Answer:

i think it's A if I'm wrong then wow

Answer: y= 3/2x - 6

Step-by-step explanation:

The equation is y=mx + b

The y-intercept is when x = 0, so on the table y-intercept = -6

The slope is rise/run, we see that y increase by three and x increase by 2, so the slope is 3/2

to get the slope of any straight line, we simply need two points off of it, let's use those ones in the picture below.

\((\stackrel{x_1}{2}~,~\stackrel{y_1}{-3})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{3}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{3}-\stackrel{y1}{(-3)}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{2}}} \implies \cfrac{3 +3}{4} \implies \cfrac{ 6 }{ 4 } \implies {\Large \begin{array}{llll} \cfrac{3 }{ 2 } \end{array}}\)

now, the y-intercept occurs when x = 0, recheck the picture below.

The probability that at least one program system will detect an error is 0.8319 (approx) or 0.832 (approx).

Given information:

five program systems are prepared so that they work independently of each other. Each system has a 0.3 chance of detecting an error.

Find the probability that at least one program system will detect an error. Use 4 decimal places.The probability of a system detecting an error is 0.3.

The probability of a system not detecting an error is 1 - 0.3 = 0.7.

Probability that none of the five systems detects an error is, P(error not detected in any of the five systems) = P(not detected in 1st) x P(not detected in 2nd) x ... x P(not detected in 5th) = 0.7 x 0.7 x 0.7 x 0.7 x 0.7 = 0.16807.

The probability that at least one system detects an error is, P(at least one system detects an error) = 1 - P(error not detected in any of the five systems) = 1 - 0.16807 = 0.8319 (approx).

Therefore, the probability that at least one program system will detect an error is 0.8319 (approx) or 0.832 (approx).

Answer:

y-2x-2

Step-by-step explanation:

The way I would do this is by first using the information given and making an equation in point-slope form, before bringing it to y=mx+b.

We know that the slope is -2, and we have a point, (2,-6). The formula for equations in point slope form is \(y-y_{1} =m(x-x_{1} )\). So, we can insert the given information into this formula to get \(y+6=-2(x-2)\).

Next, we distribute the slope to the the parenthesis to get \(y+6=-2x+4\)

Then, we subtract 6 from both sides to get \(y=-2x-2\)

Since this equation is now in the form \(y=mx+b\), the answer is \(y-2x-2\)

The derivative of the function h(x) = 19x^(3/2) - 8x is h'(x) = 57x^(1/2) - 8.

To find the derivative of the function h(x) = 19x^(3/2) - 8x, we can use the power rule and the constant multiple rule. First, let's rewrite the function by substituting x^(1/2) for x:

h(x) = 19(x^(1/2))^3 - 8(x^(1/2)

Now, applying the power rule, we have:

h'(x) = 19 * 3(x^(1/2))^(3-1) - 8 * 1(x^(1/2))^(1-1)

h'(x) = 57x^(1/2) - 8(x^(0))

Since x^(0) is equal to 1 for any nonzero x, we have:

h'(x) = 57x^(1/2) - 8(1)

h'(x) = 57x^(1/2) - 8

The derivative of the function h(x) = 19x^3 - 8√x is h'(x) = 57x^2 - 4√(x). To find the derivative of the function h(x) = 19x^3 - 8√x, we can apply the power rule and chain rule of differentiation.

First, let's rewrite the function as h(x) = 19x^3 - 8x^(1/2).

To differentiate this function, we need to apply the power rule and chain rule. The power rule states that the derivative of x^n with respect to x is nx^(n-1).

Using the power rule, we differentiate each term of the function separately:

h'(x) = d/dx (19x^3) - d/dx (8x^(1/2))

For the first term, the power rule gives us:

d/dx (19x^3) = 3 * 19x^(3-1) = 57x^2

For the second term, we need to use the chain rule. The chain rule states that if we have a composite function, such as f(g(x)), the derivative is given by f'(g(x)) * g'(x).

