The angle between u and v , after rounding is approximately 121.2 degrees.

To find the angle between two vectors, you can use the dot product formula:
u · v = ||u|| ||v|| cos(theta)
where ||u|| and ||v|| are the magnitudes of the vectors u and v, and theta is the angle between them.
First, we need to calculate the magnitudes of u and v:
||u|| = sqrt((-3)^2 + 4^2) = 5
||v|| = sqrt(7^2 + 5^2) = sqrt(74)
Next, we can calculate the dot product of u and v:
u · v = (-3)(7) + (4)(5) = -1
Now we can use the dot product formula to solve for theta:
-1 = (5)(sqrt(74)) cos(theta)
cos(theta) = -1 / (5 sqrt(74))
theta = acos(-1 / (5 sqrt(74))) ≈ 121.2 degrees

To find the median d of set M, we first need to arrange the numbers in ascending order and then determine the middle value. Set M contains the numbers 37, 45, 7, 12, 21, 22, and n. We know n is a positive integer.

First, arrange the known numbers: 7, 12, 21, 22, 37, 45. Next, consider the position of n in the sorted sequence:

1. If n ≤ 7, the sorted sequence becomes: n, 7, 12, 21, 22, 37, 45.
2. If 7 < n ≤ 12, the sorted sequence becomes: 7, n, 12, 21, 22, 37, 45.
3. If 12 < n ≤ 21, the sorted sequence becomes: 7, 12, n, 21, 22, 37, 45.
4. If 21 < n ≤ 22, the sorted sequence becomes: 7, 12, 21, n, 22, 37, 45.
5. If 22 < n ≤ 37, the sorted sequence becomes: 7, 12, 21, 22, n, 37, 45.
6. If 37 < n ≤ 45, the sorted sequence becomes: 7, 12, 21, 22, 37, n, 45.
7. If n > 45, the sorted sequence becomes: 7, 12, 21, 22, 37, 45, n.

Since there are 7 numbers in the set, the median d will be the 4th value. In all cases, the 4th value remains 21. Therefore, the value of d is 21.

how the number order goes.

Answer:= The exponent is 12

Step-by-step explanation:(9.1 × 10^9)(7.5 × 10^2)

When multiplying terms in scientific notation, we multiply the numbers in front and add the exponents

(a* 10^b) (c* 10^d) = ac * 10^(b+d)

(9.1 × 10^9)(7.5 × 10^2) = (9.1*7.5) * 10^(9+2)

                                                =68.25 * 10^11

But this is not proper scientific notation.  We can only have 1 number in front of the decimal.  We need to move the decimal 1 place to the right.  That adds 1 to the exponent.

=68.25 * 10^11  = 6.825 * 10^(11+1)

                           = 6.825 * 10^12

The exponent of the power in the scientific notation of the result of the expression (9.1 × 10^9)(7.5 × 10^2) is 12

The number is written in the form \(a \times 10^b\) where we have \(1 \leq a < 10\)

The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).

Scientific notations have some of the profits as:

Expressing the multiplication of (9.1 × 10^9)(7.5 × 10^2) in terms of scientific notation, we get:

\((9.1 0\times 10^9)(7.5 \times 10^2) = 9100000000 \times 750 = 6825000000000\\(9.1 0\times 10^9)(7.5 \times 10^2) = 6.825 \times 10^{12}\)(the exponent is 12)

Thus, the exponent of the power in the scientific notation of the result of the expression (9.1 × 10^9)(7.5 × 10^2) is 12

Answer: yes, it does fall at a constant rate. for each hour there is one inch of rainfall.

Step-by-step explanation:

if the line goes the the origin (0,0) then that means that it is a constant rate. if you look at the chart, there is number on every other line. This means that there is an odd number on the other lines. If you then go up the line for 1 hour, then you will meet at lines intersecting to get 1 inch of rainfall per hour

To draw the root locus of the given transfer function G(z) = \(K(z + 2/z^2),\)we need to determine the poles and zeros of the transfer function and their variation as K changes.

