The probability of a wheelchair not needing to be serviced for the 16 weeks of the semester is 0.230.

The exponential distribution is a continuous probability distribution that describes the time between two consecutive events that occur randomly and independently of each other. This distribution is useful in the fields of reliability, physics, and finance, among others.

The exponential distribution has a single parameter known as the scale parameter, which is denoted by lambda (λ) and is typically expressed in terms of the mean time between failures.The mean, median, and standard deviation are three of the most common summary statistics used to describe a probability distribution.

The probability of a wheelchair not needing to be serviced for the 16 weeks of the semester can also be calculated using the exponential distribution.

Mean: The mean of the exponential distribution is equal to 1/λ.λ = 1/7 = 0.143

Therefore, the mean is 1/λ = 1/0.143 = 6.993.

Median: The median of the exponential distribution is equal to ln(2)/λ.λ = 1/7 = 0.143

Therefore, the median is ln(2)/λ = ln(2)/0.143 = 4.837.

Standard deviation: The standard deviation of the exponential distribution is equal to 1/λ.λ = 1/7 = 0.143

Therefore, the standard deviation is 1/λ = 1/0.143 = 6.993.

Probability: P(X > 16) = e^(-λx)λ = 1/7 = 0.143X = 16P(X > 16) = e^(-0.143 * 16) = 0.230

Therefore, the probability of a wheelchair not needing to be serviced for the 16 weeks of the semester is 0.230.

Answer: go to cymath.com and type in your equations they will help you out :) .

Step-by-step explanation:

Oh boy, this sounds like a mess. But I'll do my best to help you out.

Question #8 is asking to classify if the following equation is a slope intercept form or not.

I'm sure you should have learned about what a slope intercept form by now but its general equation is: y = mx + b

The "y" is just a single variable and must stay at its own value (one).

Examples of slope intercept form:

y = 48x + 3

y = -65x +10

y = 9x - 5

Now having this in mind, answer the questions.

4x + 2y = 12 is NOT slope-intercept form because it has too many variables on the left side of the =.

2y = 18x + 8 is also NOT slope-intercept form because it has "2" next to the "y" and there should only be a "y" in the left side of the =.

y = 6x - 1 and y = 1/2x + 3 ARE slope-intercept form because it follows the concept structure.

Now for the other question, you need to substitute the x values to the 3x - 1 equation, solve for the equation, then set up the final coordination.

x                      3x - 1                  y                 (x,y)

-2                    3(-2) - 1               -7               (-2, -7)

-1                     3(-1) - 1                -4               (-1, -4)

0                     3(0) - 1                -1                (0, -1)

1                      3(1) - 1                  2               (1, 2)

2                     3(2) - 1                 5               (2, 5)

The bold points are to be plotted in the graph (I'm sure you know how to do that).

Answer:x=−y+16x=−y+1

Step-by-step explanation:

At x = 3, we don't have enough information to find f(3^2) or f'(3^2), so we cannot evaluate the expression for dy/dx at x = 3.

We can use the chain rule to find the derivative of y = sin(f(x^2)) with respect to x:

dy/dx = cos(f(x^2)) * d/dx[f(x^2)]

To find d/dx[f(x^2)], we can use the chain rule again:

d/dx[f(x^2)] = f'(x^2) * d/dx[x^2] = 2xf'(x^2)

So, putting it all together:

dy/dx = cos(f(x^2)) * 2xf'(x^2)

At x = 3, we don't have enough information to find f(3^2) or f'(3^2), so we cannot evaluate the expression for dy/dx at x = 3.

A specific sort of singularity of a complex-valued function of a complex variable is referred to as a pole in the field of mathematics known as complex analysis. It is the most basic kind of singularity in a certain sense.

Here,

a) h(n) = \(\left \{ {{a^{n} , 0\leq n\leq 3 } \atop {0 , otherwise} \right.\)

=> h(n) = { \(a^{0} +a^{1} +a^{2} +a^{3}\)}

b) H(z) = ∑ h(n)\(z^{-n}\) = h(0)\(z^{0}\) + h(1)\(z^{-1}\)+h(2)\(z^{-2}\)+h(3)\(z^{-3}\)

=> \(a^{0}z^{0} +a^{1}z^{-1} +a^{2}z^{-2} +a^{3}z^{-3}\)

=> 1 + \(a^{1}z^{-1} +a^{2}z^{-2} +a^{3}z^{-3}\)

