In terms of relative growth​ rate, what is the defining property of exponential​ growth?

Answers

Answer 1

In terms of relative growth rate Exponential growth is characterized by a constant relative growth rate.

Exponential growth is the process of increasing quantity over time. Occurs when the instantaneous rate of change of a quantity over time is proportional to the quantity itself. The exponential growth model has the form

y (t) = C e, where k is the rate constant.

Relative Growth Rate:Relative growth rate (RGR) is the rate of growth relative to size. That is, the rate of growth per unit time relative to the size at that point in time and y'(t)/y(t) is the relative growth rate of a function y at time t.

1/y dy/dt = 1/y d(C eᵏᵗ)/dt

= 1/y(kC eᵏᵗ)

= 1/y ( ky) ( since, y (t) = C eᵏᵗ)

= k

Therefore a constant relative growth rate.

What is exponential function?

A mathematical function with the formula f (x) = a^x is an exponential function. where an is a constant known as the function's base and x is a variable. The transcendental number e, or roughly 2.71828, is the exponential-function base that is most frequently encountered.

Given table is

Length(in.)    4            6       8        10          12

Weight(lb)     1.26      1.49   1.76    2.08       2.45

Assume the exponential function be:

y = ab^x

Putting x = 4 and y = 1.26 in the exponential function:

1.26 = ab⁴  ....(i)

Putting x = 6 and y = 1.49 in the exponential function:

1.49 = ab⁶  ...(ii)

Divide equation (ii) by (i)

1.49/1.26 = ab⁶/ab⁴

149/126 = b⁶/b⁴

149/126 = b⁶⁻⁴

149/126 = b²

b = 1.0874

b  ≈ 1.087

Putting b = 1.087 in equation (i)

1.26 = a(1.087)⁴

a = 1.26/(1.087)⁴

a = 0.9025

a ≈ 0.903

Therefore, y = 0.903 (1.087)^x

A combination is a choice made in mathematics from a group of different elements when the order of the choices is irrelevant (unlike permutations). For instance, if three fruits, such as an apple, an orange, and a pear, are supplied, there are three possible pairings of the two: an apple and a pear. Formally speaking, a k-combination of a set S is a subset of S's k unique components. In other words, two combinations are the same if and only if they have the same members. (It is not important how the individuals in each set are arranged.) The quantity of k-combinations for a set with n components

The available candidates from a group are 8 Democrats and 11 Republicans.

Three Democrats and two Republicans must be included on the committee that we choose.

What is the equation of the straight line which passes through the point 1/2 and cuts off equal intercepts from the axes?

Answers

The equation of the line passing through the point (1, -2) and cutting off equal intercepts from the axes will be x + y +1 = 0.

The equation of the line in the intercept form is expressed as

x/a + y/b = 1

where a is x intercept, b is y intercept and x and y are independent and dependent variables respectively.

Now, according to the question both the intercepts are equal that is

a = b

So, the equation will become

x/a + y/a = 1

x + y = a

Now, since the line passes through (1, -2), so

1 + (-2) = a

=> a = -1

So, the equation of line will be

Line C

Step-by-step explanation:

Given:

"a number y is one-half the difference of a number x and 4”.

Create the equation for the line using the given information:

[tex]\implies y=\dfrac{1}{2}(x-4)[/tex]

Distribute:

[tex]\implies y=\dfrac{1}{2}x-2[/tex]

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

Compare the found equation with the slope-intercept formula:

Slope = ¹/₂y-intercept = -2

The y-intercept is the y-value of the point at which the line crosses the y-axis.  Therefore, the line crosses the y-axis at y = -2.

The slope tells us how much y increases as x increases.  Given the slope is ¹/₂, the line increases by one y-value for every two x-values.

Therefore, the line that represents the given information is line C.

When the process is under control, there will be a high possibility that the value of the sample mean will fall between the two control limits, which is why the lower line, also known as the lower control limit, was chosen.

Mean = 50

Sample size = 16

Standard deviation = 8

We need to find the upper and lower control limits.

