Answer: The answer is state B because there is less variability in larger populations so estimates from samples are more accurate. The standard error of the mean is proportional to the standard deviation of the population and inversely proportional to the square root of the sample size. Since state B has a much larger population, it is more likely that our sample mean will be within $80 of $2,600 for state B than for state A.

Answer:

x = -8 + sqrt(10) and x = -8 - sqrt(10)

Step-by-step explanation:

The quadratic equation to be solved is:

2(x + 8)² + 9 = 29

First, we need to simplify the left-hand side of the equation by expanding the squared term:

2(x + 8)(x + 8) + 9 = 29

Simplifying further, we get:

2(x² + 16x + 64) + 9 = 29

Distributing the 2, we get:

2x² + 32x + 128 + 9 = 29

Combining like terms, we get:

2x² + 32x + 137 = 29

Subtracting 29 from both sides, we get:

2x² + 32x + 108 = 0

Dividing both sides by 2, we get:

x² + 16x + 54 = 0

We can solve this quadratic equation by factoring or by using the quadratic formula :

The equation presented is a quadratic equation in standard form, ax² + bx + c = 0, where a = 1, b = 16, and c = 54. To solve this equation, we can use the quadratic formula, x = (-b ± sqrt(b² - 4ac)) / 2a. Plugging in the values, we get x = (-16 ± sqrt(16² - 4(1)(54))) / 2(1) = (-16 ± sqrt(16)) / 2 or (-16 ± 2sqrt(10)) / 2. Simplifying, we get x = -8 ± sqrt(10). Therefore, the two solutions to this equation are x = -8 + sqrt(10) and x = -8 - sqrt(10).

The roots (if any) are determined by the values of x that make f(x) = 0. To find them, we solve the quadratic equation associated with the function.

A quadratic equation is an equation of the form:

ax² + bx + c = 0

where a, b, and c are constants. For a quadratic function of the form:

f(x) = ax² + bx + c

the roots are the values of x that satisfy the equation f(x) = 0. To find the roots, we set f(x) equal to zero and solve for x using the quadratic formula:

x = (-b ± √(b² - 4ac))/2a

If the discriminant (b² - 4ac) is negative, then the quadratic equation has no real roots, and the function f(x) does not intersect the x-axis. If the discriminant is zero, then the quadratic equation has one real root, and the function f(x) touches the x-axis at that point. If the discriminant is positive, then the quadratic equation has two real roots, and the function f(x) intersects the x-axis at those points.

The diameter of the balloon is increasing at a rate of approximately 0.79 ft/min when the diameter is 1.5 feet.

We can use the formula for the volume of a sphere to relate the rate of change of volume with the rate of change of diameter

V = (4/3)πr^3 = (1/6)πd^3,

where V is the volume, r is the radius, and d is the diameter.

Taking the derivative with respect to time t, we get

dV/dt = (1/2)πd^2 (dd/dt),

where dd/dt is the rate of change of diameter.

We are given that dV/dt = 2.8 ft^3/min and d = 1.5 ft, so we can solve for dd/dt

dd/dt = (2dV/dt)/(πd^2) = (2(2.8))/(π(1.5)^2) ≈ 0.79 ft/min.

Answer:

40 beads

Step-by-step explanation:

First, let's find the length of string that the beads will be on.

The string is originally 20 cm, but 2 cm is taken off each side.

So, the string that the beads will be on is only 16 cm now.

Each bead is 4 mm wide, so we have to convert the bead width to centimeters.

4/10=0.4

So each bead is 0.4 cm.

Now to find how many beads will fit, we have to divide the length by the width of the bead.

16/0.4=40

So, Mona will need 40 beads.  Hope this helps ;)

The measure of the angles formed by the lines are 30°, 30°,  150° and  150° by definition of vertically opposite angles.

When two straight lines intersect each other at some angle, say line AB intersect line CD, then the opposite angles formed by the two lines are called vertically opposite angles. A pair of vertically opposite angles are equal to each other.

There are two pairs of opposite angles formed by intersection of two straight lines.

