Answer:

Based on the given data, there is no evidence to support the claim that the standard deviation of the heights of women aged 25 to 34 have a different standard deviation from men aged 25 to 34

Step-by-step explanation:

The standard deviation for the heights of men aged 25 to 34, σ₀ = 2.9

The population variance, σ₀ = 2.9² = 8.41

The significance level of the test = 0.05

The number of randomly selected women in the sample, n = 16

The given heights of the 16 randomly selected women are listed as follows;

62.13, 65.09, 64.18, 66.72, 61.15, 67.50, 64.65, 63.09, 63.80, 64.21, 60.17, 68.28, 66.49, 62.10, 65.73, 64.72

By using the Mean (Average) and standard deviation of a sample formula from Microsoft Excel, we have;

The mean height of the women, [tex]\overline x[/tex] = 63.37563

The standard deviation of the variance, s₂ = 2.2 78511

The null hypothesis, H₀; σ = 2.9

The alternative hypothesis, H₀; σ ≠ 2.9

The chi-square test is given as follows;

T = (N - 1)(s/σ₀)²

Therefore, we have;

T = (16 - 1)(2.278511/2.9)² ≈ 9.2597

The critical value for the lower tail = 6.908

The critical value for the upper tail = 28.845

For the critical region, we have;

Reject H₀ if T <6.908 or T > 28.845

Therefore, given that the critical T is larger than 6.908 and less than 28.845, we fail to reject the null hypothesis, and there is not enough statistical evidence to prove that there is a difference in the standard deviation of the heights of men and women aged 25 to 34

Answer:

36 milliliters of rain.

Step-by-step explanation:

The rate at which rain accumluated in a bucket is given by the function:

[tex]r(t)=10t-t^2[/tex]

Where r(t) is measured in milliliters per minute.

We want to find the total accumulation of rain from t = 0 to t = 3.

We can use the Net Change Theorem. So, we will integrate function r from t = 0 to t = 3:

[tex]\displaystyle \int_0^3r(t)\, dt[/tex]

Substitute:

[tex]=\displaystyle \int_0^3 10t-t^2\, dt[/tex]

Integrate:

[tex]\displaystyle =5t^2-\frac{1}{3}t^3\Big|_0^3[/tex]

Evaluate:

[tex]\displaystyle =(5(3)^2-\frac{1}{3}(3)^3)-(5(0)^2-\frac{1}{3}(0)^3)=36\text{ milliliters}[/tex]

36 milliliters of rain accumulated in the bucket from time t = 0 to t = 3.

Answer:

11°

Step-by-step explanation:

If you extend the line XW at a point, say V, it forms a corresponding angle, which which be easier to find ∠X.

First we have to find what is the actual value of the corresponding angle.

180 - 102 = 78 (Angles on a straight line add up to 180°)

So now the 78° is the angle of the corresponding angle. This angle is equal to ∠X. Thus the value of x can be found.

6x + 12 = 78°

Bring 12 to the other side in order to find 'x'. This will make it to -12.

6x = 78 - 12

6x = 66

Now take 6 and put to the other side of the equation. Since 6 was multiplied with x, shifting it to the other side of the equation will make it 'divided upon 6'

x = [tex]\frac{66}{6}[/tex] = 11°

Answer:

2

Step-by-step explanation:

Because To get a single x you would have to divide 5x by 5. Whatever you do to one side you have to do to the other so you would do 5 x/5 and get 10/5 and then x=10/5 and 10/5 equals 2 so...x=2 , Hope this helped!

Answer:

  C.  96 ft³

Step-by-step explanation:

The area of the triangular base is ...

  A = 1/2bh

  A = 1/2(6 ft)(8 ft) = 24 ft²

Then the volume is ...

  V = 1/3Bh . . . . . where B is the base area and h is the height

  V = 1/3(24 ft²)(12 ft) = 96 ft³ . . . . volume of pyramid

What are the parts and functions of the brain stem?

To sum up, the brain stem is the lowest anatomical region of the brain. The brain stem is divided into three major parts; the midbrain, the pons, and the medulla. The brain stem controls the bulk of autonomic physiological functions, including respiration, heartbeat, reflexes, digestion, and sleep.

Answer:

Givn : OK = 3, OJ = 30, KN = 1, JM = 3

ON=OK+KN=3+1=4

OM=OJ+JM=30+10=40

In triangles OKJ & ONM,

OKOJ=330=110

ONOM=440=110

Angle O is common in both the triangles.

Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.

That means KJNM=110 or the two sides are parallel.

Hence ˆK=ˆN,ˆJ=ˆM corresponding angles.

Answer:

x = ± √(-15n-7) / √2n    (± (-15n-7)^(1/2) / (2n)^(1/2))

Step-by-step explanation:

Factoring?

2nx² + 15n+7 = 0

2nx² + 0*x + (15n+7) = 0  ... ax²+bx+c=0

Roots: x = (-2b ± √b²-4ac)) / 2a = (0 ± √0-4*2n*(15n+7)) / 4n

x = ± (√8n (-15n-7)) / 4n = ± (2√2n(-15n-7)) / 4n = ± (√2n(-15n-7)) / 2n

or x = ± √(-15n-7) / √2n

Answer:

Step-by-step explanation:

A rectangular prism has six sides so the area is the sum of the side areas.

A=2(xy+xz+yz) where x,y,z are the dimensions, in this case

A=2(2(6)+2(7)+6(7))

A=2(12+14+42)

A=2(68)

A=136 ft^3
