jeyben [28]

Answer:

Profit percentage $=20\%$ .

Step-by-step explanation:

Given: A garment dealer buys goods for $\text{Rs.}\:10,000$ and spend $\text{Rs.}\:800$ on freight. He seeks the entire stock for $\text{Rs.}\:12,960$ .

To find: His loss/profit percentage.

Solution:

We have,

Cost price of goods $=\text{Rs.}\:10,000$

Spent on freight $=\text{Rs.}\:800$

So, total cost of goods $=\text{Rs.}\:10000+\text{Rs.}\:800=\text{Rs.}\:10,800$

Selling price of entire stock $=\text{Rs.}\: 12,960.$

Now, Profit $=\text{Selling price}-\text{Cost price}$

So, Profit $=\text{Rs.}\:12, 960-\text{Rs.}\:10,800=\text{Rs.}\:2160$

Now,

$\text{Profit\:\%}= \frac{\text{Profit}}{\text{Cost price}} \times 100\%$

$\implies\text{Profit\:\%}= \frac{2160}{\text{10,800}} \times 100\%$

$\implies\text{Profit\:\%}= \frac{2160}{108}\%$

$\implies\text{Profit\:\%}= 20\%$

Hence, profit percentage $=20\%$ .

What two formulas are necessary to find the area of a segment of a circle? i will name brainliest!!!!!!!

NeTakaya

The necessary formulas to get the area of a circle’s segment are the area of the circle’s sector and the triangle it is bounded by.

Hence the formula for the segment’s area is:Area of Segment = Area of sector – area of the triangle.

The formula of the area of a circle’s sector is:Area of Sector = $\frac{central-angle}{2}$ x (radius of circle)²

While the formula for the area of a triangle is:Area of Triangle = $\frac{1}{2}$ x base of triangle x height of triangle

In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6965 subjects randomly sele

vladimir1956 [14]

The hypothesis test shows that we reject the null hypothesis and there is sufficient evidence to support the claim that the return rate is less than 20%

<h3>What is the claim that the return rate is less than 20% by using a statistical hypothesis method?</h3>

The claim that the return rate is less than 20% is p < 0.2. From the given information, we can compute our null hypothesis and alternative hypothesis as:

$\mathbf{H_o :p =0.2}$

$\mathbf{H_i:p < 0.2}$

Given that:
Sample size (n) = 6965

Sample proportion $\mathbf{\hat p = \dfrac{x}{n} = \dfrac{1302}{6965} \sim0.1869}$

The test statistics for this data can be computed as:

$\mathbf{z = \dfrac{\hat p - p}{\sqrt{\dfrac{p(1-p)}{n}}}}$

$\mathbf{z = \dfrac{0.1869 -0.2}{\sqrt{\dfrac{0.2(1-0.2)}{6965}}}}$

$\mathbf{z = \dfrac{-0.0131}{0.0047929}}$

z = -2.73

From the hypothesis testing, since the p < alternative hypothesis, then our test is a left-tailed test(one-tailed.

Hence, the p-value for the test statistics can be computed as:

P-value = P(Z ≤ z)

P-value = P(Z ≤ - 2.73)

By using the Excel function =NORMDIST (-2.73)

P-value = 0.00317

P-value ≅ 0.003

Therefore, we can conclude that since P-value is less than the significance level at ∝ = 0.01, we reject the null hypothesis and there is sufficient evidence to support the claim that the return rate is less than 20%

Given that the function g is defined by the rule g(x)=3-2x,determine the following

Illusion [34]

Answer:

The value of g(a) is:

g(a) = 3 - 2a

Step-by-step explanation:

Given

As the function g(x) is given by

$g(x)=3-2x$

To determine

g(a) = ?

In order to determine g(a),

substitute x = a in the function g(x) = 3 - 2x

g(x) = 3 - 2x

g(a) = 3 - 2(a)

g(a) = 3 - 2a

Therefore, the value of g(a) is:

g(a) = 3 - 2a