=> 1 +  a/z + \(a^{2}\)/\(z^{2}\)  +  \(a^{3}\)/\(z^{3}\)  

=>   ( \(z^{3}\)   + a\(z^{2}\) + \(a^{2}\)z + \(a^{3}\) ) / \(z^{3}\)

Step-by-step explanation:

The square root of x in radical form is \(\sqrt{x}\)

In exponent form the square root of x is \(x^{\frac{1}{2} }\)

Answer:

D

Step-by-step explanation:

When you put x to a fraction for example x to the 1/2 power is the same thing as the square root of x, another example is x to 1/3 power this is the same thing as the cube root of x

Therefore x to the 1/2 power is the square root of x

Next a way to wright the square root of x is \(\sqrt{x}\)

This means that the answer is D

In order to calculate the area of the rhombus, first let's draw the diagonal BD.

This diagonal and the diagonal AC will intersect at point M, which is the midpoint of each diagonal.

Since M is midpoint of AC, we have AM = MC = 7 cm.

Sample mean in sample b to be less variable and more representative of  population mean than sample mean in sample a.

Standard error measures the variability of sample means around the population mean.

It decreases as sample size increases.

Using the formula for the standard error of the mean,

Calculate the standard errors for each sample,

Standard error of sample a

= s/√(n)

= 850/√(9)

= 283.33

Standard error of sample b

= s/√(n)

= 850/√(36)

= 141.67

Where s is the sample standard deviation

And n is the sample size.

The standard error of sample b is smaller than the standard error of sample a.

Sample mean in sample b is more likely to be closer to true population mean than sample mean in sample a.

Therefore, sample mean b is more surprising as larger sample size makes it more likely and accurately represents population mean.

84/2=42

So 42 ducks remain in the pond. Hope this helps :)

Answer:

5-(7s)

Step-by-step explanation:

The value of c that makes the equation true is c = 64, when x = 6 and y = 3.

To find the value of c that makes the equation true, we can start by simplifying both sides of the equation using exponent rules and canceling out common factors.

First, we can simplify 3√(x^3) to x√x, and 3√y to y√y, giving us:

x√x/cy^4 = x/4y(y√y)

Next, we can simplify x/4y to 1/(4√y), giving us:

x√x/cy^4 = 1/(4√y)(y√y)

We can cancel out the common factor of √y on both sides:

x√x/cy^4 = 1/(4)

Multiplying both sides by 4cy^4 gives us:

4x√x = cy^4

Now we can solve for c by isolating it on one side of the equation:

c = 4x√x/y^4

We can substitute in the values of x and y given in the problem statement (x>0 and y>0) and simplify:

c = 4x√x/y^4 = 4(x^(3/2))/y^4

c = 4(27)/81 = 4/3 = 1.33 for x = 3 and y = 3

c = 4(64)/81 = 256/81 = 3.16 for x = 4 and y = 3

c = 4(125)/81 = 500/81 = 6.17 for x = 5 and y = 3

c = 4(216)/81 = 64 for x = 6 and y = 3

Answer:

64 in²

Step-by-step explanation:

I did not ever do a problem like this, however this is the beauty of math, you can easily reverse engineer it.

Remember,

A = \(\pi r^2\)

And if we have 4 circles that means the area of one circle is 1/4th the total

So,

\(A=\frac{\pi r^2}{4}\)

Assuming that 16 is the radius squared times 4 lets ignore that squared for now because when going backwards we would get rid of the squared last as that was the first step.

\(A=\frac{16\pi }{4}=\frac{4\pi }{1}=4\pi\)

Now lets get it back to  by square rooting the 4

\(A=\sqrt4\pi =2\pi\)

The radius of one small circle is 2. Therefore; the diameter would be 4 for each. This in mind we know that two small circles diameters make up the radius of the larger circle we will multiply it by two again.

This gives us a final radius of the bigger circle of 8

Therefore, the area of the bigger circle is 8² which simplifies to 64

And a final answer of

64\(\pi\) in²

The probability for a data point is less than is 0.8413.

The probability is the measure of the likelihood of an event to happen. It measures the certainty of the event.

The mean(μ)=4

Standard deviation(σ)=1

(P<5)

From the figure, standard normal distribution curve probability which we have to find P<5

It is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

P(x=4)=x-μ/σ

=4-4/1=0

P(x=4)=50%

P(x<5)=P(x=4)+P(x=1)

=50%+34.13%

=0.8413

P(x<5)=0.8413

Therefore, the probability a data point is less than 5 is 0.8413.
