The intersection points of the two conics are therefore[tex](1 + √14, -1 + √14)[/tex]and [tex](1 - √14, -1 - √14).[/tex]Hence, the two conics intersect at two points.

The point or points of intersection and the number of places the following 2 conic intersect is to be determined. The system over the real numbers for [tex]x² + y² = 34 and 3x - 3y = 6[/tex] is to be solved.

To determine how many points the following 2 conic intersect at, the two equations must be solved simultaneously. The points of intersection can then be determined by substituting the value of x or y into the other equation and solving for the remaining variable.The equation 3x - 3y = 6 is the equation of a straight line. Solving the equation for y, [tex]y = x - 2[/tex].

So the line passes through the point (0, -2) and (2, 0) on the x-axis. Now, substitute the value of y into the equation x² + y² = 34 to get[tex]x² + (x - 2)² = 34[/tex], expanding this gives 2x² - 4x - 26 = 0, which simplifies to x² - 2x - 13 = 0.The solution to the quadratic equation [tex]x² - 2x - 13 = 0[/tex] is given as[tex]x = 1 + √14, 1 - √14[/tex].

The following equations will have the same value of x as the one provided:

(B) 18x - 9 = 72; (D) 3(6x - 3) = 72; (E) x = 4.5

A mathematical statement that uses the word "equal to" between two expressions with the same value is called an equation.

Like 3x + 5 = 15, for instance.

Equations come in a wide variety of forms, including linear, quadratic, cubic, and others.

So, the given equation is:

3/5(30x-15)=72

Now, we have:
3/5 * 30x - 3/5 * 15 = 72

18x - 9 = 72

Using common 3 as an example, we have the following on the left side of the equation:

3(6x-3) = 72

6x-3 = 72/3

6x-3 = 24

6x = 24+3

6x = 27

x = 27/6

x = 9/2

x = 4.5

Therefore, the following equations will have the same value of x as the one provided:

(B) 18x - 9 = 72; (D) 3(6x - 3) = 72; (E) x = 4.5

The probability that Mark selects a car key or door key from the key ring is 0.3 or 30%.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Probability theory provides a framework for understanding random events and the laws of chance, and it is an important tool for modeling and simulating complex systems.

Calculating the probability that he selects a car key or door key :

In this context, we are asked to find the probability of Mark selecting a car key or door key from the key ring. To calculate this probability, we need to first determine the total number of keys on the key ring and then count the number of car keys and door keys.

Total number of keys = 10

Number of car keys = 2

Number of door keys = 1

The probability of selecting a car key or door key can be found by adding the probability of selecting a car key to the probability of selecting a door key. Since there is only one door key and two car keys, the probability of selecting a car key is higher, and we can simplify the calculation by finding the probability of selecting a car key and then adding the probability of selecting a door key that hasn't already been selected.

Probability of selecting a car key = 2/10 = 0.2

Probability of selecting a door key = 1/9 (since one key has already been selected) = 0.1111...

Therefore, the probability of Mark selecting a car key or door key from the key ring is 0.2 + 0.1111... ≈ 0.3 or 30%.

From the given information provided, the value of fog(3) and fog(4) is 0.971 and 27/40 respectively.

a) To find fog(3), we first need to find g(3) and then evaluate f(g(3)).

To find g(3), we substitute x=3 into the formula for g(x):

g(3) = (5(3) - 2)/(3 + 2) = 13/5

Now, we can evaluate f(g(3)) by substituting g(3) into the formula for f(x):

f(g(3)) = f(13/5) = 3(13/5)² / (4(13/5)² + 4) = 0.971

Therefore, fog(3) = 0.971.

b) To find fog(4), we follow the same process. First, we find g(4):

g(4) = (5(4) - 2)/(4 + 2) = 18/6 = 3

Now, we can evaluate f(g(4)) by substituting g(4) into the formula for f(x):

f(g(4)) = f(3) = 3(3)² / (4(3)² + 4) = 27/40

Therefore, fog(4) = 27/40.

The probability that a randomly selected loan application takes longer than 11 days to process is 0.1587.

The time taken to process a loan application is uniformly distributed between 5 and 17 days.

We need to determine the probability that a random loan application takes longer than 11 days to process.

To compute the probability, we'll first determine the distribution's parameters;

we have:  a = 5 (minimum value)b = 17 (maximum value)

Mean: μ = (a+b) / 2 = (5+17) / 2 = 11

Variance: σ2 = (b-a)2/12

                     = (17-5)2/12

                     = 12.3333Standard deviation:  

                 σ = 3.516

For the problem, we want to find the probability of a loan application taking more than 11 days to be processed.

