How can the properties of linear pairs and vertical angles help to determine the angle measures created by the intersecting lines?

Answer: 1/2

Step-by-step explanation:

1/3 = 2/6 so 2/6 + 1/6 = 3/6

3/6 = 1/2

Answer:

1/2

Step-by-step explanation:

Since we're dealing with fractions, the total fraction is 1

Mortgage =1/3

Food =1/6

Fraction of income left=x

So we equate everything above to 1

\( \frac{1}{3} + \frac{1}{6} + x = 1\)

\( \frac{1}{3} + \frac{1}{6} + x = 1 \\ lcm = 6 \\ multiply \: each \: term \: by \: 6 \\ 6 \times \frac{1}{3} + 6 \times \frac{1}{6} + 6(x) = 6(1) \)

\( = > 2(1) + 1(1) + 6x = 6 \\ 2 + 1 + 6x = 6 \\ 3 + 6x = 6\)

\(6x = 6 - 3 \\ 6x = 3 \\ x = \frac{3}{6} = \frac{1}{2} \)

Using equations, the time for the main engine 14.4 seconds and 21.6 seconds for the auxiliary engine

Let's call the time each engine takes to consume its allotted fuel supply as "t₁" for the main engine and "t₂" for the auxiliary engine.

From the first piece of information, we know:

t₁ = (2/3)t₂

From the second piece of information, we know that the combined fuel consumption time for both engines is 36 seconds:

t₁ + t₂ = 36

Now we can substitute the first equation into the second:

t₁ + (2/3)t₂ = 36

Combining like terms:

t₂ = 21.6

Finally, substituting t₂ back into the first equation:

t₁ = (2/3)(21.6) = 14.4

So the main engine alone could be fired for 14.4 seconds and the auxiliary engine alone could be fired for 21.6 seconds.

Answer:

1) both

2) Yes. It is appropriate to conclude that the health of the student affects ability to taste.

Step-by-step explanation:

Random Sampling  is done when each element of the sample has equal probability of being chosen. In both the samples of healthy and runny nose students each student has equal probability of being tested.

Random Assignment is one in which there is a control group and experimental group. The control group contains all the participants and each participant has the equal probability of being placed in the experimental group. For example in this experiment each student has equal probability of being tested with the given chocolate bar.

2) Yes. It is appropriate to conclude that the health of the student affects ability to taste.

the probability of success in healthy student is 78/154= 0.5065 = 50.65%

the probability of success in runny nose student is 44/118= 0.3729 = 37.29%

From this we see the probability of success is more in healthy students as compared to runny nose students

50.65> 37.29

Therefore it is appropriate to conclude that the health of the student affects ability to taste.

rate of change = change in y-axis / change in x-axis

Answer:

No solution.

Step-by-step explanation:

So lets solve the square root.

Sqrt(y^2 - 20 + 100) = y - 10

Sqrt(y^2 + 80 = y - 10)

Solve time.

y^2 + 80 = y - 10 (We are squaring them)

y^2 + 80 = y^2 - 20y + 100

y^2 + 80 - y^2 = y^2 - 20y + 100 - y^2 (Subtract y^2 from both sides)

80 = -20y + 100

Flip it

-20y + 100 = 80

-20y + 100 - 100 = 80 - 100 (Subtract 100 from both sides)

-20y = -20

Now divide both sides by -20

-20y/-20 = -20/-20

y = 1

The complete two-column proof that shows that ∠DBC ≅ ∠DCB using the definition of isosceles triangle is given in the image attached below.

Two sides directly opposite the two base angles of an isosceles triangle are congruent, so also are the two base angles congruent.

From the given diagram, we are told that:

AB ≅ AC and ∠BAD ≅ ∠CAD

Also, AD ≅ DA based on the reflexive property.

Thus, it implies that,

ΔBAD ≅ ΔCAD based on the SAS congruence theorem, because they have two pairs of congruent sides and one pair of congruent included angles.

Thus, since both triangles are congruent, therefore, DB = DC by CPCTC theorem.

Therefore, by the definition of isosceles triangle, ∠DBC ≅ ∠DCB.

Transferring ownership of real property (land and buildings) can happen in a variety of ways, and it is not necessarily consensual.

A transfer can occur, for example, through eminent domain, in which the government takes private property for public use and compensates the owner for its worth. Transfers can also occur through foreclosure, which occurs when a borrower fails on a loan and the lender takes control of the property.

