Answer:

A)

Step-by-step explanation:

A systems of equations that are 2 completely separate lines will have 1 solution.

A systems of equations that are the same line will have infinite amount of solutions.

A systems of equation that have parallel lines will have no solution.

We see that B, C, and D are all 2 completely separate lines with their own slope and y-intercept. Therefore, they will have 1 solution.

A is our answer because we see that they have the same slope but different y-intercepts. This means that they are parallel lines and will never intersect each other, thus providing us with no solution.

The simplified answers are as follows:

a. 10³⁻¹ = 1/1000

b. 7x⁵⁻² = 7x³

c. 56x⁰ = 56

d. 100x⁴ - x² = Cannot be simplified further.

e. 8x⁸⁻¹ + 3x⁴⁻⁴ = 8x⁷ + 3

Let us discuss in a detailed way:

a. Simplifying 10³⁻¹:

10³⁻¹ can be rewritten as 10⁻³, which is equal to 1/10³ or 1/1000. So, the simplified form of 10³⁻¹ is 1/1000.

The exponent -³ indicates that we need to take the reciprocal of the base raised to the power of ³. In this case, the base is 10, and raising it to the power of ³ gives us 10³. Taking the reciprocal of 10³ gives us 1/10³, which is equal to 1/1000.

b. Simplifying 7x⁵⁻²:

The expression 7x⁵⁻² can be simplified as 7x³.

The exponent ⁵⁻² means we need to take the reciprocal of the base raised to the power of ⁵. So, x⁵⁻² becomes 1/x⁵². Multiplying 7 and 1/x⁵² gives us 7/x⁵². Since x⁵² is the reciprocal of x², we can simplify the expression to 7x³.

c. Simplifying 56x⁰:

The expression 56x⁰ simplifies to 56.

Any term raised to the power of zero is equal to 1. Therefore, x⁰ equals 1. Multiplying 56 by 1 gives us 56. Hence, the simplified form of 56x⁰ is 56.

d. Simplifying 100x⁴ - x²:

The expression 100x⁴ - x² cannot be further simplified.

In this expression, we have two terms: 100x⁴ and x². Both terms have different powers of x, and there are no common factors that can be factored out. Therefore, the expression cannot be simplified any further.

e. Simplifying 8x⁸⁻¹ + 3x⁴⁻⁴:

The expression 8x⁸⁻¹ + 3x⁴⁻⁴ can be simplified as 8x⁷ + 3.

The exponent ⁸⁻¹ means we need to take the reciprocal of the base raised to the power of ⁸. So, x⁸⁻¹ becomes 1/x⁸. Similarly, x⁴⁻⁴ becomes 1/x⁴. Therefore, the expression simplifies to 8x⁷ + 3.

Answer:

x= 12

Step-by-step explanation:

3x-12=24

add 12 on both sides to get 36

-12+12=0 and 12+24=36

making the equation 3x=36

then, divide 3 into both sides to cancel out 3 and get x

3/3=1 or x and 36/3=12x

so, x=12

Answer:

The missing number (x) is 12

3 times 12 is 36, 36-12 is 24

Step-by-step explanation:

Answer:

  (B) one

Step-by-step explanation:

You want to know how many points on the interval [0, 5] the function f(x) = e^(2x) have a slope equal to the average slope.

The instantaneous rate of change of function f(x) is its derivative:

  f'(x) = 2e^(2x)

This is a continuously increasing function (as is f(x)), so in any given interval there will be only one point that has any given slope.

The Mean Value Theorem says there is at least one point in the interval with the same slope as the average slope. The nature of the derivative tells you there is exactly one point with the same slope as the average slope.

The average rate of change on [0, 5] is ...

  AROC = (e^(2·5) -e^(2·0))/(5 -0) = (e^10 -1)/5

The instantaneous rate of change will have that value where ...

  f'(x) = 2e^(2x) = (e^10 -1)/5

  2x = ln((e^10 -1)/10)

  x = ln((e^10 -1)/10)/2 ≈ 3.84868475302

For this value of x, f'(x) = AROC

Answer: 3

Step-by-step explanation: 3 is not an option here but I think is the right answer. Any chance you missed some part of the question or are there other options available?

Because multiplying the top equation by 3 will get you the same y value which you can subtract and you can solve for x.

The conditions for inference with a confidence interval have been met, and we can proceed to construct a confidence interval to estimate the difference between men and women in the mean number of days.

What is confidence interval ?

A confidence interval is a range of values that is likely to contain the true value of a population parameter with a certain level of confidence.

