Answer:

$37

Step-by-step explanation:

To find the mean you add up all the numbers you are given and divide the result of that by the amount of numbers.

40+40+51+32+22=185

185/5=37

Answer:

(a) Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] = $24.57  

    Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] [tex]\neq[/tex] $24.57

(b) The P-value of the test statistics is 0.1212.

(c) We conclude that the population mean hourly wage in the manufacturing industry equals the population mean hourly wage in the U.S industries using P-value approach.

(d) We conclude that the population mean hourly wage in the manufacturing industry equals the population mean hourly wage in the U.S industries using critical value approach.

Step-by-step explanation:

We are given that a sample of employees from the manufacturing industry to see if the mean hourly wage differs from the reported mean of $24.57 for the U.S industries.

Suppose a sample of 30 employees from the manufacturing industry showed a sample mean of $23.89 per hour. Assume a population standard deviation of $2.40 per hour.

Let [tex]\mu[/tex] = population mean hourly wage in the manufacturing industry.

(a) Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] = $24.57     {means that the population mean hourly wage in the manufacturing industry equals the population mean hourly wage in the U.S industries}

Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] [tex]\neq[/tex] $24.57     {means that the population mean hourly wage in the manufacturing industry differs from the population mean hourly wage in the U.S industries}

The test statistics that would be used here One-sample z test statistics as we know about the population standard deviation;

                            T.S. =  [tex]\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex]  ~ N(0,1)

where, [tex]\bar X[/tex] = sample mean wage in the manufacturing industry = $23.89/hr

            σ = population standard deviation = $2.40/hr

            n = sample of employees from the manufacturing industry = 30

So, the test statistics  =  [tex]\frac{23.89-24.57}{\frac{2.40}{\sqrt{30} } }[/tex]

                                      =  -1.55

The value of z test statistics is -1.55.

(b) Now, the P-value of the test statistics is given by;

                P-value = P(Z < -1.55) = 1 - P(Z [tex]\leq[/tex] 1.55)

                              = 1 - 0.9394 = 0.0606

For two-tailed test P-value is calculated as = 0.0606 [tex]\times[/tex] 2 = 0.1212

Since, the P-value of the test statistics is higher than the level of significance as 0.1212 > 0.05, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region due to which we fail to reject our null hypothesis.

Therefore, we conclude that the population mean hourly wage in the manufacturing industry equals the population mean hourly wage in the U.S industries.

(d) Now, at 0.05 significance level the z table gives critical values of -1.96 and 1.96 for two-tailed test.

Since our test statistic lies within the range of critical values of z, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region due to which we fail to reject our null hypothesis.

Therefore, we conclude that the population mean hourly wage in the manufacturing industry equals the population mean hourly wage in the U.S industries.

Answer:

18 ft^2

Step-by-step explanation:

The area of a parallelogram is A=bh.

The area would be A = 9*4.

A = 36

To find the area of one trapezoid you divide the area of the parallelogram by 2.

Answer:

Lateral surface area of the storage shed = 336 ft²

Step-by-step explanation:

The picture is the complete question.

The shed is in the shape of a rectangular prism. The lateral surface area of the storage shed can be calculated below. The lateral area is the sides of the prism.

lateral area of a rectangular prism = 2h (l + w)

where

l = length

h = height

w = width

h = 8 ft

l = 14 ft

w = 7 ft

lateral area of a rectangular prism = 2h (l + w)

lateral area of a rectangular prism = 2 × 8 × (14 + 7)

lateral area of a rectangular prism = 16 (21)

lateral area of a rectangular prism = 336 ft²

Lateral surface area of the storage shed = 336 ft²

Answer:

The horizontal distance from the plane to the tower is 2784.5 feet.

Step-by-step explanation:

From the given question, the height of the control tower is not given. But;

Tan θ = [tex]\frac{Opposite side}{Adjacent side}[/tex]

Tan [tex]12^{0}[/tex] = [tex]\frac{x}{13100}[/tex]

x = 13100 × Tan [tex]12^{0}[/tex]

   = 2784.4910

Thus, x = 2784.5 feet

Therefore, the horizontal distance from the plane to the tower is 2784.5 feet.

