Answer:
The third one is unbiased because its not specific and it's not involving a group of people or a comparison of things. It's also not specific. It's asking about lowering the expensive sales tax in the city and not to certain people, etc..
Hope it's right:)
This is the concept of scale factor. The linear scale factor is given by:
(height of sculpture)/(height of clothespin)
=20/(5/12)
=48
Given that a woman is 5ft 7 in, the sculpture of this woman would be:
height of sculpture=(scale factor)*(height of the woman)
height of the woman=5 ft 7 inches=5 7/12 ft=67/12 ft
hence the height of the sculpture will be:
67/12×48
=268 ft
Answer: 268 ft
As IQ scores for extensive populaces are focused at 100, the mean = 100.
There ought to be around half scores above or underneath the mean score since mean and middle is about a similar when the populace is substantial.
P(x > 100) = P( z> (100 - 100)/sd ) = P(z > 0)= 0.5
The number of the student who has scored over 100 = 0.5 x 78 = 39 Therefore the answer is 39 students.
Answer:
D. 
Step-by-step explanation:
We are asked to find the GCF of 
.
Since we know that GCF of two numbers is the greatest number that is a factor of both of them.
First of all we will GCF of 44 and 121.
Factors of 44 are: 1, 2, 4, 11, 22, 44.
Factors of 121 are: 1, 11, 11, 121.
We can see that greatest common factor of 44 and 121 is 11.
Now let us find GCF of 
.
Factors of 
are: 
Factors of 
are: 
We can see that greatest common factor of is 
.
Now let us find GCF of 
.
Factors of 
are: 
Factors of 
are:
We can see that greatest common factor of is 
.
Upon combining our all GCFs we will get,
Therefore, GCF of is and option D is the correct choice.
So in the problem, the length of the chord there is the circumference of the tree. So in order to get the diameter of the tree, we must use the formula in getting the circumference of a circle that is stated as follows.
C = 2pi *Radius
so first we need the get the radius of the tree which represent by this formula:
Radius = C /2pi = 8/6.2832 = 1.2732 ft
Diameter = 2*radius = 2 * 1.27 32 = 2.5465 feet
In summary, the diameter of the tree is 2.565 feet.
