A. 1.026%
B. 102.6%
C. 10.26%
D. 0.10%

Answers

Answer 1

The effective rate of the $8,000 note is (d) 0.10%

How to determine the effective rate

From the question, we have the following parameters that can be used in our computation:

Principal, P = $8,000

Discount rate, r = 10%

Number of days, d = 90

The effective rate can be calculated using the following formula

Effective rate = (1 + (nominal rate ÷ number of compounding periods)) ^ (number of compounding periods) - 1

This can be expressed as

Effective rate = (1 + r/n)^n - 1

Substitute the known values in the above equation, so, we have the following representation

Effective rate = (1 + (10%/90))^(90) - 1

Evaluate

Effective rate = 0.10%

Hence, the effective rate is (d) 0.10%

Answers

The expected value of X + 1 (Y - 1) can be calculated using the formula E(X + 1)(Y - 1) = E(X)E(Y) + E(X) - E(Y) + 1. Thus, the expected value of X + 1 (Y - 1) = 9/2 * 9/2 + 9/2 - 9/2 + 1 = 17. Therefore, the correct answer is d) 17.

The expected value of X + 1 (Y - 1) is a measure of the average value of the product of two independent random variables, X and Y. To calculate this expected value, we can use the formula E(X + 1)(Y - 1) = E(X)E(Y) + E(X) - E(Y) + 1. Since X and Y are independent random variables, we know that E(X) = E(Y) = 9/2. Plugging this value into the formula, we get E(X + 1)(Y - 1) = 9/2 * 9/2 + 9/2 - 9/2 + 1 = 17. This is the expected value of X + 1 (Y - 1). Therefore, the correct answer is d) 17.

Consider n independent flips of a coin having probability p of landing on heads. Say that a changeover occurs whenever an outcome differs from the one preceding it. For instance, if n=5 and the outcome is HHTHT, then there are 3 changeovers. Find the expected number of changeovers. Hint: Express the number of changeovers as the sum of n-1 Bernoulli random variables.

Answers

The expected number of transitions is 22p(1-p) when take into account n separate coin flips with a p percent chance of landing on heads.

Given that,

Take into account n separate coin flips with a p percent chance of landing on heads. Say a changeover happens any time an outcome diverges from the one that came before it. For instance, there are 3 changeovers if n=5 and the result is HHTHT.

We have to determine the anticipated number of transitions.

We know that,

Independent flips,

n =12

Probability of heads =p

Probability of tails =(1-p)

Let m=1,2,...n

If mth term may be head then (m+1)th outcome could be head or vice-versa.

Probability of change overs from mth to (m+1)th outcome =2p(1-p)

So, the  expected changeovers is given by

E[change overs] = (n-1) *2p(1-p)

= (12-1) × 2p(1-p)

=11 × 2p(1-p)

=22p(1-p)

Therefore, the expected number of transitions is 22p(1-p) when take into account n separate coin flips with a p percent chance of landing on heads.

Answers

For measurements of the same quantity, there won't be a significant difference in the standard deviation.

The standard deviation for Tests A and B is almost the same.

Total quantity in test a = n1 = 100

Total quantity in test b = n2=400

We know that the standard error is defined as: [tex]S E=\frac{\sigma}{\sqrt{n}}[/tex]

where we have, for test A [tex]$$S E_A=\frac{\sigma}{\sqrt{100}}$$[/tex]

and for Test B [tex]$$S E_B=\frac{\sigma}{\sqrt{400}}=\frac{1}{2} * \frac{\sigma}{\sqrt{100}}$$[/tex]

Solve for z in the system of equations.

x + y - z = -5

2x - y + z = 8

x - 4y + 3z = 5

Answers

Answer:

z = 20

Step-by-step explanation:

Elimination Method:

We can use the elimination method in a systems of 3 equations, just as we did when we were solving systems of 2 equations. While the method we apply it is the same, we have to apply it multiple times as elimination gets rid of one variable (usually) and since we're dealing with 3 variables, that still leaves us with 2 variables and we need to cancel once more.

Applying Elimination Method:

We want to develop two linear equations, by applying elimination twice to each equation at least once, and then from there we can apply elimination once more.

