Answer: 1/32
Step-by-step explanation:
There are 35 people in the history club and 3 of them cannot be chosen.
Therefore, there is 32 people Hiroko can be chosen from.
It is at random, so the probobility would be 1/32, as Hiroko is one person.

What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that situations can be represented with an integer that, when combined with the opposite of −5, makes 0.
If you climb up 5 flights of stairs it will give the positive value of 5 when it is added to -5 then it will give zero.
Therefore, If you climb up 5 flights of stairs will give zero. The correct option is D.

What is the magnitude (size) of -5.8?
The magnitude of the negative 5.8 will be 5.8 Then the correct option is D.
What is an absolute function?The absolute function is also known as the mode function. The value of the absolute function is always positive.
The absolute function is given as
f(x) = | x – h | + k
The magnitude of the number will always be positive.
For example - The value of time, length, mass, temperature etc will always positive.
The magnitude of the negative 5.8 will be
⇒ |-5.8|
When the value in the mode may be negative or may be positive, but when the mode is removed, then the value becomes positive.
⇒ |-5.8|
⇒ 5.8
The magnitude of the negative 5.8 will be 5.8
Then the correct option is D.

Michael spent $18 at a local farmers’ market. The apples he bought cost $2 per pound, and the peppers cost $3 per pound. How many pounds of apples and peppers did he buy?
This equation represents the scenario:
2a + 3p = 18
Choose the equations that are equivalent.
Check all that apply.
p = two-thirds a + 6
p = negative two-thirds a + 6
a = negative 1 and one-half p + 9
a = 1 and one-half p + 9
a = StartFraction negative 3 p + 18 Over 2 EndFraction
Answer:
p = -2/3a +6
a = -3/2 p +9
a = -1 1/2 p +9
a = (-3p+18)/2
Step-by-step explanation:
2a + 3p = 18
Solve for a
2a +3p -3p = 18-3p
2a = 18 -3p
Divide by 2
a = 18/2 - 3p/2
a = 9 - 3/2 p
a = -3/2 p +9
a = -1 1/2 p +9
a = (-3p+18)/2
Solve for p
2a +3p = 18
3p = 18 -2a
Divide by 3
p = 18/3 - 2/3 a
p = 6 -2/3a
p = -2/3a +6
Given: ABC
Prove: The medians of ABC are concurrent.
What is step 10 in this proof?
Answer:
As seen , what steps you have written you just want to prove if in a triangle two medians have common point of intersection , a point P, then the third median will also pass through point P.
The point of intersection of medians is called Centroid.
The statement ahead of :Statement: Point P lies on and .
Reason: from above algebra
Point P is the intersection of three medians which is called Centroid of triangle.The Centroid divides the line from opposite vertex in the ratio of 2:1.

A function is shown: f(x) = 16x2 − 1. Choose the equivalent function that best shows the x-intercepts on the graph.
Answer:
Step-by-step explanation:
f(x) = 16x² - 1
The x-intercepts are the roots, i.e., the values of x for which f(x) = 0.
Use the Quadratic Formula to determine the roots.
x = [0±√0²-4·16(-1)]/[2·16] = ±√64/32 = ±8/32 = ±¼
f(x) = 16(x-¼)(x+¼) = (4x-1)(4x+1)
The function which is equivalent to f(x)=16[tex]x^{2}[/tex]-1 is f(x)=(4x+1)(4x-1) and x intercept lies at (1/4,0),(1/4,0).
What is function?Function is relationship between two or more that are variables expressed in equal to form. In a function each value of x must have a corresponding value of y.
How to solve a function?The function which is being give to us is f(x)=16[tex]x^{2}[/tex]-1 and we have to find the equivalent function that best shows the x intercepts on the graph.
f(x)=16[tex]x^{2}[/tex]-1
We can find the factors of the expression 16[tex]x^{2}[/tex]-1.
f(x)=[tex](4x)^{2} -(1)^{2}[/tex]
=(4x+1)(4x-1) [We know that [tex]a^{2} -b^{2}[/tex]=(a+b)(a-b)]
Now we have to find the x intercept. We know that x intercept is a point at which the line touches the x axis means y coordinate will be zero at that point. So we have to put the value of f(x)=0
(4x-1)(4x+1)=0
It can be like under:
4x-1=0,4x+1=0
x=1/4,-1/4
Hence the function which is equivalent to f(x)=16[tex]x^{2}[/tex]-1 is f(x)=(4x+1)(4x-1) and x intercept lies at two points (-1/4,0,(1/4,0).

Answer:
750 pounds each
Step-by-step explanation:
You start with 4000 pounds, and 1000 goes into the big sandbox.
Now you have 3000 pounds left.
These 3000 pounds must be divided into 4 sandboxes, which means
3000/4= Small sandbox capacity=750 pounds
