The formula for the sample mean, the margin of error, and the confidence interval.
Sample mean + margin of error = High-end confidence interval
Sample mean - margin of error = Low-end confidence interval
The sample mean is 31.
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
Confidence interval = (27,35).
The margin of error = 4.
The formula for the sample mean, the margin of error, and the confidence interval.
Sample mean + margin of error = High-end confidence interval
Sample mean - margin of error = Low-end confidence interval
Now,
The sample mean = x
x + 4 = 35 ____(1)
x - 4 = 27 _____(2)
From (1) we get,
x = 35 - 4 = 31
From (2) we get,
x = 27 + 4
x = 31
Thus,
The sample mean is 31.

Answer:
The speeds are 88 / 9, 92 / 11, and 96 / 13
Step-by-step explanation:
Since we are already given the equation here, we can plug in the given speeds to find the times. Plugging in 45 will give t = 2 + 350 / 45 which is 2 + 70 / 9. 2 = 18 / 9. We get the time is 88 / 9. Plugging in 55 will give t = 2 + 350 / 55 = 2 + 70 / 11. 2 = 22 / 11. The time is 92 / 11. Plugging in 65 will give t = 2 + 350 / 65 = 2 + 70 / 13. 2 = 26 / 13. The time is 96 / 13.
Answer:
88 -- 9, 92 -- 11, 96 -- 13

A scalene triangle has an angle that measures 47∘ and a second angle that measures 88∘. What is the measure of the third angle?
Answer:
45°
Step-by-step explanation:
The angles of any triangle add up to 180 degrees
add the two known angles: 47+88=135
then subtract the sum from 180 to get answer: 180-135=45
Answer:
45
Step-by-step explanation:
In a triangle the angles add up to 180 degrees. So, we can subtract 47 and 88 from 180. The result, 45, will be your final answer.

What theorem uses a rotation then reflection
Hello!
I see this question relates to mathematics in the topic, geometry.
I have personally learned about rotations and reflections, and would like to knowledge you to the best of my abilities based on the question you have asked.
A rotation and reflection are all translations.
Translations move the figure but don't change its size.
A dilate changes the size of the figure by a scale factor.
All of these mentioned are transformations.
I am not sure if there is a theorem that used rotations and reflections, but i do no that rotations and reflections are both translations.
I hope you found this well,
And have a wonderful day.
Thank you for your support,

Answer:
ok so first you have to multiple 4 and 6 which is 24 times 2 since there is two small rectangles which is 48
then, multiply 10 with 4 which is 40 times 2 since there is two rectangles is 80
then, 6 times 10 which is 60 times 2 since there is two squares which is 120
and lastly, you add 48 with 80 which is 128 plus 120 which is 248
hope this helps have a good day

Math Problem 1: What is the total area of Xavier’s lot?
Use the formula for calculating the area of a trapezoid to help answer your question:
A= a+b2c or front of lot + back of lot/2
Once Bradley has the total area of the lot, he explains to Xavier that the county only allows for 40 percent of any lot to be covered with buildings.
Math Problem 2: What is Xavier’s available lot coverage? (In other words, how big a house can he build?)
Use the formula for calculating percentage to help answer your question:
40/100 = x/Total Area.
Problem 1:
To find the area you must use the formula A = (b_1 + b_2)h/2, so you do (175 + 185)100/2 which is 360*50 = 18000cm².
A = 18000 cm²
Problem 2:
Just use the shown formula, so it would be 40/100 = x/Area, 40*18000/100 = 40*180 = 7200cm²
Available lot coverage = 7200cm²
The area of the trapezoid is 18000 square units.
The area available for lot coverage is 7200 square units.
What is a trapezoid?A trapezoid is a four-sided shape that has one pair of sides parallel.
We have,
Area of a trapezoid:
= 1/2 ( a + b ) h
a and b are the two parallel sides.
h = height of the trapezium.
We have,
a = 175
b = 185
h = 100
Area of a trapezoid:
= 1/2 x ( 175 + 185 ) x 100
= 1/2 x 360 x 100
= 18000
We will calculate 40% lot coverage of the 18000 area.
40% = 40 / 100
So,
= 40/100 x 18000
= 7200
Thus,
The area of the trapezoid is 18000 square units.
The area available for lot coverage is 7200 square units.
