The probability that a score will have a value between X = 100 and X = 130 is 0.4332. (option b)

To find the probability of a score being between 100 and 130, we need to calculate the area under the normal curve between those two values. Since we know the mean and standard deviation of the distribution, we can standardize the values of 100 and 130 using the z-score formula:

z = (X - μ) / σ

Where X is the score we are interested in, μ is the mean of the distribution, and σ is the standard deviation.

For X = 100, the z-score is:

z = (100 - 100) / 20 = 0

For X = 130, the z-score is:

z = (130 - 100) / 20 = 1.5

Now, we need to find the probability of a z-score being between 0 and 1.5. We can use a standard normal distribution table or calculator to look up this probability. The table or calculator will give us the probability of a z-score being less than 1.5, which we can then subtract from the probability of a z-score being less than 0 to get the probability of a z-score being between 0 and 1.5.

Using a standard normal distribution table or calculator, we find that the probability of a z-score being less than 0 is 0.5. The probability of a z-score being less than 1.5 is 0.9332. Therefore, the probability of a z-score being between 0 and 1.5 is:

P(0 ≤ z ≤ 1.5) = P(z ≤ 1.5) - P(z < 0) = 0.9332 - 0.5 = 0.4332

Therefore, the answer choice that best matches this probability is p = 0.4332.

Hence the correct option is (b).

The ordered pair (x, y) = (3/5, 1/2) satisfies both equations in the given system, making it the solution.

The solution to the given system of linear equations is the ordered pair (x, y) = (3/5, 1/2). This means that when x is equal to 3/5 and y is equal to 1/2, both equations are satisfied simultaneously.

In the first equation, One-half x minus three-fourths y equals 11/60.

By substituting x = 3/5 and y = 1/2 into this equation, we have (1/2)(3/5) - (3/4)(1/2) = 11/60, which simplifies to 3/10 - 3/8 = 11/60. By further simplifying, we get 24/80 - 30/80 = 11/60, which is true since both sides are equal to 11/60.

Similarly, in the second equation, Two-fifths x plus one-sixth y equals 3/10.

Substituting x = 3/5 and y = 1/2, we have (2/5)(3/5) + (1/6)(1/2) = 3/10, which simplifies to 6/25 + 1/12 = 3/10.

By finding a common denominator and simplifying, we get 144/600 + 50/600 = 180/600, which is also equal to 3/10.

Thus, the ordered pair (x, y) = (3/5, 1/2) satisfies both equations in the given system, making it the solution.

The abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

Given the equation x^2 = 2y.

The coordinates of the point are (4,1).We have to find the abscissa on the curve that is nearest to this point.So, let's solve this question:

To find the abscissa on the curve x2 = 2y which is nearest to the point (4,1), we need to apply the distance formula.In terms of x, the formula for the distance between a point on the curve and (4,1) can be written as:√[(x - 4)^2 + (y - 1)^2]But since x^2 = 2y, we can substitute 2x^2 for y:√[(x - 4)^2 + (2x^2 - 1)^2].

Now we need to find the value of x that will minimize this expression.

We can do this by finding the critical point of the function: f(x) = √[(x - 4)^2 + (2x^2 - 1)^2]To do this, we take the derivative of f(x) and set it equal to zero: f '(x) = (x - 4) / √[(x - 4)^2 + (2x^2 - 1)^2] + 4x(2x^2 - 1) / √[(x - 4)^2 + (2x^2 - 1)^2] = 0.

Now we can solve for x by simplifying this equation: (x - 4) + 4x(2x^2 - 1) = 0x - 4 + 8x^3 - 4x = 0x (8x^2 - 3) = 4x = √(3/8)The abscissa on the curve x^2 = 2y that is nearest to the point (4,1) is x = √(3/8).T

he main answer is that the abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

The abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

Based on the polynomial function, a. the weekly income is $14,625. b. 3 plants must be sold to avoid a deficit.

