You can decorate 6 cupcakes and your little brother can decorate 4 cupcakes.

You are 30 years old and your little brother is 20.

You each get to decorate one cupcake for every 5 years you've been alive.

To determine how many cupcakes each of you can decorate, you need to divide your age by 5 and round down to the nearest whole number.

For you: 30 ÷ 5 = 6 cupcakes

For your brother: 20 ÷ 5 = 4 cupcakes

Therefore, you can decorate 6 cupcakes and your little brother can decorate 4 cupcakes.

True. Exception reports show a greater level of detail than is included in routine reports.

Exception reports are reports that help in identifying data that does not conform to expected patterns. Exception reports show information about an exception in the data set.

This helps to identify irregularities or anomalies in data or system operations.Exception reports are used to analyze system performance, monitor resource consumption, and to detect unusual activity.

This type of report is important to identify issues or errors, where the routine reports or standard reports would not provide enough detail or insight to do so.

It provides detailed information on any unusual event or anomaly that occurred beyond the usual course of events or processes.Exception reports are generated and distributed when the data is not expected or when an event occurs that is outside of what is considered typical.

For example, a financial system might generate an exception report if a transaction is entered that exceeds the maximum allowed amount. This report would show the details of the transaction and highlight the exception.

The purpose of exception reports is to provide users with a higher level of detail than they would find in routine reports. Exception reports are used to highlight significant data, which will be used for further analysis or action.

The length of the side is 5/3 meters when the area is 225/81 square meters.

To determine the length of the side when the area is given as 225/81 square meters, we can use the formula for the area of a square:

Area = side^2

Given that the area is 225/81 square meters, we can set up the equation as follows:

225/81 = side^2

To find the length of the side, we need to solve for side. The square root of each side of the equation can be used as a starting point:

√(225/81) = √(side^2)

Simplifying,

15/9 = side

By dividing the numerator and denominator by their greatest common divisor, which is three, we may further reduce the fraction:

15/9 = (15/3) / (9/3) = 5/3

Therefore, the length of the side is 5/3 meters when the area is 225/81 square meters.

Step-by-step explanation:

To solve the given equations, let's assign variables to each equation and solve them step by step.

Let's assume:

a = x

b = y

c = z

d = w

e = v

From the given equations:

a * b = 1 -> x * y = 1 (Equation 1)

b * c = 4 -> y * z = 4 (Equation 2)

c * d = 9 -> z * w = 9 (Equation 3)

d * e = 16 -> w * v = 16 (Equation 4)

e * a = 25 -> v * x = 25 (Equation 5)

Now, let's solve the equations using substitution:

From Equation 1 (x * y = 1), we can rewrite it as y = 1/x.

Substituting y in Equation 2, we get (1/x) * z = 4, which gives us z = 4x.

Substituting z in Equation 3, we have (4x) * w = 9, which gives us w = 9/(4x).

Substituting w in Equation 4, we get (9/(4x)) * v = 16, which simplifies to v = (16 * 4x)/9.

Finally, substituting v in Equation 5, we have [(16 * 4x)/9] * x = 25.

Simplifying the equation, we get:

(64x^2)/9 = 25.

To solve for x, we can cross multiply and solve the quadratic equation:

64x^2 = 225.

Dividing both sides by 64, we get:

x^2 = 225/64.

Taking the square root of both sides, we have:

x = ±(√(225/64)).

So, x = ±(15/8).

Now, substituting the values of x in the respective equations, we can find the values of y, z, w, and v.

For x = 15/8:

y = 1/(15/8) = 8/15

z = 4 * (15/8) = 30/4 = 15/2

w = 9/(4 * (15/8)) = 9/(30/8) = 9 * (8/30) = 12/5

v = (16 * 4 * (15/8))/9 = (60/2)/9 = 60/18 = 10/3

For x = -15/8:

y = 1/(-15/8) = -8/15

z = 4 * (-15/8) = -30/4 = -15/2

w = 9/(4 * (-15/8)) = 9/(-30/8) = -9 * (8/30) = -12/5

v = (16 * 4 * (-15/8))/9 = (-60/2)/9 = -60/18 = -10/3

Therefore, the possible solutions for the variables are:

x = 15/8, y = 8/15, z = 15/2, w = 12/5, v = 10/3

or

x = -15/8, y = -8/15, z = -15/2, w = -12/5, v = -10/3.

Note: The solution includes both positive and negative values for the variables.

The given recurrence relation is an+2 + an+1 - 20an = 0, with initial values ao = 4 and a1 = -11. To solve the given recurrence relation, we'll first write down a few terms to observe a pattern.

Using the initial values, we have a0 = 4 and a1 = -11. Now, let's calculate a2 using the recurrence relation: a2 + a1 - 20a0 = a2 - 11 - 80 = a2 - 91 = 0, which implies a2 = 91. Continuing in the same manner, we can find a3, a4, and so on.

