One equivalent ratio is 1:6

To get this ratio, you divide both parts of 2:12 by 2

2/2 = 1

12/2 = 6

So that's why 2:12 is equivalent to 1:6

From here we could multiply both parts by say 3

1*3 = 3

6*3 = 18

Meaning that 1:6 and 2:12 are equivalent to 3:18

==============================================

Two possible answers are 1:6 and 3:18

There are infinitely possible answers

Answer:

It's actually D (2x - 1)(x+1)

Step-by-step explanation:

The required factor of the polynomial 2x³ - 3x² - 3x + 2 is (2x - 1)(x + 1).

Given that,
One factor of the polynomial 2x3 -3x2 – 3x + 2 is (x - 2), which expression represents the other factor, or factors, of the polynomial is to be determined.

factors can be defined by splitting the value into multipliable values.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
x - 2 is one factor of 2x³ - 3x² - 3x + 2 than
( 2x³ - 3x² - 3x + 2 ) / x - 2 = 2x² + x -1 = (2x - 1)(x + 1)

Thus,  the required factor of the polynomial 2x³ - 3x² - 3x + 2 is (2x - 1)(x + 1).

Answer: p(-4)=0

Step-by-step explanation:

100% correct

If x + 4 is factor of polynomial p than p(-4) = 0. Hence, option C. is correct.

(x + 4) is a factor of polynomial p

Factors can be define splitting the value in multipliable values.

If x + 4 is factor of the polynomial p
This can be true only if,
x + 4 = 0
x = -4, satisfy the polynomial equation i.e.
p(-4) = 0

Thus, x + 4 will be the factor of polynomial p only if p(-4) = 0.

Step-by-step explanation:

Answer:

The price of one Balcony seat = $50

The price of one Ground level seat = $90

The price of one VIP seat = $180

Step-by-step explanation:

Let the price of one Balcony seat = $[tex]x[/tex]

Let the price of one Ground level seat = $[tex]y[/tex]

Let the price of one VIP seat = $[tex]z[/tex]

As per the given table:

[tex]135x+280y+29z=37170 ....... (1)\\150x+270y+58z=42240 ....... (2)\\130x+265y+29z=35570 ....... (3)[/tex]

Multiplying (1) with 2 and subtracting (2) from it:

[tex]120x+290y=32100 \\12x+29y=3210..... (4)[/tex]

Subtracting (3) from (1):

[tex]5x+15y=1600\\x+3y=320 ....... (5)[/tex]

Multiply equation (5) with 12 and subtracting (4) from it:

[tex]7y=630\\\Rightarrow y =\bold{90}[/tex]

By equation (5), putting value of [tex]y[/tex]:

[tex]x=\bold{50}[/tex]

By equation (1), putting the values of [tex]x, y:[/tex]

[tex]135\times 50+280\times 90+29z=37170\\\Rightarrow 29z=37170-31950\\\Rightarrow 29z=5220\\\Rightarrow z =\bold{180}[/tex]

Therefore, the answers are:

The price of one Balcony seat = $50

The price of one Ground level seat = $90

The price of one VIP seat = $180

Answer:

a

The  97% confidence interval is  [tex]1528  <  \mu <  1612 [/tex]

b

Option A and  Option D  are correct

Step-by-step explanation:

From the question we are told that

     The sample size is n =  119

     The  sample  mean is [tex]\$ 1570[/tex]

    The  population standard deviation is  [tex]\sigma  =  \$ 211[/tex]

    Generally given that the confidence level is  97% then the level of significance is mathematically represented as

      [tex]\alpha = (100 - 97 )\%[/tex]

=>    [tex]\alpha = 0.03[/tex]

From the normal  distribution table  the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

     [tex]Z_{\frac{\alpha }{2} } =  2.17[/tex]

Generally the margin of error is mathematically represented as

     [tex]E =  Z_{\frac{\alpha }{2} } *  \frac{\sigma}{\sqrt{n} }[/tex]

    [tex]E =  2.17*  \frac{211}{\sqrt{ 119 } }[/tex]

=>   [tex]E =   41.98 [/tex]

Generally the 97% confidence interval is mathematically represented as

     [tex]\= x  - E  <  \mu <  \= x  + E[/tex]

=>    [tex]1570  - 41.98  <  \mu <  1570  + 41.98 [/tex]

=>    [tex]1528  <  \mu <  1612 [/tex]

Generally looking at confidence interval we see that the width is dependent on the size of the margin of error.

