Step-by-step explanation:

The sound of a normal conversation 3  is  times intense than the sound of a computer.

It is the energy flow per unit area. It refers to the product of pressure and velocity of particles in a fluid medium, which is equivalent to the power received per unit area.

Let us say the sound intensity of the quietest noise a person can hear is 60 decibels. So the sound intensity of computer is 20 decibels.

Sound intensity of a normal conversation/ computer sound, will be:

[tex]SI=\frac{60}{20} =3[/tex]

Therefore, the sound of a normal conversation 3  is  times intense than the sound of a computer.

Answer:

No

Step-by-step explanation:

Substitute the x- coordinate into the equation and if the value equals the y- coordinate then it makes the equation true.

y = - 7(5) = - 35 ≠ 4

Thus (5, 4 ) does not make the equation true

Step-by-step explanation:

The trend line properly describes the data relationship in the scatterplot is plot A.

A trend line is also known as a line of best fit, and it is used to illustrate the behaviour of a set of data to assess if it is in a given pattern. So, a trend line is an analytical technique that is frequently used in conjunction with a scatter plot to determine whether or not there is a relationship between two variables.

As, per the plots.

The scatter plot A have the points distributed symmetrically on the both side of line.

Also, straights lines are negatively correlated with scatter points.

Answer:

- 1/4

Step-by-step explanation:

[tex]\frac{1-\sqrt{x} }{x^{2}-1 } = \frac{(1-\sqrt{x})*(1+\sqrt{x} ) }{(x+1)(x-1)(1+\sqrt{x} )} \\= \frac{1-x}{-(1-x)(x+1)(1+\sqrt{x} )} \\= - \frac{1}{(x+1)(1+\sqrt{x} )} \\ \lim_{->1} - \frac{1}{(x+1)(1+\sqrt{x} )} \\ = -\frac{1}{(1+1)(1+\sqrt{1}) } = - 1/4[/tex]

Using the normal distribution and the central limit theorem, it is found that there is a 0.0028 = 0.28% probability that the manufacturing line will be shut down unnecessarily.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

The probability of being shutdown is the probability of a sample mean less than 0.73 inches or more than 0.77 inches. They are the same distance to the mean(0.02), thus, considering the Central Limit Theorem:

[tex]z = \frac{0.02}{s}[/tex]

[tex]z = \frac{0.02}{0.0067}[/tex]

[tex]z = 2.99[/tex]

The probability is P(|z| > 2.99), which is 2 multiplied by the p-value of z = -2.99.

z = -2.99 has a p-value of 0.0014.

2(0.0014) = 0.0028

0.0028 = 0.28% probability that the manufacturing line will be shut down unnecessarily.

Answer: 1/2

Step-by-step explanation: it is 1/2 because the 2 points are 2 away on the x an is 1 on the y so it is 1/2.

Using the subtraction and division operation, the depth dug by the new drill, and the depth that would have been dug by the old drill are 29.05 feets and 19.37 feets respectively.

The expression for the number of feets dug by the new drill can be calculated thus :

Depth dug = 42.25 feets - 13.2 feets

Depth dug = 29.05 feets

The new drill dug 1.5 times the depth that woukd have been dug by the old drill :

Depth dug by old drill = 29.05 / 1.5

Depth dug by old drill = 19.37 feets

Therefore, the depth dug by old drill will be 19.37 feets

Answer:

  C.  Graph C

Step-by-step explanation:

All of the graphs show the boundary line with the correct slope and y-intercept. To figure which graph, you can ignore everything except "y" and the inequality symbol. That means we're looking at ...

  y >

So, the values of y that are solutions are greater than those on the boundary line. The values on the boundary line are not included. This means the shading of the solution area is above the dashed boundary line, as shown in Graph C.

Answer:

558

Step-by-step explanation:

The sum of the first n numbers is ½n(n + 1)

which is the left most number in each row number n

so finding the row containing 526

½n(n + 1) > 526

½n² + ½n > 526

n² + n > 1052

n² + n - 1052 > 0

n > (-1 + √(1² - 4(1)(-1052))) / 2(1)

n > 31.938

so 526 is almost to the end of the 32 row.

The end of that row is ½(32(33)) = 528

so 526 resides two spaces to the right of 528

The end of the row below it, row 33, is ½(33)(34) = 561

As each row is one number longer than the previous row, we count back

2 + 1 = 3 numbers from the end to find what is under 526

561 - 3 = 558
