Answer:

CIM

Step-by-step explanation:

C is the 3rd letter of the alphabet, A is the 1st, and B is the 2nd.

CAB = 3,1,2

Repeating for DEK:

DEK = 4,5,11

Comparing:

4−3 = 1

5−1 = 4

11−2 = 9

BED = 2,5,4, so adding the corresponding numbers:

2+1 = 3

5+4 = 9

4+9 = 13

So the code is CIM.

Leviafan [203]

Answer:

58%

Step-by-step explanation:

We need to find what percent 290 is of 500.

percent = part/whole × 100%

percent = 290/500 × 100%

percent = 58%

Answer: 58%

Suppose that in a survey of 1,000 U.S. residents, 721 residents believed that the amount of violent television programming had i

Art [367]

Answer: 0.813

Step-by-step explanation:

Let A be the event describes the number of residents believed that the amount of violent television programming had increased over the past 10 years.

& B be the event describes the number of residents believed that the amount of violent television programming had decreased over the past 10 years.

Given : n(A)=721 ; n(B)=454 ; n(A∩B)=362

We know that ,

$n(A\cup B)=n(A)+n(B)-n(A\cap B)$

i.e. $n(A\cup B)=721+454-362=813$

Also, the total number of U.S. residents surveyed n(S)= 1,000

Then, the proportion of the 1,000 U.S. residents believed that either the amount of violent programming had increased or the overall quality of programming had decreased over the past 10 years will be :-

$P(A\cup B)=\dfrac{n(A\cup B)}{n(S)}=\dfrac{813}{1000}=0.813$

Hence, the required answer = 0.813

Harry owns a factory that makes plastic toys. Each toy is tested. If the toy is perfect, it is put into a box. The boxes are the

vlada-n [284]

Answer:

approximately 14 each hour

Step-by-step explanation:

500/100 = 5 = 1% of 500

2% of 500 = 10

500 - 10 = 490

490/36 = 13.6 or about 14

multiply 14 by the number of hours each day and you'll get the final answer

the loudness in decibels of sound is defined as 10 log I/I0, where I is the intensity of the sound in watts per square meter (W/

Oxana [17]

As the problem states, to solve this, we are going to use the equation $L= log \frac{I}{I_{0} }$
where
$L$ is the loudness in dB
$I$ is the intensity of a sound
$I_{0}$ <span>is the minimum intensity detectable by the human ear
</span>
We know for our problem that $I=1.65*10^{-2}$ ; we also now that the minimum intensity detectable by the human ear is $10^{-12)W/m^{2}$ , so $I_{0}=10^{-12}$ . Lets replace those values in our equation to find $L$ :
$L=log \frac{1.65*10^{-2} }{10^{-12}}$
$L=10.22dB$

Qe can conclude that since the explosion is under 100dB, it does not violates the regulation of the town. We used tow physical values to calculate the answer: the intensity of the sound of the explosion, $I=1.65*10^{-2}W/m^2$ , and the minimum intensity detectable by the human ear $I_{0}=10^{-12}W/m^{2}$ .
