Answer:
-4 !!!
Step-by-step explanation:
Each morning librarians place 560 books on a book shelf in the school library. Each student that visits library that day takes exactly 3 books from this shelf. Let s be the number of students which visit library on a particular day. Let b be the number of books left on the shelf at the end of that day.
b
There are 150 students studying in this school. Use this information to find the domain of the function b(s).
Answer:
The domain of the function b(s) is
[tex]s\in[0,150][/tex]
Step-by-step explanation:
Given that, a total of 560 books is added to the book shelf each morning.
[tex]s[/tex] be the number of the students who visit the library on a particular day and takes exactly 3 books from this shelf.
So, the number of books they take from the shelf is 3s.
The number of remaining books the shelf [tex]=560-3s[/tex].
As , given that [tex]b[/tex] be the number of books left on the shelf at the end of that day, so the required function, [tex]b(s)[/tex], is
[tex]b=560-3s\;\cdots(i)[/tex]
As there are 150 students in the school. So, if no one will go to the library, than [tex]s=0[/tex] which is the minimum value, and if all goes to the library , than [tex]s=150[/tex] which is the maximum value of [tex]s[/tex].
So, the possible value of s is:
[tex]0\leq s\leq150\;\cdots(ii)[/tex]
Now, as there is no book left or there are some books left the negative value of [tex]b[/tex] is not possible. So,
[tex]b\geq0[/tex]
[tex]\Rightarrow 560-3s\geq0[/tex] [fron equation (i)]
[tex]\Rightarrow s\leq 560/3[/tex]
[tex]\Rightarrow s\leq 186\frac{2}{3}[/tex]
as s id the number of students which cant be a fractional value, so the possible nearest value is,
[tex]s\leq 186\;\cdots(iii)[/tex]
From the equations (ii) and (iii), the domain of the function [tex]b(s)[/tex] is
[tex]s\in[0,150][/tex]

follow me and make me as brilliest.....In golf, shooting par is scored as a 0. A score of 2 below par on a hole in golf is called an eagle. Jacob’s friend Michelle scored an eagle on each of her first five holes.
Explain how you would use addition to find the product of –2 and 5 using the integer tiles and the number line.
Answer:
what's the integer tiles you would add 5 groups of negative 2 tiles or removed two groups of five positive tiles on the number line you would Bounce by 5 to the left
Step-by-step explanation:
hope this helps :)
Jacob’s friend Michelle scored -10 by use addition and product of –2 and 5 using the integer tiles and the number line.
What is an integer tile?
Integers tiles are one way of using a material representation to introduce the concept of adding and subtracting.
Now it is given that every time an eagle score, score of 2 below par on a hole i.e -2.
Since jacob scored first 5 holes,
Using the integer tiles :
Drawing 2 tiles each time an eagle is scored:
-2 + - 2 + - 2 + - 2 + - 2 = - 10
Using number line:
Each unit on the number line = - 2
This give ls a unit step 5 times to the left,
-2 + - 2 + - 2 + - 2 + - 2 = - 10
Now using multiplicative property,
–2 and 5 when multiplied also gives -10
or, -5 and 2 when multiplies also gives -10.
Hence, Jacob’s friend Michelle scored -10 by use addition and product of –2 and 5 using the integer tiles and the number line.

14
Answer:
28
Step-by-step explanation:
Answer:
Positive 28
Step-by-step explanation:
When We Multiply (-7) With (2) We get -14. That 14 Is negative An Negative number multiplied by a positive number Equals an negative number.
Rule
Pairs of numbers that are the same sign combine to make a positive product.
(Positive) ⋅ (Positive) = Positive
(Negative) ⋅ (Negative) = Positive
Rule
Pairs of numbers that are opposite signs combine to make a negative product.
(Positive) ⋅ (Negative) = Negative
(Negative) ⋅ (Positive) = Negative
After we have (-14) we still need to multiply it by (-2) Which gives us -28 But WAIT. 2 Negative numbers in a problem will result in a positive number being your answer if its the last part of the problem!

The image of point F after a rotation of 180° counterclockwise around the origin is located at (8,-10)
What is rotation?Rotation means the circular movement over the object around the center.
Rotation can be done in both directions like clockwise as well as counter clockwise
It requires rotation implies negative magnitude
A counter clockwise turns has a positive magnitude.
here, we have,
to determine the image of F:
The coordinate of point F is given as:
F = (-8,10)
The rule of rotation by 180° counterclockwise around the origin is:
(x,y) -> (-x,-y)
So, we have:
F' = (8,-10)
Hence, the image of point F is located at (8,-10)

It is known that 10% of the items produced by a certain machine end up having a flaw. If we select 7 items from the production line, a) What is the probability that at least one of them has a flaw? Part b) What is the probability that exactly three of them has a flaw?
Step-by-step explanation:
p = 0.1, q = 0.9, n = 7
a) Use complementary probability.
P(at least 1) = 1 − P(0)
P(at least 1) = 1 − (0.9)⁷
P(at least 1) = 0.522
b) Use binomial probability.
P = nCr pʳ qⁿ⁻ʳ
P(3) = ₇C₃ (0.1)³ (0.9)⁴
P(3) = 0.023

Answer:
The total weight of the three fishes is 8lb and 13oz
Step-by-step explanation:
2lb 4oz + 1lb 11oz + 4lb + 14 = 7lb 29oz
Remember, there are 16 ounces (oz) in a pound (lb).
So 29oz - 16 oz would be 13oz and the answer would be 8lb and 13 oz.
