Answer:

3400 ft-lbs

Step-by-step explanation:

The Workdone in lifting the rope :

Number of feet = x

Distance = 25 feets

2.5x + 35

Taking the integral :

∫2.5x + 35 dx at x = 40

Integrating, we have :

1/2(2.5x² ) + 35x at x = 40

1/2(2.5(40)²) + 35(40)

1/2(4000) + 1400

2000 + 1400

= 3400

Hence, Workdone in lifting the rope = 3400 ft-lbs

Answer:

option 3

hope youre online exam will be easy

Step-by-step explanation:

Answer:

x = 14

y = 23

Step-by-step explanation:

x = first number

y = second and greater number

x + y = 37 ⇒ y = 37 - x

y + 5 = 2x

Substitution:

(37 - x) + 5 = 2x

42 - x = 2x

3x = 42

x = 14

y = 37 - (14)

y = 23

Answer:

29+31+24+30+20+18+16= 168

168/7= 1,176

The mean is= 1,176

Hope this helped

Answer:

24

Step-by-step explanation:

Add up all the numbers

16+18+20+24+29+30+31=168

Answer:

[tex]m = - 28[/tex]

Step-by-step explanation:

[tex] \frac{ - 3}{7} m = 12[/tex]

[tex] \frac{ - 7}{3} ( \frac{ - 3}{7})m = \frac{ - 7}{3} \times 12[/tex]

[tex] \frac{ - 1}{3} ( - 3)m = \frac{ - 7}{3} \times 12[/tex]

[tex] - 1( - 1)m = \frac{ - 7}{3} \times 12[/tex]

[tex]1 \times m = \frac{ - 7}{3} \times 12[/tex]

[tex]m = \frac{ - 7}{3} \times 12[/tex]

[tex]m = \frac{ - 7}{3} \times 12[/tex]

[tex]m = \frac{ - 7}{3} (3 \times 4)[/tex]

[tex]m = - 28[/tex]

Answer:

There is sufficient evidence. A further explanation is provided below.

Step-by-step explanation:

According to the question,

The alternative as well as null hypothesis will be:

[tex]H_0:\mu = 16[/tex]

[tex]H_a:\mu>16[/tex]

The test statistics will be:

⇒ [tex]z = \frac{\frac{\bar x - \mu}{\sigma} }{\sqrt{n} }[/tex]

By putting the values, we get

⇒    [tex]=\frac{\frac{16.06-16}{0.24} }{\sqrt{96} }[/tex]

⇒    [tex]=\frac{\frac{0.06}{0.24} }{\sqrt{96} }[/tex]

⇒    [tex]=2.45[/tex]

Or,

The p-value will be:

= 0.0071

i.e.,

⇒ [tex]p-value< \alpha[/tex]

Thus the above is the correct answer.

Answer:

√34

Step-by-step explanation:

Answer:

1014 cm^2

Step-by-step explanation:

A cube has 6 congruent square faces. To find the total surface area, find the surface area of one face,a nd multiply it by 6.

SA = 6s^2

SA = 6(13 cm)^2

SA = 6(169 cm^2)

SA = 1014 cm^2

Answer:

w(-4.2) = 3(-4.2) -1 = -12.6 - 1 = -13.6

Step-by-step explanation:

The w(-4.2) is your t so you substitute it in your expression which means you get 3(-4.2) -1 and that gives you -13.6.

Answer:

66.667 cakes

Step-by-step explanation:

The expected count or value in a goodness of fit test is the product of the expected percentage and the total count or sample size.

Since the samples are being treated as a random sample, hence, the expected percentage of each of cake, pastries and cookies is the same.

The expected count of cakes is :

100/3 % * sample size

33.3333% * 200

= 66.667 cakes
