20 Miles

The lower bound of this interval is 51.08, and the upper bound is 58.92.

Given:

Mean = 44

Standard deviation = 9

n = 36

The formula for the confidence interval of the sample mean:

Confidence Interval = [tex]X \pm z * (\sigma / \sqrt n)[/tex]

For a 95% confidence level, the z-score is approximately 1.96.

Plugging in the values into the formula, we have:

Confidence Interval = 44 ± 1.96 * (9/ √36)

                                 = 44 ± 1.96 * (9/ 6)

                                 = 44 ± 1.96 * 1.5

                                 = 44 ± 2.94

Therefore, the symmetrical interval that includes 95% of the sample means is (46.94, 41.06).

Answer:

₹245 is the cost

Step-by-step explanation:

Given:

Cost of the fan = ₹1470

1/6th =  1470/1  × 1/6

(do not cross multiply and simplify)

=  ₹245

Answer:

Rs 1260

Step-by-step explanation:

let x be the cost price , then

x + [tex]\frac{1}{6}[/tex] x = 1470 , that is

[tex]\frac{7}{6}[/tex] x = 1470 ( multiply both sides by 6 to clear the fraction )

7x = 8820 ( divide both sides by 7 )

x = 1260

The cost price was Rs 1260

The factor of the provided polynomial after the factorization process are similar to option B, which is

[tex](x+4)(3x+1)(3x-1)[/tex]

The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.

Find these factors by taking out the common factors.

The given polynomial equation in the problem is,

[tex]9x^3 +36x^2 - x - 4[/tex]

The above equation has the unknown variable x and the highest power of this unknown variable is 3.

Take out the highest common factor 9x², which can divide each term of the first two terms of equation (9x³, 36x²). Thus,

[tex]9x^2(x +4) - x - 4[/tex]

Take out the highest common factor -1 from the second two terms as,

[tex]9x^2(x +4) -1( x + 4)[/tex]

Now take out the common group (x+4) as,

[tex](x +4) ( 9x^2 -1)[/tex]

The second group can be rewritten using the difference of square formula as,

[tex](x +4) ( (3x)^2 -1^2)\\(x+4)(3x+1)(3x-1)[/tex]

Thus, the factor of the provided polynomial after the factorization process are similar to option B, which is

[tex](x+4)(3x+1)(3x-1)[/tex]

[tex]\\ \rm\Rrightarrow m=\dfrac{3-5}{4+9}[/tex]

[tex]\\ \rm\Rrightarrow m=\dfrac{-2}{13}[/tex]

Answer:

y=x+5

Step-by-step explanation:

y-y1=m(x-x1) POINT-SLOPE FORM

Plug in your point and slope

y-3=1(x+2)   (The signs flip because of the negative)

y-3=x+2 (SIMPLIFY)

y=x+5  (Move the three. It is now slope int form)

You can check by plugging in -2 for x, and get 3 for y. (it works)

We will see that this circle is centered at the point (-5, -49) and has a radius of 1.

For a circle of radius R centered at the point (a, b), the equation is:

(x - a)^2 + (y - b)^2 = R^2

In this case, we have:

x^2 + y^2 + 10x + 14y + 73 = 0

We can rewrite this as:

(x^2 + 10x) + (y^2 + 14y) + 73 = 0

(x^2 + 2*5*x + 25) + (y^2 + 2*7*y + 49) - 25 - 49 + 73 = 0

(x + 5)^2 + (y + 49)^2 -74 + 73 = 0

(x + 5)^2 + (y + 49)^2 = 1

So we have a circle centered at the point (-5, -49) with a radius equal to 1.

Using subtraction of normal variables, it is found that Riley is not correct, as the mean is of 8 - 8 = 0.

The mean is the subtraction of the means, while the standard deviation is the square root of the sum of the variances.

Researching this problem on the internet, it is found that, for both samples, the mean is of 8, hence:

8 - 8 = 0.

The original price would be $38 before the sale and without the coupon.

Given that Mai offers a $5 off the regular price of one book bag coupon. The store first uses the discount, then deducts 30% off the lowered price.

The percentage is defined as a ratio expressed as a fraction of 100.

Let the original price would be x before the sale and without the coupon.

As per the given condition,

Since Mai pays $23.10 for the bookbag

⇒ (x -5) - 30% (x -5) = 23.10

⇒ (x -5) - 0.30(x -5) = 23.10

Apply the distributive property of multiplication,

⇒ x - 5 - 0.30x + 1.5 = 23.10

Rearrange the likewise terms and apply the arithmetic operation,

⇒ x - 0.30x = 23.10 + 5 - 1.5

⇒ 0.70x = 26.60

⇒ x = 29.60/0.70

⇒ x = 38

Therefore, the original price would be $38 before the sale and without the coupon.

Zalia paid all total for her day at the science museum is $41.43 including all taxes and tips and other expenses.

It is given that

Admission to the museum = $12.50 per person

Number of persons= 2

Sandwich charge = $5.95

Apple charge = $1.25

Drink charge = $1.69

Tax rate = 7.25%

Tip = 15%

The percentage is value per hundred

Total amount without tax and tip(a)= 12.50*2+5.95+1.25+1.69 = $33.89

Tax(b) = 7.25% of $33.89 = 7.25*33.89/1000= $2.457025

Tip(c) = 15% of $33.89 = 15*33.89/100 = $5.0835

Net amount = a+b+c = $41.43

Therefore, Zalia paid all total for her day at the science museum is $41.43
