Hello, no worries! It's a pleasure to meet and help you out today.
Median refers to the number that is in the middle of a data set.
The data set you provided has the numbers listed in order, which is great! However, if it's not listed in order, then you must list it in order by yourself.
Data Set: 4, 5, 5, 8, 8, 8, 9, 12, 13
As I said previously, we must find the middle value in the data set.
Data Set: 4, 5, 5, 8, 8, 8, 9, 12, 13
Clearly, the middle value in the data set is 8, so that's the median.
I hope my work has helped you in a way, and I wish you the best of luck with the rest of your assignment! (:

Find the midpoint between coordinates (-8,6)
and (-10,4)
Answer:
(-9, 5)
Step-by-step explanation:
A midpoint is the point, or center at the middle of two given points.
The midpoint formula:
[tex](Xm, Ym)= (\frac{x1 + x2}{2}), (\frac{y1 + y2}{2})[/tex]
X1, Y1 is an endpoint
X2, Y2 is an endpoint.
Explanation:
X1, Y1= (-8, 6)
X2, Y2= (-10, 4)
[tex]Xm, Ym= \frac{(-8)+(-10)}{2}, \frac{(6+(4)}{2}[/tex]
[tex]Xm, Ym= \frac{-18}{2}. \frac{10}{2} \\\\Xm, Ym= (-9, 5)[/tex]
The Midpoint is (-9, 5)

The Equation P= 2.5m + 35 represents the price P (in dollars) of a bracelet, where m is the cost of the materials (in dollars). The price of a bracelet is $115. What is the cost of the materials?
Answer:
The cost of materials is $32.
Step-by-step explanation:
You can solve this in a simple manner:
115 = 2.5m + 35
115-35 = 2.5m
80 = 2.5m
m = 32
You can check your answer by putting 32 back into the equation(P=2.5m+35) and you should get 115(which is price of bracelet)

Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k. (1 point)
k=
Pic Below
Given f(x) and g(x) = f(x) + k, from the graph, we can determine the value of k as 4 units.
In the question,
Given f(x) and g(x) = f(x) + k
From the graph, we can say that there is a shift of 4 units up between f(x) and g(x).
The given lines are parallel lines, so their slopes will be the equal but intercepts will be different for both the lines.
The y-intercept of f(x) = -3 and that of g(x) = 1
Hence, the difference between the intercepts when calculated is (1 -(-3)) = 4.
Therefore, g(x) = f(x) + 4
So, the value of k is 4.

A student believes there is a correlation between the number of texts sent during class and gpa. the student collected data and found that the line of fit can be modeled by the equation ŷ = 3.9 − 0.1x. identify and interpret the slope in this scenario. the slope is 3.9. starting at 0.1, the gpa will increase by 3.9 for every text sent in class. the slope is 3.9. starting at 0.1, the gp will decrease by 3.9 for every text sent in class. the slope is −0.1. starting at 3.9, the gpa will increase by 0.1 for every text sent in class. the slope is −0.1. starting at 3.9, the gpa will decrease by 0.1 for every text sent in class.
The slope is -0.1 starting at 3.9, the GPA will decrease by 0.1 for each text sent in class.
Here we have to find the slope.
The equation given is:
y = 3.9 - 0.1x
As we know that the equation of a line is:
y = mx + c
Therefore we get that the slope is m = -0.1
Starting at 3.9 the GPA will decrease by 0.1 for every text sent in class ( for y = mx + b, a is the slope which is the coefficient of x)
Because the slope is less than 0, it is decreasing.
Therefore the slope is -0.1 and there is a decrease in GPA of 0.1.

