Step-by-step explanation:

If a gallon of water contain 128 fluid ounce and a rain barrel can hold 6,400 ounce of rainwater, then the number of gallons of water that can the barrel hold is 50 gallons

A gallon of water in ounce = 128 ounce

Number of ounce of water that rain barrel can hold = 6400 ounce

To find the number of gallon of water we have to apply division

number of gallons of water that can the barrel hold = Number of ounce of water that rain barrel can hold / A gallon of water in ounce

= 6400 / 128

= 50 gallons

Hence, if a gallon of water contain 128 fluid ounce and a rain barrel can hold 6,400 ounce of rainwater, then the number of gallons of water that can the barrel hold is 50 gallons

Applying basic unitary method and time conversion, The answer is 3750 calls annually.

The unitary approach involves calculating the value of a single unit, from which we can calculate the values of the necessary number of units.

The unitary technique is used practically all the time, from problems involving speed, distance, and time to issues with estimating material costs. The technique is applied to determining a product's pricing. It is used to determine how long it takes a person or vehicle to travel a certain distance in an hour.

average length of call= 30 minutes

average travel time=30 minutes

annual working days=250

per day works 8 hours.

call hour in work = 8*60 - 30 = 450minutes.

number of calls made in those hours= 450/30=15 calls daily.

There are several different sampling methods that could be employed for this study, including:

Simple random sampling: This method involves randomly selecting a certain number of students from each campus and measuring the distance between their hometowns and their campuses.

Stratified random sampling: This method involves dividing the student population at each campus into different strata (e.g. by major or year in school) and then randomly selecting a certain number of students from each stratum.

Cluster sampling: This method involves randomly selecting a certain number of campuses and then measuring the distance between the hometowns of all students at those campuses and their respective campuses.

Multi-stage sampling: This method involves using a combination of the above methods, such as first using cluster sampling to select a certain number of campuses and then using stratified random sampling to select a certain number of students from each campus.

This study would be an enumerative study because it seeks to measure the characteristics of a population, in this case, the average distance between the hometowns of students and their campuses, by counting and measuring them.

It is not an analytic study because it doesn't involve testing a hypothesis or making causal inferences.

Solving problems involving normal proportions requires careful attention to detail, as well as a good understanding of statistical concepts such as standardization and probability.

When solving a problem where you want to find normal proportions, you can follow the following steps:

Define the problem: Clearly define the problem you are trying to solve, including any relevant details such as the population, sample size, and the variable of interest.

Check assumptions: Check if the conditions for using normal distributions are met. The data should be continuous, the sample size should be large enough, and the distribution should be approximately normal.

Calculate the sample mean and standard deviation: If you are working with a sample, calculate the sample mean and standard deviation.

Standardize the data: Convert the data into standard normal distribution, by subtracting the mean from each observation and dividing by the standard deviation.

Determine the probability: Once the data has been standardized, you can use a standard normal distribution table or a calculator to determine the probability of the variable falling within a certain range or above/below a certain value.

Interpret the results: After determining the probability, interpret the results in the context of the problem. For example, you might conclude that there is a 95% chance that a randomly selected observation falls within a certain range, or that the variable of interest is higher than a certain value in 5% of cases.

False. The total shrink for a three- and four-bend saddle is equal to that of an offset.

The statement "total shrink for a three- and four-bend saddle is twice that of an offset" is true.

1. Shrink: Shrink refers to the amount of extra conduit length needed to account for bends in the conduit, so it maintains the required distance between two points after bending.

2. Offset: An offset is a two-bend conduit configuration used to navigate around obstacles while maintaining a straight path. The total shrink for an offset can be calculated using the formula: Shrink = offset height x (multiplier for the specific angle).

3. Saddle: A saddle is a conduit configuration with either three or four bends. It is used to navigate over or under obstructions while maintaining a straight path.

4. Comparison: For both three- and four-bend saddles, the total shrink is twice that of an offset. This is because a saddle consists of two sets of bends (either two offsets or an offset and a U-bend) and requires additional conduit length to accommodate these extra bends.

In conclusion, the statement is true, as the total shrink for a three- and four-bend saddle is indeed twice that of an offset.

The limit of the ratio test for the series ∑[infinity] to n=1 10^n÷n! is infinity (∞).