The total sum of all the angles formed by intersection of two straight lines is 360°.

Let angle X = x° and angle Y= y° be a pair of opposite angles.

Let the other pair of opposite angles be of angle M = m° and angle N = n°.

Thus, by definition of opposite angles and sum of all angles on intersection of two lines we get,

angle X + angle Y + angle M + angle N = 360°

⇒ x° + y° + m° + n° = 360°

⇒ x° + x° + m° + m° = 360°

⇒ 2( x° + m°) = 360°

⇒ x° + m° = 180° ___ (1)

Also, the measure of one of the angles is five times the measure of another of the angles formed by the lines.

This relation can be written as,

angle X = 5 times of angle M

⇒ x° = 5m° ___(2)

Since angle X and angle M are not a pair of opposite angles but are supplementary angles as observed in equation (1).

Putting equation (2) in equation (1) we get,

5m° + m° = 180°

⇒ 6m° = 180°

⇒ m° = 30°

Thus, x° = 5(30°) = 150°

Hence the angles are 30°, 30°,  150° and  150°.

The length of the bridge is 980 feet.

Let's denote the length of the bridge as x. According to the problem, one bank of the river holds 3/7 of the bridge, which means that the other bank holds 4/7 of the bridge.

Therefore, we can write the following equation:

3/7 x + 1400 + 4/7 x = x

Simplifying this equation, we get:

6/7 x + 1400 = x

Subtracting 6/7 x from both sides, we get:

1/7 x + 1400 = 0

Subtracting 1400 from both sides, we get:

1/7 x = -1400

Multiplying both sides by 7, we get:

x = -9800

Since the length of the bridge cannot be negative, we need to discard this solution. Therefore, the only valid solution is:

x = 980

So the length of the bridge is 980 feet.

Answer: x=0 and x=-9

Step-by-step explanation:

Hence, it will take 2.6 hours for the two trains to be 520 miles apart.

Distance is a numerical or occasionally  qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria.

In everyday use and in kinematics, the speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity..

The two trains are moving  away from each other,

so we can  add their speeds to get their relative speed:

relative speed = 95 mph + 105 mph = 200 mph

Now ,we determine  the time it takes for the trains to be 520 miles apart,

so we can use the formula:

distance = speed × time

let t be the time  it takes for the trains to be 520 miles apart.

Then we get,

520 = 200 × t

Solving for t, we get:

t = [tex]\frac{520}{200}[/tex]

t = 2.6 hours

Therefore, it will take 2.6 hours for the two trains to be 520 miles apart.

Answer: Bret spent $52.92 on the lunch, including tax and tip.

Step-by-step explanation:

Given:

The bill before tax = $42

Sales tax = 6%

Tip = 20% before tax

To find:The total amount of money Bret spent

Solution: Calculate the sales tax:

Sales tax = 0.06 * $42 = $2.52

Calculate the total bill, including tax:

Total bill = $42 + $2.52 = $44.52

Calculate the bill before tax, based on which the tip is calculated:

Bill before tax = $44.52 - $2.52 = $42

Calculate the tip amount:

Tip = 0.2 * $42 = $8.40

Calculate the total amount spent by Bret:

Total spent = $44.52 + $8.40 = $52.92

Therefore, Bret spent $52.92 on the lunch, including tax and tip.

Answer:

Explanation:

The difference between -5 and -1 is 4 and the difference between-3 and -3 is 0.

The solutions to the equation x² + 10x + 22 = 13 are: x = -5 ± 4

To rewrite the equation by completing the square, we need to isolate the constant term on one side and group the x-terms together. Starting with:

x² + 10x + 22 = 13

Subtracting 13 from both sides:

x² + 10x + 9 = 0

Next, we add and subtract the square of half of the coefficient of x (which is 5 in this case) to complete the square:

x² + 10x + 25 - 25 + 9 = 0

x² + 10x + 25  - 16 = 0

Factor the perfect square trinomial:

(x + 5)² - 16 = 0

Now that we have rewritten the equation in the form (x + c)² = d, we can solve for x by taking the square root of both sides:

(x + 5)² - 16 = 0

Taking the square root of both sides and solving for x, we get:

x + 5 = ±4

So, we have

x = -5 ± 4

So the solutions to the equation are:

x = -5 + 4 = -1

x = -5 - 4 = -9

Therefore, the answer is x = -5 ± 4.

