the number of possible ID numbers are 19,656,000 and the probability of getting an ID with initial letters BP is 0.0015.
We have 26 alphabets and 10 digits.
Now, we have ID's that have two letters followed by 5 numbers with no repeating numbers or letters.
So, the possible number of ID's will be calculated by using the permutation.
Possible ID's = 26 × 25 × 10 × 9 × 8 × 7 × 6
Possible ID's = 19,656,000
Number of ID's with the initials BP will be:
Number = 1 × 10 × 9 × 8 × 7 × 6
Number = 30,240
Probability = 30240 / 19,656,000
Probability = 0.0015
Therefore, we get that, the number of possible ID numbers are 19,656,000 and the probability of getting an ID with initial letters BP is 0.0015.

The sum of three lengths of a fence rages from 31 to 40 inches. Two side lengths are 9 and 12 inches. If the length of the third side is x inches, write and solve a compound inequality to show the possible lengths of the third side
Answer:
10 ≤ x ≤ 19
Step-by-step explanation
The sum of the three lengths is 9 + 12 +x = 21 + x
We know the sum ranges from 31 to 40
So we get the inequality
31 ≤ 21 + x ≤ 40
Subtracting 21 from each part of this inequality give
31-21 ≤ x ≤40-21
10 ≤ x ≤ 19
The compound inequality to show the possible lengths of the third side is 10 ≤ x ≤ 19.
What is inequality?A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.
Now it is given as,
Range of sum of three lengths of a fence = 31 to 40 inches
Length of two sides = 9 and 12 inches
Length of third sides = x inches
So, length of sum of three lengths of a fence = 9 + 12 + x
⇒ length of sum of three lengths of a fence = 21 + x
∵ Range of sum of three lengths of a fence = 31 to 40 inches
31 ≤ length of sum of three lengths of a fence ≤ 40
⇒ 31 ≤ 21 + x ≤ 40
Subtracting 21 we get.
10 ≤ x ≤ 19
Thus, the compound inequality to show the possible lengths of the third side is 10 ≤ x ≤ 19.

Cynthia Besch wants to buy a rug for a room that is 19 ft wide and 33 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 275 square feet of carpeting. What dimensions should the rug have?
The dimensions of the rug that Cynthia Besch should buy are 11 ft wide and 25 ft long, which gives an area of 275 ft².
How are the dimensions determined?The dimensions of the rug include the width and the length.
Cynthia is budget-constrained to buy 275 ft² only.
When we factorize 275, we have 1, 5, 11, 25, 55, and 275.
The possible combinations of width and length to get 275 ft² and also ensure that a uniform strip of the floor is left around the rug are 11 ft and 25 ft. This width and length are less than the room's width and length and satisfy the requirement for a uniform strip.
The strip from the room's width and length must be 8 ft each (from all sides).
Data and Calculations:Width of room = 19 ft
Length of room = 33 ft
Area of room = 627 ft²
Dimensions:Width of rug = 11 ft(19 - 8)
Length of rug = 25 ft (33 - 8)
Area = 275 ft² (11 x 25)
Thus, the dimensions of the rug that Cynthia Besch should buy are 11 ft wide and 25 ft long.

the expanded form for 300,648 can be written with only 4 addends . explain how this is possible for a number with 6 digits
Answer:
The expanded form of 300684 can be written with only 4. Add ends, explain how this is possible for a number with 6 digits. When we look at this number, we want to write that in expanded form, which means we want to write the value of each digit. So i look at the value the 4 in the one's place, so its value is 4 actually 4. The 8 is in the tense place, so its value is 810 point. The 6 is in the hundreds place, so its value is 600 point. The 0 is, in the thousands place, that's 0. Thousands. This 0 is in the 10000 point, so we have 010000 and i'm running out of room. So this 3 is in the 100000. Place of its value is 3 times 100000. It just think of it like money, you have 810 dollar bills, 600 dollar bills, etcetera. So if you have 41 dollar bills, you have 4 dollars. If you have 810 dollar bills, you have 80 dollars: 600 dollar bills. You have 600 dollars now. If you have 0 thousands and 010000, you don't have any money in this, so you don't need to write that down. So now i have 300 dollar bills. Some got a value of 300000 point, so they could leave me only 4 digits that i'm adding together reason being this was 0, so there was no value there.