The transfer function G(z) can be rewritten as:

\(G(z) = K(1 + 2z^{-2} )\)

We can see that G(z) has one zero at z = 0 and two poles at z = ±√2.

a) Draw the root locus:

Start by marking the poles and zeros on the complex plane. The zero is at the origin (0) and the poles are at ±√2.

The root locus branches start at the poles and end at the zeros.

Determine the angles of departure from each pole and the angles of arrival at each zero. The angle of departure is given by:

∠θ = (2k + 1)π / N, where k = 0, 1, 2, ..., N-1

In this case, there are two poles, so N = 2. Thus, we have:

∠θ = (2k + 1)π / 2

For k = 0: ∠θ = π / 2

For k = 1: ∠θ = 3π / 2

The angles of departure from the poles at ±√2 are π/2 and 3π/2, respectively.

Determine the asymptotes of the root locus. The asymptotes are given by:

σ_a = (Σpoles - Σzeros) / N

In this case, since we have one zero and two poles, we have:

σ_a = (2√2 + (-√2)) / 2 = √2

The asymptotes are vertical lines parallel to the imaginary axis at Re(z) = √2.

Calculate the breakaway points, if any exist. These are the points on the real axis where the root locus branches meet and subsequently depart from.

To find the breakaway points, we set the derivative of the characteristic equation equal to zero and solve for z:

dG(z)/dz = 0

For the given transfer function G(z), the characteristic equation is:

\(1 + G(z) = 1 + K(1 + 2z^{-2} ) = 0\)

Simplifying:

\(1 + K(1 + 2/z^2) = 0\)

\(1 + K + 2K/z^2 = 0\)

Multiply through by \(z^2:\)

\(z^2 + Kz^2 + 2K = 0\)

\((z^2 + 2K) + Kz^2 = 0\)

Setting the coefficient of z^2 to zero:

K + 2 = 0

K = -2

Therefore, the breakaway point occurs at K = -2.

Draw the root locus branches. The root locus starts at the poles, follows the asymptotes, and moves towards the zeros.

Based on the steps above, the root locus can be represented as follows:

Starting at the poles ±√2, the branches move towards the zero at the origin.

The root locus approaches the imaginary axis along the asymptotes at Re(z) = √2.

As K increases from -∞ to -2, the root locus branches move towards the left on the real axis.

At K = -2, a breakaway occurs at Re(z) = -√2.

As K increases further from -2, the root locus branches move towards the left along the real axis.

Eventually, the root locus reaches the zero at the origin.

Explanation

Debby has 15 yards in total to make pillow cases.

Each pillow case requires (8/9) yard.

How much yard is left after she makes as many pillowcases as she can.

1 pillowcase = (8/9) yard

We need to obtain how many pillowcases 15 yards can make.

That is obtainable by dividing 15 by (8/9).

Hence, 16.875 pillowcases of (8/9) yards each, are obtainable from 15 yards.

Since pillowcases cannot exist in fraction, the 0.875 pillowcase has to be extra yards of fabric.

1 pillowcase = (8/9) yard

0.875 pillowcase = 0.875 × (8/9) = (7/8) × (8/9) = (7/9) or 0.778 yards.

Hence, the number of yards that will be left after making as many

Step-by-step explanation:

The probability that the reimbursement is greater than 3000 but less than 9000, given that the loss exceeds the deductible, is 0.2355.

We are given that the loss under a liability policy is modeled by an exponential distribution. This means that the amount of the loss that exceeds the deductible follows an exponential distribution.

The insurance company will cover the amount of the loss in excess of a deductible of 2000. So, we are interested in calculating probabilities related to the reimbursement amount (Y) given that the loss exceeds the deductible.

