change decimetres into metres

length - 7.3m

Width - 4.2m

to find an area, do length times width

7.3 x 4.2 = 30.66 square metres

I hope this helped :)

Answer:

C. 30.66 square meters

Step-by-step explanation:

The equation for area is A = L × W

L = length

W = width

Because a demimeter is 1 tenth of a meter your new measurements are 7.3 and 4.2.

multiply the measurements to find the area of 30.66² meters

C) f is decreasing for x<0 because f′(x)<0 for x<0. , we can conclude that the function f is decreasing for x<0 because f′(x)<0 for x<0.

The derivative of f is f′(x)=x2−a2=(x−a)(x+a).

This implies that f′(x)<0 when x<−a or x>a. From the derivative, we can deduce that f is decreasing for x<0 because f′(x)<0 for x<0.

The derivative of the function f is f′(x)=x2−a2=(x−a)(x+a), where a is a positive constant. This means that the derivative is negative when x<−a or x>a. We can use this information to determine the behavior of the function. Since the derivative is negative when x is less than zero, we can conclude that the function f is decreasing for x<0 because f′(x)<0 for x<0.

The feasible set for this system of constraints is not convex, and the points (5, 5) and (3, 7) violate the convexity definition.

To determine whether the feasible set for each system of constraints is convex, we need to analyze the constraints individually and examine their intersection.

a) (x1)² + (x2)² > 9

This constraint represents points outside the circle with a radius of √9 = 3. The feasible set includes all points outside this circle.

b) x1 + x2 ≤ 10

This constraint represents points that lie on or below the line x1 + x2 = 10. The feasible set includes all points on or below this line.

c) x1, x2 > 0

This constraint represents points in the positive quadrant, where both x1 and x2 are greater than zero.

Now, let's analyze the intersection of these constraints:

Considering the first two constraints (a and b), we can see that the feasible set consists of all points outside the circle (constraint a) and below or on the line x1 + x2 = 10 (constraint b).

To determine whether the feasible set is convex, we need to check if any two points within the set create a line segment that lies entirely within the set.

If we consider the points (5, 5) and (3, 7), both points satisfy the individual constraints (a) and (b). However, the line segment connecting these two points, which is the line segment between (5, 5) and (3, 7), exits the feasible set since it passes through the circle (constraint a) and above the line x1 + x2 = 10 (constraint b).

Therefore, the feasible set for this system of constraints is not convex, and the points (5, 5) and (3, 7) violate the convexity definition.

Hello!!...

Where the above are given,

(a) MLE of β: (nα + y₁ + y₂ + ... + yn)/n

(b) MLE of E(Y): (nα + y₁ + y₂ + ... + yn)/n

Maximum Likelihood Estimation (MLE) is   a statistical method used to estimate the parameters of a probability distribution by maximizing the likelihood function based on observed data.

(a) The MLE of β can be found by   maximizing the likelihood function. The likelihood function for  a gamma distribution is given by  -

L(β;  y₁, y₂, ..., yn) = (1/β^nαΓ(α))ⁿ * exp(-( y₁ + y₂ + ... + yn)/β)

Taking the logarithm of the likelihood function (log-likelihood) to simplify the calculations  -

log L(β;  y₁, y₂, ..., yn) =   n*log(1/β) + nα*log(β) - n*logΓ(α) - ( y₁ + y₂ + ... + yn)/β

To find the MLE of β, we differentiate the log-likelihood with respect to β, set it equal to zero, and solve for β  -

d/dβ(log L(β;  y₁, y₂, ..., yn)) = -n/β + nα/β² + ( y₁ + y₂ + ... + yn)/β² = 0

Simplifying the equation -

-n/β + nα/β^2 + ( y₁ + y₂ + ... + yn)/β² = 0

Multiplying through by β²

-nβ + nα + ( y₁ + y₂ + ... + yn) = 0

Rearranging  whave

nβ = nα + ( y₁ + y₂ + ... + yn)

Finally, solving for β -

β = (nα +  y₁ + y₂ + ... + yn)/n

Therefore, the MLE of β is (nα +  y₁ + y₂ + ... + yn)/n.