In other words, we want to find the probability of the application taking more than one standard deviation from the mean, that is, P(X > μ + σ).

Since the distribution is symmetric, we can also find the probability by calculating P(X < μ - σ) and subtracting the result from 1, since the total probability must be 1.

Using the above formula, we have:

P(X > μ + σ) = P(X > 11 + 3.516)

                  = P(X > 14.516)

To standardize the value of 14.516, we'll convert it to a z-score, which is z = (X - μ) / σ.

Therefore, we have z = (14.516 - 11) / 3.516 = 1

Since we are dealing with a standard normal distribution, we can use the standard normal distribution table to find the probability associated with z = 1.

From the table, we find that the probability of z being less than 1 is 0.8413;

thus, the probability of z being greater than 1 is 1 - 0.8413 = 0.1587.

Answer:

Step-by-step explanation:

The distance from point A to point B is approximately 1363.7 feet.

Using slope concept:

tan(θ1) = h/d

tan(θ2) = h/(d+x), where x is the distance from point A to the boat when Dominic measured the angle of depression at point B.

We can rearrange these equations to solve for h and x:

h = d*tan(θ1)

h = (d+x)*tan(θ2)

d*tan(θ1) = (d+x)*tan(θ2)

d*(tan(θ1)-tan(θ2)) = x*tan(θ2)

d = x*tan(θ2)/(tan(θ1)-tan(θ2))

Substituting the given values, we get:

d = x*tan(32°)/(tan(6°)-tan(32°))

Using a calculator, we can evaluate this expression to get:

d ≈ 1363.7 feet

Therefore, the distance from point A to point B is approximately 1363.7 feet.

The percentage of rents between $1,300 and $1,720 is 34.13%.

To calculate this, we need to use the z-score formula to convert the rent range into a z-score range. The z-score formula is (x-μ)/σ, where x is the rent range, μ is the mean rent and σ is the standard deviation.

To calculate the lower z-score, the formula becomes (1300-1510)/210 = -1.19.

To calculate the higher z-score, the formula becomes (1720-1510)/210 = 1.14. The z-score of -1.19 to 1.14 corresponds to 34.13% according to the z-table. Therefore, 34.13% of rents are between $1,300 and $1,720.

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x + 3" equals the number "9". The purpose of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. In the equation "x2 + 2x - 3 = 0," for example, the variable x is raised to the second power. Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.

Triangle ABC is similar to triangle DEF. The tangent of angle A is equal to 5/12 and the sine of angle F is 1/13.

The sine of the angle is the proportion of a right-angled triangle's hypotenuse to its perpendicular.

Triangle ABC and triangle DEF are similar in that their respective sides are proportional and their corresponding angles are equal. As a result, we have:

BC/EF = AC/DF = AB/DE

To determine the ratio AB/BC, we can utilise the tangent of angle A:

Tan(A) = 5/12 = AB/BC

By multiplying both sides by 12, we may make this simpler:

AB/BC = 12 tan(A).

We can now determine the ratio AB/EF using the ratio BC/EF:

AB/DE = BC/EF

This can be rearranged to yield AB/EF:

BC/EF * DE/AB = AB/EF

Due to the similarity of the triangles, we know that BC/EF = 12/13 and can therefore insert this into the equation:

(12/13) * (AB/DE) = AB/EF

Using the formula AB/DE = 5/12 (from above), we can reduce this:

AB/EF = (12/13) * (5/12) = 5/13

Finally, we may calculate the sine of angle F using the sine ratio:

sinning(F) = EF/DF

Using the ratio AB/EF that we recently discovered, we may rephrase this as follows:

sin(F) = (1/AB) * (AB/EF) = (1/AB) * (5/13)

Simplifying and substituting AB = 5k results in:

sin(F) is equal to (1/5k) x (5/13) x 1/(k*13).

We can select k = 1 because we want the response in its simplest form:

sin(F) = 1/13

As a result, 1/13 is the sine of angle F.

negative linear association

Step-by-step explanation:

The best description of the association between life expectancy and infant mortality rate in the given graph is option B. Countries with higher infant mortality rates tended to have shorter life expectancies.

The negative linear association between life expectancy and infant mortality rate in the attached graph,

Life Expectancy,

Life expectancy refers to the average number of years a person is expected to live from birth.

In the graph, life expectancy is represented on the vertical axis (y-axis).