Generally the margin error is directly proportional to the  critical value of  [tex]\frac{\alpha }{2}[/tex] which increases when the confidence level increases and vise versa

Also the margin error is inversely proportional to the square root of  sample size

Hence to reduce the width of the confidence interval we need to lower the confidence level  and increase the sample size

11/12

Step-by-step explanation:

Step-by-step explanation:

Find a common denominator (12)

For 1/6, multiply by 2 to get 2/12 and then add the fractions to get 11/12

Answer: 11/12

Answer:

48.668 ≤ μ ≤ 63.332

Step-by-step explanation:

Given the data:

Sample (X) : 71, 45, 54, 75, 50, 49, 63, 55, 48, 50

Number of samples (n) = 10

α = 95% = 0.05

Determine the range within which the true mean of the fluid samples from the day shift will be with a 95% confidence

True mean = μ

Confidence interval :

m ± t(α/2 ; df) * s/√n

m - t(α/2 ; df) * s/√n ≤ μ ≤ m + t(α/2 ; df) * s/√n

m = sample mean ; s = sample standard deviation ; df = degree of freedom =(n - 1) = (10 - 1) = 9

Calculating the sample mean and standard deviation using calculator to save computation time :

71, 45, 54, 75, 50, 49, 63, 55, 48, 50

m = 56 ; s = 10.25

m - t(0.05/2 ; 9) * s/√n ≤ μ ≤ m + t(0.05/2 ; df) * s/√n

From t table : t(0.05/2 ; 9) = t(0.025, 9) = 2.262

56-2.262 * (10.25/√10) ≤ μ ≤ 56+2.262 * (10.25/√10)

48.668 ≤ μ ≤ 63.332

Answer:

Find the exact value using trigonometric identities.

100

Step-by-step explanation:

The exact value of 2 divided by (0.01) 2 is 20000.

We are given that;

2 divided (0.01)2

Now,

To find the exact value of 2 divided by (0.01) 2, we can use the following steps:

Rewrite 0.01 as a fraction: 0.01 = 1/100

Square both the numerator and the denominator: (0.01) 2 = (1/100) 2 = 1/10000

Flip the fraction and multiply by 2: 2 / (0.01) 2 = 2 x 10000/1 = 20000

Therefore, by algebra the answer will be 20000.

Step-by-step explanation:

Answer:

2 1/6 hours

Step-by-step explanation:

2 1/3 + 1 1/2 + x = 6

convert all mixed numbers to improper fractions

7/3 + 3/2 + x = 6/1

change all numbers to have a common denominator

14/6 + 9/6 + x = 36/6

combine like terms

23/6 + x = 36/6

subtract 23/6 from both sides

x = 13/6

convert improper fraction to mixed number

2 1/6

Answer:

Step-by-step explanation:

Length L = 3 + W

Perimeter P = 42 in

Perimeter = 2L + 2W

plugin values:

42 = 2(3 + W) + 2W

42 = 6 + 2W + 2W

42-6 = 4W

W = 36 / 4

W = 9  

solve L by substituting the value of W=9 into the equation:

L = 3 + W

L = 3 + 9

L = 12

therefore, the dimensions of the rectangle:

                Length = 9 in

                Width = 12 in

The dimensions for the rectangle are 12 in and 9 in if the length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches.

It is defined as the two-dimensional geometry in which the angle between the adjacent sides are 90 degree. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

The length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches.

Let l be the length and w  be the width of the rectangle.

Length l = 3 + w

Perimeter P = 42 in

Perimeter = 2l + 2w

42 = 2(3 + w) + 2w

w = 36/4

w = 9 in

solve for l by substituting the value of w = 9 into the equation:

l = 3 + w

l = 3 + 9

l = 12 in

Thus, the dimensions for the rectangle are 12 in and 9 in if the length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches.