The ratio test is used to determine the convergence or divergence of a series. It involves taking the limit of the absolute value of ratio of consecutive terms. If the limit is less than 1, the series converges. If the limit is greater than 1 or infinity (∞), the series diverges. If the limit is exactly 1, the test will be inconclusive.

In this case, we have f(n) = ∣(10^n+1)÷(10^n)∣ = ∣10∣ = 10. The limit of f(n) as n approaches infinity is 10.

Since the limit of f(n) is greater than 1, the series fails the ratio test. This means that the series ∑[infinity] to n=1 10^n÷n! diverges. The ratio test suggests that the series does not have a finite sum and continues indefinitely.

Step-by-step explanation:

Triangle ABC and triangle DEF are congruent, according to the Side-Angle-Side (SAS) postulate.

If the matching sides and angles of two triangles are the same length, then the triangles are said to be congruent. Congruent sides angles are what these are called.

Triangle ABC must be shown to be congruent with triangle DEF.

By demonstrating that the two triangles have a single pair of congruent sides, we can get started. We can observe that AB and DE are both 6 cm long.

The congruent angle between the two triangles can be demonstrated. As BAC and EDF are both right angles, we can see that they are equivalent.

Thus, according to the Side-Angle-Side (SAS) hypothesis Triangle ABC is consistent with triangle DEF, we can say.

The length of the considered flight in terms of time is given by: Option C. 9 hours, 45 minutes

Local time refers to the time of a particular region. The term local refers that whoever is noticing the time and calling it local time means that the person is telling about the time of the place where they're currently staying.

For this case, we're provided that:

When its 8:00 a.m. Damascus it its 4:00 pm in Vladivostok, so the time in Vladivostok is 8 hours ahead of Damascus (or 16 hours behind).

Assuming its 8 hours ahead, as the plane departs from 10:45 am from Vladivostok, and lands in Damascus at 12:30 pm, so 12:30 pm + 8 hours gives 8:30 pm in Vladivostok.

So, the plane departed at 10:45 am of Vladivostok and lands at 8:30 pm in Vladivostok, so it took 9 hours and 45 minutes for his flight to go from Vladivostok to Damascus. (since difference between 8:30 pm and 10:30 am (from 10:30 am to 8:30 pm) is of 9 hours 45 minutes)

The scatter plot has an outlier at (4, 11).

Step-by-step explanation:

For the first polynomial " \(x^2 +2x-8=(ax+b)(cx+d)\) " a=1,b=-2,c=1, and d=4.

For second polynomial "\(2x^3+2x^2-24x=2x(ax+b)(cx+d)\)" a = 1, b = -3, c = 1, and d = 4.

For the third polynomial" \(6x^2-15x-9=(ax+b)(cx+d)\) " a = 2, b = 1, c = 1, and d = -3.

In the table values of the coefficient for the first polynomial are  a=1,b=-2,c=1 so d=?.

                 \(x^2 +2x-8=(ax+b)(cx+d)\\\\ x^2 +2x-8=acx^2+(ad+bc)x+bd\)

comparing coefficients on both sides

                    ac=1 ; ad+bc=2 ;bd=8

putting values in ad+bc=2 to get the value of d.

                           (1)d+(-2)(1)=2

                               d=2+2

                                 d=4.

When the diameter is 60 mm, the rate of increase of the volume of a sphere with a radius increasing at a rate of 4 mm/s is 512π mm³/s.

Given data

Radius of a sphere, dr/dt = 4 mm/s

The diameter of the sphere, d = 60 mm

Volume of a sphere, V = 4/3πr³

We have to find the rate of growth of volume at d = 60mm.

As V = 4/3πr³

So, differentiating both sides of the above equation w.r.t time ‘t’, we get

dV/dt = 4πr² (dr/dt)

According to the given problem,

d = 60 mm⇒ radius, r = d/2 = 60/2 = 30 mm

Given, dr/dt = 4 mm/s

We have to find dV/dt, rate of growth of volume at d = 60mm.

Substitute the given values in the equation of rate of growth of volume.

dV/dt = 4πr² (dr/dt)⇒ dV/dt = 4π(30)² × 4⇒ dV/dt = 14400π mm³/s⇒ dV/dt = 45239.6 mm³/s (Approx)