Infant Mortality Rate,

Infant mortality rate refers to the number of deaths of infants under one year of age per 1,000 live births.

In the graph, the infant mortality rate is represented on the horizontal axis (x-axis).

Negative Linear Association,

A negative linear association means that as one variable increases, the other variable tends to decrease at a consistent rate.

here, as the infant mortality rate increases (moving right on the x-axis), the life expectancy tends to decrease (moving down on the y-axis).

Interpretation,

Looking at the graph, we can see that countries with higher infant mortality rates are positioned towards the right side of the graph,

and they tend to have shorter life expectancies, which are positioned towards the bottom of the graph.

Conversely, countries with lower infant mortality rates are positioned towards the left side of the graph, and they tend to have longer life expectancies,

which are positioned towards the top of the graph.

Implication,

The negative linear association in the graph indicates that countries with higher rates of infant mortality are likely to have lower life expectancies.

This is because higher infant mortality rates often indicate poorer healthcare systems, lower living standards,

and other factors that can impact life expectancy negatively.

Therefore, based on the graph's trend, we can conclude that the statement B is the best description of the association between life expectancy and infant mortality rate.

The length of the shadow of the second pole is 75 meters, was solved by using the concept of similar triangles.

The concept of similar triangles is based on the idea that if two triangles have the same shape but different sizes, they are called similar triangles. This means that their corresponding angles are equal and their corresponding sides are in proportion.

A triangle is a 2-dimensional geometric shape with three sides, three angles, and three vertices. It is one of the basic shapes in geometry and is used to describe many real-world objects and phenomena.

In the given question,

Length of shadow of first pole / Height of first pole = Length of shadow of second pole / Height of second pole

Substituting the given values, we get:

20√3 / 20 = x / 25√3

Simplifying, we get:

x = (20√3 / 20) * 25√3

x = 25*3

x = 75

6/8 + 4/8 + 2/8 + 4/8 = 16/8 = 2 hours

Since there are four days she worked out, to find out how much time she should work out each day, we can divide the total time by four:

2 hours ÷ 4 = 0.5 hours

Therefore, June should work out for 0.5 hours, or 30 minutes, each day to spend an even amount of time working out.

The probability that the arborist will break a saw chain on a day in which he spends 1/2 of his time climbing, 3/8 limbing, and 1/8 felling and bucking is 0.007

We are given the probabilities of an arborist breaking a saw chain in a day's work are 0.004 for a small climbing saw, 0.008 for a medium limbing saw, and 0.04 for a large felling and bucking saw.

The time that he spends on each saw are 1/2 of his time climbing, 3/8 limbing, and 1/8 felling and bucking.

Let us find the probability that he will break a chain when he uses the small climbing saw.

P(small climbing saw) = 1/2P(Break a chain using small climbing saw) = 0.004

Using the medium limbing saw: P(medium limbing saw) = 3/8P(Break a chain using medium limbing saw) = 0.008

Using the large felling and bucking saw: P(large felling and bucking saw) = 1/8P(Break a chain using large felling and bucking saw) = 0.04

Now, to find the probability that he will break a chain on a day, we use the weighted average. Probability is a weighted average because the probability of breaking the saw chain is different for each saw that he uses.

Hence, the probability that he breaks a saw chain when he uses each saw is weighted according to how much time he spends on that saw.

P = P(small climbing saw)* P(Break a chain using small climbing saw) + P(medium limbing saw) * P(Break a chain using medium limbing saw) + P(large felling and bucking saw) * P(Break a chain using large felling and bucking saw)P = (1/2 * 0.004) + (3/8 * 0.008) + (1/8 * 0.04)P = 0.007

We can use the slope-intercept form of a linear equation to model the balance y after t months, where the slope represents the rate of change of the balance and the y-intercept represents the initial balance.

The initial balance (y-intercept) is the amount Tina borrowed to buy the refrigerator, which we don't know. But we can find the slope using the two data points provided:

Four months: balance = $630

Six months: balance = $520

The change in the balance over the two-month period is:

$520 - $630 = -$110

The slope of the line is the rate of change of the balance per month, which is:

slope = Δy/Δt = (-$110)/(6-4) = -$55/month

Using the point-slope form of a linear equation, we can plug in one of the data points to find the y-intercept:

y - 630 = -$55(t - 4)

y - 630 = -$55t + 220

y = -$55t + 850

Therefore, the equation that models the balance y after t months is:

y = -$55t + 850.
