Answer:

3/14

Step-by-step explanation:

12/56 is equivalent to 3/14

Answer:

14

Step-by-step explanation:

We simplify the fraction 12/56 by dividing the top and bottom by 4 to get 3/14. Thus, it is clear that the question mark is 14.

Answer:

Step-by-step explanation:

(27m^8n^4)^(1/3)

= 27^(1/3) (m6)^(1/3)(n)^(1/3) (m^2n)^(1/3)

= 3m^2n(m^2n)^(1/3)

So the answer is the last.

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:

  33

Step-by-step explanation:

The total number of ratio units is 4+7 = 11. If each one stands for an integer number of students, that number is a multiple of 11 between 24 and 40. The only such number is 3×11 = 33.

There are 33 students in the class.

12 are boys, 21 are girls.

Answer:

B) no solution

Step-by-step explanation:

this can be solved by substitution method

y= ⅔x + 4. (equation 1)

and 2x-3y= 3. (equation 2)

substitute for y into equation 2

2x-3(2/3x + 4) = 3

2x - 2x -12=3

0=15

this is a no solution equation

Here

[tex]\\ \sf\Rrightarrow \dfrac{a_1}{a_2}=\dfrac{2/3}{2}=\dfrac{1}{3}[/tex]

[tex]\\ \sf\Rrightarrow \dfrac{b_1}{b_2}=\dfrac{1}{3}[/tex]

[tex]\\ \sf\Rrightarrow \dfrac{c_1}{c_2}=\dfrac{-4}{3}[/tex]

As

[tex]\\ \sf\Rrightarrow \dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\neq \dfrac{c_1}{c_2}[/tex]

It has no solutions

GE = 26

Step-by-step explanation:

OP = 16 + 9 = 25

PE - OG = 7

Using Pythagorean theorem,

(GE)^2 = (OP)^2 + (PE - OG)^2

=(25)^2 + (7)^2

= 625 + 49

= 674

or

GE = √674 = 25.96 or 26

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:

  55

Step-by-step explanation:

We can use the given relations to write an equation that can be solved for my age 25 years from now.

__

Let x represent my age in 25 years. The age relationships can be summarized as ...

We know 10 years ago my dad was 4 times my age, so we have ...

  4(x -35) = 3x -85

  4x -140 = 3x -85 . . . eliminate parentheses

  x = 55 . . . . . . . . . . . add 140-3x

I will be 55 in 25 years from now.

_____

Additional comment

10 years ago, I was 20 and my dad was 80. Now, I'm 30 and my dad is 90. In 25 years, I'll be 55.

Answer:

prob -3

Step-by-step explanation:

The number 0 is called the additive identity because when you add it to a number, the result you get is the same number. For example, 4 + 0 = 4. Any two numbers whose sum is zero, such as 3 and -3, because 3 + (-3) = 0.

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

$15.75

Step-by-step explanation:

m∠A = 70°

m∠B = 30°

m∠C = 80°

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

Hope it helps....!

Formula to convert radian into degrees

radian × (180°/π) = degrees

7π / 2 × 180 / π = 630°

Answer:

x=2

Step-by-step explanation:

7x - 3 = 11

Add 3 to each side

7x - 3+3 = 11+3

7x = 14

Divide by 7

7x/7 = 14/7

x = 2

[tex]\boxed{\bold{ X=2  }}[/tex] 

now we have to add 3 in both sides

we get that,

now divide 7 in both sides

we get that,

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:
