The relationship between the intensity of sound((w)/(m^(2)))and the distance from the source of sound is represented by the equation (i)=((k)/(d^(2))).If you sit only one meter away from the stage at a rock concert the intensity of sound is about 0.1(w)/(m^(2)). If vanessa does not want the sound intensity to be more than 0.001(w)/(m^(2)) how close to the stage can she sit?

Answers

Answer:

10 m

Step-by-step explanation:

We are given that the relationship between intensity of sound and distance from the source is given by

Intensity (I)=[tex]\frac{k}{d^2}[/tex]

Where I=Intensity

d=Distance of sound from the source

If distance d=1m

Intensity, I=0.1[tex]w/m^2[/tex]

We have to find how close she can to the stage if vanessa does not want the sound intensity to be more than 0.001(w)/(m^(2)).

Using the formula

[tex]0.1=\frac{k}{1}[/tex]

[tex]k=0.1[/tex]

[tex]\frac{0.1}{d^2}\leq 0.001[/tex]

[tex]\frac{0.1}{0.001d^2}\leq 1[/tex]

[tex]\frac{0.1}{0.001}\leq d^2[/tex]

[tex]100\leq d^2[/tex]

[tex]10\leq d[/tex]

[tex]d=10 m[/tex]

Hence, she can sit 10 m away from the stage.

Find the value of x 8.5,9,7.5,6,7,x ;the mean is 8

Answers

Answer:

x= 10

Step-by-step explanation:

Mean is the sum of all values divided their number

(8.5+ 9 + 7.5 + 6 + 7 +x) /  6 = 8

(8.5+ 9 + 7.5 + 6 + 7 +x) = 8*6 = 48

(8.5+ 9 + 7.5 + 6 + 7 +x) =48

(38 +x) = 48

x= 48-38 = 10

You are taking a quiz that has 9 multiple-choice questions. If each question has 3 possible answers, how many different ways are there to answer the test?

Answers

Answer:

19 683

Step-by-step explanation:

Think of it as s lock..

A normal combination lock usually have 3 scrollwheels with 10 different positions in them.. (0 1 2 3 4 5 6 7 8 9)

The smallest number you can make is 000

and the biggest is 999

therefore there are a total number of 1000 possible combinations. (001, 002, 003 ... 134, 135, 136 ... 876, 877)

I think you get it.

Simply: 10 ^ 3 = 1000

In your question we have 9 "scroll wheels" with 3 "different positions" in them

So we simply do: 3 ^ 9 = 19 683

6+n/5=9

What is happening to the variable?


How do you solve for the variable?

Answers

Answer:

n=15

Step-by-step explanation:

(subtract 6 from both sides of the equation.)

6+n/5=9

6+n/5-6=9-6

(Now you will have to simplify.)

n/5=3

(You will have to multiply all terms by the same value to eliminate fraction denominators.)

n/5=3

5xn/5=5x3

(You will now have to simplify.)

n=15

And that's how you get your answer.

Evaluate 6 + a when a = 7. The value is​

Answers

Answer:

13

Step-by-step explanation:

6 + 7 = 13

When a = 7, the value of 6 + a is 13.

To evaluate the expression 6 + a when a = 7, we substitute the value of a into the expression:

6 + a = 6 + 7.

Now, we can simplify the expression by adding the numbers:

6 + 7 = 13.

Explanation:

In the expression 6 + a, the variable a represents an unknown value. By substituting a = 7 into the expression, we replace the variable with its corresponding value.

This allows us to perform the arithmetic calculation to find the result.

Therefore, when a = 7, the value of 6 + a is 13.

A large company states in its promotional literature that 74% of its employees have college degrees. Assume this claim is true. If 3 employees are selected at random from this company, what is the probability that at least 1 of the selected employees will not have a college degree?

A. 0.0176
B. 0.4052
C. 0.5948
D. 0.9284

Answers

Answer:it is 0.5948

Step-by-step explanation:c

The probability that at least 1 of the selected employees will not have a college degree is 0.594776.

What is Binomial distribution?

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,

[tex]P(x) = ^nC_x p^xq^{(n-x)}[/tex]

Where,

x is the number of successes needed,n is the number of trials or sample size,p is the probability of a single success, andq is the probability of a single failure.

Given that 74% of the employees have degrees, therefore, 26% of the employees have no degree.

Now, since we want at least any one of the three people selected to have a degree. Therefore, the probability of everyone having a degree can be written as,

Probability that at least any one of the three people selected to have a degree = 1 - Probability of everyone having a degree

Now, using the binomial distribution we can write,

[tex]\text{Probability} = 1 - [^3C_0\cdot(0.26)^0 \cdot (0.74)^{(3-0)}]\\\\\text{Probability} = 1 - 0.405224 = 0.594776[/tex]

Hence, the probability that at least 1 of the selected employees will not have a college degree is 0.594776.