f(1)=30,f(n)=2•f(n-1)-50
The explicit formula of the sequence is Tn = 30 - 20(n - 1)
How to determine the explicit formula of the sequence?The recursive formula of the sequence is given as
f(1) = 30, f(n) = 2 • f(n - 1) - 50
The above means that
f(n) = 2 • f(n - 1) - 50
f(1) = 30
Substitute 2 for n
So, we have
f(2) = 2 • f(2 - 1) - 50
Evaluate the difference
So, we have
f(2) = 2 • f(1) - 50
Substitute f(1) = 30 in f(2) = 2 • f(1) - 50
f(2) = 2 • 30 - 50
Evaluate
f(2) = 10
Substitute 3 for n
So, we have
f(3) = 2 • f(3 - 1) - 50
Evaluate the difference
So, we have
f(3) = 2 • f(2) - 50
Substitute f(2) = 10 in f(3) = 2 • f(2) - 50
f(3) = 2 • 10 - 50
Evaluate
f(3) = -30
So, we have the first three terms to be
30, 10, -10
The above represents an arithmetic sequence, where
First term, a = 30
Common difference = -20
The nth term of the sequence is
Tn = a + (n - 1)d
So, we have
Tn = 30 - 20(n - 1)
Hence, the explicit formula of the sequence is Tn = 30 - 20(n - 1)

The amount invested in CDs is S
The amount invested in bonds is
The amount invested in each type of investment should be $17,000 and $18,000, respectively, as this problem is based on simple interest.
What is a simple mathematical interest?Calculating the amount of interest that will be owed on a sum of money at a certain rate and for a specific period of time is possible using simple interest. Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to compute interest, the principal amount under simple interest remains constant.
based on the facts provided;
Calculating the investment amount:
Since the certificate of deposit is assumed to be x in this instance, the bond should be $35,000 - x.
The formula now should be
($35,000 - x) - x = $1,000
$35,000 - 2x = $1,000
$34,000 = 2x

Zoie is painting a picture that is 15 by 27 inches. She plans to frame it in a frame x inches wide.
Write a polynomial that will be the area of the framed picture.
What will be the area of the picture with the frame if x=3?
If the width of the painting is w, then its length is 2w. Then, since the frame is 2 inches thick on each side of the painting, its width is w+4 and its length is 2w+4. So the area of the rectangle bounded by the frame (which includes both the area of the frame and the area of the painting) is (w+4)(2w+4).
The area of the painting is w×2w=2w2, and the area of the frame is 196 square inches, so the area of the two combined is 2w2+196. However, that is the same area as the other one I described, so we can then equate the two, i.e. (w+4)(2w+4)=2w2+196. You can then solve that equation for w, and hence find all of the relevant dimensions.

I need to prove x*0=0 with field axioms?
Hence proved, x*0 = 0.
A statement that is assumed to be true is referred to as a postulate, axiom, or assumption. It is used as the foundation for further deductive reasoning and arguments.
Given many of the typical formulations of the Peano axioms, for example, this is the base case for the definition of multiplication, so it’s an axiom, not a theorem.
x*o = 0
By using an example as rings:
Therefore, By definition of negotiation
= x + (-x)
0 = x · 1 + ( - x) where 1 is the multiplicative identity,
Now,
= x · ( 0 + 1) + ( - x)
Therefore by distributive law,
= x · 0 + x · 1 + (-x)
Where 1 is the multiplicative identity.
By definition of negotiation,
= x · 0 + x + (-x)
= x · 0 + 0
Where 0 is the additive identity.
= x · 0
