Step-by-step explanation:

Hello there!

The following angles are corresponding angles

One of the properties of corresponding anlges is that they are congruent

That being said we can use this equation to solve for x

2x + 4 = 4x - 88

step 1 subtract 2x from each side

2x -2x cancels out

4x - 2x = 2x

now we have

4 = 2x - 88

step 2 add 88 to each side

-88 + 88 cancels out

4 + 88 = 92

now we have 92 = 2x

step 3 divide each side by 2

92 / 2 = 46

2x/2= x

we're left with x = 46

To find the probability that the flatcar derails, we need to subtract the probability of it not derailing from 1. Since the flatcar has an 80% chance of getting through without derailing.

Therefore, the answer is b. 20%.

What is the probability that both the boxcar and the flatcar get through without derailing
Since the events of the boxcar and the flatcar derailing are independent, we can multiply their probabilities together.

The boxcar has a 90% chance of getting through without derailing (0.9) and the flatcar has an 80% chance (0.8), so the probability that both get through without derailing is

0.9 * 0.8 = 0.72 or 72%.

It is proved that, for every positive integer n, there are n consecutive composite integers.

Given statement,

For every positive integer n, there are n consecutive composite integers.

Proof:

Assume that m is less than n and that both m and n are positive integers. When m is less than n,

n! = 1 ⋅ 2 ⋅ 3 ⋅ ⋅ ⋅ m ⋅ ⋅ ⋅ n,

which is to say that m is a factor of n!

So,

m + n! = m + ( 1 ⋅ 2 ⋅ 3 ⋅ ⋅ ⋅ m ⋅ ⋅ ⋅ n )

          = m ((1 ⋅ 2 ⋅ 3 ⋅ ⋅ ⋅ m ⋅ ⋅ ⋅ n) / m + 1)

Since m is a multiple of n!, n!/m is still an integer. Since the integer m is bounded between 1 and n, it follows that any number you choose up to n can divide m + n!, making it composite until the nth integer.

However, since n! contains the nth integer, the nth integer is also composite, meaning you can choose any integer between 1 and n inclusively and it will be composite.

it is important to consider the potential for intra-cluster similarity, as individuals within the same cluster may be more similar to each other than to individuals in other clusters.

A cluster sample is a sampling technique where the population is divided into clusters or groups, and a subset of clusters is selected at random to form the overall sample. In this type of sampling, all members of the selected clusters are included in the sample.

In the given example, the airline company selects 555 flights as clusters and surveys every passenger on those flights. Each flight represents a cluster, and by selecting random flights, the company includes every passenger on those selected flights in the survey.

This cluster sampling approach is suitable when each group or cluster is representative of the overall population. It is useful when it is impractical or costly to sample every individual unit within the population, but the selected clusters are expected to reflect the characteristics of the entire population.

Cluster sampling allows for more practical data collection, particularly when dealing with large populations or geographically dispersed units. However, it is important to consider the potential for intra-cluster similarity, as individuals within the same cluster may be more similar to each other than to individuals in other clusters.

Answer:

Step-by-step explanation:

Sum of all angles = 180

t + t + 10 + t +20 = 180

3t + 30 = 180

Subtract 30 from both sides

3t = 180 - 30

3t = 150

Divide both sides by 3

t = 150/3

t = 50

Exterior angles equals sum of opposite interior angles.

Exterior angle = t + t +10

                        = 50 + 50 + 10

                        = 110

Answer:

110 degrees.

Step-by-step explanation:

t + t + 10 + t + 20 = 180   ( angles in a triangle sum to 180)

3t + 30 = 180

3t = 150

t = 50

So the exterior angle = t + t + 10     (exterior angle theorem).

= 50 + 50 + 10

= 110 degrees.

math

If f(x)=2x²-5x-3 g(x)=2x²+5x+2 then (f/g)(x) = (x - 3) / (x + 2).

What is function?

In mathematics, a function is a relationship between two sets of elements, called the domain and the range, such that each element in the domain is associated with a unique element in the range.

To find (f/g)(x), we need to divide f(x) by g(x) as follows:

f(x) = 2x² - 5x - 3

g(x) = 2x² + 5x + 2

f(x) / g(x) = (2x² - 5x - 3) / (2x² + 5x + 2)

To simplify this expression, we can factor the numerator and denominator:

f(x) / g(x) = [(2x + 1)(x - 3)] / [(2x + 1)(x + 2)]

Now, we can cancel out the common factor of (2x + 1) from both the numerator and denominator:

f(x) / g(x) = (x - 3) / (x + 2)

Therefore, (f/g)(x) = (x - 3) / (x + 2).

HI MATE,

Step-by-step explanation:

THE ANSWER IS 6

The sequence {hn} defined as h0 = 5/3, h1 = 11/3, hn = 3hn-1 - 4hn-2 + 6n satisfies the given recurrence relation.

