Answer: x < 2

Step-by-step explanation:

Let's solve your inequality step-by-step.

6.2x+1<21−3.8x

Step 1: Simplify both sides of the inequality.

6.2x+1<−3.8x+21

Step 2: Add 3.8x to both sides.

6.2x+1+3.8x<−3.8x+21+3.8x

10x+1<21

Step 3: Subtract 1 from both sides.

10x+1−1<21−1

10x<20

Step 4: Divide both sides by 10.

10x/10 <20x/10

x < 2

satela [25.4K]

Given :-

A dealer sold a photocopy machine at Rs 4200 with 13% VAT to a retailer.
The retailer added transportation cost of Rs 250 , profit Rs 300 and local tax Rs 150 and sold to consumer .
Customer has to pay 13% VAT .

To Find :-

Amount to be paid by the customer .

Solution :-

Here , according to the question ,

$\sf\dashrightarrow Cost\ of \ machine \ = \ Rs 4200$

$\sf\dashrightarrow VAT = 13\%$

Therefore cost after adding VAT ,

$\sf\dashrightarrow Cost = Cost_{initial}+13\% of Cost_{initial}\\$

$\sf\dashrightarrow Cost = Rs4200 + Rs 4200 \times \dfrac{13}{100}\\$

$\sf\dashrightarrow Cost = Rs4200 + Rs546\\$

$\sf\dashrightarrow \bf{ Cost = Rs 4746}$

Again the values added by the retailer before selling to customer ,

Transport = Rs 250
Profit = Rs 300
Tax = Rs 150

Therefore total cost after adding these ,

$\sf\dashrightarrow Cost = Rs( 4746+ 250+ 300 + 150 )\\$

$\sf\dashrightarrow\bf { Cost = Rs 5446}$

Again Selling price after addition of 13% VAT ,

$\sf\dashrightarrow SP = Rs 5446 + 13\% \ of \ Rs 5446\\$

$\sf\dashrightarrow SP = Rs 5446 + \dfrac{13}{100}\times 5446 \\$

$\sf\dashrightarrow SP = Rs (5446 + 707.98) = Rs ( 5446 + 708)\\$

$\sf\dashrightarrow \underline{\underline{\bf SP_{to\ the \ customer} = Rs 6154}}$

Hence the amount to be paid by the customer is Rs 6154 .

(3y^0 x^2)^6 times y^-3 zx8

timurjin [86]

Ok so some basic rules

$(x^m)(x^n)=x^{m+n}$
$(ab)^c=(a^c)(b^c)$
$(x^m)^n=x^{mn}$
$x^0=1$
$x^{-m}= \frac{1}{x^m}$

so
$[(3y^0x^2)^6][y^{-3}zx^8]$
$[(3(1)x^2)^6][y^{-3}zx^8]$
$[(3x^2)^6][y^{-3}zx^8]$
$[(3^6)((x^2)^6)][y^{-3}zx^8]$
$[(3^6)(x^{12})][y^{-3}zx^8]$
$(3^6)(x^{12})(y^{-3})(z)(x^8)$
$(3^6)(x^{12})(x^8)(y^{-3})(z)$
$(3^6)(x^{20})(\frac{1}{y^3})(z)$
$\frac{3^6x^{20}z}{y^3}$
$\frac{729x^{20}z}{y^3}$

Which of the following is not a form of bias? Multiple Choice Portions of the population are excluded or underrepresented from t

Xelga [282]

Answer:

B. Information from the sample is typical of information in the population.

Step-by-step explanation:

In Statistical Research, a Bias refers to the tendency of a sample statistic to systematically overestimate or underestimate a population parameter.

(A)When portions of the population are excluded or underrepresented from the sample, it is a Sampling Bias.

(C)When those responding to a survey or poll differ systematically from the nonrespondents, it is referred to as Non-Response Bias.

(D)When certain groups in the population are systematically underrepresented in the sample, it is referred to as Selection Bias.

Therefore option B is not an example of a Bias.
