Using complete sentences, write an indirect proof proving that if x=30, then 3/4x+5≠20 (3/4 being three over four)

WARRIOR [948]

<span>hypothesis :-
if x=30, then 3/4x+5≠20
let Q:- x=30 P:- 3/4x+5≠20
we need to prove if Q then P (Q →P)

proof :-
lets assume 34x+5=20 is true
now x=30
so
3/4(30)+5=27.5 ≠20
which is a contradiction

In 2004, a magazine's circulation was about 1,000,000 readers. In 2014, the magazine had about 2,000,000 readers. Write a linear

Sever21 [200]

Answer:

$m= \frac{r_2 -r_1}{t_2 -t_1}= \frac{2000000-1000000}{14-4}=100000$

And then we can use for example the first point $(t_1, r_1) = (4, 1000000)$ to find the intercept:

$1000000= 100000*4 + b$

$b=600000$

So then the linear model for this case should be:

$r = 100000 t + 600000$

Step-by-step explanation:

For this case we want to find a linear model given by:

$r =mt+b$

Where r = represent the number of readers , t= years after 2000

m = the slope for the model and b the intercept

For this case we can define the following points from the data given:

$(t_1, r_1) = (4, 1000000)$ 4 years after 2000

$(t_2, r_2) = (14, 2000000)$ 14 years after 2000

We can find the slope with the following formula:

$m= \frac{r_2 -r_1}{t_2 -t_1}= \frac{2000000-1000000}{14-4}=100000$

And then we can use for example the first point $(t_1, r_1) = (4, 1000000)$ to find the intercept:

$1000000= 100000*4 + b$

$b=600000$

So then the linear model for this case should be:

$r = 100000 t + 600000$

A salesperson's ratio of successful signups to the number of people called is 0.625. This month, the salesperson had 125 signu

stellarik [79]

Answer:

The salesperson called 200 people this month.

Step-by-step explanation:

Let us denote the total people that the salesperson called by a variable "x".

Then,

The ratio of successful signups(success ratio) is given as=0.625

Then total no. of successful signups is the product of the success rate and the total no. of signups ,

i.e. Total successful signups = $0.625*x$

According to the data given in the question,

The total no. of successful signups this month =125

or , $0.625*x= 125$

or, $x=\frac{125}{0.625}$

∴x= 200

So, the salesperson called 200 people, out of which only 125 signed up.