To prove that for all n ≥ 0, the sequence {hn} defined as h0 = 5/3, h1 = 11/3, hn = 3hn-1 - 4hn-2 + 6n satisfies the given recurrence relation, we can use mathematical induction.

Base case:

For n = 0, we have h0 = 5/3 which is equal to the given initial value.

For n = 1, we have h1 = 11/3 which is also equal to the given initial value.

Inductive step:

Assume that the recurrence relation holds for some k ≥ 1, i.e., hk = 3hk-1 - 4hk-2 + 6k.

We want to show that it also holds for k+1, i.e., h(k+1) = 3h(k+1)-1 - 4h(k+1)-2 + 6(k+1).

Using the recurrence relation for hk, we have:

hk+1 = 3hk - 4hk-1 + 6k+3 (by substituting k+1 for n in the given recurrence relation)

Similarly, we have:

hk = 3hk-1 - 4hk-2 + 6k (by assumption)

hk-1 = 3hk-2 - 4hk-3 + 6(k-1) (by assumption)

Substituting these values into the expression for hk+1, we get:

hk+1 = 3(3hk-1 - 4hk-2 + 6k) - 4(3hk-2 - 4hk-3 + 6(k-1)) + 6(k+1)

Simplifying the expression, we get:

hk+1 = 9hk-1 - 12hk-2 + 18k - 12hk-2 + 16hk-3 - 24(k-1) + 6(k+1)

hk+1 = 9hk-1 + 4hk-3 - 12hk-2 - 6(k-1) + 6(k+1)

hk+1 = 3(3hk-1 - 4hk-2 + 6k+1) - 4(3hk-2 - 4hk-3 + 6k) + 6(k+1)

hk+1 = 3h(k+1)-1 - 4h(k+1)-2 + 6(k+1)

This shows that the recurrence relation holds for all n ≥ 0 by mathematical induction, and hence the sequence {hn} defined as h0 = 5/3, h1 = 11/3, hn = 3hn-1 - 4hn-2 + 6n satisfies the given recurrence relation.

Information is needed to evaluate the project's financial viability, considering factors such as the initial investment, expected cash flows, cost of capital, and project duration.

To calculate the year 1 operating cash flows (OCF), we need to subtract the year 1 costs from the year 1 revenues:

OCF = Year 1 Revenues - Year 1 Costs

OCF = $192,000 - $125,000

OCF = $67,000

To find the depreciation expense in year 3, we need to determine the depreciation method. The provided information is incomplete regarding the depreciation method, so we cannot calculate the depreciation expense in year 3 without knowing the specific method.

The change in Net Working Capital (NWC) in year 2 can be determined by multiplying the Net Working Capital percentage (given as a percentage of t+1 revenues) by the year 1 revenues and subtracting the result from the year 2 revenues:

Change in NWC = (Year 2 Revenues - Net Working Capital percentage * Year 1 Revenues) - Year 1 Revenues

Without the specific Net Working Capital percentage or Year 2 Revenues values, we cannot calculate the exact change in NWC in year 2.

The net cash flow from salvage (ATSV) is calculated by multiplying the Salvage Value percentage by the Initial Cost:

ATSV = Salvage Value percentage * Initial Cost

ATSV = 28% * $390,000

ATSV = $109,200

To calculate the project's NPV, we need the cash flows for each year, the cost of capital, and the project duration. Unfortunately, the information provided does not include the cash flows for each year, so we cannot calculate the project's NPV.

Answer:

Step-by-step explanation:

The minimum sample size the SAT authors must use, assuming they want the confidence interval to be no longer than 10 points, is 196.

To calculate the minimum sample size, we can use the formula:

n = (Z * σ / E)^2

Where:

- n is the sample size

- Z is the z-value corresponding to the desired confidence level (99% in this case)

- σ is the population standard deviation

- E is the maximum desired margin of error (10 points in this case)

First, we need to find the z-value for a 99% confidence level. This corresponds to a two-tailed test, so the remaining 1% is divided equally between the two tails. Looking up the z-value from a standard normal distribution table, we find that Z ≈ 2.576.

Substituting the values into the formula:

n = (2.576 * 100 / 10)^2

n = 25.76^2

n ≈ 664.52

Since the sample size must be an integer, we round up to the nearest whole number to ensure the desired level of precision. Therefore, the minimum sample size required is 665.

Therefore, the minimum sample size the SAT authors must use, if they want the confidence interval to be no longer than 10 points, is **665**.

(d) However, it is important to note that this conclusion is specific to the sample of completed surveys and cannot be generalized to the entire population of high school students.

To make an inference about the percent of all high school students who use social media while doing schoolwork, Sofie would need a larger and more representative sample that covers a wider range of students in the online high school.

Additionally, she should consider potential biases in the sample, such as non-response bias if the students who chose not to complete the survey have different social media usage patterns compared to those who did respond.
