What is -3/8 ÷ 7/12?

Step-by-step explanation:

The product of 5 and the sum of - 2 and a number is - 20.

Solution,

Let the number be x, then

5×(-2+x)=-20

-10+5x=-20

5x=-20+10

5x=-10

x=-10/5

x=-2

Answer:

12

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Since there are n sides and each exterior angle = \(\frac{5n}{2}\) , then

n × \(\frac{5n}{2}\) = 360 ( multiply both sides by 2 to clear the fraction )

5n² = 720 ( divide both sides by 5 )

n² = 144 ( take the square root of both sides )

n = \(\sqrt{144}\) = 12

The polygon has 12 sides

Answer:

0.20x(1000/55)

Step-by-step explanation:

The rate of formation of b is also 0.135 m/s. This means that for every 0.135 meters of a that decomposes, 0.135 meters of b is formed.

The rate of formation of b can be calculated using the equation for the decomposition of a. The equation is:

rate of decomposition of a = rate of formation of b

Given that the rate of decomposition of a is 0.135 m/s, we can plug this value into the equation to find the rate of formation of b:

0.135 m/s = rate of formation of b

Therefore, the rate of formation of b is also 0.135 m/s. This means that for every 0.135 meters of a that decomposes, 0.135 meters of b is formed.

The z-probability for the condition -0.78 ≤ z  ≤ 1.16 is 66%.

A z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.

It is given that

-0.78 ≤ z  ≤ 1.16

We have to find the p-value corresponding to -0.78 ≤ z  ≤ 1.16.

This means, p(-0.78 ≤  z ≤ 1.16)

p(0.78≤ z ≤1.16) can be written as p(z ≤ 1.16) - p(z ≤ -0.78)

p(0.78≤ z ≤1.16) =  p(z ≤ 1.16) - (1-p(z ≤ 0.78))

p(0.78≤ z ≤1.16) =  p(z ≤ 1.16) -1 + p(z ≤ 0.78)

From the standard normal table,

p(z ≤ 1.16)=0.87698

p(z ≤ 0.78)=0.78230

So, p(0.78≤ z ≤1.16)= 0.87698-1+0.78230

p(0.78≤ z ≤1.16) = 0.65928≈0.66 i.e 66%

Therefore, the z-probability for the condition -0.78 ≤ z  ≤ 1.16 is 66%.

The Y-intercept is -3.

The gradient is -3/4 since it goes down 3 every 4 tiles.

Answer:

\(y=-\frac{3}{4}x -3\)

Step-by-step explanation:

Hey there!

We can form this equation in slope-intercept form

This means, we have to find the slope and the y intercept of the line

First lets find the slope

The equation for slope is \(\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\)

In order to find y and x, we need to take two points on the line

(-4, 0) and (0, -3)

x1   y1        x2  y2

Plug it in:

\(\frac{-3-0}{0-(-4)} \\\\\frac{-3}{4} \\\\-\frac{3}{4}\)

This means, the slope is -3/4

Now we have to find the y-intercept

The y-intercept is where the line intercepts the y-axis

The line intercepts the y-axis at the point (0, -3)

So now that we have the slope and the y-intercept, we can form the equation

\(y=-\frac{3}{4}x-3\)

The correct answer is D. setne 23 47. Based on the provided information, I understand that you have a comparison function in C code and its corresponding assembly code. You are asked to fill in the blanks by selecting the appropriate instructions based on the given values of a and b and the status flags SF, OF, ZF, and CF. Let's go through the options:

A. setg 47 23: This option is incorrect because setg is used to set a byte to 1 if the Greater flag (ZF=0 and SF=OF) is set, but the given values of a and b are 47 and 23, respectively, so it does not satisfy the condition for setg to be set.

B. setl 23 47: This option is incorrect because setl is used to set a byte to 1 if the Less flag (SF≠OF) is set, but the given values of a and b are 23 and 47, respectively, so it does not satisfy the condition for setl to be set.