Answer:

The horizontal distance from the plane to the control tower is 61630.7 ft.

Step-by-step explanation:

Here we have that

Height of flight of plane = 13,100 ft = Opposite side of angle of elevation

Angle of depression from the plane to the control tower = 12°

Therefore, the control tower can be sighted on a straight (hypotenuse) line from the plane with an angle of depression of 12°

Angle of depression from the plane to the control tower = Angle of elevation from the control tower  to the plane = 12°

Horizontal distance from the plane to the control tower = Adjacent side of the hypotenuse of the right triangle = (Opposite side of angle of elevation) ÷ (Tangent of angle of elevation)

∴ Horizontal distance from the plane to the control tower = 13,100/(tan(12°)

Horizontal distance from the plane to the control tower = 61630.7 ft. to the nearest tenth of a foot.

Answer:

[tex]x = -3+\sqrt{14} \\x=-3-\sqrt{14}[/tex]

Step-by-step explanation:

x + 6x - 5 = 0

Since you can't factor the equation, use the quadratic formula.  

Your equation is already in the form of ax + bx + c.

[tex]x=\frac{-b\frac{+}{} \sqrt{b^{2} -4ac} }{2a}[/tex]

Based on your equation  a = 1  b = 6  c = -5.  Plug in the numbers and solve for x.

[tex]x = \frac{-6\frac{+}{} \sqrt{6^{2} -4(1)(-5)} }{2(1)} \\x = \frac{-6\frac{+}{} \sqrt{36+20 } }{2} \\x=\frac{-6\frac{+}{}\sqrt{56} }{2} \\x=\frac{-6\frac{+}{}2\sqrt{14} }{2} \\\\x = -3+\sqrt{14} \\x=-3-\sqrt{14}[/tex]

Answer:

T = 2*PI* sq root (L / g)

Squaring both sides

T^2 = 4PI^2 * L/g

g = 4PI^2 * L / T^2

g = 4PI^2 * 1 / (3.27)^2

g = 39.4784176044  * 1 / 10.6929

g = 3.6920215848

(Wikipedia says 3.72076, so I'd say the calculation is correct).

Answer:

81 shares

Step-by-step explanation:

Data provided in the question

Number of shares owned = 75 shares of stock

Per share value = $50

Dividend declared = 8%

Based on the above information. the number of shares owned is

[tex]= Number\ of \ shares\ owned \times dividend\ declared\ percentage + Number\ of \ shares\ owned[/tex][tex]= 75\shares \times 8\% + 75\shares[/tex]

= 81 shares

We simply added the number of shares owned and the number of shares owned after considered the dividend declared percentage so that the correct shares owned could arrive

Answer:

Jana is expected to win 40 more games over Ty.

Step-by-step explanation:

If Ty plays the game 120 times, he is expected to win in 1/3 part of 120 games, which is ( 1/3 * 120 =) 40 games.

If Jana plays the game 120 times, she is expected to win in 2/3 part of 120 games, which is ( 2/3 * 120 =) 80 games.

If Jana is expected to win 80 times an Ty is expected to 40 times, then Jana is expected to win ( 80 - 40 =) 40 more games over Ty.

Answer:

Third answer.

Step-by-step explanation:

To simplify, we can factor 'x' from the equation, giving us:

[tex]\frac{x(1)}{x(4 + x)} = \frac{1}{x+4}[/tex]

However, we must put a domain restriction to ensure that the denominator will not equal 0. This means that 'x+ 4' cannot equal zero. Therefore, x ≠ -4.

The third answer is correct.

The Probability of an Event P(E) is that the spinner does not land on yellow is 11/7.

An experiment consists of spinning a spinner.

Red = 12

Blue = 10

Yellow = 6

We have to determine,

The experimental probability is that the spinner does not land on yellow.

The total number of spinner= 12+10+6

The total number of spinner=28.

Probability of an Event P(E) = Number of times an event occurs / Total number of trials.

The number of trials to not land on yellow is,

12+10=22

Therefore the Probability of an Event P(E) is given by,

[tex]P(E)=\frac{22}{28}[/tex]

[tex]P(E)=\frac{11}{14}[/tex]

Therefore option A is correct.
