2/5 of a number is 2/5 greater than 1/3 of a number? What is the number?

Answer:

[tex]y = \frac{3}{4}x -3[/tex] --- Slope intercept

[tex]4y - 3x =- 12[/tex] --- Standard form

Step-by-step explanation:

Given

The attached linear graph

Required

The equation

Select any two points on the line

[tex](x_1,y_1) = (0,-3)[/tex]

[tex](x_2,y_2) = (4,0)[/tex]

Next, calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

So, we have:

[tex]m = \frac{0 --3}{4 - 0}[/tex]

[tex]m = \frac{3}{4}[/tex]

The slope intercept is then calculated using:

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

So, we have:

[tex]y = \frac{3}{4}(x - 0) -3[/tex]

[tex]y = \frac{3}{4}(x) -3[/tex]

[tex]y = \frac{3}{4}x -3[/tex]

Multiply through bu 4

[tex]4y = 3x - 12[/tex]

Subtract 3x from both sides

[tex]4y - 3x =- 12[/tex] --- Standard form

Answer:

Chain referral sampling

Step-by-step explanation:

Chain referral sampling is also known as snowball sampling. In this form of sampling, the samples are collected from the referrals given by the existing samples. The samples are collected and the research is conducted respectively. This method is used in the business marketing also. The places where the people are not known by the company, the method of chain referrals are made and the samples are collected.

Answer:

Solution given:

[tex] sin x=\frac{7}{25}[/tex]

[tex]Cosx=\frac{24}{25}[/tex]

Tanx=[tex]\frac{sinx}{cosx}=\frac{\frac{7}{25}}{\frac{24}{25}}[/tex]

Tan x=[tex] \frac{7*25}{24*25}[/tex]

tan x=[tex] \frac{7}{24}[/tex]

Step-by-step explanation:

Solution :

a). [tex]$\text{Set up hypothesis}$[/tex]

    [tex]$\text{Null hypothesis}$[/tex] : There is no significance between them.

                                  [tex]$H_0:\mu_1=\mu_2$[/tex]

    [tex]$\text{Alternate hypothesis}$[/tex] : There is significance between them.

                                 [tex]$H_1:\mu_1!=\mu_2$[/tex]

b). Test statics

    [tex]$X(\text{mean}) = 2.214$[/tex]

    Standard deviation [tex]$(s.d1)=1.718; \text{Number}(n_1)=20$[/tex]

    [tex]$Y(\text{mean})=2.0115$[/tex]

     Standard deviation [tex]$(s.d2)=1.8917; \text{Number}(n_2)=20$[/tex]

     We use the test statics :

  [tex]$t=\frac{X-Y}{\sqrt{\frac{s.d1^2}{n_1}+\frac{s.d2^2}{n_2}}}$[/tex]

 [tex]$t_0=\frac{2.214-2.0115}{\sqrt{\frac{2.95152}{20}+\frac{3.57853}{20}}}$[/tex]

 [tex]$t_0=0.35$[/tex]

[tex]$|t_0|=0.35$[/tex]

c. The critical value of |t| with minimum [tex]$(n_1-1)$[/tex] , i.e. 19 d.f is [tex]$2.093$[/tex]

   We got [tex]$|t_0|$[/tex] = 0.35439 and |t| = 2.093

Answer:

18 jars can be filled completely.

Step-by-step explanation:

7L=7000ml

1 jar contain 375 ml

375ml can be filled in 1 jar

375ml=1 jar

1 ml = 1/375 jar

7000 ml = 7000× 1/375 jar

7000ml= 18.67 jar

hence 18 jars can be filled completely.

The total number of jars that can be filled with sauce is A = 18 jars

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Saj has made 7 litres of curry sauce = 7000 mL

And , each jar can be completely filled with 375 millilitres of cury sauce

So , the number of jars A = 7000 / 375

On simplifying the equation , we get

A = 18.67 jars

Hence , the number of jars is A = 18 jars

Answer:

100 or 150 units of the product.

Step-by-step explanation:

R = x(1000-4x)

What is the value of x if R = 60,000?

x(1000-4x) = 60000

-4x^2 + 1000x = 60000

x^2 - 250x = -15000

x^2 - 250x + 15000 = 0

Factorize:

(x-100)(x-150) = 0

x-100 = 0 V x-150 = 0

x = 100 V x = 150

The answer is 58.4375

Answer:

$15.75

Step-by-step explanation:

[tex]\frac{y}{15} :\frac{5}{100}[/tex]

y × 100 = 5 × 15

100y = 75

100y ÷ 100 = 75 ÷ 100

y = 0.75

$15 - $0.75

$14.25

[tex]\frac{y}{15} :\frac{10}{100}[/tex]

y × 100 = 10 × 15

100y = 150

100y ÷ 100 = 150 ÷ 100

y = 1.5

$14.25 + $1.50

Answer:

{ -6, -4, -2}

Step-by-step explanation:

Since x > - 8, x can be any number greater than - 8.

x = -7, -6, -5, -4,...

BUT, it can't be equal because it's not using this sign [tex]\geq[/tex]

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

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

1. { -10, -8, -6} can't be an inequality of x because it has -10, -8.

2.{ -8, 0, 8} can't be an inequality of x because of -8.

3.{ -9, 1, 7} can't be an inequality of x because -9 isn't greater than x.

Step-by-step explanation:

m∠A = 70°

m∠B = 30°

m∠C = 80°

Sum of all three angles = 70° + 30° + 80° = 180°

Answer:

(-4,10)

Step-by-step explanation:

The coordinate point of point B (x₁, y₁) will be (−4, 10). Then the correct option is D.

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Point A is located at (2, 6), and point M is located at (−1, 8). If point M is the midpoint of segment AB.

Then the coordinate of the point B(x₁, y₁) will be

We know that the mid-point formula

[tex]\rm (x, y)= \left ( \dfrac{x_1+x_2}{2}, \ \dfrac{y_1+y_2}{2} \right )\\\\(-1, 8)=\left ( \dfrac{2+x_2}{2}, \ \dfrac{6+y_2}{2} \right )\\\\ \dfrac{2+x_2}{2}=-1 \\\\2+x_2=-1\times 2\\\\x_2=-2-2\\\\x_2=4\\\\\dfrac{6+y_2}{2} =8\\\\6+y_2=8\times 2\\\\6+y_2=16\\\\y_2=16-6\\\\y_2=10[/tex]

Then the coordinate point of B (x₁, y₁) is (−4, 10).

Hence, the coordinate point of point B (x₁, y₁) will be (−4, 10). Then the correct option is D.
