The required cost of carpet is $1,148.

Hence option (c) is correct.

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

Cost of carpet of dimension 10 ft x 6 ft = $1230

Then cost of carpet of area 60 ft² = $1230

The cost of carpet per unit area = 1230/60

                                                      = $20.5

Area of carpet 7 ft x 8 ft =  56 ft²

Then the cost of this carpet

= 56x20.5

= 1,148

Therefore, the cost of carpet of dimension 7 ft x 8 ft = $1,148

To simplify the expression f(x-3), we need to substitute x-3 for x in the original expression f(x) = x² + 4.

So, f(x-3) = (x-3)² + 4

= x² - 6x + 9 + 4

= x² - 6x + 13

Discrete data refers to data that can only take on specific, separate values. It is a type of data that can be counted or enumerated, but not measured. In other words, the values can't be expressed as fractions or decimals between two whole numbers.

The model product, P(16), predicts the number of moose to be 3545 in 1997 and 2970 in 2009.

The odds that a happening will happen or a claim will be true is measured by probability theory, a branch od arithmetic. The probability of an item is a number between 0 but also 1, where about 0 represents how frequently the event is to occurring and 1 represents certainty. A risk is a numerical illustration of the possibility that a specific occurrence will take place. Probabilities may be expressed as percentages ranging from 0percent to 100% as well as from 0 to 1. the ratio of the number of outcomes to the proportion of occurrences in a whole set of equally plausible options that lead to a specific occurrence.

given

We'll choose x on the graph to represent the number of years since 1990 and y to represent the number of moose.

On the graph, there are two points: (4, 4290) and (8, 3850)

We can determine the slope of this line using the slope formula (m = [y2 - y1]/[x2 - x1]):

Replacement: m = (3850 - 4290)/(8 - 4)

m = -440/4 Solve the parenthesis's subtraction puzzles.

m = -110 Reduce the percentage

Since we know the line's slope, we can apply the point-slope formula (y - y1 = m[x - x1]) to determine the line's equation.

The area of the region inside both the square and the rectangle is 37 square units.

Step-by-step explanation:

The area of the region inside both the square and the rectangle can be found by subtracting the areas of the four triangles outside the square from the area of the rectangle.

The area of the rectangle is 4 * 8 = 32 square units. The area of each triangle can be found using the formula for the area of a triangle, which is (base * height) / 2. The base of each triangle is half the length of the side of the square, which is 5 / 2 = 2.5 units. The height of each triangle is the difference in height between the rectangle and the square, which is 4 - 5 = -1 unit. The area of each triangle is (2.5 * -1) / 2 = -1.25 square units. The area of the four triangles outside the square is 4 * -1.25 = -5 square units.

The area of the region inside both the square and the rectangle is 32 + 5 = 37 square units.

The p-value for the test is  0.0062

To determine the p-value for Kara's hypothesis test, we need to calculate the test statistic and then find its corresponding p-value.

Let's start by calculating the sample mean and standard deviation of the given data:

Sample mean x = (46+43+41+48+51+51+52+42+51+54+40+53+46+46+46+39+47)/17 = 46.529

Sample standard deviation (s) = 4.547

We can use these values to calculate the t-statistic for the one-sample t-test:

t = (x - μ) / (s / sqrt(n))

where μ is the hypothesized population mean (50 hours), n is the sample size (17).

t = (46.529 - 50) / (4.547 / sqrt(17)) = -3.15

Using a t-distribution table with 16 degrees of freedom (n-1), we find that the p-value for a two-tailed test with a t-statistic of -3.15 is approximately  0.0062.

Therefore, the p-value for this hypothesis test is  0.0062

Since the p-value is less than the commonly used alpha level of 0.05, we reject the null hypothesis and conclude that there is evidence to suggest that the true mean work week for engineers in start-up companies is less than 50 hours.

Answer:

You would have to buy three raffle tickets to have a chance to receive all three pieces of merchandise.

Step-by-step explanation:

Each raffle ticket gives you a chance to win one of the three pieces of marching band merchandise: T-shirt, hat, or shorts. To have a chance of winning all three pieces, you would need to buy three separate raffle tickets, each with a chance to win a different piece of merchandise. This way, you would increase your chances of receiving all three pieces through the random selection process of the raffle.

If each raffle ticket has an equal chance to win any of the three pieces of merchandise, then you would have a 33% chance of winning any one piece of merchandise with each ticket you buy. To have a greater chance of winning all three pieces, you would need to buy multiple tickets.

For example, if you buy three tickets, the chance of winning all three pieces of merchandise would be (1/3) * (1/3) * (1/3) = 1/27. This means that you have a 1 in 27 chance of winning all three pieces of merchandise with three raffle tickets.

The distribution is b) skewed.

The sum of the probabilities is: 1

In a binomial distribution, p represents the probability of success. Success in the sense that the event of interest happens. In the model presented, the probability of success p is 0.4 since we are informed that 40% of adults watch a particular television show.

The next quantity of significance in a binomial model is the number of independent trials, n.

In our case there are 6 independent trials since we are told that 6 adults were selected at random. If we let the random variable K denote the number of adults out of the 6 who watch the television show, then K is a binomial random variable with parameters;

n = 6 and p = 0.4

A binomial distribution is only symmetric when either p is 0.5 or n is large. In the presented scenario none of these conditions is met since p is 0.4 while n is just 6 which is relatively small.

Thus we conclude that the distribution is not symmetric but rather skewed.

The trigonometric functions in mathematics are real functions that relate the right-angled triangle's angle to the ratios of its two side lengths. They are extensively used in all fields of geometry-related science, including geodesy, solid mechanics, celestial mechanics, and many others.

There are six trigonometric ratios used in trigonometry: sine, cosine, tangent, secant, and cotangent. The abbreviations for these ratios are sin, cos, tan, sec, cosec(or csc), and cot. Look at the below-displayed right-angled triangle. Any two of the three sides of a right-angled triangle can be compared in terms of their respective angles using trigonometric ratios.

Given that tan θ = -1.52.

The given expression is
