Let's assume the frequency of sound be f and wave length is w.

Given that, the frequency of sound varies inversely as the wavelength.

So, we can set up an equation as following:

f*w = k Where k= constant of variation.

Other information is, the frequency of a musical note is 276 cycles per second when the wavelength is 1.2m.

So, next step is to plug in f = 276 and w = 1.2 in the above equation to get the value of k.

276 * 1.2 = k

So, k = 331.2

Next step is to plug in k = 331.2 in the above equation. So,

f * w = 331.2

Now we need to find the wave length : w when frequency : f = 600.

Therefore,

600 * w = 331.2

w = \frac{331.2}{600}

So, w = 0.552

Hence, the wave length is 0.552 m.

Hope this helps you!.

(Hypothetical.) Suppose five measurements of the volume of a liquid yield the following data (in milliliters).
ElenaW [278]

Answer:

(48.106 ; 53.494)

Step-by-step explanation:

Given the data:

X : 52 48 49 52 53

Sample mean = ΣX / n

n = 5

Sample mean, xbar = 254 / 5 = 50.8

Standard deviation, s = 2.17 (using calculator)

The standard error (SE) : s/√n =2.17/√5 = 0.970

The degree of freedom, df = n-1

df = 5 - 1 = 4

Tscore(0.05, 4) = 2.776

Confidence interval :

Xbar ± Tscore*standard error

50.8 ± (2.776 * 0.970)

50.8 ± 2.694

Lower boundary = 50.8 - 2.694 = 48.106

Upper boundary = 50.8 + 2.694 = 53.494

(48.106 ; 53.494)

Help me with this please!!!!!!!!!!
aleksandr82 [10.1K]

Answer:

B)  (8, 0) and (-4,0)

Step-by-step explanation:

x-intercept when y = 0

so

x^2 - 4x - 32 = 0

Factors

(x - 8)(x + 4 ) = 0

x - 8 = 0; x = 8

x + 4 = 0; x = -4

(8, 0) and (-4,0)

What is the remainder of (6x3) (x + 2)?
Rina8888 [55]
 To do that you do 6*3=18 and then you have 18(x+2)  To find X we  distribute the 18

18x + 36 is what is left

Hope that helped:)