C. sete 23 23: This option is incorrect because sete is used to set a byte to 1 if the Zero flag (ZF=1) is set, but the given values of a and b are 23 and 23, respectively, so it does not satisfy the condition for sete to be set.

D. setne 23 47: This option is correct. setne is used to set a byte to 1 if the Zero flag (ZF=0) is not set, which means the values of a and b are not equal. In this case, the given values of a and b are 23 and 47, respectively, so they are not equal, and setne should be used.

Therefore, the correct answer is D. setne 23 47

Let t be the number of times a sheet of paper is folded. At first, there will be two layers of paper since it is folded only once.

However, when the same sheet is repeatedly folded in half, the number of layers of the paper keeps increasing by two. Thus, the number of layers of the paper can be expressed as: 2, 4, 8, 16, ...., 2t. The formula for finding the number of layers of paper when the original sheet is folded l times can be expressed as:

r = 2l.

The above expression shows the number of layers when the sheet is folded l times. If we have to find the expression for the number of layers for n folds, then the formula would be:

r = 2n.

Therefore, the equation that represents the number of layers of paper that result when the original sheet of paper is folded a total of l times is r = 2l.

The quadratic formula is an equation that is used in solving problems of the nature ax²+bx+c=0.

The b² - 4ac in the quadratic formula is the discriminant that is used to determine whether the solution has a positive or negative result.

The standard form of a quadratic equation is f(x) = ax2 + bx + c.

To solve an equation of the nature -2x + 4x = 5, we would apply the quadratic formula. To use the formula, note that -2x represents a, while b is 4x and -5 = 0. This means that we would equate the equation to give: -2x² + 4x -5 = 0

The almighty formula is x = -b±√b² - 4ac

                                                         2a

Substituting the values in the equation, we will have

x = -4±√4² - 4(-2 * -5)

                    2*-2

x = -4 ±√16 - 40

                  -4

x = -4 ± -4.89

              -4

x = -4 + 1.225

34% of the data in a normal distribution is more than 1 standard deviation above the mean.

In a normal distribution, about 68% of the data falls within one standard deviation above or below the mean. This means that roughly 34% of the data falls one standard deviation above the mean.

To be more precise, we can use the empirical rule or the 68-95-99.7 rule, which states that:

Approximately 68% of the data falls within one standard deviation of the mean.

Approximately 95% of the data falls within two standard deviations of the mean.

Approximately 99.7% of the data falls within three standard deviations of the mean.

Therefore, if we assume that the normal distribution is perfectly symmetrical, we can estimate that roughly 34% of the data falls more than one standard deviation above the mean.

The property of binomial distributions is that the sum of the probabilities of successes and failures is always 1.

The correct statement is: "The sum of the probabilities of successes and failures is always 1." In a binomial distribution, each trial has only two possible outcomes, typically labeled as success and failure. The sum of the probabilities of these two outcomes is always equal to 1. This property ensures that the probabilities are mutually exclusive and exhaustive, covering all possible outcomes for each trial.

The statement "All trials are dependent" is incorrect. In a binomial distribution, each trial is assumed to be independent of the others, meaning the outcome of one trial does not affect the outcomes of subsequent trials.

The statement "The expected value is equal to the number of successes in the experiment" is not necessarily true. The expected value of a binomial distribution is equal to the product of the number of trials and the probability of success.

The value of the line integral over the given curve c is 16/5.

We are given the line integral:

l = ∫c \([x^2*y*dx + (x^2-y^2)*dy]\)

We will evaluate this integral over the given curve c, which is the arc of the parabola y=x^2 from (0,0) to (2,4).

We can parameterize this curve c as:

makefile

Copy code

x = t

y =\(t^2\)

where t goes from 0 to 2.

Using this parameterization, we can express the differential elements dx and dy in terms of dt:

dx = dt

dy = 2t*dt

Substituting these expressions into the line integral, we get:

l = \(∫c [x^2*y*dx + (x^2-y^2)*dy]\)

 = \(∫0^2 [t^2*(t^2)*dt + (t^2-(t^2)^2)*2t*dt]\)
