list M and n are the zeros of the polynomial 3x square + 11 x minus 4 then find the value of m divided n plus n dividedm

Vaselesa [24]

Answer:

Step-by-step explanation:

3x²+11x-4

when splitting the middle term

it becomes

3x²+12x-1x-4

=3x(x+4)-1(x+4)

(3x-1)(x+4)

either 3x-1=0 then x=1/3

or x+4=0 then x= -4

m=1/3

n=-4

therefore

value of m divided n plus n dividedm=1.25

Regal theater in Tikahtnu sold 548 tickets to Moana on Sunday. A adult’s ticket was $6.50 while a child’s ticket was $3.50. In t

irga5000 [103]

Regal theater sold 321 adult tickets and 227 children tickets.

Step-by-step explanation:

Given,

Cost of each adult ticket = $6.50

Cost of each child's ticket = $3.50

Total tickets sold = 548

Total worth of sold tickets = $2881

Let,

x represent the number of adult tickets sold

y represent the number of child tickets sold

According to given statement;

x+y=548 Eqn 1

6.50x+3.50y=2881 Eqn 2

Multiplying Eqn 1 by 6.50

$6.50(x+y=548)\\6.50x+6.50y=3562\ \ \ Eqn\ 3$

Subtracting Eqn 2 from Eqn 3

$(6.50x+6.50y)-(6.50x-3.50y)=3562-2881\\6.50x+6.50y-6.50x-3.50y=681\\3y=681$

Dividing both sides by 3

$\frac{3y}{3}=\frac{681}{3}\\y=227$

Putting y=227 in Eqn 1

$x+227=548\\x=548-227\\x=321$

Regal theater sold 321 adult tickets and 227 children tickets.

Inferential statistics involves using population data to make inferences about a sample. Group of answer choices True False

zhuklara [117]

Answer:

False. Is the inverse process.

See explanation below.

Step-by-step explanation:

We need to remember two important concepts:

A parameter, is a quantity or value who describe a population desired, for example the population mean $\mu$ or the population standard deviation $\sigma$

A statistic, is a quantity or value who represent the information of the sample data, for example the sample mean $\bar X$ or the sample deviation $s$

Based on this we can analyze the statement:

"Inferential statistics involves using population data to make inferences about a sample"

False. Is the inverse process.

If we know the population data then we indeed have parameters and we don't need to do any type of inference in order to estimate these parameters with the statistics.

What we do generally is use the information from the sample in order to obtain statistics representative of the population with the aim to estimate the parameters unknown of the population