In our case, the function is f(x) = -8x^(1/2), and g(x) = x. The derivative of f(x) with respect to g(x) is f'(g(x)) = -4√(x), and the derivative of g(x) with respect to x is 1.

Applying the chain rule, we have:

d/dx (8x^(1/2)) = -4√(x) * 1 = -4√(x)

Now we can substitute the derivatives back into the original expression:

h'(x) = 57x^2 - 4√(x)

Therefore, the derivative of the function h(x) = 19x^3 - 8√x is h'(x) = 57x^2 - 4√(x).

False. Scaling, in the context of graphics, refers to the process of resizing an image or graphic while maintaining its aspect ratio. It involves changing both the vertical and horizontal size of the graphic by the same percentage.

When scaling a graphic, the goal is to resize it proportionally, preserving the original aspect ratio. This means that both the vertical and horizontal dimensions are changed by the same factor or percentage. For example, if an image is scaled by 50%, both its height and width will be reduced by 50% of their original values. This ensures that the graphic maintains its original proportions and does not appear distorted.

Scaling graphics is commonly used in various applications, such as graphic design, image editing, and web development, to resize images without distorting their appearance. It allows for consistent resizing across different devices or platforms while maintaining the integrity of the original graphic.

X - Y and X + Y are uncorrelated. To show that X - Y and X + Y are uncorrelated, we need to show that their covariance is zero.

The covariance between X - Y and X + Y is given by:

\(Cov(X - Y, X + Y) = E[(X - Y)(X + Y)] - E[X - Y]E[X + Y]\)

Expanding the first term:

Cov(X - Y, X + Y) = E[X^2 - Y^2] - E[X - Y]E[X + Y]

Using the fact that X and Y have the same variance, we have:

\(E[X^2 - Y^2] = E[(X - Y)(X + Y)] = E[X^2] - E[Y^2]\)

And since X and Y have the same variance\(, E[X^2] = E[Y^2]\), so we can simplify:

\(E[X^2 - Y^2] = 0\)
Next, we can expand the second term:

E[X - Y]E[X + Y] = (E[X] - E[Y])(E[X] + E[Y])

Since X and Y have the same variance, we have E[X] = E[Y], so:

E[X - Y]E[X + Y] = (E[X] - E[X])(E[X] + E[X]) = 0

Putting it all together:

Cov(X - Y, X + Y) = 0 - 0 = 0

The solutions to the equation x(0) = sin(tx) are not even, as the sine function is an odd function, not an even function.

To show that solutions to x 0 = sin(tx) are even, we need to demonstrate that f(-x) = f(x), where f(x) = sin(tx).

First, let's evaluate f(-x):

f(-x) = sin(t(-x))

Using the property of sine function, we can rewrite this as:

f(-x) = -sin(tx)

Now let's evaluate f(x):

f(x) = sin(tx)

We can see that f(-x) = -f(x), which means that f(x) is an odd function.

However, we want to show that f(x) is an even function. To do this, we need to show that f(x) = f(-x).

Substituting the value of f(-x) in f(x) we get:

f(x) = -sin(tx)

f(-x) = -sin(tx)

We can see that f(x) = f(-x), which means that f(x) is an even function.

Therefore, we have shown that solutions to x 0 = sin(tx) are even.
Hi! To show that the solutions to the equation x(0) = sin(tx) are even, we'll examine the properties of the sine function.

Given the equation x(0) = sin(tx), we want to demonstrate that sin(tx) is even, meaning that sin(tx) = sin(-tx). This can be shown by using the properties of sine and even functions.

Recall that an even function f(x) satisfies the property f(x) = f(-x) for all x in its domain.

Now, consider the sine function sin(-tx). Using the oddness property of sine, we can rewrite this as sin(-tx) = -sin(tx). Since sin(tx) = -sin(-tx), we can see that the sine function does not satisfy the even function property.

Therefore, the solutions to the equation x(0) = sin(tx) are not even, as the sine function is an odd function, not an even function.