We are given that the probability that the reimbursement is less than 6000, given that the loss exceeds the deductible, is 0.50. Mathematically, this can be expressed as:

P(Y ≤ 6000 | X > 0) = 0.50

where X is the amount of the loss that exceeds the deductible.

Using the memoryless property of the exponential distribution, we can rewrite the probability as:

P(X ≤ 4000) = 0.50

This is because P(Y ≤ 6000 | X > 0) is equivalent to P(X ≤ 4000) since the deductible is 2000.

From the given probability, we can determine the parameter λ of the exponential distribution. We have:

P(X > 2000) = e^(-λ*2000) = 0.5

Solving for λ, we find:

λ = ln(0.5)/(-2000) ≈ 0.00034657

Now, we want to calculate the probability that the reimbursement is greater than 3000 but less than 9000, given that the loss exceeds the deductible:

P(3000 < Y ≤ 9000 | X > 0)

Using the memoryless property, we can rewrite this as:

P(X > 1000) - P(X > 7000)

Substituting the value of λ we found earlier, we have:

P(3000 < Y ≤ 9000 | X > 0) = e^(-λ1000) - e^(-λ7000)

Plugging in the value of λ, we can calculate the probability:

P(3000 < Y ≤ 9000 | X > 0) ≈ e^(-0.34657) - e^(-2.426) ≈ 0.3226 - 0.0871 ≈ 0.2355

Therefore, the probability that the reimbursement is greater than 3000 but less than 9000, given that the loss exceeds the deductible, is approximately 0.2355.

A = P(1+r/n)(nt), where P is the original principal, r is the annual interest rate, n is the number of times the interest is compounded annually, and t is the number of years the money has been held, is the formula for compound interest.

To calculate the final amount of money in the account:

 First, divide the 8% annual interest rate by 100 to get a decimal value: 0.08.

Find the number of times the interest is compounded annually. Since it is done quarterly, the answer is n = 4.

Put these values into the formula now, along with the $1200 principle sum and the number of years, 5, to complete it:

A = $1200(1+(0.08/4))^(4*5) = $2490.07

  to determine how long it will take for the initial sum to double to $2400.

 Divide the final sum by the starting sum: 2400/1200 = 2

 Take the natural logarithm of 2: ln(2) = 0.693

Decimalize the result and divide it by the interest rate: 0.693 / 0.08 = 8.66 years

 Therefore, the time it will take for the initial sum of money to double to $2400 is 8.66 years.

The difference between the two investments after 35yrs is $4700 and  Bank of America is offering higher interest than 5/3rd banks.

Most interest is compounded semiannually, quarterly, or monthly. Continuous compounding assumes that interest is compounded indefinitely and reentered on the balance sheet. The continuous compounding formula takes into account four variables.

For the given question,

5/3rd bank offers continuous interest:

For continuous interest, A = P\(e^{rt}\)

where,

P = the initial amount

A = the final amount

r = the rate of interest

t = time

e is a mathematical constant where e ≈ 2.7183.

A = 10000 × \(2.71^{0.042*35}\)

A =  10000 × 4.04

The sample size necessary for a 90% confidence interval about the mean height of a shrub with a margin of error of 0.5 inches and a population standard deviation of 1.3 inches is 18.

Margin of error is defined as the degree of the sampling errors in statistics. It can be calculated using the formula below.

MOE = z x (SD / √n)

where MOE = margin of error = 0.5 inches

z = found by using a z-score table

SD = sample standard deviation = 1.3 inches

n = sample size

At 90% confidence interval, the area in each tail of the standard normal curve is 5, and the cumulative area up to the second tail is 95.

(100 - 90) / 2 = 5

100 - 5 = 95

Find 0.95 in the z-table to get the value of z.

At p = 0.95, z = 1.647

Plug in the values to the formula and solve for the sample size, n.

MOE = z x (SD / √n)

0.5 = 1.647 x (1.3 / √n)

√n = 1.647(1.3) / 0.5

n = 18.34
