why is probability limited to numbers between 0 and 1
Answer:
Probability by definition is the extent to which an event is likely to occur, measured by the ratio of the favourable cases to the whole number of cases possible.
Since number of elements in the set of favourable cases is less than or equal to the number of elements in the set of whole number of cases, their ratio would always end up being 1 or less than one.
Probability equals one when favourable number of cases are same as that of the whole number of cases and probability equals zero when there is no favourable case

The Sum Of 2 Numbers are -11 and their difference is 41.
Answer:
15 and - 26
Step-by-step explanation:
let x and y be the 2 numbers , x > y
x + y = - 11 → (1)
x - y = 41 → (2)
Add the 2 equations term by term to eliminate y
2x = 30 ( divide both sides by 2 )
x = 15
Substitute x = 15 into either of the 2 equations and solve for y
Substituting into (1)
15 + y = - 11 ( subtract 15 from both sides )
y = - 26
The 2 numbers are 15 and - 26

The lateral area of a cylinder is 1872 square cm.The height is 6 cm.What is the radius.
Answer:
9.97 i think
Step-by-step explanation:
Answer:
r = 24.41cm
Step-by-step explanation:
If you're only trying to find the radius, use the equation:
[tex]Area = \pi r^2[/tex]
When rearranged to make r the subject:
[tex]r = \sqrt\frac{Area}{\pi }[/tex]
When the variables are added:
[tex]r = \sqrt\frac{1872}{\pi }[/tex]
[tex]r = 24.41[/tex]
HELPPPPPP PLEASE Jerrod's mountain bike has a tire diameter of 26 inches, How far will the
bike travel in 100 rotations of its tires?
Answer:
Step-by-step explanation:
The process here is to find out how far the tire travels in one rotation, then multiply that by 100. That means we need to find the circumference of the tire since the circumference tells us how far around the outside of the tire it is in inches.
C = πd where d is the diameter of the tire.
C = 3.1415(26) so
C = 81.679 inches. Multiply that by 100 to get
8167.9 inches, which in miles is a little over 1.5 miles

What is the equation of a circle with a center located at (4, -1) and a radius of 9?
Answer:
(x-4)^2 + (y+1)^2 = 81
Step-by-step explanation:
you clearly have internet access and could have very quickly searched for the equation of a circle.
(x-h)^2 + (y-k)^2 = r^2
with (h,k) being the center.
=> (x-4)^2 + (y+1)^2 = 81
The water tank in your school holds 20 liters of water. One day it was 34 full. That day, 14 liters of tank capacity was used up. How many liters of water remained in the tank at the end of the day
Answer:
20
Step-by-step explanation:
The water tank in the school hold 20 liters of water
One day it was 34 liters full
14 liters of water was used up
Therefore the quantity of water left can be calculated as follows
= 34-14
= 20
Hence 20 liters of water remains in the tank

Answer: Check out the diagram below
[tex]1.5 \le x \le 5.5[/tex]
The lengths can be between 4 and 12 units
=======================================================
Explanation:
Let's find an expression that represents the area.
The length is 2x+1 and the width is 3. Multiply those two and we get
3(2x+1) = 6x+3
The area is 6x+3 square units.
In other words, A = 6x+3 represents the area.
------------------
We're then told that [tex]12 \le A \le 36[/tex] saying that the area is between 12 and 36 square units (including both endpoints).
We'll replace the A with 6x+3 and solve for x like so:
[tex]12 \le A \le 36\\\\12 \le 6x+3 \le 36\\\\12-3 \le 6x+3-3 \le 36-3 \ \text{ .... see note1}\\\\9 \le 6x \le 33\\\\\frac{9}{6} \le \frac{6x}{6} \le \frac{33}{6} \ \text{ .... see note2}\\\\\frac{3}{2} \le x \le \frac{11}{2}\\\\1.5 \le x \le 5.5\\\\[/tex]
note1: I subtracted 3 from all sides to undo the "plus 3"
note2: I divided all sides by 6 to undo the multiplication
------------------
We just found that [tex]1.5 \le x \le 5.5\\\\[/tex] so it says that x is between 1.5 and 5.5 including both endpoints.
Plug in the smallest possible x value to find the smallest possible length
length = 2x+1
L = 2(1.5)+1
L = 3+1
L = 4
The smallest possible length is 4 units. Multiply this with the height 3 and we get L*W = 4*3 = 12 which is the smallest possible area.
------------------
Now use x = 5.5 to find the largest value of L possible
L = 2x+1
L = 2(5.5)+1
L = 11+1
L = 12
Then note how L*W = 12*3 = 36 is the max area possible, which matches with that your teacher wrote. So this confirms we have the correct value.
If you're not sure which values go where, check out the diagram below.

Juan is a teacher and takes home 68 papers to grade over the weekend. He can grade at a rate of 6 papers per hour. How many papers would Juan have remaining to grade after working for 7 hours?
Answer:
26 papers
Step-by-step explanation:
Well this is pretty straight forward
if he can grade 6 papers an hour
we just multiply 6 by 7 to get how many papers he graded in 7 hours
6*7= 42
now we subtract 42 from 68 to get how many papers are left to be graded
68-42=26
26 papers are left

a small chocolate sundae costs $3. each topping you add costs $0.50. how much would it cost to get a small sundae with P toppings added?
Answer:
3=0.5p
Step-by-step explanation:
The cost to get a small sundae with P toppings added represented as 3 + 0.5p.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Let's consider the toppings added to the chocolate sundae represented by p.
We will use the unitary method,
The cost of topping added to one chocolate = $0.50
The cost of topping added to p chocolate = $0.5p
So, the cost to get a small sundae with P toppings added is;
3 + 0.5p
Therefore, the cost to get a small sundae with P toppings added represented as 3 + 0.5p