By solving the characteristic equation, we can find the general solution for the recurrence relation. In this case, the characteristic equation is \(r^2 + r - 20 = 0\). Factoring the equation, we have (r + 5)(r - 4) = 0, giving us the roots r1 = -5 and r2 = 4. Thus, the general solution for the recurrence relation is of the form \(an = A(-5)^n + B(4)^n\), where A and B are constants determined by the initial values.

Using the initial values ao = 4 and a1 = -11, we can substitute these values into the general solution and solve for A and B. This will give us the specific solution to the recurrence relation.

Answer:

It's exponential and  the fiftth option, y = 128(1/2)^x

Step-by-step explanation:

Answer:

The parametrization of the curve on the surface is

\(c(t) = [x(t) , y(t), z(t)] \equiv [\frac{\sqrt{97} }{2} cost - 4 , \frac{\sqrt{97} }{2} sint + \frac{5}{2} , 5\frac{\sqrt{97} }{2} sint -8 \frac{\sqrt{97} }{2} cost +\frac{93}{2} ]\)

Where

   \(x =  \frac{\sqrt{97} }{2} cost - 4\)

    \(y = \frac{\sqrt{97} }{2}  sint  + \frac{5}{2}\)

\(z = 5\frac{\sqrt{97} }{2} sint -8 \frac{\sqrt{97} }{2} cost +\frac{93}{2}\)

Step-by-step explanation:

From the question we are told that

The equation for the paraboloid is \(z = x^2 + y^2\)

The equation of the plane is \(8x - 5y + z -2 = 0\)

Form the equation of the plane we have that

\(z = 5y -8x +2\)

So

\( x^2 + y^2 = 5y -8x +2 \)

=> \( x^2 + 8x + y^2 -5y = 2 \)

Using completing the square method to evaluate the quadratic equation we have

\((x + 4)^2 + (y - \frac{5}{2} )^2 = 2 +(\frac{5}{2} )^2 + 4^2\)

\((x + 4)^2 + (y - \frac{5}{2} )^2 = \frac{97}{4}\)

\((x + 4)^2 + (y - \frac{5}{2} )^2 = ( \frac{\sqrt{97} }{2} )^2\)

representing the above equation in parametric form

\((x + 4) = \frac{\sqrt{97} }{2} cost\) , \((y -\frac{5}{2} ) = \frac{\sqrt{97} }{2} sin t\)

\(x = \frac{\sqrt{97} }{2} cost - 4\)

\(y = \frac{\sqrt{97} }{2} sint + \frac{5}{2}\)

So from \(z = 5y -8x +2\)

\(z = 5[\frac{\sqrt{97} }{2} sint + \frac{5}{2}] -8[ \frac{\sqrt{97} }{2} cost - 4] +2\)

\(z = 5\frac{\sqrt{97} }{2} sint + \frac{25}{2} -8 \frac{\sqrt{97} }{2} cost + 32 +2\)

\(z = 5\frac{\sqrt{97} }{2} sint -8 \frac{\sqrt{97} }{2} cost +\frac{93}{2}\)

Generally the parametrization of the curve on the surface is mathematically represented as

\(c(t) = [x(t) , y(t), z(t)] \equiv [\frac{\sqrt{97} }{2} cost - 4 , \frac{\sqrt{97} }{2} sint + \frac{5}{2} , 5\frac{\sqrt{97} }{2} sint -8 \frac{\sqrt{97} }{2} cost +\frac{93}{2} ]\)

0.529 is the probability that a student does not have a college degree.

From the information given, we know that:

The formula for conditional probability:

P(A|B) = P(A and B) / P(B)

Let A be the event of not having a college degree, and B be the event of being married. We want to find P(A).

Using these values, we can calculate:

P(college degree and B) = (1/2) * (400/850) = 0.235

P(A and B) = 310/850 - 0.235 = 0.07

Finally, we can calculate P(A) using the formula for total probability:

P(A) = 1 - P(college degree)

= 1 - (400/850)

= 0.529

Therefore, the probability that a student does not have a college degree is 0.529.

The number of packages of gift wrap and greeting cards sold is 181 and 44 respectively

Step-by-step explanation:

The computation of the number of packages of gift wrap and greeting cards sold is as follows:

Let us assume the number of packages of gift wrap be x

And, for greeting cards be y

The equation are as follows

x + y = 225 ..................(1)

We can write as

y = 225 - x

4x + 10y = $1,164 ............(2)

Now put the y value in the equation 2

4x + 10 (225 - x) = $1,164

4x + $2,250 - 10x = $1,164

-6x = $1,164 - $2,250

-6x = -$1,086

x = 181

And, y = 225 - 181