In systems design, objects are used to represent real-world entities that are relevant to the system being developed. These objects have attributes that describe their characteristics or properties, which are used to identify and manipulate them within the system. System analysts define these attributes during the systems design process to ensure that the system meets the desired functional requirements.

For example, in a library system, a book object may have attributes such as title, author, publisher, and ISBN. Defining these attributes helps ensure that the system can properly manage and retrieve books as needed.

In 2010, Haiti was hit by a devastating earthquake, which registered at 7.0 on the Richter scale. The largest recorded earthquake since 1900 occurred in 1960 in Valdivia, Chile, and registered at 9.5 on the Richter scale. About 316 times greater was the intensity of the Chilean earthquake.

Hence, the correct option is D.

The Richter scale is a logarithmic scale that measures the magnitude of an earthquake. Each increase of one on the Richter scale represents a tenfold increase in the amplitude of the seismic waves.

To find out how many times greater the intensity of the Chilean earthquake was compared to the Haitian earthquake, we will have to find the difference in magnitude between the two earthquakes.

9.5 - 7.0 = 2.5

Since each increase of one on the Richter scale represents a tenfold increase in the amplitude of the seismic waves, a 2.5 increase represents

10^(2.5) = 316.2

Hence, the intensity of the Chilean earthquake was about 316 times greater than the intensity of the Haitian earthquake.

What is rotation of axis?

Rotation of axes is a transformation in which the coordinate axes are rotated by a certain angle with respect to the original axes. This transformation can be used to simplify the equations of curves and to make it easier to solve problems involving them. The rotation is usually done by finding the angle of rotation, which is the angle between the original x-axis and the new x-axis. The formulae for converting coordinates from the old system to the new system can then be applied.

In the given problem, we are given that triangle PQR is located in the xy-plane with coordinates of Q being (2,-3). The task is to find the coordinates of Q' when triangle PQR is rotated 180 degrees clockwise about the origin and then reflected across the y-axis to produce triangle P'Q'R'.

To start, we apply the 180 degree clockwise rotation about the origin transformation rule to the coordinates of Q (2,-3) which gives us (-2,3).

Next, we reflect the point (-2,3) across the y-axis. Reflecting across the y-axis involves changing the sign of the x-coordinate while leaving the y-coordinate unchanged. Applying this rule,

Hence, we get the coordinates of Q' as (2,3) after rotation of the triangle.

Step-by-step explanation:

The probability that the appliance will work at least six years without requiring repairs is 0.2231 or 22.31%.

To find the probability that the appliance will work at least six years without requiring repairs, we need to consider the exponential distribution and the given average repair time. Given that the appliance requires repairs once every four years on average, the rate parameter (λ) for the exponential distribution is 1/4, or 0.25.

Here we want to find the probability that the appliance will work at least six years without requiring repairs, which can be represented as [tex]P(X ≥ 6)[/tex], where X is the time between repairs. Using the complementary probability, we can rewrite this as [tex]P(X ≥ 6) = 1 - P(X < 6)[/tex]

The cumulative distribution function (CDF) of the exponential distribution is given by

[tex]F(x) = 1 - e^{(-λx)}[/tex]

Now, we can plug in the values:

[tex]P(X ≥ 6) = 1 - F(6) \\ P(X ≥ 6) = 1 - (1 - e^{(-0.25 \times 6)}) \\ P(X ≥ 6) = 1 - (1 - e^{(-1.5)}) \\ P(X ≥ 6) = e^{(-1.5)}[/tex]

Therefore, the probability that the appliance will work at least six years without requiring repairs is approximately 0.2231 or 22.31%.
