would be (100.5 x 3) + (10 x 3) = $321.50. For bond C, the cost would be (15 x 3) + (10 x 3) = $55.

Therefore, the total cost of buying three of the ABC bonds would be $334.25 + $321.50 + $55 = $710.75.

The length of the base with area 25/18 square meters is 5/3 meters. This answer is in its simplest form.

The height of a triangle is the length of the line segment that is drawn from the vertex of the triangle perpendicular to the base.

The area of a triangle is given by the equation

A = 1/2 * base * height.

Therefore, we can substitute the value of the area and the height of the triangle into the equation to solve for the base.

A = 1/2 * b * (5/3)

25/18 = 1/2 * b * (5/3)

We will divide left side of the equation by 5/3.

(25/18) / (5/3) = (1/2)*b

(25/18) * 3/5 = (1/2)*b

Now, we can solve for b by dividing the left side of the equation by 1/2

(5/6) / (1/2) = b

b = 5/6 * (2/1)

b = 5/3

The graph of the inequality y > 1/4x + 2 is a straight line with a slope of 1/4 passing through the point (0, 2), and the shaded area is above the line. The graph looks like a half-plane that is unbounded in the upward direction.

To graph the inequality y > 1/4x + 2, we can follow these steps:

Start by drawing the line y = 1/4x + 2. To do this, we can use the slope-intercept form of a line, which is y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is 1/4 and the y-intercept is 2. So we can plot the point (0, 2) and then use the slope to find another point on the line. The slope tells us that for every increase of 4 in x, y will increase by 1. So we can plot the point (4, 3) and draw a straight line passing through both points.

Next, we need to determine which side of the line to shade. To do this, we can pick a point not on the line and test whether it satisfies the inequality. For example, we can pick the point (0, 0) and substitute its x and y values into the inequality y > 1/4x + 2. We get 0 > 1/4(0) + 2, which simplifies to 0 > 2. Since this is false, the point (0, 0) is not a solution to the inequality, so we shade the other side of the line.

Finally, we can label the shaded area to indicate the solution set of the inequality. We can write y > 1/4x + 2 above the shaded area to show the inequality that represents the shaded region.

Therefore, the graph of the inequality y > 1/4x + 2 is a straight line with a slope of 1/4 passing through the point (0, 2), and the shaded area is above the line. The graph looks like a half-plane that is unbounded in the upward direction.

To calculate Darrius' monthly take-home pay, we first need to calculate his annual state income tax. We do this by multiplying his yearly salary by the state income tax rate:

$42,350 x 3.07% = $1,292.94

Next, we subtract the state income tax from his annual salary to get his annual net income:

$42,350 - $1,292.94 = $41,057.06

Finally, we divide his annual net income by 12 to get his monthly take-home pay:

$41,057.06 / 12 = $3,421.42

Therefore, Darrius' monthly take-home pay is $3,421.42.

What is a quadratic equation?

A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

Let's assume that Mohal's age is x. Then, Kiran's age is x + 2, since their ages are consecutive odd integers and Kiran is older than Mohal.

We are given that the sum of the square of Kiran's age and 3 times Mohal's age is 64:

(x + 2)² + 3x = 64

Expanding the left-hand side and simplifying, we get:

x² + 7x - 56 = 0

This is a quadratic equation in standard form. We can solve for x by using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

where a = 1, b = 7, and c = -56.

Plugging these values into the formula, we get:

x = (-7 ± √(7² - 4(1)(-56))) / 2(1)

x = (-7 ± √(289)) / 2

We take the positive root because x represents Mohal's age, which is a positive integer. Therefore:

x = (-7 + 17) / 2 = 5

So, Mohal is 5 years old, and Kiran is 7 years old.

To calculate the infusion rate, we need to use the formula:

Infusion rate (ml/hour) = (dose ordered * patient weight * 60) / (drug concentration * 1000)

where:

Dose ordered is the prescribed dose of the drug per unit of time (0.1 mg/kg/hr in this case).

Patient weight is the weight of the client (78 kg in this case).

Drug concentration is the concentration of the drug in the solution (25 mg/250 ml or 0.1 mg/ml in this case).

Substituting the values we have:

Infusion rate = (0.1 mg/kg/hr) * (78 kg) * 60 / (0.1 mg/ml * 1000)

Simplifying:

Infusion rate = 4.68 ml/hour

Therefore, the practical nurse should program the infusion pump to deliver 4.68 ml/hour (rounded to the nearest tenth).

Answer:

To calculate the infusion rate, we need to use the following formula:

Infusion rate (mL/hour) = Total volume (mL) x Infusion rate (mL/hour) / Time (hour)

First, let's calculate the client's infusion rate in mg/hour:

Infusion rate (mg/hour) = 0.1 mg/kg/hour x 78 kg = 7.8 mg/hour

Now, let's convert the pancuronium dose to mg/mL:

25 mg/250 mL = 0.1 mg/mL

To calculate the total volume of the infusion, we need to assume a time frame. Let's assume that the client needs the infusion for 1 hour. Then:

Total volume (mL) = Infusion rate (mg/hour) / Dose (mg/mL) = 7.8 mg/hour / 0.1 mg/mL = 78 mL/hour

Therefore, the practical nurse should program the infusion pump to deliver 78 ml/hour.
