Answer: 23 y 24 ( ó -23 y -24)

Step-by-step explanation:

Dos números consecutivos se escriben como:

n y (n + 1)

done n es un numero entero.

Entonces "El producto de dos números consecutivos es 552"

Se escribe como:

n*(n + 1) = 552

n^2 + n = 552

n^2 + n - 552 = 0

Tenemos una cuadrática, las posibles soluciones son obtenidas con la formula de Bhaskara.

[tex]n = \frac{-1 +- \sqrt{1^2 - 4*1*(-552)} }{2} = \frac{-1 +- 47}{2}[/tex]

Las dos soluciones son.

n = (-1 - 47)/2 = -48/2 = -24

n = (-1 + 47)/2 = 46/2 = 23

Si tomamos la primer solución, n = -24

Entonces los dos números consecutivos son:

n = -24

(n + 1) = -23

Si n = 23 entonces

n + 1 = 24

Lo cual tiene sentido, por que lo único que cambia son los signos, los cuales se cancelarían en la multiplicación.

Hey there! I'm happy to help!

We basically want to see what value of y value of the line is at when it crosses x=-3.

If you go to -3 on the x-axis and draw a line straight down, you will see that you hit the line at (-3,-6), so the y value is -6.

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (-7,1)

and slope/m=3

The equation of the line is

[tex]y - 1 = 3(x + 7)[/tex]

Step-by-step explanation:

In order to vertically stretch a function, we just need to multiply the function by our stretch factor.

So, we have the function:

[tex]g(x)=|x|[/tex]

We want to find the equation of this function vertically shrunk by a factor of 1/4. So, multiplied the function by 1/4:

[tex]h(x)=\frac{1}{4}|x|[/tex]

Three flavors of juice are offered at a school cafeteria.

The given table:

Orange Grape   Cherry

51             30              69

Total juices = 51+30+69 =150

Now, the probability that a student who bought juice chosen at random purchased the grape flavor= [tex]\dfrac{\text{Number of grape juices}}{\text{Total juices}}[/tex]

[tex]=\dfrac{30}{150}=0.2[/tex]

Hence, the correct option is A.

Answer:

0.2

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

If the diagonals are perpendicular, then the slope of AC will be the opposite reciprocal of the slope of BD.

The slope of AC is:

m = (3 − 3) / (6 − 0) = 0

The slope of BD is:

m = (0 − 6) / (3 − 3) = undefined

The opposite reciprocal of 0 is undefined, so the diagonals are indeed perpendicular.

Specifically, AC is horizontal and BD is vertical.

A better alternative to direct observation to collect data is through Electronic surveys, which are often/are more costly.

A survey is a technique in customer service used to gather feedback from customers on goods, services, and other business-related subjects. Participants are asked how they feel about a topic, and their response is recorded for subsequent use.

A survey in which the distribution of the survey to potential respondents and the gathering of survey data from actual respondents are both heavily reliant on computers. Surveys that are distributed by email over the Internet or company intranets are known as email-based surveys.

Given:

Data is a raw information which can be collected by many mediums.

Now, the data can be collected by experimentation, electronic surveys,  interviews and self administrative questioners.

As, Surveys are the best option but Among all of them the costly one is Electronic surveys.

Step-by-step explanation:

Replace the variable x with -2 in the expression.

f (-2) = -3 x -2 -2

Simplify (-3 x -2 -2) + 9

Multiply -3 by -2

6 - 2 + 9

Subtract 2 from 6

4 + 9

add 4 and 9

The required simplified value of the function [tex]f(-2) + 9[/tex] as is 13.

Given that,
f(x) = -3x - 2
To determine
[tex]f(-2) + 9[/tex]

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given function f(x) = -3x - 2
Put x = -2 and add the function with 9

Answer: C

Step-by-step explanation:

The difference between an equation and expression is the equals sign. A simple way to tell of an expression is an equation is if there is an equal sign. If there is an equal sign, then it is an equation. If not, it is an expression.

Since this problem is asking for expression, it would be easiest to find an answer choice that doesn't include the word "_____is _____". This is a way to say _____ is equal to ____.

Let's go through each of the answer choices and write the equation/expression for it.

A. Equation

(4+x)/2=12

---------------------------------------------------------------------------------------------------------

B. Equation

p-1=14

---------------------------------------------------------------------------------------------------------

C. Expression

3c-9

D. Equation

There is no indication that the expression is equal to anything, therefore C is the correct answer.

#SPJ2

Answer:

0.31084

Step-by-step explanation:

When given a question where by a random sample is chosen for the population, the z score formula used =

z = (x-μ)/Standard error

where x is the raw score

μ is the population mean

Standard error = σ/√n,

σ is the population standard deviation

n = number of samples

For x = $114,000, μ = $115,000, σ = 25,000, n = 100

z = (x-μ)/Standard error

= z = (x-μ)/ σ/√n

z = 114,000 - 115,000/ 25,000/√100

= -1000/25,000/10

= -1000/2500

z = -0.4

Determining the probability value from Z-Table:

P(x = 114000) = P(z = -0.4)

= 0.34458

For x = $116,000, μ = $115,000, σ = 25,000, n = 100

z = (x-μ)/Standard error

= z = (x-μ)/ σ/√n

z = 116,000 - 115,000/ 25,000/√100

= 1000/25,000/10

= 1000/2500

= 0.4

Determining the Probability value from Z-Table:

P(x = 116000) = P(z = 0.4)

= 0.65542

The probability that the sample mean selling price was between $114,000 and $116,000 is calculated as

= P(114,000< x < 116,000)

= P(-Z<x<Z)

= P(-0.4<x< 0.4

= 0.65542 - 0.34458

= 0.31084

Therefore, the probability that the sample mean selling price was between $114,000 and $116,000 is 0.31084

Answer: 68/7

Step-by-step explanation:

given data:

(3/2) of (4/7) multiplied by [(10x3)-(8x2)]​

first we break it down into smaller sets.

= ( 3/2 ) * (4/7 )

= 6/7 * [(10x3)-(8x2)]​

we open the brackets

=  6/7 * (10x3)-(8x2)

= 6/7 * 30 –16

= 6*30/7 –16

= 180/7 – 16