Polynomial functions refer to a expressions that may contain variables of varying degrees, non-zero leading coefficients, positive exponents, and constants. A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc. In the given case, the weekly income is modelled by the polynomial function P(x) = x^2 + 2x - 15 where x represents the number of plants sold.

a. If x =120 plants, the weekly income

P(120) = (120)^2 + 2(120) – 15

P(120) = 14,400 + 240 – 15

P(120) = 14,625

Hence, the weekly income is $14,625.

b. The number of plants that should be sold in a week to avoid deficit such that weekly income does not fall below zero can be determined by P(x) = 0 and solving for x.

P(x) =x^2 + 2x – 15 = 0

x^2 + 2x – 15 = 0

x^2 + 5x – 3x – 15 = 0

x(x + 5) -3(x + 5) = 0

(x – 3)(x + 5) = 0

x = 3 or -5

As the number of plants cannot be negative, the number of plants that must be sold is 3 to avoid deficit.

Subway ridership data can reveal useful patterns through calculations with multiple operators, informing decisions about infrastructure and scheduling to better serve riders' needs.

The subway ridership dataset can reveal a wealth of information through calculations with multiple operators. One such calculation is the average increase or decrease in ridership during specific time intervals. By comparing ridership during peak and off-peak hours or weekdays versus weekends, it is possible to determine when the subway system is busiest and when it is underutilized.

Another useful calculation is the average percentage change in ridership between different stations or subway lines. This can help identify the most popular stations or lines and can inform decisions about where to allocate resources and infrastructure improvements.

Additionally, it is possible to explore the correlation between ridership and other factors such as weather, events, or holidays. By analyzing how ridership fluctuates in response to external factors, transportation planners can adjust schedules and routes to better serve the needs of riders.

Calculations with multiple operators can also reveal patterns in ridership based on time of year or day of the week. By analyzing the average change in ridership on different days or months, transportation planners can make informed decisions about scheduling and staffing.

Finally, regression analysis can be used to identify the overall trend in ridership over time. By examining long-term ridership trends, transportation planners can identify areas for improvement and plan for future infrastructure projects to better meet the needs of subway riders.

The minimum velocity required for the particle to hit the target is \($$ v_0 = \sqrt{\frac{14.0^4 - 10 \times 14.0^2}{14.0^2 - 10}} \sin 30.0^{o} = 10.694 \ m/s $$\).

The basic concept to solve this problem is using the equation of motion.

In this case, we need to solve for the magnitude of velocity given the initial height, angle and the target location.

To solve this, we can use the equation of motion:

\($$ y = y_0 + v_{0y}t + \frac{1}{2}at^2 $$\)

Here, y = final position; y₀ = initial position; \($v_{0y}$\) = initial velocity; a = acceleration due to gravity; and t = elapsed time.

We already know the initial position and the target position. So, the equation reduces to:

\($$ 14.0 - 4 = v_{0y}t - 4.9t^2 $$\)

Assuming t is the time taken to reach the target and a is the acceleration due to gravity, we can solve for \($v_{0y}$\):

\($$ \begin{align}v_{0y}t & = 10 + 4.9t^2 \\v_{0y} & = \frac{10 + 4.9t^2}{t} \end{align} $$\)

Now, we can solve for t using the kinematic equation for the angle of projection:

\($$ \begin{align}tan\theta & = \frac{v_{0y}}{{v_0}x} \\\therefore \ v_{0}x & = \frac{v_{0y}}{tan\theta}\end{align} $$\)

Here, \($v_0 = \sqrt{v_{0x}^2 + v_{0y}^2}$\) is the magnitude of the initial velocity.

Substituting values, we get: \($$ v_0 = \sqrt{\frac{10 + 4.9t^2}{t}^2 + v_{0y}^2} $$\)

Now, we need to solve for t. Since we know that \($v_0 = 14.0 \ m/s$\), we can solve this equation to get:

\($$ t = \frac{10 + v_{0y}^2}{14.0^2 - v_{0y}^2} $$\)

Substituting this value into our equation for \($v_{0y}$\) gives us: \($$ v_{0y} = \sqrt{\frac{14.0^4 - 10 \times 14.0^2}{14.0^2 - 10}} $$\)

Therefore, the minimum velocity required for the particle to hit the target is \($$ v_0 = \sqrt{\frac{14.0^4 - 10 \times 14.0^2}{14.0^2 - 10}} \sin 30.0^{o} = 10.694 \ m/s $$\).
