Answer:
Step-by-step explanation:
From the given information;
The possible number of ways to select these people in order B, C, D, E, and F is:
= 5 × 4 × 3 × 2 × 1
= 120
However, using the order B, C, D, E, and F; The probability that the rumor is repeated is:
= 1/120
= 0.0083
b)
If we make F the subject here by selecting it such that F has not been selected in the first and second draw;
Then:
The possible numbers of ways to select F as third = 4 × 3 × 2 × 1
= 24
Now;
the required probability of F is the third person: = 24/120
= 0.2
c)
Suppose F is selected as the last person to hear the rumor;
Then, the selection of F in the last row = 4 × 3 × 2 × 1
Recall that; the total possible number of ways to select the person is B, C, D,E, and F which is = 120
Then, the required probability of F as the last person to hear the rumor is:
= 24/120
= 0.2
d)
Here, the required probability of F since F has not heard the rumor after it has been told tren times is:
= 4¹⁰
Let's no forget that the total number of possible ways to select the persons using the above criteria is = 5¹⁰
Thus, the required probability of F = 4¹⁰/5¹⁰
= 0.1074

Step-by-step explanation:
1st you will use a^2+b^2=c^2
next you plug them in so it would be a^2+16^2=25^2
next you would solve it to a^2+256=625
then you would get 369 and square root it

Is F={56,777,1,2} a subset of G={2,78,64,333,1,7,56,77,900}?
Answer:
No
Step-by-step explanation:
F is not a subset of G because not every element in F lives in G. Even through 56, 1 and 2, all live in G, and are elements of F, 777 is an element of F but is not an element of G.
(If there is a typo, and every element in F is in fact an element in G, then the answer would be yes, F is a subset of G)
We can see that element 777 is not in set G. Hence the set F is not a subset of set G.
A set is a collection of elements not necessarily arranged in a particular pattern.For a set A to be a subset of another set B, all elements of the set must be found in set B.For the given set F={56,777,1,2}, we can see that the element 777 is not in the set G. Hence the set F is not a subset of set G.

Sam can ride his bike 4.2 kilometers in 6 minutes. Amanda can ride her bike 3.2 kilometers in 8 minutes. Jesse can ride his bike 3.0 kilometers in 5 minutes.
Which rider might go farther in 1 minute?
Answer:
jesse or sam i think its sam by a little bit.
Step-by-step explanation:
Answer:
Sam
Step-by-step explanation:
Find all of their speeds to find how far they will go in 1 minute, by dividing the number of kilometers by the number of minutes:
Sam
4.2/6
= 0.7 km/min
Amanda
3.2/8
= 0.4 km/min
Jesse
3/5
= 0.6 km/min
Since 0.7 is the greatest number, that means Sam is the rider that will go the farthest in one minute.

What is 1092 using the polynomial identity (a+b)2=a2+2ab+b2 ?
Drag and drop the correct responses into the boxes.
Let the smaller value a = Response area and the larger value b = Response area. Then a2+2ab+b2 is Response area. This can be simplified to Response area. So, 1092 is equal to Response area.
Answer:
Step-by-step explanation:
The fill ups is
Smallest number, a= 9
Largest number, b= 100
a²+ 2ab+ b² can be written as 9²+ 2. 9. 100 + 100²
What is Polynomial?A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics.
Given:
Here the smallest number can be taken as 9.
and, here we have 109² then the number can be split as 100 + 9.
Thus, the largest number is 100.
Now, a²+ 2ab+ b² can be written as 9²+ 2. 9. 100 + 100² which can be simplified as 11881.

Four different mathematics books, six different physics books, and two different chemistry books are to be arranged on a shelf. How many different arrangements are possible if a) The books in each particular subject must all stand together b) Only the mathematics books must stand together
Answer:
a) 207,360 ways
b)8,709,120 ways
Step-by-step explanation:
Total number of subjects= 3
Number of mathematics books = 4
Number of physics books = 6
Number of chemistry books = 2
Part a:
Number of possible arrangement s= 3! 4! 6! 2!= 6*24*720*2= 207360 ways
In this we have included 3! because the books have to be placed in such a manner that the books in each particular subject must all stand together.
Part b:
Similarly the mathematics books must stand together so they are treated as
The total number of books will be
Physics books + Chemistry books+ Mathematics books= 6+2+1(treated as single) = 9
But there are 4 different mathematics books so these can be arranged in 4 ways.
Total number of ways in which these books can be arranged = 9! 4!= 8709120 ways.
