The cost equation is:

This cost has to be between 4000 and 11,000. Thus, we can write:

We can solve for the range of S with a little algebra, shown below:

The best interpretation of a 90% confidence interval is that if we were to take 1000 repeated samples of the same size and compute the confidence interval for each sample, approximately 950 of these intervals would contain the true population mean, while approximately 50 would not.

A confidence interval is a range of values within which we are confident that the population parameter (such as the mean) lies. The confidence level refers to the percentage of intervals, computed from repeated samples, that would include the true population parameter.

A 90% confidence interval means that we are 90% confident that the true population parameter falls within the computed interval. Therefore, if we were to take 1000 repeated samples and compute the confidence interval for each sample, we would expect approximately 900 of these intervals to contain the true population parameter (since 90% of the intervals would be expected to contain the true parameter), while approximately 100 intervals would not contain the true parameter.

Answer:

The distance to Jackie's friend house is 15 miles

Step-by-step explanation:

The given parameters are outlined as follows;

1) The speed with which Jackie's dad drove her to her friends house = 30 mph

2) The speed Jackie's fiend mom drove her back home on the same route = 25 mph

The time it takes Jackie's friend mom to drive her back home = 6 minutes + The time it took Jackie's dad drove her to her friends house

Let the time, in minutes, it took Jackie's dad drove her to her friends house = t

Therefore;

The time it takes Jackie's friend mom to drive her back home = 6 + t

We have that speed = Distance/Time

∴ For Jackie's friend mom, her speed of 25 mph = (The distance of Jackie's friend house)/(6 + t)

Which gives;

The distance of Jackie's friend house = 25 × (6 + t)

Similarly, for Jackie's dad, his speed of 25 mph = (The distance of Jackie's friend house)/t

Which gives;

The distance of Jackie's friend house = 30 × t

By substitution, we have;

The distance of Jackie's friend house = 25 × (6 + t) = 30 × t

By the distributive property, we have;

150 + 25·t = 30·t

150 = 30·t - 25·t = 5·t

150 = 5·t

t = 150/5 = 30 minutes

t = 30 = 0.5 Hours

Using the equation for the distance to Jackie's friend house derived with the speed of motion of Jackie's dad, we have

The distance to Jackie's friend house = 30 × t = 30 mi/h × 0.5 h = 15 mi

The distance to Jackie's friend house = 15 miles

Similarly, from the equation derived from the speed of motion of Jackie's friend mom, we have;

The distance to Jackie's friend house = 25 × (6 + t) = 25 × (6 + 30)

The distance to Jackie's friend house = 25 mph × 36 minutes

The distance to Jackie's friend house = 25 miles per hour × 0.6 hours = 15 miles

The distance to Jackie's friend house = 15 miles.

Step-by-step explanation:

The price of each pound of tuna appears to be the same.

{ 1 pond of tuna = $5 }

Predicted price for 10 pounds of tuna = $50

I think this is the answer.

Answer:

The price for each pound of tuna is the same. Each pound costs $5. For 10 lbs of tuna, it would be $50.

Step-by-step explanation:

For these kind of questions, you can either find the pattern in the information given or you find the unit price.

Pattern: Check the numbers to see if there are any patterns happening. 3 mutlpiled by 5 gets you 15, 7 muliplied by 5 gets you 35, and 9 multipled by 5 gets you 45.

Unit Price: You would need to find the price for one item, or in this case, one pound. If 3 lbs is $15 dollars you would do 15/3, 15 divided by 3/total price divided by pounds, so you would get $5. You can also change the denominator to 1 and to do this you would divide the 3 by 3 to get 1 and what you do to the bottom, you do to the top so you also divide 15 by 3 and you would get 5. In conclusion, 5/1 which is 5 dollars for one pound.

\(\frac{15}{3\\}\) > \(\frac{?}{1}\)>\(\frac{5}{1}\)

The arrows represent the number it goes in btw. I'm not too good with explaining things so let me know if you need clarifications on anything and I also personally recommend the unit price method since it isn't easy to spot a pattern with harder questions. Tell me if I'm wrong please so I can go back and look:)

Answer:

231.78 lbs

Step-by-step explanation:

total amount of cementis needed= volume of form

volume of form in ft³= length × depth × height

                        = 35.5/12 × 20/12 × 6/12

                           = 2.465ft³

density of cement= 94.01651 lb/ft³

mass of cement= density × volume

                          = 2.465 × 94.01651

                         = 231.78lb

The solution of the given linear system of equations is x = 2, y = 1 and z = 2.

