Answers

Answer 1

Rachel $8500 invested at 4% and $8800 invested at 2% interest rate.

Define the term Investment?

Investment is the act of allocating money or resources with the expectation of generating income or profit in the future.

Let x be the amount invested in the second account (with a 4% interest rate).

Then, since Rachel invested $300 more in the first account, the amount invested in the first account (with a 2% interest rate) is (x + 300)

We know that the total interest income Rachel earned was $516. We can set up an equation using the interest formula: (2% means 0.02 and 4% means 0.04)

⇒ 0.02(x + 300) + 0.04x = 516
⇒ 0.02x + 6 + 0.04x = 516
⇒ 0.06x + 6 = 516
⇒ 0.06x = 510
⇒ x = 8500

So, Rachel invested $8500 in the second account (with a 4% interest rate)

and (x + 300) = (8500 + 300) = $8800 in the first account (with a 2% interest rate).

Therefore, Rachel $8500 invested at 4% and $8800 invested at 2%.

One can of soda has a capacity of 355mL. How may liters of soda does 12.

Answers

12 cans of soda hold 4.26 liters of soda.

The process for determining the total volume of soda would be the same using the specific capacity and number of cans.

We need to determine how many milliliters of soda 12 cans hold. We can do this by multiplying the capacity of one can (355 mL) by the number of cans (12):

355 mL/can x 12 cans = 4,260 mL

Now we need to convert this amount to liters. We know that 1 liter is equal to 1,000 milliliters, so we can divide the total volume in milliliters by 1,000:

4,260 mL ÷ 1,000 mL/L = 4.26 L

Answers

The probability density function (pdf) of the lifetime of a certain device is expressed as: f (x) = 2λxe^−λx² ; x > 0; λ > 0

Mean: E(x) = -2λ + C

Mode: x = 0

Median: x = ±√(-ln(0.5)/λ)

Variance: Var(x) = 0

What is probability density function?

Probability density function (PDF) describes the relative likelihood for a random variable to take on a given value. It is a continuous function that is used to represent the probability distribution of a continuous random variable.

The probability density function (pdf) of the lifetime of a certain device is expressed as:

f (x) = 2λxe^−λx² ; x > 0; λ > 0

Mean: The mean (or expected value) of the probability density function is given by:

E(x) = ∫x.f(x)dx = ∫x.2λxe^−λx²dx

= -2λe^−λx² + C

E(x) = -2λ + C

Mode: The mode of the probability density function is the value at which the maximum density occurs. This occurs at the point where the derivative of the function is equal to 0.

f′(x) = 2λxe^−λx²

= 0

x = 0

Therefore, the mode of the probability density function is 0.

Median: The median is the value of the random variable for which the cumulative distribution function is equal to 0.5.

F(x) = 1 − e^−λx² = 0.5

1 − e^−λx² = 0

e^−λx² = 0.5

−λx² = ln(0.5)

x² = -ln(0.5)/λ

x = ±√(-ln(0.5)/λ)

Therefore, the median of the probability density function is given by:

x = ±√(-ln(0.5)/λ)

Variance: The variance of the probability density function is given by:

Var(x) = E(x²) - (E(x))²

E(x²) = ∫x².f(x)dx

= ∫x^2.2λxe^−λx²dx

= -2λe^−λx² + C

E(x²) = -2λ + C

Var(x) = -2λ + C - (-2λ + C)²

= 0

Therefore, the variance of the probability density function is 0.

It's illegal to bet on political races in the United States, but overseas betting on American elections is common. As of this writing, Hillary Clinton is the favorite to win the presidency in 2016, with odds listed as 8/11. Explain what that means, including relating it to probability.

Answers

Odds are a measure of the likelihood of an event occurring. In the case of betting on an event, odds represent the ratio of the payout for a winning bet to the amount of the bet. So, in this case, odds of 8/11 mean that if you were to bet $11 on Hillary Clinton winning the presidency and she did win, you would get a payout of $8, plus your original $11 bet.

To relate this to probability, you would calculate the implied probability of the odds. This is a simple calculation:

Implied probability = (1 / (odds + 1)) x 100%

Using the odds of 8/11 for Hillary Clinton, the implied probability would be:

(1 / (8/11 + 1)) x 100% = 57.89%

So, according to these odds, there is a 57.89% chance that Hillary Clinton will win the presidency.

Answer:

57.89%

Step-by-step explanation:

Implied probability = (1 / (odds + 1)) x 100%

Using the odds of 8/11 for Hillary Clinton:

Implied probability = (1 / (8/11 + 1)) x 100% = 57.89%

There is a 57.89% chance that Hillary Clinton will win the presidency.

What is circumference of circle?

The circumference of a circle is the distance around the edge or boundary of the circle. It is a fundamental geometric property of a circle and is defined as the product of the circle's diameter and pi (π), which is a mathematical constant approximately equal to 3.14.