So, Lower limit would be

(a) if the new brand has the same lifetime distribution as the previous type of brake pad, what is the sampling distribution of the mean lifetime x? (b) the average life of the pads on these 8 cars turns out to be x 51,800 miles. find the probability that the sample mean lifetime is 51,800 miles or less if the lifetime distribution is unchanged. what conclusion would you draw?

Answers

a) The sampling distribution of the mean lifetime x is: Approximately normal with mean 55,000 and standard error 1591.

b) The probability that the sample mean lifetime is 51,800 miles or less if the lifetime distribution is unchanged is of 0.0222 = 2.22%. As the z-score has an absolute value greater than 2, it shows that this is an unusual measure, hence a conclusion could be drawn that there actually were changes in the distribution.

How to obtain probabilities using the normal distribution?

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex]. Additionally, the distribution is approximately normal with the same mean and the population mean.

The parameters for this problem are given as follows:

[tex]\mu = 55000, \sigma = 4500, n = 8, s = \frac{4500}{\sqrt{8}} = 1591[/tex]

The probability that the sample mean lifetime is 51,800 miles or less is the p-value of Z when X = 51,800, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

Z = (51800 - 5500)/1591

Z = -2.01.

Z = -2.01 has a p-value of 0.0222.

So, our assumption is correct.

Now,95% of the same number is 95% of x

=(95/100) ×300

=95 × 3

=285

Hence,95% of 300 is 285.

a passenger train leaves charleston, wv heading east at the same time a loaded coal train leaves charelston, wv heading west. the passeger train travels23mi/hr faster than the coal train, and in 4 hours the two trains are 412 miles apart. what is the speed of each train

Answers

The speed of the each train = 63

What is Speed?

Speed is defined as : The rate of change of position of an object in any direction.

Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.

Types of Speed

There are four types of speed and they are:

1. Uniform speed

2. Variable speed

3. Average speed

4. Instantaneous speed

Given that

The passenger train travels23mphr faster than the coal train

In 4 hours the two trains are 412 miles apart

Let the speed of  train = x

4*x+4*(x+23)=412

4x + 4x + 92 = 412

8x = 320

x = 40

the speed of the each train = x + 23 = 40 + 23 = 63

Given that

The passenger train travels 23mphr faster than the coal train

suppose a fair die is rolled twice, what is the probability that the sum of the two outcomes is 6, given that the sum is even

Answers

Probability that that sum of the two dice outcomes is 6 is 5/36

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur.

We know,

Probability = Number of events / Total no. of favourable outcomes

If we through two dice then ,

Total number of favourable outcomes = 36

Here, we need the sum of the two outcomes is 6 is

(1, 5) , (2, 4), (3, 3), (4, 2), (5, 1)

So, the number of events = 5

P(of getting sum 6) = 5/ 36

Hence, Probability that that sum of the two dice outcomes is 6 is 5/36

The measures of x are obtained with the Pythagorean Theorem, as follows:

1. x = 10.2.

2. x = 7.2.

3. x = 13.7.

4. x = 36.2.

5. x = 10.7.

What is the Pythagorean Theorem?

The Pythagorean Theorem is a geometry axiom which states that for a right triangle, the length of the hypotenuse squared is equals to the sum  of the lengths of the sides squared.

Hence, for item 1, we have that:

x² + 16² = 19²

x = square root(19² - 16²)

x = 10.2.

For item 2, we have that:

x² + 12² = 14²

x = square root(14² - 12²)

x = 7.2.

For item 3, we have that:

x² + 9.2² = 16.5²

x = square root(16.5² - 9.2²)

x = 13.7.

For item 4, we have that:

The bottom side is bisected into two equal sides of dimension 15.Then x is the hypotenuse of a right triangle of sides 15 and 33, thus:

x² = 15² + 33²

x = square root(15² + 33²)

x = 36.2.

For item 5, first we find the side of the top right triangle, hence:

h² + 16² = 25²

h = square root(25² - 16²)

h = 19.2.

Then the value of x is obtained as follows:

x² + 19.2² = 22²

x = square root(22² - 19.2²)

x = 10.7.
