No, because \sqrt{244}\approx15.6 and it's an integer.

1<br> - divided by 4<br> 2
DanielleElmas [232]

1/2 divided by 4 would become 1/2 times 1/4 (Since you change the division sign into multiplication and you'd flip the 4 into 1/4), so the final answer would be 1/8

Suppose there are two types of persons: high-ability and low-ability. A particular diploma costs a high-ability person $10,000 a
tekilochka [14]

Answer:

K must be in range <u>$45000 ≤ k ≤ $53000 </u>to make this an effective screening device.

Step-by-step explanation:

In order for the screening device to be effective, the range of k must be such that, it is more than the pay of a worker without diploma. The extra amount must at least be equal to the cost of diploma

So the value of k must be in range from (35000 + 10000) to (35000 + 18000)

Hence,

<u>$45000 ≤ k ≤ $53000</u>

Which of the following is true about radiation from the sun?
bearhunter [10]
This isn't a math question and should be in the science section. However, I will still answer the question. The answer is choice B.

-------------------------------------------------------------------------------------------------------------

Here's a further breakdown

A. False. The radiation or energy from the sun can travel through air or else you wouldn't feel the sun's rays. Also, plant life wouldn't be alive without that energy going through the air.

B. True. The rays travel through a vacuum of space. If they couldn't travel through space, then the same problem comes up as in choice A: the issue of not feeling the sun's rays.

C. False. They rays have different frequencies. Because there are many wavelengths (see choice D below), this means there are different frequencies. Recall that f = 1/w where f is the frequency and w is the wavelength.

D. False. The rays are made of different wavelengths. The visible light portion is what we can see, though there is a lot more to the electromagnetic spectrum (eg: ultraviolet light). 

-------------------------------------------------------------------------------------------------------------

So once again, the answer is choice B
