Step-by-step explanation:

“Suppose we covered a large section of wall with chalkboard paint.

How would we find the area we wanted to paint?” Your student might

answer, “Measure how high and how far across, then multiply.” Then

ask, “If one quart of paint covers 65 square feet of wall, how many

quarts would we need to paint the blackboard section with 2 coats?”

Your student would multiply the area by 2 and compare that number

to 65. For example, a blackboard 8 feet wide and 5 feet high is

40 square feet, and 2 coats would be 80 square feet. One can of

paint would not be enough.

• “Suppose we put new carpet in your bedroom. How many square feet

would we need to buy? How would we figure this out?” Your student

might answer, “Measure each wall of the room and multiply. If the

room isn’t a perfect rectangle, divide it into smaller pieces that are

easier to work with.”

Getting your student involved with home projects develops useful skills for

helping around the house, finding a part-time job, and eventually being

responsible for his or her own home.

1. Inferential statistics test data significance and account for sampling error.

2. Inferential statistics assess sample statistic accuracy.

3. Mean is a univariate statistic for central tendency.

4. Significance tests evaluate null hypothesis probability.

1. True. Inferential statistics are used to make inferences about a population based on data from a sample. This includes determining if the patterns in the data are significant or can be explained by sampling error.

2. True. This is a question about the accuracy of a sample statistic, which is a type of inferential statistic.

3. True. A mean is a measure of central tendency, which is a univariate statistic. A univariate statistic is a statistic that describes a single variable.

4. The null hypothesis is false. A significance test is a statistical test that is used to determine if the null hypothesis is likely to be true. The null hypothesis is typically the hypothesis that there is no difference between two groups or that there is no effect of a treatment. If the p-value of a significance test is less than a certain threshold, such as 0.05, then we can reject the null hypothesis and conclude that the alternative hypothesis is likely to be true.

In other words, a significance test determines the probability of obtaining the observed data if the null hypothesis is true. If the probability is very low, then we can conclude that the null hypothesis is likely false.

a. The Total Accumulated value of the annuity is $17205.50

b. The Total Present value of the annuity is $6357.31

(A) To find the accumulated value of the annuity, we need to calculate the future value of each payment and sum them up. The annuity has 32 payments of $500 per period.

For the first 12 periods, the effective rate of interest is 8%. Using the formula for the future value of an ordinary annuity, which is FV = P X ((1 + r) ^ n - 1) / r, where FV is the future value, P is the payment, r is the interest rate per period, and n is the number of periods, we can calculate the accumulated value for these 12 periods:

FV1 = $500 X ((1 + 0.08) ^ 12 - 1) / 0.08= 14572.5

For the following 20 periods, the effective rate of interest is 4%. Using the same formula, we can calculate the accumulated value for these periods:

FV2 = $500 X ((1 + 0.04) ^ 20 - 1) / 0.04=2633.00

To find the total accumulated value of the annuity, we sum up the two values:

Accumulated Value = FV1 + FV2=$17205.50

(B) To find the present value of the annuity, we need to discount each payment to the present using the appropriate discount rate for each period. Since the annuity has different interest rates for the first 12 periods and the following 20 periods, we need to discount each payment separately.

For the first 12 periods, the discount rate is 8%. Using the formula for the present value of an ordinary annuity, which is PV = P * (1 - (1 + r) ^ -n) / r, where PV is the present value, P is the payment, r is the interest rate per period, and n is the number of periods, we can calculate the present value for these 12 periods:

PV1 = $500 X (1 - (1 + 0.08) ^ -12) / 0.08=$2328.31.

For the following 20 periods, the discount rate is 4%. Using the same formula, we can calculate the present value for these periods:

PV2 = $500 X (1 - (1 + 0.04) ^ -20) / 0.04=$4092.

To find the total present value of the annuity, we sum up the two values:

Present Value = PV1 + PV2=$6357.31

The size of the quarterly deposits in Shelby's RRSP account was approximately $147.40.

Let's denote the size of the quarterly deposits as \(D\). The total number of deposits made over 9 years is \(9 \times 4 = 36\) since there are 4 quarters in a year. The interest rate per period is \(r = \frac{3.50}{100 \times 12} = 0.0029167\) (3.50% annual rate compounded monthly).

Using the formula for the future value of an ordinary annuity, we can calculate the accumulated value of the RRSP fund:

\[55,000 = D \times \left(\frac{{(1 + r)^{36} - 1}}{r}\right)\]

Simplifying the equation and solving for \(D\), we find:

\[D = \frac{55,000 \times r}{(1 + r)^{36} - 1}\]

Substituting the values into the formula, we get:

\[D = \frac{55,000 \times 0.0029167}{(1 + 0.0029167)^{36} - 1} \approx 147.40\]

Therefore, the size of the quarterly deposits, rounded to the nearest cent, is approximately $147.40.

Answer:

x = 6

Step-by-step explanation:

2x + 4 = 3x - 2

2x - 3x = -2 - 4

-x = -6

x = 6

Answer:

x = 6

Step-by-step explanation:

We are given this equation:

2x + 4 = 3x - 2

And we want to evaluate the equation for x.

To do this, we need to isolate the variable (x) on one side of the equation.

We can start by putting the numbers on one side.

We can subtract 4 from both sides of the equation to start. Remember that when solving equations, whatever we do on one side of the equation, we need to do it on the other side as well.

