Answer:
Q1 = 5, Q3 = 8
Explanation:
There are a total of 19 dots on the chart.
[tex]\begin{gathered} Item\; in\; Q_1=\frac{1}{4}\times19 \\ =4.75th\text{ item} \end{gathered}[/tex]The 5th item on the chart =5, therefore:

What exactly is inequality?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.Make use of the following steps to solve an inequality: Step 1: Remove fractions by multiplying all terms by the fractions' lowest common denominator. Step 2 Combine like terms on both sides of the inequality to simplify. Step 3 Obtain the unknown on one side and the integers on the other by adding or subtracting quantities.So, the inequality that perfectly represents the given situation:

We need to solve the following equation:
[tex]3x+9=-36[/tex]Solving an equation is the same as finding the value of x.
In order to do so, we need to apply a sequence of the same operations on both sides of the equation, until we isolate the variable x on the left side of the equation, and find its value.
First, let's isolate 3x on the left side. We need to subtract 9 from both sides:
[tex]\begin{gathered} 3x+9-9=-36-9 \\ \\ 3x+0=-45 \\ \\ 3x=-45 \end{gathered}[/tex]Now, to end with x on the left side, we need to divide both sides by 3:

Applying the Pythagorean Theorem
AB^2=AC^2+BC^2
substitute given values
AB^2=^2+9^2

AB^2=117
AB=√117Consider the equation -3x+4y=-12 A line parallel to the above line would have a slope of ()/(frac{3}{4}) what would A line perpendicular to the above line have a slope of?
1) Perpendicular lines have reciprocal and opposite slopes. But to properly check it, we need to rewrite the Standard form to the Slope-intercept
So let's rewrite it:
[tex]\begin{gathered} -3x+4y=-12 \\ 4y=-12+3x \\ y=-\frac{12}{4}+\frac{3}{4}x \\ y=\frac{3}{4}x-3 \end{gathered}[/tex]2) Now, we can clearly see the slope. So now, we can tell that a perpendicular line would be reciprocal and opposite to the slope so we can tell that a perpendicular line will be:
[tex]m=-\frac{4}{3}[/tex]Solve:y = 3xx = -2y + 70
Equation1: y = 3x
Equation 2: x = -2y + 70
To solve this system, we will use the value of x of the second equation into the fist equation:
y = 3x = 3(-2y + 70) = -6y + 210
y = -6y + 210
y + 6y = 210
7y = 210
y = 210/7 = 30
y = 30
Now, we will tusethe value of y into the second equation to find the value of x:
x = -2y + 70 = -2(30)+80 = -60 + 70 = 10
x = 10
Answer:
x = 10
y = 30

AnswerBMrs. Thompson hosts an annual art contest for kids, and she keeps a record ofthe number of entries each year.Art contest entriesYear Number of entries201128201227332013201420152735According to the table, what was the rate of change between 2013 and 2014?entries per yearSubmit
We were given a table that describes teh relationship between the year of an art contest entry, and the number of entries for that year. From these datapoints we need to calculate the rate of change between the years of 2013 and 2014.
The rate of change describes how the function is increasing or decreasing for a particular point. For our case, since the two datapoints are only one year apart, we can subtract the number of entries, and that should give us the desired result. This is done below:
[tex]\begin{gathered} \text{rate}=27-33 \\ \text{rate}=-5 \end{gathered}[/tex]The function rate of change between 2013 and 2014 was -5 entries per year.
Distributive Property equation8x4=(_x_)+(_x_)
Answer:
8 x 4 = (8 x 2) + (8 x 2)
Explanation:
The distributive property says that:
a x (b + c) = (a x b) + (a x c)
Then, we can write 4 as (2 + 2), so:
8 x 4 = 8 x ( 2 + 2)
Now, we can apply the distributive property:
8 x 4 = (8 x 2) + (8 x 2)
Therefore, the answer is:
8 x 4 = (8 x 2) + (8 x 2)

Square Root Function and inverse
Answer:
[tex]f^-^1(x)=\frac{x+1}{8}[/tex]
Step-by-step explanation:
f(x) = 8x - 1
==> replace "f(x)" with y
y = 8x - 1
==> inter exchange x and y
x = 8y - 1
==> solve for y now, first step would be to add 1 to both sides
x + 1 = 8y
==> divide both sides by 8
(x+1)/8 = y
==> replace y with f^-1(x)
f^-1(x)=(x+1)/8y

Suppose you have a standard deck of 52 carts. What is the probability that if you select a card at random that it does not have a face value of 9? Round your answer to two decimals
A deck of cards has 13 face values: Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, and King. These face values are present for four different suits (Clubs, Diamonds, Hearts, and Spades) for a total of 52 cards.
An event's probability in an experiment with equally likely outcomes is defined by the following formula, where P (event) means the probability of the event occurring and is founding by dividing the number of outcomes in the event by the number of outcomes in the sample space:
[tex]P(event)=\frac{Number\text{ }of\text{ outcomes in the event}}{Number\text{ of outcomes in the sample space}}[/tex]The probability of not getting the event is given to be:
[tex]P^{\prime}(event)=1-\frac{Number\text{ }of\text{ outcomes in the event}}{Number\text{ of outcomes in the sample space}}[/tex]Since there are 4 cards with a face value of 9, the probability of getting a 9 is:
[tex]P(9)=\frac{4}{52}=\frac{1}{13}[/tex]Therefore, the probability of not getting a 9 is given to be:
