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

C 105.66

Step-by-step explanation:

Answer:

105.66

Step-by-step explanation:

The value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10

The equation is given as:

[tex]\frac 1x + \frac{1}{x + 18} = \frac{1}{40}[/tex]

Take the LCM

[tex]\frac{x + 18 + x}{x(x + 18)} = \frac{1}{40}[/tex]

This gives

[tex]\frac{2x + 18}{x(x + 18)} = \frac{1}{40}[/tex]

Cross multiply

[tex]40(2x + 18) =x(x + 18)[/tex]

Expand

[tex]80x + 720 =x^2 + 18x[/tex]

Collect like terms

[tex]x^2 + 18x - 80x -720 = 0[/tex]

[tex]x^2 - 62x -720 = 0[/tex]

Using a graphing calculator, we have:

[tex]x = 72\ or\ x =-10[/tex]

The value of x cannot be negative, because of the context.

So, the value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10

Step-by-step explanation:

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,

Answer:

x = -4

y = 1

(-4,1)

Step-by-step explanation:

x = -11 +7y

5x + 2y = -18

This is a Substitution problem, so you put x = -11+7y into 5x+2y = -18

5(-11 +7y)+2y = -18

5(-11) = -55

5(+7y) = 35y

-55+35y+2y = -18

Now you add 35y and 2y which gives you 37y

-55+37y = -18

Now you add +55 from -55 and -18

37y = 37

You divide each side by 37 so that y = 1

Now you plug y(1) into the equation x = -11+7y

x = -11+7(1)

-11+7 = -4

x = -4

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.

Answer:45.167

Step-by-step explanation:

So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you don't have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167.
