Answer:
Step-by-step explanation:
Let the number be x
Two thirds of the number is expressed as ;
[tex]\frac{2}{3} * x\\\frac{2x}{3}[/tex]
The number decreased by 18:
[tex]\frac{2x}{3} - 18[/tex]
If the resulting value is equal to 24;
[tex]\frac{2x}{3} - 18 = 24[/tex]
solve the resulting expression for x
[tex]\frac{2x}{3} - 18 = 24\\\frac{2x}{3} = 24+18\\\frac{2x}{3} -= 42\\2x = 3*42\\x = 126/2\\x = 63[/tex]
Hence the unknown number is 63
Is -2/3 a rational, irrational, whole, natural, or integer number?
(ik its a integer. you can also choose more then one)
Answer:
it is an integer! yes ik u know that but most teachers want it to be in the smallest group u can put it in but other than that it is a real number and it is rational! A whole number is a number that is a counting number like 0,1,2,3 a natural number is a whole number without 0 like 1,2,3 a irrational number is a number that is a repeating decimal which this number isn't

Step-by-step explanation:
Mean Height of Men A formal hypothesis test is to be conducted using the claim that the mean height of men is equal to 174.1 cm. What is the null hypothesis, and how is it denoted? What is the alternative hypothesis, and how is it denoted? What are the possible conclusions that can be made about the null hypothesis? Is it possible to conclude that "there is sufficient evidence to support the claim that the mean height of men is equal to 174.1 cm"?
Answer:
Null hypothesis is; H0: μ = 174.1 cm
Alternative hypothesis is; Ha: μ ≠ 174.1 cm
No, it's not possible to conclude that there is enough evidence to support the claim.
Step-by-step explanation:
We are told that the A formal hypothesis test is to be conducted using the claim that the mean height of men is equal to 174.1 cm.
This means that the null hypothesis is;
H0: μ = 174.1 cm
Now, the alternative hypothesis would state the opposite of the null hypothesis. Thus, alternative hypothesis is;
Ha: μ ≠ 174.1 cm
The possible conclusions to make is that we can either reject the null hypothesis or fail to reject the null hypothesis.
Since we don't have value of test statistic and degree of significance, we cannot conclude that "there is sufficient evidence to support the claim that the mean height of men is equal to 174.1 cm"

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

Henry has $ 21.50 to ride the trolley around San Francisco this week .It will cost him $ 0.50 every time he rides .Identify the dependent variable and independent variable.
Answer:
Dependent: Cost of the ride.
Independent: Number of rides.
Step-by-step explanation:
The independent variable is the variable what we change and the dependent variable is the variables which changes because of that changes.
Here the total cost of the ride changes for any change in the number of rides.
So the number of rides is the independent variable, and the total cost of the ride is the dependent variable

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:

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.

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)

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]