Since we're solving for "z", we don't want to immediately cancel it out. So let's use the following two equations:
[tex]x+y-z=-5\\\\x-4y+3z[/tex]

Let's cancel out the "x", by manipulating one equation to be -x. We can do this by multiplying one equation by -1, but remember we have to apply this to both sides of the equation. Let's do it to the top one (you could also do it to the bottom one)

[tex]-1(x+y-z)=-(-5)\implies -x-y+z=5[/tex]

So now let's add the two equations:

[tex]\ \ \ (-x-\ y+\ z)=5\\+(\ \ x-4y + 3z) = 5\\ ------------\\ -5y+4z=10[/tex]

Now let's apply the same thing, but to the middle and bottom equation. Since they don't have the same absolute value coefficients (ignoring the sign) we need to multiple one by a value other than just negative one. So let's multiply the bottom equation by -2 so that the bottom will have a -2x which will cancel when adding it to 2x

[tex]-2(x - 4y + 3z) = -2(5)\\-2x + 8y - 6z = -10[/tex]

Now let's add the equations:

[tex]\ \ \ (\ \ 2x-y+z)=8\\+(-2x + 8y - 6z)=-10\\\\-----------\\7y - 5z = -2[/tex]

So now we have the two equations:

[tex]7y-5z=-2\\-5y+4z=10[/tex]

From here we can apply any method we want, from here I'll use substitution. Since we want to get rid of the "y", let's solve for "y" in terms of z, so once we substitute we have no "y" terms left.

[tex]7y-5z=-2\\7y=5z-2\\y=\frac{5z-2}{7}[/tex]

Now let's plug this into the second two-variable equation we made.

[tex]-5(\frac{5x-2}{7})+4z=10\\\\\frac{-25x+10}{7}+4z=10\\\\\frac{-25}{7}z+\frac{10}{7} + \frac{28}{7}z = \frac{70}{7}\\\\\frac{-25+28}{7}z = \frac{70-10}{7}\\\\\frac{3}{7}z = \frac{60}{7}\\\\z = \frac{60}{7} * \frac{7}{3}\\\\z = 20[/tex]

use the formulas for lowering powers to rewrite the expression in terms of the first power of cosine, as in example 4. cos4(x) sin2(x)

Answers

The expression in terms of first power of cosine cos4x*sin2x = 1/16 + cos(2x)/16 - cos(4x)/16 - cos(4x)cos(2x)/16.

How to lower the power of expression in trigonometry?

The cosecant and cotangent functions, which exist in the numerator and denominator, can be used to simplify a trigonometric statement by writing it in terms of the sine and cosine functions.

sin2x+cos2x = 1 and cos2x = (1+cos(2x))/2

Using the first identity, we have sin2x = 1-cos2x.

So we have that cos4x*sin2x = cos4x(1-cos2x)

Expanding, we have cos4x-cos6x.

Since cos2x=  (1+cos(2x))/2, this implies cos4x = ((1+cos(2x))/2)² and cos6x=((1+cos(2x))/2)³.

Expanding each one, we have

cos4x - cos6x = 1/4(1+2cos(2x) + cos2(2x)) - 1/8(1+3cos(2x) + 3cos2(2x) + cos3(2x)).

Simplifying we get

cos4x - cos6x = 1/8 + 1/8(cos(2x) - cos2(2x) - cos3(2x)).

cos2(2x) = 1/2(1+cos(4x)) and cos3(2x)

= cos2(2x)*cos(2x)

= 1/2(1+cos(4x)) * cos(2x)

= 1/2(cos(2x) + cos(4x)*cos(2x))

Substituting, we get

cos4x - cos6x = 1/8 + 1/8(cos(2x) - 1/2(1+cos(4x)) - 1/2(cos(2x) + cos(4x)*cos(2x)))

Cleaning it up, we get

cos4x*sin2x = 1/16 + cos(2x)/16 - cos(4x)/16 - cos(4x)cos(2x)/16.

Hence, The expression in terms of first power of cosine cos4x*sin2x = 1/16 + cos(2x)/16 - cos(4x)/16 - cos(4x)cos(2x)/16.

To find angle 1 we know that the other angles in the smaller triangle are 60 degrees and 90 degrees therefore we would add them up to being 150

60+90=150
180-150=30=m<1

We would then subtract it from 180 to get the measurement of angle 1 which is 30 degrees

We could do the same to find angle 2
90+30=120
180-120=60=m<2
Interior angles in triangles always add up to 180

Angle 1 = 180 - 90 - 60 = 30
(90 because there is a right triangle unlabeled)

If angle 1 is 30 and angle 1 and 2 are a right triangle combined (90°), then:

Angle 2 = 90 - 30 = 60

Have a nice day ^^ (again)

Angle 2 = 180 -

Solve the problem by finding x. I don’t know how to? Do you.