Regardless of the conditions, the legal steps for transferring ownership usually include execution, delivery, acceptance, and recording. The signing of a legal instrument that transfers ownership is referred to as execution. The transfer of custody or control of the property to the new owner is referred to as delivery. The new owner's agreement to accept the transfer is referred to as acceptance.

The probability that a person who tests positive actually has the disease is approximately 0.194.

What exactly is probability?

Probability is a measure of an event's possibility or chance of occurring. It is stated as a number between 0 and 1, with 0 indicating an impossible event and 1 indicating a certain event. Probabilities ranging from 0 to 1 reflect occurrences that are probable but not guaranteed.

P(A) denotes the probability of an event A as the ratio of the number of possibilities that favour event A to the total number of potential outcomes. In other words, it is the number of possible outcomes for event A divided by the total number of possible outcomes.

Now,

To compute the probability that a person who tests positive actually has the disease, we can use Bayes' theorem, which states that:

P(A|B)=P(B|A)*P(A)/P(B)

where A and B are events, P(A | B) is the probability of event A when event B has occurred, P(B | A) is the probability of event B when event A has occurred, P(A)= prior probability of event A, and P(B) = prior probability of event B.

In this case, let A be the event of having the disease and B be the event of testing positive.

The incidence rate of the disease is 0.8%, which means that P(A) = 0.008.

The false negative rate is 6%, which means that P(B' | A) = 0.06 (where B' is the complement of event B, i.e., testing negative given that the person has the disease).

The false positive rate is 3%, which means that P(B | A') = 0.03 (where A' is the complement of event A, i.e., not having the disease).

We can compute P(B) using the law of total probability:

P(B) = P(B|A)*P(A) + P(B|A')*P(A')

= (1-P(B'|A))*P(A)+P(B|A')*(1-P(A))

= (1 - 0.06) * 0.008 + 0.03 * (1 - 0.008)

= 0.0328

Now we can use Bayes' theorem to compute P(A | B):

P(A | B) = P(B | A) * P(A) / P(B)

= (1 - P(B' | A)) * P(A) / P(B)

= (1 - 0.06) * 0.008 / 0.0328

= 0.194

Therefore,

                 the probability will be 0.194.

Step-by-step explanation:

Using the Central Limit Theorem, it is found that:

It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean \(\mu = p\) and standard deviation \(s = \sqrt{\frac{p(1 - p)}{n}}\), as long as \(np \geq 10\) and \(n(1 - p) \geq 10\).

The estimate and the sample size are given by:

p = 0.38, n = 168.

Hence the mean is given by:

\(\mu = p = 0.38\)

The standard error is given by:

\(s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.38(0.62)}{168}} = 0.0374\)

The value of n can be determined by finding the number of visible arcs in the pattern, which is 30 in this case.

To determine the value of n, we need to find the relationship between the total length of visible areas and the number of circles (n).

In the given pattern, each circle contributes to the visible area twice: once as its circumference and once as the overlapping part with the adjacent circles. Since the circumference of each circle is 1 unit, the visible area contributed by each circle is 2 units.

Therefore, the total length of visible areas can be expressed as 2n. Given that the total length is 60 units, we can set up the equation:

2n = 60

Solving this equation, we find:

n = 60/2 = 30

Thus, the value of n is 30.

Step-by-step explanation:

Yes, isosceles triangle ABC has a 130 angle at vertex B.

What is an isosceles triangle?

Any triangle with (at least) two equal sides is said to be an isosceles. The remaining side in the illustration has a length in addition to the two equal sides. This characteristic equates to the triangle's two angles being equal. Therefore, an isosceles triangle has two equal sides as well as two equal angles.

Here, we have

The isosceles triangle has 2 angles of the same length.

All angles in a triangle add to 180

if the angles are m∠A, m∠B, m∠C, then

either m∠A = m∠B or m∠B = m∠C or m∠A = m∠C

If we assume that vertex B is the one that has a twin then

130+130+x = 180

260+x = 180

x = -80, we can't have a negative angle measure.

so 130 must be the odd one

x+x+130 = 180

2x+130 = 180

2x = 50

x = 25

so

m∠A=m∠C=25°

let's test the 2nd answer choice

m∠A+m∠B=25+130 = 155,

Hence, isosceles triangle ABC has a 130 angle at vertex B if m∠A+m∠B=25+130 = 155.
