Answer:

One solution, A) (2 , -1)

Step-by-step explanation:

The solution is where the two lines intersect. If the lines do not intersect, it is no solution. If the line intersects once (like in the picture), it has one solution. If it intersects more than once (x), then it will have x amount of solutions.

In this case, the intersection is at (2 , -1), therefore, A) (2 , -1) is your answer.

The equation for the proportional relationship between the number of hours Corrie works, h, and her total pay, P, can be represented as \(P = Ph\).

If we assume that Corrie's pay rate is P dollars per hour, then the equation for the proportional relationship between the number of hours Corrie works, h, and her total pay, P, can be represented as P = Ph, which simplifies to:

P = hP

Here, the P is the pay rate in dollars per hour, and h is the number of hours worked. Note that this equation is similar to the original equation e = 23h, except that the constant of proportionality has been replaced with the pay rate, P.

Full question "The proportional relationship between the number of hours Corrie works, h, and his total earnings in dollars and cents, e, can be represented by the equation e = 23h. Write an equation for the proportional relationship between the number of hours Corrie works, h, and her total pay, P."

It is possible to determine the theoretical probability of an occurrence without doing the event itself. A number cube has 6 alternative outcomes, giving each one a theoretical probability of 1 out of 6.

For example, the likelihood of drawing an ace at random is 4 out of 52 since there are 4 aces in a deck of cards. The probability of hitting a double bullseye on a regular dartboard is roughly 78 out of 100,000 because the area of the double bullseye in the center is 0.078% of the dartboard's overall area.

The likelihoods of potential possibilities are instead calculated using the frequencies of past outcomes in empirical probability. They are merely projections. The empirical chance of rolling a 4 or a 5 on the following roll is 58 out of 96 since you rolled 4s and 5s more often than any other number when you rolled the number cube.

Step-by-step explanation:

The new variance for the data is 0.35 .

In statistics and probability theory, variance is the predicted squared deviation of a stochastic process from its mean or actual values.

Dispersion, or how far apart from the mean a set of data are from one another, is measured by variance.

A few ideas that involve variance are descriptive statistics, parameter estimation, testing hypotheses, quality of fit, and Monte Carlo sampling.

Variance is a vital tool in the fields where statistical data analysis is widely used.

The standard deviation squared is a measure of the variance, which is also referred to as the second systematic of a distribution and the correlation between the random variable and itself.

We know that variance = (standard deviation)²

When the value of the data increases by 25 cents a box , then the standard deviation will remain the same as the mean will only increase and the change in mean has no effect on the SD.

Hence the variance will effectively remain the same.

therefore the new variance is 0.35

Based on the drawing obtained from the description, the location of

Manu's farm is located relatively south to Dogbe's farm.

Reasons:

The bearing of the cottage to Dogbe's farm = 200°

The distance Dogbe walks from the cottage to his farm = 5 km

The bearing of the cottage from Manu's farm = 110°

The distance Manu walks from the cottage to his farm = 3 km

Required:

The distance and between the two farms.

Solution:

Please find attached a drawing showing the position of the cottage

By cosine rule, we have;

Where;

b = The distance Dogbe walks from the cottage to his farm = 5 km

c = The distance Manu walks to his farm from the cottage = 3 km

a = The distance between the two farms = d

A = The angle between the paths to the cottage from the farms = 50°

By plugging in the values, we have;

d² = 5² + 3² - 2 × 5 × 3 × cos(50°)

d = √(5² + 3² - 2 × 5 × 3 × cos(50°)) ≈ 3.8

Required:

The bearing of Manu's farm from Dogbe's

Solution:

By sine rule, we have;

Which gives;

\(\displaystyle sin(C) = \mathbf{\frac{3 \times sin(50^{\circ})}{\sqrt{5^2 + 3^2 - 2 \times 5 \times 3 \times cos(50^{\circ})} }}\)

\(\displaystyle \angle C = arcsine \left(\frac{3 \times sin(50^{\circ})}{\sqrt{5^2 + 3^2 - 2 \times 5 \times 3 \times cos(50^{\circ})} } \right) \approx 38 ^{\circ}\)

A check or quadrangle is defined by the intersection of pairs of diagonals of a parallelogram.