Kate's middle school graduation party will be at the skating rink. The cost for each person is $15. The cost of the room for the party's $80 katies parents have set a budget of $478.
Given the function 15z +80=470, determine the maximum number of people who can be at the party.
Answer:
26 people
Step-by-step explanation:
15z +80 = 478
15z = total cost of the people
80 = cost of room
478 = budget
15z + 80 = 478
Subtract 80 from both sides
15z = 398
z = 26.53333

It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression. Since 6 + 6 equals 12, the variable x in the example above is equal to 6. If we are aware of the values of our variables, we can substitute those values for the original variables before evaluating the expression.So, the expressions will be:

Maggie has $960. She spends 1/4 of the money on a mountain bike and 1/6 of
the remainder on bicycle clothing and accessories. She saves the rest of the
money. How much money does she save?
After calculating the given fractions, we have to find that Maggie is left $500 and therefore she saved $500.
What is fraction?Mathematically, a fraction is represented as a numerical value that identifies a portion of a whole. A fraction is a portion or section of any amount that makes up a whole, where a whole can be any number, a certain amount, or an object.
Use this example to help us understand this idea. Pizza is divided into 8 equal pieces in the following illustration. Now, if we want to express one particular piece of the pizza, we can do so by using the notation 1/8, which indicates that we are speaking of one piece out of a total of 8 equally sized pieces.
It means one in eight equally sized portions. It can also be read as follows:
1/8th, or 1 by 8
Given that Maggie has $960
She spends 1/4 of the money on a mountain bike that gives
⇒ 960 - (960 × 1/4)
⇒ 960 - 240
= $720
And the she uses 1/6 of the remainder on bicycle clothing and accessories that gives
⇒ 720 - (720 × 1/6)
⇒ 720 - 120
= $500
Thus, she is left $500 dollar and therefore she saved $500.

P(7 ≤ x ≤ 11) =
The indicated probability of the normal distribution is 0.9332
The natural and social sciences frequently utilize normal distributions to describe real-valued random variables which distributions are unknown, which is why normal distributions are essential in statistics.
The central limit theorem contributes to some of their significance. According to this statement, under some circumstancesThe average of numerous samples (observations) of a random vector with finite mean and variance is itself a random variable, whose distribution conforms to a normal distribution as the number of samples rises. As a result, the distributions of physical quantities, such as error margins, that are predicted to be the sum of numerous distinct processes frequently resemble normal distributions.In the given normal distribution:
mean = 8 and standard deviation = 2
The indicated probability is given by P(7 ≤ x ≤ 11)
The z score of the distribution is given by
Z = ( 11 - 8 ) ÷ 2 = 1.5
From the z-score we can calculate the probability :
P(7 ≤ x ≤ 11) = 0.9332
Therefore the indicated probability is 0.9332

How much does an older girl get?Given,
Oldest gets 5/11 of the share.
The older gets 7/12 of the remainder.
Solution:
Let x be the total amount.
Oldest share = 5/11*x

Answer:

2x-15 = 61°

Step-by-step explanation:
2×-15+3x +5= 180
180+10= 190
190 ÷5x
×=38
Answer:
a) x = 38
b) 61° and 119°
Step-by-step explanation:
Same-side Exterior Angles Theorem
When two parallel lines are intersected by a transversal, the angles that are exterior to the parallel lines and on the same side of the transversal line are supplementary (sum to 180°).
Part (a)Using the Same-side Exterior Angles Theorem, equate the sum of the two angles to 180° and solve for x:
⇒ (2x - 15)° + (3x + 5)° = 180°
⇒ 2x - 15 + 3x + 5 = 180
⇒ 5x - 10 = 180
⇒ 5x = 190
⇒ x = 38
Part (b)Substitute the found value of x from part (a) into the expressions for each angle:
⇒ (2x - 15)°
⇒ (2(38) - 15)°
⇒ (76 - 15)°
⇒ 61°
⇒ (3x + 5)°
⇒ (3(38) + 5)°
⇒ (114 + 5)°
⇒ 119°
Therefore, the two angles are 61° and 119°.

How to solve the simultaneous equationFrom the information given, we have the equations as;
x² + y² = 13 equation (1)y = x + 1 equation (2)Now, substitute the value of y as x + 1 in equation (2) into the equation (1)
We have;
x² + (x + 1)² = 13
expand the bracket
x² + (x + 1)(x+1) = 13
x² + x² + x + x +1 = 13
collect like terms
2x² + 2x + 1 - 13 = 0
2x² + 2x - 12 = 0
Factorize the equation
2x² + 6x - 4x - 12 = 0
Factor the common terms
2x(x + 3) - 4(x + 3) = 0
2x - 4 = 0
x = 2
x = -3
Substitute x as 2 into equation (2)
y = x + 1
y = 2 + 1
