Brianna makes a model of the Eiffel Tower for a school project. Her model is 25 centimeters wide at the bottom
If Brianna used a scale of 1 centimeter for every 5 meters, how vide is the actual Efe Towet?
Answers
The actual Eiffel Tower is 125 meters wide .
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.

A field hockey field is rectangular. Its width is 54.88 meters, and its perimeter is 289.76 meters. Find the length of the field.
Answers
Answer:
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.
What is the perimeter?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.

is an example of
1. confounding, as there is no way to tell whether it was the medication that alleviated his

6 x + 11 y = 29
x + 2 y = 5
Answers
Answer:
x = 3
y = 1
Step-by-step explanation:
x= 5-2y
6x + 11y = 29
6( 5 - 2y ) + 11y = 29
30 - 12y + 11 y = 29
-y = -1
y = 1
x + 2y = 5
x = 5 - 2y
x = 5 - 2
x = 3
x = -11 + 7y
5x + 2y = -18
Answers
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

Ann has two coupons for a chair.
Coupon A:
Coupon B:
35% off of a $55 chair
$22 rebate on a $55 chair
Choose the coupon that gives the lower price.
Then fill in the blank with the correct value.
Answers
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.
What is coupon?A coupon is a ticket or document that can be redeemed for a financial discount or rebate when purchasing a product.
What is percentage?A percentage is a proportion that shows a number as parts per hundred
How to convert percentage into a number?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.

) How many degrees of freedom are available for hypothesis tests and confidence intervals for single regression coefficient
Answers
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
