The Market Price of the product is RS. 750.

The Market Price is calculated by dividing the components associated to Discount, which is less than 1, and the Value Added Tax, which more than 1, to the Resulting Price.

c_{M} = \frac{c_{R}}{\left(1-\frac{r_{D}}{100} \right)\cdot \left(1+\frac{r_{T}}{100} \right)} (1)

Where:

c_{M} - Market price, in monetary units.

c_{R} - Resulting price, in monetary units.

r_{D} - Discount rate, in percentage.

r_{T} - Tax rate, in percentage.

If we know that c_{R} = 672, r_{D} = 20 and r_{T} = 12, then the market price is:

c_{M} = \frac{672}{\left(1-\frac{20}{100} \right)\cdot \left(1+\frac{12}{100} \right)}

c_{M} = 750

The market price of the product is RS. 750.

The market price is Rs. 750 which was obtained by creating a mathematical relationship from the given parameters.

PERCENTAGE DISCOUNT = 20%

VAT LEVIED= 12%

PRICE SOLD = 672

Let the MARKET PRICE = m

Hence,

market price * (1 - discount) * (1 + VAT) = price sold

m * (1 - 20%) * (1 + 12%) = 672

m * (1 - 0.2) * (1 + 0.12) = 672

m * 0.8 * 1.12 = 672

0.896m = 672

m = 672 / 0.896

m = Rs. 750

For the function y = -2x2 + 4x + 1, what are the coordinates of the vertex?
umka21 [38]

Answer:

(1,3)

Step-by-step explanation:

The given function is

y =  - 2 {x}^{2}  + 4x + 1

Factor 2 from the first two terms

y =  - 2( {x}^{2}   - 2x) + 1

Add and subtract the square of half the coefficient of x.

y =  - 2( {x}^{2}   - 2x + 1 - 1) + 1

Let us create perfect square trinomial

y =  - 2( {x}^{2}   - 2x + 1 ) +  - 2 \times  - 1 + 1

This implies that:

y =  - 2( {x - 1)}^{2}+  3

Therefore the vertex is (1,3).

We got this by comparing to

y = a( {x - h)}^{2}  + k

What is an equation of a circle whose center is at (2, -4) and is tangent to the line x = -2
n200080 [17]

Answer:

(x-2)^{2} +(y+4)^{2} = \frac{4}{5}

Step-by-step explanation:

Given that the center of the circle is: (2, -4)

tangent to the line x = -2

The equation of a circle has the following formula:

(x-a)^{2} +(y-b)^{2} = r^{2} where a, b is the  center and r is the radius

The distance between the circle and the tangent line is:

d = \frac{2*1 + 2}{\sqrt{2^{2}+4^{2}}   } = 2\frac{\sqrt{5} }{5}

d = r so d^{2} =r^{2} = (2\frac{\sqrt{5} }{5})^{2} = \frac{4}{5}

the equation of the circle is:

(x-2)^{2} +(y+4)^{2} = \frac{4}{5}

An orange juice producer buys oranges from a large orange grove that has one variety of orange. The amount of juice squeezed fro
skad [1K]

Answer:

The probability is 70% that the sample mean amount of juice will be contained between 4.9168 ounces and 5.0832 ounces.

Step-by-step explanation:

To solve this question, the Normal probability distribution and the Central Limit Theorem are important.

Normal probability distribution

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, a large sample size can be approximated to a normal distribution with mean \mu and standard deviation \frac{\sigma}{\sqrt{n}}

In this problem, we have that:

\mu = 5, \sigma = 0.4, n = 25, s = \frac{0.4}{\sqrt{25}} = 0.08

The probability is 70% that the sample mean amount of juice will be contained between what two values symmetrically distributed around the population mean?

The lower end of this interval is the value of X when Z has a pvalue of 0.5 - 0.7/2 = 0.15

The upper end of this interval is the value of X when Z has a pvalue of 0.5 + 0.7/2 = 0.85

Lower end

X when Z has a pvalue of 0.15. So X when Z = -1.04.

Z = \frac{X - \mu}{\sigma}

Due to the Central Limit Theorem

Z = \frac{X - \mu}{s}

-1.04 = \frac{X - 5}{0.08}

X - 5 = -1.04*0.08

X = 4.9168

Upper end

X when Z has a pvalue of 0.15. So X when Z = 1.04.

Z = \frac{X - \mu}{\sigma}

Due to the Central Limit Theorem

Z = \frac{X - \mu}{s}

1.04 = \frac{X - 5}{0.08}

X - 5 = 1.04*0.08

X = 5.0832

The probability is 70% that the sample mean amount of juice will be contained between 4.9168 ounces and 5.0832 ounces.
