Answer: The correct answer is 8120 foot-pound.

Step-by-step explanation:

The expression of work done in terms of mass and height is as follows;

W= mgh

Here, m is the mass of the object, g is the acceleration due to gravity and h is the height.

It is given in the problem that the work is done in lifting a 290-pound weight 28 feet in the air. Here, the work done is equal to the potential energy.

Calculate the work done.

W= mgh

Put mg=290-pound and h= 28 feet.

W= (290)(28)

W= 8120 foot-pound

Therefore, the work done is  8120 foot-pound.

The work may be calcualted as the differential of potencial energy or  as the product of the force x the distance. The result is the same.

T = weight x height

T = 290 pound * 28 feet = 8120 foot-pound

Using the information above regarding the proportion of agenda-less meetings, choose the correct conclusion for this hypothesis
ruslelena [56]

Answer: There is sufficient evidence to conclude that the proportion of agenda-less meetings is greater than 45%.

Step-by-step explanation:

Given: H_0:p=0.45 \\ H_a:p>0.45

The p-value for this hypothesis test is 0.025.

The level of significance is α=0.05

As p-value< α  ∵0.025< 0.05

[if p-value< α , we reject H_0]

then, we reject the null hypothesis.

i.e. We have sufficient evidence to support the alternative hypothesis.

Hence, the correct statement is : There is sufficient evidence to conclude that the proportion of agenda-less meetings is greater than 45%.

What is the greatest common factor of 24s3, 12s4, and 18s? <br> 3 <br> 6 <br> 3s <br> 6s
Arte-miy333 [17]

Answer:

=> 6s

Step-by-step explanation:

Given terms

24s^3  ,12s^4  and 18s

GCF consists of the common factors from all the terms whose GCF has to be found.

In order to find GCF, factors of each term has to be made:

The factors of 24s^3:

24s^3=2*2*2*3*s*s*s

The factors of 12s^4:

12s^4=2*2*3*s*s*s*s

The factors of 18s:

18s=2*3*3*s

The common factors are(written in bold):

GCF=2*3*s

=6s

So the GCF is 6s ..
