Answer:

Well, this is simple.

I=PRT

(Interest= Principle*Rate*Time)

So, simply divide both sides by PR

T=I/PR

Your answer is C: T = I divided by the quantity P times R

(This should have been represented as: T= I/PR)

~Hope this helps

13 - 4x = 1 - x<br><br>Step by step please​
Virty [35]

Answer:

13 - 4x = 1 - x

Subtract 13 from both sides.

-4x = -12 - x

Add x to both sides.

-3x = -12

Divide both sides by -3.

x=4

Which counterexample shows that the conjecture "All animals that can fly are birds" is false?
QveST [7]
It seems like you forgot to post the answer choices. However, bats are one animal where they can fly but they aren't birds. So this is one counter-example to prove the claim false. Another example would be any flying insects.

If f(3) = 3^x and g(x) = 7^x then the graph of g(x) will be — the graph of f(x) when x&lt;0.
Allushta [10]

Using the given exponential functions, it is found that the graph of g(x) will be less than than the graph of f(x) when x < 0.

<h3>What are the exponential functions?</h3>

The given exponential functions, f(x) and g(x), are respectively given by:

  • f(x) = 3^x
  • g(x) = 7^x

When x < 0, one possible value is x = -1, hence evaluating the functions at these values:

f(-1) = 3^{-1} = \frac{1}{3}

g(-1) = 7^{-1} = \frac{1}{7}

\frac{1}{3} > \frac{1}{7}, hence, the graph of g(x) will be less than than the graph of f(x) when x < 0.

HELP PLEASE ASAP:

The average rate of change, of the function, between the intervals, x = 2 to x = 6 is: 180.

<h3>What is the Average Rate of Change of a Function?</h3>

Average rate of change = \frac{f(b) - f(a)}{b - a}.

Given the function, f(x)= 3^x + 25,

The average rate of change using the intervals of, x = 2 to x = 6 would be solved as shown below:

a = 2

b = 6

f(a) = f(2)= 3^2 + 25 = 34

f(b) = f(6)= 3^6 + 25 = 754

Average rate of change = \frac{754 - 34}{6 - 2} = \frac{720}{4}

Average rate of change = 180

Therefore, the average rate of change, of the function, between the intervals, x = 2 to x = 6 is: 180.

The average performance rating of the employees at Company A is 6.5 on a scale from 1 to 10 (10 being highest). The standard dev
djyliett [7]

Answer:

The best choice would be hiring a random employee from company A

Step-by-step explanation:

<em>Supposing that the performance rating of employees follow approximately a normal distribution on both companies</em>, we are interested in finding what percentage of employees of each company have a performance rating greater than 5.5 (which is the mean of the scale), when we measure them in terms of z-scores.

In order to do that we standardize the scores of both companies with respect to the mean 5.5 of ratings

The z-value corresponding to company A is

z=\frac{\bar x-\mu}{s}

where

\bar x = mean of company A

\mu = 5.5 (average of rating between 1 and 10)

s = standard deviation of company A

z=\frac{\bar x-\mu}{s}=\frac{6.5-5.5}{2.1}=0.7142

We do the same for company C

z=\frac{\bar x-\mu}{s}=\frac{7.4-5.5}{6.8}=0.2794

This means that 27.49% of employees of company C have a performance rating > 5.5, whereas 71.42% of employees of company B have a  performance rating > 5.5.

So, the best choice would be hiring a random employee from company A
