Answer:

We have the proportion: 8/10 = 100/y

We can solve for y by cross-multiplying.

That is, 8y = 100 * 10 Simplifying the right-hand side, 8y = 1000

Dividing both sides by 8 to solve for y, y = 125

Hence, the value of y is 125.

Finally, we have the expression: y = √80We can simplify this expression by factoring 80 into its prime factors:80 = 2 * 2 * 2 * 2 * 5

Taking the square root of 2 * 2 * 2 * 2, we have:√(2 * 2 * 2 * 2) = 2 * 2 = 4

Therefore, y = 4√5The value of y is 4√5.

A graph of paired (x, y) quantitative data is called a scatterplot. It offers a visual representation of the data plotted as points, assisting in highlighting any patterns in the data. Option B is correct.

Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both coordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.

A scatterplot is a graph of paired​ (x, y) quantitative data. It provides a visual image of the data plotted as​ points, which helps show any patterns in the data.

Thus, the graph of paired (x, y) quantitative data is called a scatterplot. It offers a visual representation of the data plotted as points, assisting in highlighting any patterns in the data. Option B is correct.

The z-score for an individual midge that spends 12. 7 days in its larval stage is -0.636

Given,

The mean number of days that the midge Chaoborus spends in its larval stage = 14.1 days

Standard deviation = 2.2 days

We have to find the z-score for an individual midge that spends 12. 7 days in its larval stage;

Now,

z score = (x - μ) / σ

Here,

x = 12.7

Mean, μ = 14.1

Standard deviation, σ = 2.2

Step-by-step explanation:

In a parallelogram, opposite sides are equal and parallel. Therefore,

QT = PS = 3y ...(1)

PT + TR = PS

y + 2x + 1 = 3x + 9

2x - y = 4 .....(2)

PR = QT = 3y

PR = SQ = 3x + 9 ....(3)

From equations (1) and (3), we can see that:

3y = 3x + 9

y = x + 3

Substitute this value of y in equation (2):

2x - (x + 3) = 4

x = 7

To find the value of y, we can substitute x = 7 in equation (2):

2(7) - y = 4

y = 10

Therefore, x = 7 and y = 10.

The volume of the space outside the pyramid but inside the prism is 250 cubic centimeters.

To find the volume of the space outside the pyramid but inside the prism, we need to subtract the volume of the pyramid from the volume of the prism.

The volume of a rectangular prism is given by the formula: Volume = base area × height.

The base area of the prism is a square with sides measuring 5 centimeters, so the base area is 5 cm × 5 cm = 25 square centimeters.

The height of the prism is given as 12 centimeters.

Therefore, the volume of the prism is 25 square centimeters × 12 centimeters = 300 cubic centimeters.

The volume of a pyramid is given by the formula: Volume = (1/3) × base area × height.

The base area of the pyramid is the same as the base area of the prism, which is 25 square centimeters.

The height of the pyramid is half the height of the prism, which is 12 centimeters ÷ 2 = 6 centimeters.

Therefore, the volume of the pyramid is (1/3) × 25 square centimeters × 6 centimeters = 50 cubic centimeters.

To find the volume of the space outside the pyramid but inside the prism, we subtract the volume of the pyramid from the volume of the prism:

Volume of space = Volume of prism - Volume of a pyramid

= 300 - 50

= 250

Therefore, the volume of the space outside the pyramid but inside the prism is 250 cubic centimeters.

The domain of H is given by the set notation:

Domain: {3, 9, 0}

The domain of a relation represents all the possible input values or x-values in the relation. In the given relation H = {(3, q), (9, n), (0, 3), (9, p)}, we can determine the domain by extracting all the x-values from the ordered pairs.

Looking at the relation, we see that the x-values are 3, 9, and 0. These are the values assigned to the first element of each ordered pair. Thus, the domain of H can be expressed in set notation as {3, 9, 0}.

In set notation, the domain lists all the unique x-values or inputs that exist in the relation. Since each x-value appears only once in the given relation, there are no repetitions or duplicates in the domain set.

Therefore, the domain of H is {3, 9, 0}, indicating that these are the valid input values for the relation H.

It's important to note that the domain of a relation can vary depending on the specific context and constraints. In this case, the domain is determined solely by the values present in the relation H.

