The price that Maura sell each scarf would be =$33. Maura sells each scarf for $33. That is option A.

To calculate the amount of money that Maura spends on each scarf the following is carried out.

The amount of money that she spends on the scarf material = $5.50

The percentage selling price of each scarf = 600% of $5.50

That is ;

= 600/100 × 5.50/1

= 3300/100

= $33.

Therefore, each price that is sold by Maura would probably cost a total of $33.

A positive association on a scatter plot indicates that as the value of one variable increases, the value of the other variable also tends to increase. In other words, when the values of two variables increase together, they have a positive relationship.

For example, if we create a scatter plot of temperature and number of clothing people wear, a positive association would mean that as the temperature increases, people tend to wear more clothing.

This is because higher temperatures lead to increased discomfort, which in turn leads people to wear more clothing to stay comfortable.

Similarly, if we create a scatter plot of time and money earned, a positive association would mean that as the amount of time spent working increases, the amount of money earned also tends to increase.

This is because more time spent working often leads to more opportunities to earn money, through increased productivity or more hours worked.

Answer:

Step-by-step explanation:

Answer by using the Pythagorean Thereom where the diagonal is your C.

The work done by the vector field F over the curve, in the direction of increasing t, is 4/3 units. This is calculated by evaluating the line integral of F dot dr along the curve defined by r(t) = t^8i + t^7i + t^2k, where t ranges from 0 to 1. The result of the calculation is 4/3.

To compute the work done by the vector field F over the curve in the direction of increasing t, we need to evaluate the line integral of F dot dr along the given curve.

The vector field F is given as F = i + j + k.

The curve is defined by r(t) = t^8i + t^7i + t^2k, where t ranges from 0 to 1.

To calculate the line integral, we need to parameterize the curve and then compute F dot dr. Parameterizing the curve gives us r(t) = ti + ti + t^2k.

Now, we calculate F dot dr:

F dot dr = (i + j + k) dot (ri + ri + t^2k)

        = i dot (ti) + j dot (ti) + k dot (t^2k)

        = t + t + t^2

Next, we integrate F dot dr over the interval [0, 1]:

∫[0,1] (t + t + t^2) dt

= ∫[0,1] (2t + t^2) dt

= [t^2 + (1/3)t^3] evaluated from 0 to 1

= (1^2 + (1/3)(1^3)) - (0^2 + (1/3)(0^3))

= 1 + 1/3

= 4/3

Therefore, the work done by F over the curve in the direction of increasing t is 4/3 units.

The percentage of tires that will have a life of 45,000 to 55,000 miles is  68.27%. So the correct option is 68.27%.

To find the percentage of tires that will have a life of 45,000 to 55,000 miles, we can use the concept of the normal distribution.

First, we calculate the z-scores for both values using the formula:
z = (x - mean) / standard deviation

For 45,000 miles:
z1 = (45,000 - 50,000) / 5,000 = -1

For 55,000 miles:
z2 = (55,000 - 50,000) / 5,000 = 1

Next, we look up the corresponding values in the standard normal distribution table. The table will provide the proportion of data within a certain range of z-scores.

The percentage of tires with a life between 45,000 and 55,000 miles is the difference between the cumulative probabilities for z2 and z1.

Looking at the standard normal distribution table, the cumulative probability for z = -1 is 0.1587, and the cumulative probability for z = 1 is 0.8413.

Therefore, the percentage of tires that will have a life of 45,000 to 55,000 miles is:
0.8413 - 0.1587 = 0.6826

Converting this to a percentage, we get:
0.6826 * 100 = 68.26%

So the correct answer is 68.27%.

The correct graph that models this exponential decay would show a decreasing trend as x (the number of years) increases. we need to consider the information given regarding its decrease in value.

The piece of machinery decreases in value by 22.5% each year. This means that its value after one year is \(100\% - 22.5\% = 77.5\%\) of its original value. In other words, its value is 0.775 times its original value.

To model the value of the machinery after x years, we need to consider the exponential decay function. The general form of an exponential decay function is:

y = \(a(1 - r)^x\)

Where:

- y represents the value after x years.

- a represents the initial value.

- r represents the decay rate (expressed as a decimal).

In this case, the initial value (a) is $150,000 and the decay rate (r) is 22.5% or 0.225.

Therefore, the equation representing the value of the piece of machinery after x years would be:

y = \(\$150,000 * (1 - 0.225)^x\)

Simplifying the equation further, we have:

y = \(\$150,000 * (0.775)^x\)

From this equation, we can see that the value of the machinery decreases exponentially over time. The correct graph that models this exponential decay would show a decreasing trend as x (the number of years) increases.

The probability of randomly selecting 3 or more drivers out of 11 on a particular street who were involved in a car accident last year is approximately 0.025.

In a binomial distribution, the probability of success (being involved in a car accident) is denoted by p, and the number of trials (drivers selected) is denoted by n. In this case, p = 0.06 and n = 11.

To find the probability of getting 3 or more drivers who were involved in a car accident, we need to calculate the probabilities for each possible outcome (3, 4, 5, ..., 11) and sum them up.

Using the binomial probability formula, the probability of exactly x successes out of n trials is given by P(X = x) = C(n, x) * p^x * (1-p)^(n-x), where C(n, x) represents the binomial coefficient.

Calculating the probabilities for x = 3, 4, 5, ..., 11 and summing them up, we find that the probability of getting 3 or more drivers involved in a car accident is approximately 0.978, rounded to three decimal places.

Therefore, the correct answer is 0.978.

Answer:

3753.20 ft

Step-by-step explanation:

tan 80° = 3400 ft/x

x = 599.51 ft = distance at ground level from point directly below mountain peek to edge of mountain.

599.51 ft + 990 ft = 1589.51 ft = horizontal distance at ground level from where cable is attached to the ground to the center of the mountain. This is a leg of a right triangle.

3400 ft is another leg of a right triangle.

(1589.51 ft)² + (3400 ft)² = y²

The hypotenuse, y, is the length of the cable.

y = 3753.20 ft

The coefficient of variation (CV) is a measure of relative variability and is calculated by dividing the standard deviation by the mean, and then multiplying by 100 to express it as a percentage.

In this case, the mean weight is 340 grams, and the standard deviation is 5.2 grams.

CV = (Standard Deviation / Mean) * 100

CV = (5.2 / 340) * 100

CV ≈ 1.53%

The perimeter is indeed 26 feet, which means they have used all the extra fencing.

Let's start by assuming that the length and width of the garden patch are whole numbers of feet, since we are asked to use only whole numbers.

Let's call the length of the garden patch "L" and the width "W".

We know that Liam has 26 feet of fencing left over. This fencing will be used to make the perimeter of the garden patch, which is given by:

Perimeter = 2L + 2W

We can substitute the value of the perimeter with the amount of fencing that Liam has:

26 = 2L + 2W

Simplifying this equation, we get:

13 = L + W

Since we want to use all the extra fencing, we know that the perimeter of the garden patch must be 26 feet. We can use this information to write another equation:

Perimeter = 2L + 2W = 26

We can substitute the value of 13 for L + W in this equation:

2L + 2W = 26

2L + 2(13-L) = 26

2L + 26 - 2L = 26

26 = 26

This equation is true, which means that our assumption that L and W are whole numbers is correct.

Therefore, the dimensions of the garden patch that Liam and his brother can make for their sister are 6 feet by 7 feet.

To check, we can calculate the perimeter:

Perimeter = 2L + 2W = 2(6) + 2(7) = 12 + 14 = 26

So the perimeter is indeed 26 feet, which means they have used all the extra fencing.
