Step-by-step explanation:

Hey, there!!

I hope you mean,

$\frac{ - 1}{2} \: means \: \sqrt{}$

and

$36 = {6}^{2} \: and \: 81 = {9}^{2}$

$so \: \: \sqrt{ \frac{ {6}^{2} }{ {9}^{2} } }$

$or \: ( { \frac{ {6}^{2} }{ {9}^{2} }) }^{ \frac{ - 1}{2} }$

so, the answer is 6/9 or, 2/3.

Hope you are searching this...

The rectangle below has an area of 12y^2+21y^5 The width of the rectangle is equal to the greatest common monomial factor of 12y

Luba_88 [7]

Answer:

Width = $3y^{2}$

Length = $4+7y^{3}$

Step-by-step explanation:

Area of the rectangle = $12y^{2}+21y^{5}$

Width of the rectangle is greatest common monomial factor of $12y^{2}$ and $21y^{5}$ . Monomial means consisting of a one term only. Terms in an algebraic expression are distinguished by symbols of addition and subtraction. So, in expression of Area there are 2 terms. Factorizing the expression of Area will give us the width and length of the rectangle as shown below:

$Area = 12y^{2}+21y^{5}\\\\ Area=3y^{2}(4+7y^{3})$

Since, Area of a rectangle is the product of its length and width, and the monomial factor represents the width, we can write:

Width = $3y^{2}$

Length = $4+7y^{3}$

The sales tax percentage of the store manager report is 7.41%

<h3>How to solve for the sales tax percentage</h3>

Customers are subject to a charge known as sales tax when they buy goods and services.

It is a pass-through tax, which means you must collect it from clients and send the money to your state or local government. the seller do not contribute sales tax.

The sales tax is first calculated by

= price after tax - price before tax

= 513 - 475

= 38

sales tax percentage is calculated using the formula

= (Tax amount / Price before tax) × 100%

= (38 / 513) * 100

= 7.4074

= 7.41%

A man who moves to a new city sees that there are two routes he could take to work. A neighbor who has lived there a long time t

Mandarinka [93]

Answer:

(a) Confidence Interval for Route A is (38.61, 41.39)min

Confidence Interval for Route B is (42.07, 43.93)min

(b) No

Step-by-step explanation:

(a) Route A

Mean=40min, sd=3min, df=33.1, t=2.0675, n=20

CI = (mean + or - t×sd/√n)

CI = (40 + 2.0675×3/√20) = 40+1.39 = 41.39min

CI = (40 - 2.0675×3/√20) = 40 - 1.39 = 38.61min

CI for Route A is (38.61,41.39)min

Route B

Mean=43min, sd=2min, t=2.0675, n=20

CI = (43 + 2.0675×2/√20) = 43+ 0.93 = 43.93min

CI = (43 - 2.0675×2/√20) = 43 - 0.93 = 42.07min

CI for Route B is (42.07,43.93)min

(b) He should not believe the old timer's claim. The man saves an average of 3 minutes a day by driving Route A