14 people can go to the amusement park. Inequality of wealth in major cities Economic inequality comes in many forms, most notably wealth inequality measured by the distribution of wealth and income inequality measured by the distribution of income.

Inequality: 33p + $12.50 ≤ $465

14 people can go to the amusement park

Inequality:

$465= Amount of money they have

$12.50= Parking Cost

$33= Cost of tickets per person

Because they only have $465, they can't spend more than that amount.

Therefore, the inequality would be the ticket cost per person, times the amount of people being payed for (aka x) plus the parking cost is less than or equal to the amount of money they have to spend. Hence the inequality:

33p+ $12.50 ≤ $465

$465- $12.50 = $452.5 (452.5 is how much is left for tickets after subtracting the parking cost)

$33 x1 4 = $462 (14 tickets can be bought for the price of $33)

$462 - $452.5 = $9.5 (9.5 isn't enough for another person)

So, the solution to the inequality is 14 people can go to the amusement park.

To prove that the limit of 1/x as x approaches 5 is 1/5, we manipulate the expression |1/x - 1/5| < epsilon. By introducing the absolute value of x - 5 and setting |x - 5| < 5 * epsilon, we can choose delta = 5 * epsilon. Therefore, for any epsilon > 0, we have |f(x) - L| < epsilon whenever |x - 5| < delta, confirming that lim(x->5) 1/x = 1/5.

Starting with the function f(x) = 1/x, we want to find a value of delta such that |f(x) - L| < epsilon, where L = 1/5 and epsilon > 0.

To do this, we begin by manipulating the expression |f(x) - L| < epsilon:

|1/x - 1/5| < epsilon

Next, we introduce the absolute value of x - 5:

|1/x - 1/5| = |1/x - 1/5| * |x - 5| / |x - 5|

Here, we multiply both sides of the inequality by |x - 5|, which is positive for x > 0.

Simplifying further:

|1/x - 1/5| * |x - 5| / |x - 5| = |(1 - x/5)/(5x)| * |x - 5|

We notice that 1 - x/5 is less than 1, so we have:

|(1 - x/5)/(5x)| * |x - 5| < |1/(5x)| * |x - 5|

Now, we choose a value for delta such that:

|1/(5x)| * |x - 5| < epsilon

For this to hold, we set |x - 5| < 5 * epsilon, which implies:

|x - 5| < delta = 5 * epsilon

Therefore, for any epsilon > 0, we can choose delta = 5 * epsilon such that |f(x) - L| < epsilon whenever |x - 5| < delta.

In other words, as x approaches 5, the limit of 1/x is indeed 1/5.

Mathematically, we can express this as:

lim(x->5) 1/x = 1/5

The probability that the age of the victim of a canine attack was under 18 years and that the attack took place at the property of the dog owner is 49/100

Let the event of the canine attack victim being under 18 years of age be X.

Let the event of the canine attack occurring at the dog owner's property be Y.

It is given that

the probability of X or, P(X) = 80%

= 8/10

Also, P(Y) = 64%

= 64/100

P(X or Y) = 95%

or, P(X ∪ Y) = 95%

= 95/100

We need to find the probability that the victim was under 18 years old, and that the attack occurred on the dog owner's property.

= P(X and Y) = P(X ∩ Y)

We already know the probability law that

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

or, P(A ∩ B) = P(A) + P(B) - P(A ∪ B)

Henceforth,

P(X ∩ Y) = P(X) + P(Y) - P(X ∪ Y)

= 80/100 + 64/100 - 95/100

Since they have a common denominator we can write

= (80 + 64 - 95)/100

= (144 - 95) / 100

= 49/100

The solution to the system of equations is x = -1 and y = -1

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

y = -2x - 3   be equation (1)

5x = -4 + y

Adding 4 on both sides , we get

y = 5x + 4   be equation (2)

On simplifying the equations , we get

5x + 4 = -2x - 3

Adding 2x on both sides , we get

7x + 4 = -3

Subtracting 4 on both sides , we get

7x = -7

Divide by 7 on both sides , we get

x = -1

Substituting the value of x = 1 in equation (2) , we get

y = 5 ( -1 ) + 4

y = -5 + 4

y = -1
