a helicopter is lifting an 800-pound unit at a rate of 200 feet per minute. how much horsepower, of work energy, is the helicopter using in the process?

Answers

Answer 1

4.84 HP is the amount of work energy used.

Given info,

A helicopter is lifting an 800-pound unit at a rate of 200 feet per minute.

1 horsepower = 550 foot-pounds per second

⇒ 800 x 200 = 160,000 foot-pounds per minute

                      = 160,000/60 foot pounds per second.

Horsepower = 160,000/60 * 550 = 428/33

                                                       = 4.848 HP

Therefore, the horsepower of work energy used is 4.84 HP

The melting point of a solid is the temperature at which is solid melts to become a liquid. The melting point of the element bromine is about 19°F. This is about 57°F more than the melting point of mercury. Which of the following equations can you use to find the melting point of mercury? What is the melting point of mercury?
x + 57 = 19
x - 57 = 19
x + 19 = 57
x + 19 = -57

how would the test statistic change for the wilcoxon rank sum test for the crickets data if the largest value in the fed group had actually been 100 hrs?

Answers

The assumptions of the two-sample t-test for comparing two population means:

1. The two samples are independent of one another.

2. The two populations have equal variance or spread.

3. The two populations are normally distributed.

The Wilcoxon test is based upon ranking the nA +nB observations of the combined sample. Each observation has a rank: the smallest has rank 1, the 2nd smallest rank 2, and so on. The wilcoxon rank-sum test statistic is the sum of the ranks for observations from one of the samples.

The Wilcoxon signed rank test is a non-paracontinuouse-level test, in contrast to the dependent samples t-test.

Wilcoxon tests have about 95% of the power of a t-test if the data really are normal, and are often far more powerful if the data is not, so just use a Wilcoxon.

The Wilcoxon test may produce misleading results if many measurements are the same value. When many values are the same, their relative ranks are the same, and this has the effect of diluting the test.

b. suppose that the population mean waist size is 85 cm and that the population standard deviation is 15 cm. how likely is it that a random sample of 277 individuals will result in a sample mean waist size of at least 86.3 cm?

Answers

The average waist size of the population is 85 cm, and the standard deviation is 15 cm. then A sample mean waist size of at least 86.3 cm has a 0.931 probability of occurring.

We can use the Z-score formula to find the probability.

Z = (86.3 - 85) / (15 / sqrt(277))

Z = 0.2 / 0.106

Z = 1.89

The probability of a sample mean waist size of at least 86.3 cm is 0.931.

What is the measure of angle A in this triangle?

Enter your answer in the box.
​ m∠A= ​

Answers

The measure of angle A in this triangle is 50°.

How to calculate the angle?

It is important to note that a triangle has three sides and the total angle is 180°.

Therefore A = 2x - 10

B = 70

C = x + 30

The angles will be illustrated thus:

2x - 10 + 70 + x + 30 = 180

3x + 90 = 180

3x = 180 - 90

3x = 90

Divide

x = 90/3

x = 30

Therefore A will be:

= 2x - 10

= 2(30) - 10

= 60 - 10

= 50°

The first step in obtaining the balance sheet is obtaining the total monthly income.

The weekly income is of $15,000, while a month is composed by four weeks, hence the monthly income is of:

4 x $15,000 = $60,000.

Then the percentages of each expenses are applied to find the values, for example, 40% of that is for employee wages, hence:

0.4 x 60,000 = $24,000.

From the percentages stated in the problem, 100% of the income is turned into expenses, hence the balance will be of zero and option C is correct.

The answer of the given question is A rectangular block of mass m has an inertia moment of Bh3/3.

What is moment of inertia?

When a body resists having the direction of its rotation along an axis changed by the application of a torque, this resistance is referred to as having moment of inertia. There are four types of axes: internal, external, fixed, and moving. It is possible to calculate the moment of inertia (I), which is always expressed in terms of that axis, by adding the results of multiplying each particle's mass by the square of its distance from the axis within the particular body. Moment of inertia is the same as mass in linear momentum when calculating the angular momentum of a rigid body.

What is a trigonometric function?

A trigonometric function indicates the relationship between angles and the lengths of sides of angles.

The specified function can be presented as follows;

Y = -4·co(5·x) - 10

There are two unknown variables

The number of equations is one

The number of equations is less than the number of unknowns, the equation is said therefore, to be undetermined.

The function, at Y = 0, can be evaluated as follows;

Y = 0 = -4·co(5·x) - 10

cos(5·x) = 10/(-4) = -2.5

5·x = arccos(-2.5) = Undefined

However, when the function is; Y = -4·cos((5·x) - 10), we get;

At Y = 0

0 = -4·cos((5·x) - 10)

cos((5·x) - 10) = 0/(-4) = 0

5·x - 10 = arccos(0) = π/2