A parallelogram is a quadrilateral with two pairs of parallel sides. In a parallelogram, the opposite sides are parallel and have the same length. The opposite angles of a parallelogram are equal. A parallelogram is a unique type of quadrilateral with specific characteristics.

A quadrangle or check is defined as the intersection of pairs of diagonals of a parallelogram. In other words, it is the area inside the parallelogram that is divided into four triangles, each of which shares a common vertex in the center of the parallelogram.

The diagonals of a parallelogram are the line segments that connect the opposite vertices of a parallelogram. When these diagonals intersect, they form four triangles, which are also known as the parallelogram's "sub-triangles." The point where the diagonals intersect is called the center of the parallelogram, and it divides each diagonal into two equal parts.

It could be slightly lower or higher, but we can be confident that it falls somewhere between 0.32 minutes and 1.47 minutes.

The most accurate interpretation of the given confidence interval is as follows:

We are 95% confident that the true difference in mean wait time between Facility A and Facility B falls within the range of 0.32 minutes to 1.47 minutes.

This means that if we were to repeat the study multiple times and calculate a new confidence interval each time, we would expect that approximately 95% of those intervals would contain the true difference in mean wait time between the two facilities.

Furthermore, based on the observed data and the calculated confidence interval, we can conclude that the difference in mean wait time between Facility A and Facility B is likely to be positive, with Facility B having a higher mean wait time than Facility A. However, we cannot say with certainty that the true difference is exactly within this specific range; it could be slightly lower or higher, but we can be confident that it falls somewhere between 0.32 minutes and 1.47 minutes.

The correct answer to the given question is "it is inverse."

One of the most essential characteristics of the normal distribution is that it is bell-shaped.

This implies that it is symmetrical, with the highest point at the mean or center and the curve declining on either side of the mean.

Normal distribution is a crucial concept in statistics and is widely utilized in research and decision-making processes.

It is a probability distribution that is commonly used to describe the distribution of a set of data.

The normal distribution has several characteristics that distinguish it from other probability distributions.

The normal distribution is not inverse, meaning that the tails do not approach the x-axis as they extend.

Rather,

The normal distribution has a gradual decline, with the tails diminishing in size but never reaching zero.

It is also asymptotic, which means that the tails of the distribution continue indefinitely without ever touching the x-axis, although they become increasingly small as they move away from the mean.

Normal distribution is not skewed, which means that it is symmetrical around the mean.

A skewed distribution is one in which the mean, median, and mode are not equal, indicating that one side of the curve is longer than the other.

The normal distribution's symmetry is one of its most important features since it indicates that the mean, median, and mode are all equivalent, and the data is uniformly distributed on either side of the mean. Therefore, the correct answer to the given question is "it is inverse."

X has a normal distribution, X that will give it a mean of zero and a variance , then the mean of Y = E(10+5X) = 1020

The variance is a measure of variability. It is calculated by taking the average of squared deviations from the mean. Variance tells you the degree of spread in your data set. The more spread the data, the larger the variance is in relation to the mean.

Given that,

E(x) = 30

Var(x) = 144

E(y) = ?

Var(y) = 144

Then,

E(10+5X)

To do this, we make use of the following equation

E(ax + by) = a E(x) + b E(y)

E(10+5X) = 10 E(x) + 5 E(y)

E(10+5X) = 10*30 + 5*144

E(10+5X) = 300 + 720

E(10+5X) = 1020

Therefore,

X has a normal distribution, X that will give it a mean of zero and a variance , then the mean of Y = E(10+5X) = 1020

Answer:

Use Pythagorean theorm.

a^2 + b^2 = c^2 (c is hypotenuse).

Let c = 5+b (because in the question it says the hypotenuse is one leg plus 5 more meters) ; we will solve for b and say it's the leg we don't know.

We will say A is the "other leg" we know, which is 6.
