Find the radius of a circle with a circumference of 49 yards

Answer:

x = 20

y = 100

Step-by-step explanation:

To figure out x do this.

3x + 2x = 7x - 40 (collect like terms)

5x = 7x -40 (subtract 7x on both sides)

-2x = -40 (divide by -2 on both sides)

x = 20

Plug in to get y

Since 7x - 40 and y are vertical they equal the same amount

7(20) - 40 = y (multiply 7 by 20)

140 - 40 = y (collect like terms)

100 = y

Answer:24 nails

Step-by-step

The number of paths will be 1248072.

You must move 24 times, up 13 times, and right 11 times.

Consider placing a 13 up and 11 right order.

24 objects can be ordered in 24 different ways.

Both the sequence of the ups and the sequence of the rights are irrelevant.

Because there are 13 possible orders for the ups, you must divide by 13.

Because there are 11 different ways to number rights, you must also divide by 11.

So, The number of paths = 24! / (13! × 11!) = 1248072.

The  values of x will f(x) > 0 for x < 0, and f(x) < 0 for -6 < x < 0 and x > -6.

To determine the values of x for which f(x) > 0, we need to find the intervals where the function is positive. Let's analyze the function f(x) = x*-x³-6x².

First, let's factor out an x from the expression to simplify it: f(x) = x(-x² - 6x).

Now, we can observe that if x = 0, the entire expression becomes 0, so f(x) = 0.

Next, we analyze the signs of the factors:

1. For x < 0, both x and (-x² - 6x) are negative, resulting in a positive product. Hence, f(x) > 0 in this range.

2. For -6 < x < 0, x is negative, but (-x² - 6x) is positive, resulting in a negative product. Therefore, f(x) < 0 in this range.

3. For x > -6, both x and (-x² - 6x) are positive, resulting in a negative product. Thus, f(x) < 0 in this range.

Find the common denominator to get 306/9 + -2/9

304/9 aka 33 7/9

To determine a formula for the n-th term of an arithmetic sequence, we need to find the common difference (d) first.

The common difference is the constant value that is added or subtracted to each term to get to the next term.

In this case, we can find the common difference by subtracting the fourth term from the seventh term:

d = a₇ - a₄

d = 31 - 19

d = 12

Now that we have the common difference, we can use it to find the formula for the n-th term of the arithmetic sequence. The formula is given by:

aₙ = a₁ + (n - 1)d

In this formula, aₙ represents the n-th term, a₁ represents the first term, n represents the position of the term, and d represents the common difference.

Since we don't have the first term (a₁) given in the problem, we can find it by substituting the known values for a₄ and d:

a₄ = a₁ + (4 - 1)d

19 = a₁ + 3(12)

19 = a₁ + 36

a₁ = 19 - 36

a₁ = -17

Now we can substitute the values of a₁ and d into the formula to get the final formula for the n-th term:

aₙ = -17 + (n - 1)(12)

Therefore, the formula for the n-th term (aₙ) of the given arithmetic sequence is aₙ = -17 + 12(n - 1).

(a) The equation of the least-squares regression line that describes the relationship between the distance traveled in miles (x) and the pounds of fuel consumed (y) is given by: y = -4702.64 + 21.282x
(b) If the plot shows a random scatter, it indicates that the linear regression model is appropriate.
(c) The y-intercept in the context of the problem is -4702.64, which represents the predicted pounds of fuel consumed when the distance traveled is zero miles.

(a) The equation of the least-squares regression line for predicting the pounds of fuel consumed based on the distance traveled in miles is:

Fuel Consumed (lbs) = -4702.64 + 21.282 Distance Travelled (miles)

where Fuel Consumed and Distance Travelled are the variables used in the equation.

(b) Based on the residual plot, it is appropriate to use the linear regression equation to make predictions. The plot shows that the residuals are randomly scattered around the horizontal line at zero, indicating that there is no pattern or trend in the residuals. This suggests that the linear regression model is a good fit for the data and that the assumptions of linearity and constant variance are not violated.

(c) The y-intercept (-4702.64) represents the estimated pounds of fuel consumed when the distance traveled is zero. However, this value is not statistically meaningful in the context of the problem, as passenger aircraft cannot consume fuel if they do not travel any distance. Therefore, the y-intercept should not be interpreted in this case. The p-value for the intercept is 0.022, which is less than 0.05, indicating that the y-intercept is statistically significant. However, it may not be practically meaningful or interpretable in this context.

The probability that x=0 in a Poisson distribution with µ = 0.3 is approximately 0.7408.

In a Poisson distribution, the probability mass function (PMF) is given by P(x; µ) = (e^(-µ) * µ^x) / x!, where x is the number of events occurring, and µ is the average rate of events.

