Answer:

its 0.3

Step-by-step explanation:

how i found it is by reading the lesson dude

The answer are:

0.334 = 0.3

0.334 = 0.33

0.334 = 0.334  

Given,

0.334

We need to round to the underline place.

The underline is not given here so we will assume:

0.334

0.334

0.334

Example:

245.678

2 - hundreds

4 - tens

5 - ones

6 - tenths

7 - hundredths

8 - thousandths

We have,

0.334

Here the underline is in tenth place.

Rounding to tenth place

we get,

0.3

0.334

Here the underline is in the hundredths place

Rounding to the hundredths place

we get,

0.33

0.334

Here the underline is in the thousandth place

Rounding to the thousandth place

we get,

0.334

Thus,

0.334 = 0.3

0.334 = 0.33

0.334 = 0.334  is our answer.

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.

Answer:

W = 50 + 2.7h

Step-by-step explanation:

A function shows the relationship between two variables (the independent variable and the dependent vaariable). The independent variable is a variable that is independent of any other variable, i.e it is the input of the function while the dependent variable is dependent on other variables hence it is the output of the function.

Given that the weight  of a woman is 50 kg+2.7 kg for each inch over 5 feet. If h is the height over 5 feet ( in inches), the weight (W) can be represented by:

W = 50 + 2.7h

W is in kg

Let x represent the son's age now. 5 years ago, it was x-5, and the father's age was (x -5)+25 = (x+20).

The product of their ages at that time was 900, so we have ...

  (x -5)(x +20) = 900

  x^2 +15x -100 = 900

  x^2 +15x -1000 = 0 . . . . subtract 900

  (x +40)(x -25) = 0 . . . . factor

  x = -40 or +25 . . . . these values make the factors zero

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:

k + h

Step-by-step explanation:

Given that;

The base of a parallelogram is on the x-axis, i.e., it is on the horizontal axis.

The origin (0,0) is located to the left endpoint of the base. This is followed by (k,0) on that same horizontal baseline, now the length of the upper base must be equal to the length of the lower base, from the (k,0) endpoint, the vertical slant line leading to the upper base endpoint is (h,j).

Therefore, the x-coordinate of the fourth vertex will be k unit distant from h.

i.e k+h.

Answer:

Answer:

The chemist will mix 3 liters of the 5% acid solution and 2 liters of the 10% acid solution to get 5 liters of 7% acid solution

Step-by-step explanation:

Here, we are interested in finding the number of liters of each solution the chemist have to make use;

Let the number of liters of the 5% acid solution be x while the number of liters of the 10% acid solution be y

Mathematically;

x + y = 5 •••••••••(i)

Also, let’s work with the percentages now

( x * 5%) + (y * 10%) = (5 * 7%)

0.05x + 0.1y = 0.35 ••••••••(ii)

From i , x = 5-y

Substitute this into ii

0.05(5 -y) + 0.1y = 0.35

0.25 - 0.05y + 0.1y = 0.35

0.25 + 0.05y = 0.35

0.05y = 0.35 -0.25

0.05y = 0.1

y = 0.1/0.05

y = 2

But x + y = 5

x + 2 = 5

x = 5-2

x = 3

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

9m=36

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

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

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.

The correct answer is:(0,6,12,18,24)
