I NEED HELP ASAP First, find the increasing functions. Then, classify each increasing function as having a larger or a smaller u

aev [14]

Answer:

In descending order the function are represented as $D>F>A>B>E>C$

Step-by-step explanation:

Whether it is increasing or is the larger or smaller number it all depends on its slope.

Equation of line $y=m(x)+c$ ,and $m$ is the slope.

So we will work with the slopes of each equations and arrange them in descending order.[Greater to larger number sequence]

Slopes are $\frac{4}{3}, \frac{5}{4}, \frac{-2}{1},\frac{7}{4}, \frac{6}{5}, \frac{8}{5}$

We will equate the denominator by taking LCD of it then multiply numerator and denominator with a fix number which can bring all the denominator same.

LCD of the denominator $(1,3,4,5)=60$

Example:

$\frac{4}{3}=\frac{4\times 20}{3\times 20}= \frac{80}{60}$

Similarly we will equate all the fractions.

So the slope are $\frac{80}{60}, \frac{75}{60}, \frac{-120}{60},\frac{105}{60}, \frac{72}{60}, \frac{96}{60}$

In descending order the numbers are:

$\frac{105}{60},\frac{96}{60}, \frac{80}{60}, \frac{75}{60},\frac{72}{60},\frac{-120}{60}$

According to the option the right choice are as follows:

$D>F>A>B>E>C$

Suppose there are 30 people at a party. do you think any two share the same birthday? let's use the random-number table to simul

Arlecino [84]

In this question, you are asked the probability for any of the 30 person to have the same birthday. To answer this it will be easier to calculate how much the probability for no one has same birthday. Let say the first person birthday is 1. Then the next person birthday should be other than 1, which mean 364 possible days out of 365 days. The next person should be 363 possible days out of 365 days
Then the calculation for 30 people would be:

(365!/365-30!)/(365^(30)= (365!/335!)/ 365^30= 29.4%
Then the probability of at least two person have same birthday would be: 100%-29.4%= 70.6%