(b) The MLE of E(Y), the expected value of Y, is simply the MLE of β.

So, the MLE of E(Y) is (nα +  y₁ + y₂ + ... + yₙ)/n.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A computer is rendering two scenes. The computer has already rendered 540 thousand pixels (kpx) of a kitchen scene and renders another 90kpx each.

Let after t minutes the scene will have the same amounts rendered.

The linear equation in one variable can be framed as:

540 + 90t = 960 + 60t

After solving the above linear equation in one variable:

90t - 60t = 960 - 540

To find the area between two z-scores, we look up the area to the right of each value and subtract the smaller area from the larger area.

The number of standard deviations from the mean is simply defined as a z score. The z-score is determined by subtracting the mean from the test value and dividing it by the standard value.

To find the area between two z-scores, we first need to find the standard normal distribution values (Z-scores) for the given values using the standard normal distribution table. Once we find the Z-scores, we can look up the area to the left of each value in the standard normal distribution table. We subtract the smaller area from the larger area to get the area between the two Z-scores.

For example,

If we want to find the area between Z = 1.5 and Z = 2.0, we would first look up the area to the left of Z = 1.5 and Z = 2.0 in the standard normal distribution table. Let's say we find that the area to the left of Z = 1.5 is 0.9332 and the area to the left of Z = 2.0 is 0.9772. To find the area between these two Z-scores, we subtract the smaller area from the larger area, which gives us:

Area between Z = 1.5 and Z = 2.0 = 0.9772 - 0.9332 = 0.0440

Therefore, the area between Z = 1.5 and Z = 2.0 is 0.0440.

Therefore, to find the area between two z-scores, we look up the area to the right of each value and subtract the smaller area from the larger area.

Brian deposited $9,808 into a savings account that compounds interest on a daily basis, at a rate of 3.78%. If we want to find out how much interest he will earn after 12 years, we can use the formula:

A = P(1 + r/n)^(nt)

where A is the amount of money after t years, P is the principal amount (which is $9,808 in this case), r is the annual interest rate (3.78% in this case), n is the number of times the interest is compounded per year (which is 365 since it compounds daily), and t is the number of years (which is 12).

So, plugging in the values we get:

A = $9,808(1 + 0.0378/365)^(365*12)

A = $9,808(1.000103972)^4380

A = $9,808(1.496812899)

A = $14,682.54

Therefore, the interest Brian will earn after 12 years is $14,682.54 - $9,808 = $4,874.54. When we round this answer to the hundredths place, we get $4,874.54.

The point on the line y = 9x + 4 closest to the point (10, 6) is (5.5, 49.5).

To find the point on the line y = 9x + 4 that is closest to the given point (10, 6), we can utilize the concept of perpendicular distance. The line y = 9x + 4 has a slope of 9, so any line perpendicular to it will have a slope of -1/9. By finding the equation of the perpendicular line passing through (10, 6), we can determine the point of intersection with the line y = 9x + 4.

The equation of the perpendicular line is y - 6 = (-1/9)(x - 10), which simplifies to y = (-1/9)x + 56/9. By setting this equation equal to y = 9x + 4 and solving for x, we find x = 5.5. Substituting this value back into either equation, we can calculate y = 49.5.

Therefore, the point on the line y = 9x + 4 closest to (10, 6) is (5.5, 49.5).

To sketch the graph of a function that has a local maximum at 6 and is differentiable at 6, we can consider a function that approaches a maximum value at 6 and has a smooth, continuous curve around that point.

In the graph, we can depict a curve that gradually increases as we move towards x = 6 from the left side. At x = 6, the graph reaches a peak, representing the local maximum. From there, the curve starts to decrease as we move towards larger x-values.

The important aspect to note is that the function should be differentiable at x = 6, meaning the slope of the curve should exist at that point. This implies that there should be no sharp corners or vertical tangents at x = 6, indicating a smooth and continuous transition in the graph.

By incorporating these characteristics into the graph, we can represent a function with a local maximum at 6 and differentiability at that point.
