Answer:
No
Step-by-step explanation:
It largely depends on required margin of error but I would say that the tested population size is going to be too small.
Answer:
Step-by-step explanation:
This question shouldn't be asked this way. Any change like that should be reflected on both sides. This way makes the question ambiguous.
I'm going to let the graph answer the question for you
The red line is f(x) + 5 = x
The blue line is f(x) = x
You will notice that the red line is 5 units below the blue line. So the answer is B.
You could look at this another way
f(x) = x - 5 when 5 is subtracted from both sides.
Notice the minus sign. It means that the line has been shifted down.
Slope has nothing to do with it. C and D are both incorrect for that reason.
The mean of a set of numbers is the average of the set. To find the mean we must add all the numbers in the set together and divide the sum by how many numbers there are in the set.
95 + 78 + 84 + 86 + 89 + 64 = 496
499 / 6 = 82.67
The mean is 82.67.
The mode of a set of numbers is a number that shows up the most in the set. All the numbers in this set appear once, so, there is no mode.
The median of a set of numbers is the number that is in the very middle of the set. Since the middle has two numbers in it we will find the mean of the two of them.
84 + 86 = 170
170 / 2 = 85
85 is median.
To find the range we need to subtract the smallest number by the largest number.
95 - 64 = 31
31 is the range.
I hope this helps. :)
Answer:
answer is x=4 I'm pretty sure
Step-by-step explanation:
I used a calculator
The area of the pentagon is 1,453 squared centimeters.
Given information-
The length of the apothem of a regular pentagon is 20 cm.
The measure of the perimeter of a regular pentagon is 145.3 cm.
The length of the apothem of a rectangular pentagon is 20 cm.
The measure of the perimeter of a rectangular pentagon is 145.3 cm.
<h3>Pentagon-</h3>
Pentagon is the closed shaped polygon which has 5 sides. When these 5 sides are equal in length then the pentagon is called teh regular pentagon. When four of the sides of pentagon make a rectangle then the pentagon is called the rectangular pentagon.
<h3>Area of regular pentagon-</h3>
Area of regular pentagon is half of the product of its apothem and perimeter. It can be given as,
Thus the area of the pentagon is 1,453 squared centimeters.