To find the probability that x=0, we substitute x=0 into the PMF formula:

P(0; 0.3) = (e^(-0.3) * 0.3^0) / 0!

Since any number raised to the power of 0 is 1 and 0! is 1, the equation simplifies to:

P(0; 0.3) = e^(-0.3)

Using a calculator, we find that e^(-0.3) is approximately 0.7408.

The probability that x=0 in a Poisson distribution with µ = 0.3 is approximately 0.7408. This means that there is a 74.08% chance of observing no events when the average rate of events is 0.3.

Significant zeros are zeros that contribute to the precision of a number, while nonsignificant zeros are placeholders or indicate the magnitude of a number.

Significant zeros are zeros that are considered significant and contribute to the precision of a number. They are located between nonzero digits or at the end of a number with a decimal point.

For example:

In the number 4,503, the zeros between 4 and 3 are significant.

In the number 0.00856, the zeros after the decimal point and before the 8 are significant.

Nonsignificant zeros, on the other hand, are zeros that do not contribute to the precision of a number and are used for placeholders or to indicate the magnitude of a number. They are typically located at the beginning or end of a number without a decimal point. Examples include:

In the number 0420, the zero at the beginning is nonsignificant.

In the number 0.003, the zeros before the decimal point is nonsignificant and serve as placeholders.

To calculate the cost using data from watts produced and watts per unit cost, you can follow these steps:

Determine the total watts produced: Multiply the watts produced by the number of units. Total Watts = Watts Produced × Number of Units

Calculate the cost per unit of electricity: Divide the total watts by the watts per unit cost. Cost per Unit = Total Watts / Watts per Unit Cost

Calculate the total cost: Multiply the cost per unit by the number of units. Total Cost = Cost per Unit × Number of Units

Here's an example to illustrate the calculation:

Let's say you have 10 solar panels, and each panel produces 200 watts. The cost per unit of electricity is $0.15 per watt.

Total Watts = 200 watts/panel × 10 panels = 2000 watts

Cost per Unit = 2000 watts / $0.15 per watt = $13.33 per unit

Total Cost = $13.33 per unit × 10 units = $133.33

Therefore, the total cost of electricity generated by the 10 solar panels would be $133.33.

By multiplying the watts produced by the number of units and dividing it by the watts per unit cost, you can determine the cost per unit. Multiplying the cost per unit by the number of units gives you the total cost.

Cost of Senior Citizen Ticket: $15

Cost of Student Ticket: $3

Step-by-step explanation:

Let the price of a senior citizen ticket be s.

Let the price of a student ticket be t.

Day 1:

s + 12t = 51

Day 2:

5s + 6t = 93

The system of equations is:

s + 12t = 51

5s + 6t = 93

Let's use the substitution method to solve it. Solve the first equation for s.

s = 51 - 12t

Now substitute s in the second equation with 51 - 12t.

5s + 6t = 93

5(51 - 12t) + 6t = 93

255 - 60t + 6t = 93

Subtract 255 from both sides. Combine -60t and 6t.

-54t = -162

Divide both sides by -54.

t = 3

Now substitute 3 for t in the equation

s = 51 - 12t

s = 51 - 12(3)

s = 51 - 36

s = 15

A line up for tickets to a local concert is normally distributed with average waiting time of 25 m a standard deviation of 4 minutes, 6.68% of people in line waited for more than 31. Using the concept of probability we get -

The area of mathematics known as probability focuses with numerical figures as to how often it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an occurrence, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Waiting time for tickets for a concert ~ N(25,4)

P(X > 31) = P( Z > (31 -25)/4) = P(Z > 1.5) = 1 - P( Z < 1.5) = 1 - 0.9332 = 0.0668

From the concept of Z-table we find the value of (Z < 1.5) is = 0.9332

a. The space creatures are most likely employed in a base other than base 10. The values of log 10, log 100, and log 1000 do not match the expected values for base 10, which should be 1, 2, and 3, respectively. Instead, the values given indicate that the base is slightly less than ten, because log 10 is less than one, log 100 is less than two, and log 1000 is less than three.

To be more specific, using the calculator's approximation, we can use the change of base formula to find the value of log base b for each of these numbers:

log base b of 10 = log 10 / log b ≈ 0.926628408

log base b of 100 = log 100 / log b ≈ 1.853256816

log base b of 1000 = log 1000 / log b ≈ 2.779885224

By dividing the known values of log 10, log 100, and log 1000, we can find log b:

0.473606797 log b = log 1000 / log 100

As a result, the space creatures are most likely based on 9.526.