Answers

Answer:

x =  e^3   +7

Step-by-step explanation:

ln ( x-7) = 3

To solve for x, raise each side to base e

e ^ ( ln ( x-7) ^= e^3

x-7 = e^3

Add 7 to each side

x-7+7 = e^3   +7

x =  e^3   +7

43. Ford Davis borrowed $14,000 of a non-interest-bearing, simple discount, 8% , 90-day note. Assume ordinary interest. What are Ford's proceeds?
A. $14,000
B. $13,720
C. $13,000
D. $17,320

Answers

Answer: B. $13,720

Step-by-step explanation: To calculate Ford's proceeds, we need to first find the discount, which is equal to the interest on the loan multiplied by the principal amount of the loan. The interest is 8% of $14,000, or $1,120. The discount is then $1,120 * 90/360, or $310. The proceeds are equal to the principal amount minus the discount, or $14,000 - $310 = $13,720.

Suppose you want to purchase a $ 195000 house. If you put 20% down and finance the rest in a 15 year mortgage at an interest rate of 4%, what will your monthly payments be?
Monthly payment

Answers

The monthly payment on a principal of $156000 with interest rate of 4% over a time period of 15 years is $1153.91

Monthly Payment

The monthly payment is the amount paid per month to pay off the loan in the time period of the loan. When a loan is taken out it isn't only the principal amount, or the original amount loaned out, that needs to be repaid, but also the interest that accumulates.

The formula of monthly payment is given as;

A = P [r(1 + r)ⁿ] / [(1 + r)ⁿ - 1]

A =  Monthly paymentr = ratep = principaln = number of payment

The principal of the loan can be calculated as 20 % of 195000

20 / 100 = x / 195000

0.2 = x / 195000

x = 39000

The principal is 195000 - 39000 = 156000

The principal is 156000, rate is 4% and time is 15 year

Substituting the values into the formula

A = 156000[0.04(1 + 0.04)¹⁸⁰] / [(1 + 0.06)¹⁸⁰ - 1]

A = 1153.91

The monthly payment is $ 1,153.91

Which of the following are true? 1. If velocity is constant and positive, then distance traveled during a time interval is the velocity multiplied by the length of the interval. 2. If velocity is positive but decreasing, using the velocity at the beginning of each subinterval in a rectangle sum gives an overestimate of the distance traveled. Select one:a. Both 1 and 2 b. Just 1 c. Neither 1 or 2 d. Just 2

Answers

According to the statement given, Distance = Velocity X time = V1 X (t2 - t1), but this is the overestimate value

What is velocity?

Velocity is the rate at which a moving object's location changes as observed from a specific frame of reference and measured at a specific time standard.

1. Distance = velocity X time

= V X (t2 - t2)

2. According to the statement given,

Distance = Velocity X time

= V1 X (t2 - t1)

but this is the overestimate value, because

Distance = Area under velocity - time curve

therefore, statement 2 is correct

The surface area of the figure given which is a rectangular prism is 1362cm²

Surface Area of Rectangular Prism

The total region or area covered by all the faces of a rectangular prism is defined as the surface area of a rectangular prism. A rectangular prism is a three-dimensional shape. It has six faces, and all the faces are rectangular-shaped. Therefore, both the bases of a rectangular prism must also be rectangles.

The surface area of the prism is calculated by the formula

A = 2[(lw) + (lh) + (wh)]

A = Surface areal = length of the prismh = height of prismw = width of prism

To solve this problem, we have to divide the prism into two different parts and solve for the area.

For the first rectangular prism;

h = 14cmw = 14cml = 8cm

A = 2[(lw) + (lh) + (wh)]

A = 2[(8 * 14) + (8 * 14) + (14 * 14)]

A = 840cm²

The area of the second figure will be;

l = 8cmh = 17cmw = 5cm

A = 2[(8 * 17) + (17 * 5) + (8 * 5)]

A = 552cm²

The total surface area of the figure is 840cm² + 552cm² = 1362cm²