2x + 4 = 3x - 2

     -4          -4

___________________

2x = 3x - 6

Now, let's put the variables on the other side.

Subtract 3x from both sides.

2x = 3x - 6

-3x   -3x

______________

-x = -6

Now, the numbers and variables are on different sides, however we are not done yet, as we need to take care of the negatives, as x shouldn't be negative in this case.

-x is the same as -1x, or -1 * x.

So, in order to get rid of the negatives, we can either multiply or divide both sides by -1.

Let's multiply both sides by -1.

-1(-x) = -1(-6)

x = 6

The value of x is 6.

Step-by-step explanation:

The inverse Laplace transform of F(s) is:

\(f(t) = e^(-t)\)

To find the inverse Laplace transform of each function, we need to express them in terms of known Laplace transforms. Here are the solutions for each function:

a)

\(F(s) = \large{\frac{2e^{-0.5s}}{s^2-6s+9}}\)

To find the inverse Laplace transform, we first need to factor the denominator of F(s). The denominator factors as (s - 3)². Therefore, we can rewrite F(s) as:

\(F(s) = \large{\frac{2e^{-0.5s}}{(s-3)^2}}\)

Now, we know that the Laplace transform of eᵃᵗ is 1/(s - a). Therefore, the inverse Laplace transform of

\(e^(-0.5s) \: is \: e^(0.5t).\)

Applying this, we get:

\(f(t) = 2e^(0.5t) * t \\

b) F(s) = \large{\frac{s-1}{s^2-3s+2}}\)

We can factor the denominator of F(s) as (s - 1)(s - 2). Now, we rewrite F(s) as:

\(F(s) = \large{\frac{s-1}{(s-1)(s-2)}}\)

Simplifying, we have:

\(F(s) = \large{\frac{1}{s-2}}\)

The Laplace transform of 1 is 1/s. Therefore, the inverse Laplace transform of F(s) is:

\(f(t) = e^(2t) \\

c) F(s) = \large{\frac{s-1}{s^2+s-2}}

\)

We factor the denominator of F(s) as (s - 1)(s + 2). The expression becomes:

\(F(s) = \large{\frac{s-1}{(s-1)(s+2)}}\)

Canceling out the (s - 1) terms, we have:

\(F(s) = \large{\frac{1}{s+2}}\)

The Laplace transform of 1 is 1/s. Therefore, the inverse Laplace transform of F(s) is:

\(f(t) = e^(-2t) \\

d) F(s) = \large{\frac{e^{-s}(s-1)}{s^2+s-2}}\)

We can factor the denominator of F(s) as (s - 1)(s + 2). Now, we rewrite F(s) as:

\(F(s) = \large{\frac{e^{-s}(s-1)}{(s-1)(s+2)}}\)

Canceling out the (s - 1) terms, we have:

\(F(s) = \large{\frac{e^{-s}}{s+2}}\)

The Laplace transform of

\(e^(-s) \: is \: 1/(s + 1).\)

Therefore, the inverse Laplace transform of F(s) is:

\(f(t) = e^(-t)\)

Solution

Given that the Perimeter is: 340 yards. Lenght is 91 yards

Since P = 2(L + W)

where L is the Length

W is the width

=> 340 = 2(91 + W)

=> 340 = 182 + 2W

=> 158 = 2W

Dividing both sides by 2

=> W = 79

Hence, the width is 79 yards

Answer: it would be 79yards

Step-by-step explanation: 91•2=182

340-182=158

To obtain the average rate of change from x = 3 to x = 7

We will have to obtain the corresponding values of y at the points x=3 and x=7

From the graph, we can observe that when x = 3, y = 1

also, when x = 7, y = 3

So the rate of change can be obtained by the formula:

=> change in y values/ change in x values

so let x1 =3, then y1 = 1

when x2= 7, y2 = 3

Upon substituting these values in the above equation

rate of change = 0.5

The area of the region enclosed by the curves is (3√3 - 13)/3.

To sketch the region enclosed by the given curves 4x+y^2=12, and x=y, we can begin by graphing the curves.

First, let's graph the curve 4x+y^2=12 by rewriting it in terms of y:

\(y^2 = 12 - 4x\)

This is a parabola that opens to the right and is centered at (3,0), with a width of 2√3.

Next, let's graph the line x=y, which passes through the origin at a 45-degree angle.

The region enclosed by the curves is the shaded region in the figure below:

To find the area of this region, we need to integrate with respect to x or y. Since the curves intersect at x=3, it's convenient to use vertical strips and integrate with respect to x.

The height of each strip is given by the difference between the y-coordinates of the parabola and the line at the corresponding x-value, which is:

y = √(12 - 4x) - x

The width of each strip is dx.

Thus, the area of the region is given by the integral:

S = ∫[0,3] (√(12 - 4x) - x) dx

We can simplify this integral by using the substitution u = 12 - 4x, du/dx = -4:

S = ∫[0,3] (√u - 3 + u/4) (-du/4)

S = ∫[0,12] (√u - 3 + u/4) (-du/4) (by extending the limits of integration)

S = [\(-u^{(3/2)/6} - 3u/4 + u^{2/32\)]_[0,12]

S = (3√3 - 13)/3

Step-by-step explanation:

for example, Sum of 5 no. = 7×5=35

Sum of 8 no. = 8.5×8=68

Sum of added all three no. = 68 - 35 = 33

average of three new numbers = 33/3=11
