Step-by-step explanation:

use the equation given

Answer:Coupon B gives the lower price. The price of coupon B is $4.4 less than the price of coupon A.

Step-by-step explanation:

The coupon B gives the lower price. That means by using coupon B, Ann will get a chair at $33.

The price with coupon B is $2.75 less than the price with coupon A.

A coupon is a ticket or document that can be redeemed for a financial discount or rebate when purchasing a product.

A percentage is a proportion that shows a number as parts per hundred

To convert a percent into a number divide the given percentage by hundred and remove the percentage sign.

According to the given question.

Ann has two coupon for a Chair.

Coupon A is giving 35 percent off on a chair of $55.

And, coupon B is giving $22 0ff on chair 0f $55

If Ann uses coupon A then the amount she have to pay for chair is given by

Amount = [tex]55-\frac{35}{100} ($55)[/tex]

Amount = [tex]55-0.35(55)[/tex]

Amount = [tex]55-19.25[/tex]

Amount = $35.75

If Ann uses coupon B then the amount she have to pay for chair is given by

Amount = $55 - $22

Amount = $33

Hence, the coupon B gives the lower price. That means by using coupon B, she will get a chair at $33.

Since, through coupon A the amount she have to pay is $35.75 and through B she have to pay the amount of $33.

Now, $35.75 - $33 = $2.75

Thus, the price with coupon B is $2.75 less than the price with coupon A.

Answer:

We use students' t distribution therefore degrees of freedom is v= n-2

Step-by-step explanation:

Confidence Interval Estimate of Population Regression Co efficient β.

To construct the confidence interval for β, the population regression co efficient , we use b, the sample estimate of β. The sampling distribution of b is normally distributed with mean β and a standard deviation σ.y.x / √(x-x`)². That is the variable z = b - β/σ.y.x / √(x-x`)² is a standard normal variable. But σ.y.x  is not known so we use S.y.x and also student's t distribution rather than normal distribution.

t= b - β/S.y.x / √(x-x`)² = b - β/Sb    [Sb = S.y.x / √(x-x`)²]

with v= n-2 degrees of freedom.

Consequently

P [ - t α/2<  b - β/Sb  < t α/2] = 1- α

or

P [ b- t α/2 Sb<   β  < b+ t α/2 Sb] = 1- α

Hence a 100( 1-α) percent confidence for β the population regression coefficient for a particular sample size n <30  is given by

b± t α/2 Sb

Using the same statistic a confidence interval for α can be constructed in the same way for  β  replacing  a with b and Sa with Sb.

a± t α/2 Sa

Using the t statistic  we may construct the confidence interval for U.y.x for the given value X0 in the same manner

Y~0 ± t α/2(n-2) SY~

Y~0= a+b X0

The correct graphs which represents a function is shown in ''Option B.''

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

There are four graphs are shown in image.

Now, We can check all the graph by vertical line test.

If the vertical line cut only at one point of the graph, then, it shows the function.

If the vertical line cut more than one point of the graph, then, it cannot shows the function.

Hence, By vertical line test,

The correct graphs which represents a function is shown in Option B.

What is Multiplication?

Along with addition, subtraction, and division, multiplication is one of the four basic arithmetic operations. In mathematics, multiplication is the repeated addition of groups of equal size.

Here given, Brianna makes a model of the Eiffel Tower for a school project.

It is also given that the model is 25 cm wide at the bottom and Brianna used a scale of 1 centimeter for every 5 meters.

By multiplication, we can find the actual length of Eiffel tower

Here 1 centimeter for every 5 meters.

So, 25 centimeter means (5×25) = 125 meters.

Therefore, the actual length of the Eiffel tower is 125 meters.

90 PLEASE MARK ME BRAINLLIEST

Step-by-step explanation:

289.76-54.88-54.88=180/2=90

Perimeter is the sum of the length of the sides used to make the given figure. The length of the field is 90 meters.

Perimeter is the sum of the length of the sides used to make the given figure.

Given that the width of the field is 54.88 meters and the perimeter of the field is 289.76 meters. Therefore, we can write the perimeter as,

Perimeter = 2(Length + Width)

289.76 meters = 2(Length + 54.88 meters)

289.76meters / 2 = Length + 54.88 meters

144.88metes = Length + 54.88 meters

Length = 144.88 meters - 54.88 meters

Length = 90 meters

Hence, the length of the field is 90 meters.
