what is the value of n in the equation? 2.6 x 10^-2 = (5.2 x 10^7) / (2 x 10^n)

Answers

Answer 1

Answer:

  -9

Step-by-step explanation:

  2.6×10^-2 = (5.2×10^7)/(2×10^n) = (5.2/2)×10^(7-n)

  2.6×10^-2 = 2.6×10^(7-n)

The mantissas are equal, so we can equate the exponents:

  -2 = 7 -n

  n = 7 +2 = 9 . . . . . . add n+2

The value of n in the equation is 9.

As the average daily temperature in New York City decreases, the number of persons who are observed wearing sweaters in the workplace increases. This is an example of a __________ correlation. a. causal b. zero c. positive d. negative

Answers

When the average daily temperature in New York City decreases, the number of persons who are observed wearing sweaters in the workplace increases, this implies a negative correlation.

Negative correlation simply means the relationship between two variables where as one variable increases, the other variable will reduce.

Therefore, in a situation where the average daily temperature in New York City decreases and the number of persons who are observed wearing sweaters in the workplace increases, this illustrates a negative correlation.

If you are conducting an experiment where the probability of a success is 0.06 and you are interested in the probability of two successes in 15 trials, the correct probability function to use is the _____.

Answers

In the question, the probability of getting the given number of success

from a specified number of trials is required.

The correct probability function to use is the binomial probability function.

Reasons:

The given parameters are;

The probability of success = 0.06

The number of trials = 15 trials

The probability of interest = The probability of two successes in 15 trials

Solution;

The required probability is given by the following binomial probability

distribution formula;

[tex]P(x) = \dbinom{n}{x}\cdot p^x \cdot q^x = \mathbf{\dfrac{n!}{(n - x)! \cdot x!} \cdot p^x \cdot q^x}[/tex]

Where:

n = Number of trials

x = Number of required success

p = Probability of a success

q = Probability of one failure = 1 - p

For the question, we get;

[tex]P(x) = \dfrac{15!}{(15 - 2)! \times 2!} \times 0.06^2 \times (1 - 0.06)^{15 - 2} \approx \mathbf{0.169}[/tex]

Therefore, the correct option is, a binomial probability function

Aiden runs 1500 meters in 8 minutes. Find the slope of the linear function that represents this relationship.
Aiden runs 187.5 meters perminute.
Aiden runs 180 meters per minute.
Aiden runs 200 meters per minute.
Aiden runs 12 meters per minute.

Answers

Answer: Aiden runs 187.5 meters per minute.
Explanation: Literally divide the two numbers

The slope of the linear function that represents this relationship is Aiden runs 187.5 meters per minute.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Aiden runs 1500 meters in 8 minutes.

We know slope= Rise/ Run

So, slope= 1500 /8

slope= 187.5

Hence, the slope of the linear function that represents this relationship is Aiden runs 187.5 meters per minute.

A check for two hundred fifty dollars as a withdrawal:

Answers

A check for $250 serves as an instruction to the bank to withdraw that amount from the account holder's balance and provide it to the recipient upon deposit or cashing.

When a check is written for two hundred fifty dollars ($250) as a withdrawal, it means that the individual is requesting a withdrawal of $250 from their account using a check.

The check serves as a formal written order instructing the bank to pay the specified amount, which in this case is $250, to the person or entity named on the check. The account holder will typically write the check and provide it to the recipient as a means of transferring funds.

The recipient can then deposit or cash the check at their bank, and the bank will process the transaction by deducting $250 from the account holder's bank balance and providing the recipient with the requested funds.

Given that g(x)=3x - 12, what is the value of x when g(x)=-27?

Answers

Answer:

x = -5

Step-by-step explanation:

If g(x)= 3x - 12, and g(x)= -27 then -27 = 3x -12

Solve for x

     -27 = 3x -12, add 12 to both sides

-27+12 = 3x, add -27+12

     -15 = 3x, divide both sides by 3

      -5 = x

Answer:-93

Step-by-step explanation:

g(x)=3x-12

g(x)=3(-27)-12   -  Substitute

g(x)=-81-12        -  Multipy

We want to find the equation for the graphed rational function. Notice that the options are not given, so I will try to find the function only from the graph.

The function is:

[tex]f(x) = \frac{(x - 5)}{x - 1}[/tex]

How to analyze the graph of a rational function?

The first thing that we can see in the graph is that we have vertical asymptotes at x = 1.

The one in the positive side (of the x range) goes to negative infinity, while the other goes to positive infinity, then the equation will be something like:

[tex]f(x) = \frac{something}{x - 1}[/tex]

Such that the asymptotes are caused when the denominator is equal to zero.

We can see that we also have a horizontal asymptote at y = 1.

This means that, as x tends to infinity, our function will tend to 1, so we have something like:

[tex]f(x) = \frac{(x + b)}{x - 1}[/tex]

The horizontal asymptote is equal to the ratio of the leading coefficients when both polynomials have the same degree, like here, so we can take the two leading coefficients equal to 1, such that:

y = 1/1 = 1

To find the value of b, we evaluate the function in 0:

[tex]f(0) = \frac{b}{-1} = -b[/tex]

And if you look at the graph, you can see that at x = 0 we have:

f(0) = 5

then b = -5

So the function is:

[tex]f(x) = \frac{(x - 5)}{x - 1}[/tex]
