An elevator descends 36 feet in 3 seconds. What
integer represents the elevator's change in
elevation in feet per a second?

Answer: 13.48

Step-By-Step:

Hello there! I will be showing the steps. Let me know if you have any questions or concerns in the comments.

Step 1: For the denominator, recognize that 25 × 4 = 100.

Multiple = 4

Step 2: Multiply both the numerator and denominator by the multiple 4.

[tex]\frac{337 *4 }{25 * 4}[/tex]  

Step 3: Simplify.

[tex]\frac{1348}{100}[/tex]

Step 4: Simplify.

Answer:

$27, $30, $47, $1093, $1851

Step-by-step explanation:

The median is the middle number and the mean is the average. When averaging all the numbers above, you get 611 and the middle number is 47.

The possible data set is $27, $30, $47, $1093, and $1851.

The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.

To create a data set of five freshmen students with the same mean and median as the surveyed college freshmen:

Arrange the five numbers in ascending order to create the data set.

For example, one possible data set is:

$27, $30, $47, $1093, $1851

The mean of this data set is (28+  40 + 47 + 1090 + 1850) / 5 = $611, which is the same as the mean of the surveyed college freshmen.

The median of this data set is 47, which is also the same as the median of the surveyed college freshmen.

Therefore, $27, $30, $47, $1093, and $1851 are the points of the data set.

Answer:

y=2(4^x)

Step-by-step explanation:

if you notice, all the y-values are multiplied by 4 for each x-value. this means 4 is raised to the power of x. however, when you plug this in, you realize that the value produced is only half the actual y-values, so you multiply this whole thing by 2.

y=2(4^x)

Answer:

f(x) = 2^(2x+1)

Step-by-step explanation:

You can tell that each of the outputs of f(x) are powers of 2, so all you have to do is figure out the pattern of the exponents.

2^3 = 8

2^5 = 32

2^7 = 128

2^9 = 512

Step-by-step explanation:

The slack variables make up the difference between the sum of the utilizations and the limit. A separate slack variable is needed for each limit. As with the other variables, its minimum value is zero.

For ( ) ≤ lim constraints, the slack variables are on the left side of the equal sign:

  ( ) +s ≤ lim.

__

For ( ) ≥ lim constraints, the slack variables can be on the right side of the equal sign:

  ( ) = s + lim

The more usual representation in a linear programming matrix is ...

  ( ) - s = lim

__

Here, your constraints are "≤", so each equation will have a unique slack variable added to the left side sum.

Answer:

$619.65

Step-by-step explanation:

We know that he gets paid 180 a week, but we don't know how much he got from the commission of his sales. To find it, you multiply 9770 by 0.045 (because 0.045 = 4.5%) which you get 439.65. You then add the 180 to get 619.65.

9770 * 0.045 = $439.65

$439.65 + $180 = $619.65

Elmer earned $619.65 in that week.

Answer:

The function is:

f(x) = x^3 - 4*x^2 - 3*x + 18.

Below, you can see the graph of the function.

The statements that are true are:

As x increases from negative infinity to positive infinity, the y-values increase, decrease, and then increase again.

You can see this in the graph and may be really hard to see it without the graph, the easier way would be to see the derivate of f(x) and see that is first positive, then negative, and then positive.

f'(x) = 3*x^2 - 8*x - 3

As the leading coefficient is positive, the arms oppen up, and f'(0) = -3

Then is easy to see that from left to right, is positive, then negative, and then positive again.

The domain and range of the function are the set of real numbers.

For the domain, we do not have any denominator nor weird function that has problems in a particular value, so the domain is the set of all real numbers.

And as you can see, as the leading coefficient is an odd power of x, the range will go from minus infinity to infinity (you can also see it in the graph).

The function has a double root.

Yes, in the graph you can see two roots, but this is a 3rd-degree polynomial, so it must have 3 roots, this means that one of the roots in the graph is a double root. (Where the double root is at x = 3, as you can see in the graph)

Answer:

The first row I believe, correct me if I'm wrong.

Answer:

5 cows  and 3 ducks

okay well there are 8 heads and each animal has a head meaning that there are a total of 8 organisms in total. Cows have 4 legs and ducks have 2. Lets say that c is cows and d is ducks. You would have the equations ...

c+d=8

4c+2d=26  

well d techniacally = 8-c, so plug in (8-c) for the value of d

4c+2(8-c)=26.      Distribute to get

4c+16-2c

and then add like terms. Soy ou would get

2c+16=26.

then just isolate the variable but subtracting 16 from both sides and dividing 2 on both sides. The answer you would get is that c=5 so there are 5 cows. Plug in 5 for c so you get 5+d=8 and tadaaaa you subtract 5 from both sides to get that there are 3 ducks.

Answer:

C

Step-by-step explanation:

a straight line is 180, 180-40=140

Answer:

a

A sample survey; we want to gather information about a population based on a sample.

b

An experiment; we want to establish a cause-and-effect relationship

c

An observational study; there is no particular population from which we will sample, we simply observe.

Step-by-step explanation:

Considering the first question

  Are people generally satisfied with how things are going in the country right now?

Here the aim is to gather the opinion of the entire population and since it is impossible to ask each and everyone that make up the population then the best option is to taken a sample of the population and then draw conclusion from their opinion

So the correct option to question a  is  

A sample survey; we want to gather information about a population based on a sample

Considering the second question

Do college students learn basic accounting better in a classroom or using an online course?

Here in other to get the best answer to the question there is need to carry out  a statistical experiment using a group of college student where by a particular group of college student is exposed to learning a particular topic through class room and another group of college student is exposed to learning the same subject through online and then the same test is given to both group of student to determine the outcome of the experiment.

So the solution to the question b is

 An experiment; we want to establish a cause-and-effect relationship

Considering the third  question

How long do your teachers wait on the average after they ask their class a question?  

For the above  question we see that in order to get the correct solution to this problem there is a need to observe the teachers during question and answer section of their teaching so the correct answer to this question is

An observational study; there is no particular population from which we will sample, we simply observe.

Answer:

Well, the correct answer is 119.4347826086956521739130 (after the 130 the whole decimal is repeated.

Step-by-step explanation:

Although if your assignment is asking for an estimate you could probably just say 119 since the first and second decimal is less then 5

The estimation of the expression 8.2 × 6.7 divided by 0.46 is approximately 112.

It is a rough calculation of the value, number, quantity, etc. It doesn't use real calculation but estimation by some method like prediction, using approximation etc.

For this case, we've to esimate the value of the expression:

[tex]E = \dfrac{8.2 \times 6.7}{0.46}[/tex]

Instead of using exact values, let we use:

[tex]8.2 \approx 8\\6.7 \approx 7\\0.46 \approx 0.5 = 1/2[/tex]

Then, we get:

[tex]E = \dfrac{8.2 \times 6.7}{0.46} \approx \dfrac{8 \times 7}{1/2} = 2 \times 8 \times 7= 2 \times 56 = 112[/tex]

Thus, the estimation of the expression 8.2 × 6.7 divided by 0.46 is approximately 112.
