Answer:
We can assure the Ann Arbor officials that after look the information we conclude that the mean is 8 h
Step-by-step explanation:
From CI ( 95 % ) = ( 6,7 ; 9,3 )
And the information "large random size sample" we conclude that the population has a normal distribution; a normal distribution has a bell shape curve, and data must spread symmetrically with respect to the mean, therefore the mean is:
6,7 + 9,3 = 16
16/2 = 8
If we need t check we can use the other CI
CI ( 99 % ) = (6,257 , 9,743 )
6,257 + 9,743 = 16
16/2 = 8
We are sure the mean is 8 h

If you buy a burger and fries at your favorite fast food restaurant:___________
A. then GDP will be higher, but consumption spending will be unchanged.
B. then both GDP and consumption spending will be higher.
C. then neither GDP nor consumption will be affected because you would have eaten at home had you not bought the meal at the restaurant.
D. then GDP will be unchanged, but consumption spending will be higher.
Answer:
A. then GDP will be higher, but consumption spending will be unchanged.
Step-by-step explanation:
GDP is the monetary value of all the finished goods and services produced within a country in a specific time period by the country's citizens and foreigners.
It is primarily used to assess the health of a country's economy and it is calculated by adding the following figures together:
personal consumption private investment government spending; and exports
The burger and fries are services provided by the restaurant, which added value to the economy by increasing the GDP.
However, the consumption spending will not be affected because you would have eaten at home had you not bought the meal at the restaurant.
Therefore, the correct option is A " then GDP will be higher, but consumption spending will be unchanged".

the circumference of a circle is 65n. In terms of pi, what is the area of the circle
Answer:
In order to answer this you would need to use this equation: A = πr² (See explanation)
Step-by-step explanation:
So, The circumference of the circle is 65n?
What you need to do is A = πr²
Let's divide 65n by Pi (65/3.14)
That equals 20.70n
Now we have the diameter of the circle. We need the radius for A = πr² .
We need to divide the diameter by two (20.70/2)
We now have the radius of the circle: 10.35n
Now we need to plug 10.35n in our Area equation :A = π10.35²
So now we multiply the Radius by Pi (π * 10.35)
This means that the area of our circle is: A = 32.49
Your answer Is 32.49n

can someone pls help w number 7. we have to find the value of x on a polygon
Answer:
x = 14
Step-by-step explanation:
The sum of the interior angle of a regular polygon is 540 degrees
Since the interior angles are 5, then;
5(9x - 18) = 540
Expand the bracket
5(9x) - 5(18) = 540
45x - 90 = 540
45x = 540 + 90
45x = 630
x = 630/45
x = 14
Hence the value of x is 14
(2x2 − x) + (x2 + 3x − 1)
5x2+2x−1+(4x2−x+2)
(3x2+2x+1)+(x2−1)
−x2−1 +(4x2−x)
some one tell me the sum for all of them please i beg of you all

Solve for the unknown in the following diagram. Round the answer to two decimal places.
degrees
Answer:
x = 63.28°
Step-by-step explanation:
A = 33°
a = 175 mm
C = x
c = 287 mm
Use the Law of Sines to find x
Thus:
[tex] \frac{a}{sin(A)} = \frac{c}{sin(C)} [/tex]
Plug in the values
[tex] \frac{175}{sin(33)} = \frac{287}{sin(x)} [/tex]
Cross multiply
[tex] 175*sin(x) = 287*sin(33) [/tex]
Divide both sides by 175
[tex] sin(x) = \frac{287*sin(33)}{175} [/tex]
[tex] sin(x) = 0.893208017 [/tex]
[tex] x = sin^{-1}(0.893208017) [/tex]
x = 63.28° (2 decimal places)
Many firms use on-the-job training to teach their employees computer programming. Suppose you work in the personnel department of a firm that just finished training a group of its employees to program, and you have been requested to review the performance of one of the trainees on the final test that was given to all trainees. The mean and standard deviation of the test scores are 80 and 5, respectively.
Assuming nothing is known about the distribution, what percentage of test-takers scored better than the trainee who scored 70?
a. Approximentaly 75%
b. Approximentaly all
c. At most 75%
d. At least 75%
e. None of the above
Answer:
d. At least 75%
Step-by-step explanation:
Since nothing is known about the distribution, we use the Chebyshev Theorem.
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]100(1 - \frac{1}{k^{2}})[/tex].
In this problem, we have that:
Mean = 80, standard deviation = 5.
What percentage of test-takers scored better than the trainee who scored 70?
70 = 80 - 2*5
So 70 is two standard deviations below the mean.
Due to the Chebyshev Theorem, we know that at least 75% of the measures are within 2 standard deviations of the mean, between 70 and 90, which means that this percentage is at least 75%, and the correct answer is given by option d.

As a small step to save the environment, Luna came up with an idea for her sweet shop. In exchange for five eclaire boxes, that she gets, she decided to give an eclaire box for free. A group of kids from the locality ate seventy-seven eclaire boxes that week and they collected the boxes to give to Luna and get back eclaires boxes.
How many eclaires boxes do you think they can buy from Luna using the seventy-seven claire boxes?
Answer: Kids will get 15 eclaire boxes in the exchange of 76 boxes.
Step-by-step explanation:
Exchange criteria:
1 Ecalaire box free for 5 eclaire boxes.
Total boxes collected by kids =76
Number of eclaire boxes they will get = 76 ÷5
= [tex]15\dfrac{1}{5}[/tex] or 15 (approx.)
i.e. they will get 15 eclaire boxes in the exchange of 76 boxes.
