Step-by-step explanation:

The solution means the intersection point, so in this case, it's (3, 2). The intersection point represents a value that is true for both equations, which is why it's considered the solution.

If a spherical hot air balloon inflates at a rate of 101 ft³/min.  The rate  that the radius is changing when the surface area is 20.2 ft²  is 0.

Using the volume of a spherical balloon formula

V = (4/3)πr³

Take the derivative of both sides

dV/dt = 4πr² (dr/dt)

Substituting

20.2 = 4πr²

Differentiate both sides

d/dt (20.2) = d/dt (4πr²)

0 = 8πr(dr/dt)

Solve for dr/dt:

dr/dt = 0 / (8πr)

dr/dt = 0

Therefore the rate of change of the radius (dr/dt) is 0.

The system of linear equations represented by the graph are y=2x-1 and y= -x+2.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Given that,

The coordinates on the blue line are (2, 3) and (0, -1)

The coordinates on the red line are (2, 0) and (0, 2)

Equation of a line with (2, 3) and (0, -1)

Now, m=(y₂-y₁)/(x₂-x₁)

An equation is formed of two equal expressions. The correct option is x+y=557 and Three-fifths(x)+five-sixths(y)=407.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the total number of pages in the shorter book be represented by x, and the total number of pages in the longer book be represented by y.

Given the total number of pages of the shorter book and the longer book is  557. Therefore, the equation can be written as,

x+y =557

Also, Scott reads Three-fifths of the shorter book and StartFraction 5 Over 6 EndFraction of the longer book, which is equal to 407 pages. Therefore,

The unreasonable ineffectiveness of mathematics in the natural sciences is a phrase coined by physicist Eugene Wigner in his famous 1960 essay of the same name. Wigner observed that mathematics, despite being an incredibly powerful and precise tool, often fails to fully capture or explain certain phenomena in the natural sciences.

He noted that while mathematical models can provide valuable insights and predictions, they often fall short of fully describing complex physical systems.

Wigner argued that this was an unexpected and mysterious aspect of the relationship between mathematics and the natural sciences. He suggested that perhaps the universe operates in a way that is fundamentally beyond our mathematical comprehension, or that we have yet to discover the correct mathematical language to describe it.

Despite this, Wigner acknowledged that mathematics has still been an incredibly successful and indispensable tool in the natural sciences, allowing us to make tremendous advances in fields such as physics, chemistry, and biology.

The interval of time during which the projectile's height exceeds 192 feet is t > 4. Option C.

To determine the interval of time during which the projectile's height exceeds 192 feet, we need to find the values of 't' that satisfy the condition h > 192.

The equation for the height of the projectile is h = -16t^2 + 112t.

Setting h greater than 192, we have:

-16t^2 + 112t > 192

Rearranging the equation to isolate the quadratic term, we get:

-16t^2 + 112t - 192 > 0

Now, we can solve this quadratic inequality by factoring or using the quadratic formula. However, we can simplify the process by dividing the entire inequality by 16, resulting in:

-t^2 + 7t - 12 > 0

Factoring the quadratic, we have:

-(t - 3)(t - 4) > 0

From this, we can determine the sign of the expression within each interval:

For t < 3, both factors are negative, so the expression is positive.

For 3 < t < 4, the first factor is negative, and the second factor is positive, so the expression is negative.

For t > 4, both factors are positive, so the expression is positive. Option C is correct.

Step-by-step explanation:

If they want to be 99% sure that their estimate will be within 3% of the true population percentage then the required sample size is n = 4161.

When there is no known population, the sample size can be calculated by determining the minimal sample size needed to accurately estimate proportions while taking the standard normal deviation into account.

We have been given the confidence level = c= 99%

Estimate percentage= 3%

We want to find the sample size when the true percentage is not given

Therefore Assume that true proportion = p = 0.5

Therefore the sample size is calculated as:

N= p(1-p) (zc/e) square

N = 4161

Answer:

7.0

Step-by-step explanation:

Due to its larger time frame and less sensitivity to transient variations in the data, the 200-day moving average is often smoother than the 50-day moving average.

The 200-day moving average is typically smoother than the 50-day moving average because it covers a longer period of time and is therefore less reactive to short-term fluctuations in the data. However, the choice between using a 50-day or a 200-day moving average ultimately depends on the specific data being analyzed and the desired level of sensitivity to changes in the data.

A 200-day moving average will be smoother than a 50-day moving average. The 200-day moving average considers a longer period of time, which reduces the impact of short-term fluctuations and provides a clearer overall trend. The 50-day moving average is more sensitive to recent price changes and will appear more volatile in comparison.

Yes, it is necessary to apply the finite population correction factor because the sample size (n = 70) is more than 5% of the population size (N = 500). The finite population correction factor is used to adjust the standard error when a significant proportion of the population is sampled.

Yes, it is necessary to apply the finite population correction factor when calculating the standard error of the sample mean because the population size is finite and relatively small compared to the sample size. Without applying the correction factor, the standard error would be underestimated, leading to incorrect inference about the population mean.

Londell needs to deliver newspapers for 24 weeks to have enough money to buy the bicycle.

Londell currently has $40 saved, and he needs a total of $400 to buy the bicycle. Each week, he earns $15 delivering newspapers.

To calculate the number of weeks Londell needs to work, we can set up an equation:

$40 (current savings) + $15 (weekly earnings) × (number of weeks) = $400 (total cost of the bicycle)

Simplifying the equation:

$40 + $15 = $400

Subtracting $40 from both sides of the equation:

$15 = $400 - $40

$15 = $360

Dividing both sides of the equation by $15:

= $360 / $15

≈ 24

Therefore, Londell will have to deliver newspapers for approximately 24 weeks to have enough money to buy the bicycle.