Given that the linear system of equations is

2x + 4y + 2z = 16-2x - 3y + z = -52x + 2y - 3z = -3

To solve the system of equations by Cramer's rule method, arrange them in the form of Ax = B as below:

A = [2, 4, 2; -2, -3, 1; 2, 2, -3], x = [x, y, z] and B = [16, -5, -3]

To find the inverse of the coefficient matrix A⁻¹, first, find the determinant of A as below:

|A| = 2[-3 - 2] - 4[-2 + 2] + 2[-8 + 1] = -12

The determinant is non-zero, hence A is invertible

A⁻¹ = 1/|A| [adj A]

where adj A is the transpose of the cofactor matrix [C] of A:

adj A = [C]T

So, we find [C] by replacing each element of A with its cofactor and taking its transpose matrix as below:

C = [5, 2, 6; 2, -2, 2; -4, -4, -4]

Then [C]T = [5, 2, -4; 2, -2, -4; 6, 2, -4]So, A⁻¹ = 1/|A| [adj A] = 1/(-12) [5, 2, -4; 2, -2, -4; 6, 2, -4] = [-5/6, -1/2, 1/2; -1/6, 1/2, 1/2; 1/2, 1/2, 1/2]

To solve the system of equations, we have x = A⁻¹B as below:

x = [-5/6, -1/2, 1/2; -1/6, 1/2, 1/2; 1/2, 1/2, 1/2][16; -5; -3] = [2; 1; 2]

The sine, cosine, cosecant, and secant functions have period 2π; the tangent and cotangent functions have period π.

Definition for Period of a Trigonometric Function :

The pause between any function's repetitions is known as the function's period. The duration of one complete cycle is the period of a trigonometric function. Trigonometric functions include three basic types: sin, cos, and tan, which have periods of -2π, 2π, and π respectively.

If a function repeats itself repeatedly at a predetermined frequency, it is said to be periodic. The formula for t is f(x) = f(x + p), where p is a real number that denotes the period of the function. Period is the interval between two occurrences of the wave.

There are 6 different paths that the ant can take from vertex A and return, visiting every other vertex exactly once.

Let's label the vertices of the cube as A, B, C, D, E, F, G, H, where the ant starts at vertex A. Let's also assume that the ant moves to a neighboring vertex along one of the edges of the cube, and that it cannot revisit a vertex until it has visited all the other vertices.

Since the ant cannot revisit the original vertex until it has visited all the other vertices, it must visit all the other vertices before returning to vertex A. There are 7 other vertices besides A, so the ant must visit these 7 vertices in some order before returning to A.

We can count the number of ways to visit the 7 other vertices in some order as follows. After the ant leaves A, it has 3 choices for its next vertex. Once it reaches this vertex, it has 2 choices for its next vertex, and then only 1 choice for the final vertex before returning to A. This gives a total of:

3 x 2 x 1 = 6

ways to visit the 7 other vertices in some order. Once the ant has visited the 7 other vertices in a particular order, there is only one way for it to return to A, since it must take the remaining edge that connects the current vertex to A.

Therefore, there are 6 different paths that the ant can take from vertex A and return, visiting every other vertex exactly once.

Answer:

smooth, continuous

Step-by-step explanation:

The graph of every polynomial function is both smooth and continuous.

The graph of every polynomial function is both continuous and smooth.

Polynomial functions are defined by a sum of terms, each of which is a constant multiple of the power of the independent variable. The graph of this function is a smooth, continuous curve.

"Continuous" means that there are no sudden jumps or breaks in the graph of the function. This means that the graph can be drawn without lifting the pencil from the paper. In other words, the graph is a connected curve with no gaps or holes.

"Smooth" means that the graph has no sharp corners or abrupt changes in direction. This means that the graph has no cusps, corners, or other singularities.

All polynomial functions have these properties of continuity and smoothness, regardless of their degree or the values of their coefficients. This is because the sum and product of continuous and smooth functions are also continuous and smooth.

Therefore, the graph of every polynomial function is both continuous and smooth.

An effective sampling method is not cast doubt on the usefulness of the sample

The effective sample is a calculation of the approximate sample size needed to obtain the same degree of accuracy as a simple random sample. It is denoted mathematically by the formula n/D, where n represents the sample size and D denotes the design effect. It is employed as a means of condensing the volume of data.

Effective sample size calculations are mostly used for qualitative analyses of the sample size. The sample size calculates the total number of measurements or observations made during an experiment or survey. The effective sample size—rather than the actual sample size—is utilized in this assessment since it is thought that a sample size of 30 is necessary for an analysis to be valid.

Numbers play a crucial role in helping us predict the ebbs and flows in our lives. They are used to measure and quantify patterns and cycles that occur in our daily lives, such as circadian rhythms.

Circadian rhythms are the physical, mental, and behavioral changes that follow a 24-hour cycle, responding primarily to light and darkness in an organism's environment. Numbers help us measure and track these rhythms, allowing us to predict when we will feel awake or sleepy, hungry or full, and so on.

For example, we know that the average human circadian rhythm is 24.2 hours, and that our bodies produce the hormone melatonin at night to help us sleep. By measuring and tracking these numbers, we can predict when we will feel tired and need to sleep, and when we will feel awake and alert.

Numbers also help us predict other patterns in our lives, such as our menstrual cycles, the best times to exercise, and when we are most likely to get sick. By tracking and measuring these numbers, we can better understand and predict the ebbs and flows in our lives and make more informed decisions about our health and well-being.