To determine if the conditions for inference with a confidence interval have been met, we need to check the following assumptions:

Since the sample sizes are greater than 30 for both men and women, we can assume normality based on the Central Limit Theorem.

Also, since the samples are selected independently and randomly, the assumption of independence is met.

Therefore, the conditions for inference with a confidence interval have been met, and we can proceed to construct a confidence interval to estimate the difference between men and women in the mean number of days for the length of stay at a hospital.

The expression (-ydx+xdy) can be shown to be equal to (xy₂-x₂y), where C is the line segment joining the points (x,y) and (x₂,y₂).

To prove the equality, let's consider the line segment C, which connects the points (x,y) and (x₂,y₂). We can parametrize this line segment using a parameter t ranging from 0 to 1, such that the coordinates of any point on the line segment can be expressed as follows:

x(t) = x + (x₂ - x)t

y(t) = y + (y₂ - y)t

Now, we can differentiate x(t) and y(t) with respect to t to obtain dx/dt and dy/dt, respectively:

dx/dt = x₂ - x

dy/dt = y₂ - y

Next, let's express dx and dy in terms of dt by multiplying both sides of the equations above by dt:

dx = (x₂ - x)dt

dy = (y₂ - y)dt

Substituting these expressions into the given expression (-ydx+xdy), we get:

(-ydx+xdy) = (-y)(x₂ - x)dt + x(y₂ - y)dt

= -xy₂dt + xydt + x₂ydt - xydt

= xy₂dt - x₂ydt

Therefore, we have shown that (-ydx+xdy) is equal to (xy₂-x₂y) for the line segment C connecting the points (x,y) and (x₂,y₂).

The double exponential smoothing is an additive method. It is used to model trend and level components for the univariate times series data. So, option(d) is right one.

Additive relationships mean that you add the same number to any value of x to get the corresponding value of y, and are written as y = x + a. The basic idea behind double exponential smoothing is to introduce a term that accounts for the possibility that the series exhibits some form of trend. This slope component updates itself using exponential smoothing. ) is the trend smoothing factor. Double exponential smoothing is generally greater reliable for handling data that represents the trends compared to the single procedure. Double exponential smoothing with a linear trend. It therefore follows an additive trend (Holt's linear trend model). Therefore, option (d) is the correct choice.

The equation of the line that passes through the points (-8, 9) and (2, -6) is y = (-3 / 2)x - 3.Given two points (-8, 9) and (2, -6). We are supposed to find the equation of the line that passes through these two points.

We can find the equation of a line that passes through two given points, using the slope-intercept form of the equation of a line. The slope-intercept form of the equation of a line is given by, y = mx + b,Where m is the slope of the line and b is the y-intercept.To find the slope of the line passing through the given points, we can use the slope formula: m = (y2 - y1) / (x2 - x1).Here, x1 = -8, y1 = 9, x2 = 2 and y2 = -6.

Hence, we can substitute these values to find the slope.m = (-6 - 9) / (2 - (-8))m = (-6 - 9) / (2 + 8)m = -15 / 10m = -3 / 2Hence, the slope of the line passing through the points (-8, 9) and (2, -6) is -3 / 2.

Now, using the point-slope form of the equation of a line, we can find the equation of the line that passes through the point (-8, 9) and has a slope of -3 / 2.

The point-slope form of the equation of a line is given by,y - y1 = m(x - x1)Here, x1 = -8, y1 = 9 and m = -3 / 2.

Hence, we can substitute these values to find the equation of the line.y - 9 = (-3 / 2)(x - (-8))y - 9 = (-3 / 2)(x + 8)y - 9 = (-3 / 2)x - 12y = (-3 / 2)x - 12 + 9y = (-3 / 2)x - 3.

Therefore, the equation of the line that passes through the points (-8, 9) and (2, -6) is y = (-3 / 2)x - 3. Thus, the answer is (-3/2)x - 3.

A random variable X has a probability distribution as follows:

X = 0, 1, 2, 3

P(X) = 2k, 3k, 13k, 2k

where k is a positive constant. The probability P(X < 2.0) is 0.25.

What is random variable?

A quantity or item that depends on random events is formalised mathematically as a random variable, also known as a random quantity, aleatory variable, or stochastic variable. It is a function or mapping from potential outcomes to a quantifiable space, frequently to real numbers.

We know that probability sum of all events is 1

Therefore here sum of all probability events =P(X=0)+P(X=1)+P(X=2)+PX=3)=1

2k+3k+13k+2k=1

20k=1

k=1/20=0.05

For P(x<2)=P(X=0)+P(X=1)=2k+3k =5k=5*(1/20)=0.25

Hence the correct answer is b, 0.25