The formula to calculate the circumference of a circle is C = 2πr or C = πd

where C represents the circumference, r represents the radius, and d represents the diameter of the circle,

1. Diameter = 30 cm

Circumference = π x Diameter

= 22/7 x 30

= 94.29 cm

2. Diameter = 15 m

Circumference = π x Diameter

= 22/7 x 15 x 100

= 471.43 m

3. Diameter = 40 ft

Circumference = π x Diameter

= 22/7 x 40 x 12

= 377.14 ft

4. Diameter = 20 cm

Circumference = π x Diameter

= 22/7 x 20

= 62.86 cm

5. Diameter = 8 m

Circumference = π x Diameter

= 22/7 x 8 x 100

= 251.43 m

6. Diameter = 12 cm

Circumference = π x Diameter

= 22/7 x 12

= 37.71 cm

7. Diameter = 22 in

Circumference = π x Diameter

= 22/7 x 22

= 69.71 in

8. Diameter = 34 m

Circumference = π x Diameter

= 22/7 x 34 x 100

= 1068.57 m

9. Diameter = 10 m

Circumference = π x Diameter

= 22/7 x 10 x 100

= 314.29 m

10. Diameter = 34 cm

Circumference = π x Diameter

= 22/7 x 34

= 106.86 cm

Therefore, the circumference of the given diameters are 94.29 cm, 471.43 m, 377.14 ft, 62.86 cm, 251.43 m, 37.71 cm, 69.71 in, 1068.57 m, 314.29 m, 106.86 cm.

b. Compounded quarterly: $19,338.56

c. Compounded monthly: $19,416.32

d. Compounded continuously: $19,451.08

Step-by-step explanation:

The formula for the accumulated value (A) of an investment with an initial principal (P), an interest rate (r) and a compounding period (n) for a number of years (t) is:

A = P(1 + r/n)^(n*t)

Using this formula, we can calculate the accumulated value for each of the compounding periods given:

a. Compounded semiannually:

A = $15,000(1 + 0.065/2)^(2*5) = $19,216.67

b. Compounded quarterly:

A = $15,000(1 + 0.065/4)^(4*5) = $19,338.56

c. Compounded monthly:

A = $15,000(1 + 0.065/12)^(12*5) = $19,416.32

d. Compounded continuously:

A = $15,000e^(0.0655) = $19,451.08

Therefore, the accumulated value of the investment varies depending on the compounding period, with more frequent compounding resulting in a higher accumulated value.

What is cyclic group?

In group theory, a cyclic group is a group that can be generated by a single element. That is, it is a group that is generated by a single element a, where any element of the group can be expressed as a power of a.

The order of a cyclic group is equal to the order of its generator. If the generator has order n, then the cyclic group has n elements. The group operation in a cyclic group can be either additive or multiplicative, depending on the notation used.

The statement defines a cyclic subgroup is a subgroup of a group that is generated by a single element. The element used to generate the subgroup is called the generator of the cyclic subgroup. The set of all powers of the generator, including the inverse powers and the identity element, forms the cyclic subgroup.

In other words, the cyclic subgroup generated by an element a of a group is the smallest subgroup that contains a. It consists of all possible combinations of a and its inverse under the group operation.

A group or subgroup is called cyclic when it can be generated by a single element. In other words, if every element of the group can be expressed as a power of a single element, then the group is cyclic.

Which of the following equations represents a line that is perpendicular to the line that passes through the points below?
(-3,10) (3,8)

Answers

The equation of the line that is perpendicular to the line passing through the points (-3, 10) and (3, 8) is y = 3x + 9.

To find a line that is perpendicular to another line, we need to use the fact that the slopes of the two lines are negative reciprocals of each other.

The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the slope formula:

slope = (y₂ - y₁)/(x₂ - x₁)

Therefore, the slope of the line passing through the points (-3, 10) and (3, 8) can be found as follows:

slope = (8 - 10)/(3 - (-3)) = -1/3

Now, to find the equation of a line perpendicular to this line, we need to find the negative reciprocal of the slope -1/3, which is 3.

Therefore, the slope of the line perpendicular to the given line is 3.

Now, we can use the point-slope form of a linear equation to find the equation of the perpendicular line. The point-slope form of a linear equation is:

y - y₁ = m(x - x₁)

where m is the slope of the line, and (x₁, y₁) is any point on the line.

We know the slope of the perpendicular line is 3, and we can choose any point on the line. Let's choose the midpoint of the given points (-3, 10) and (3, 8), which is

=> ((-3+3)/2, (10+8)/2) = (0, 9).

So, using the point-slope form of the equation with m = 3 and (x1, y1) = (0, 9), we get:

y - 9 = 3(x - 0)

Simplifying this equation, we get:

y = 3x + 9

Now Q gave some money to P and R such that the amounts with them were doubled. Finally R also gave some money with him to P and Q such that the amounts with them were doubled. At this stage, each of them had 240.What was the initial amount with P?

Answers

The initial amount of money with P was 2Q0 = 2 * 3Q0 = 6Q0.

What is amount?

Amount is the sum of money or quantity of something. It is usually measured in numerical values such as dollars, pounds, or euros. It is used to describe the total of something, such as how much money is in a bank account or the total cost of a purchase. Amount can also be used to describe a quantity of something such as the amount of time spent on a project or the amount of people present at an event.

Let us denote the initial amount of money with P, Q and R as P0, Q0 and R0 respectively. We know that P gave some money to Q and R such that their amounts were doubled, which implies that P0 = 2(Q0 + R0). Similarly, Q gave some money to P and R such that their amounts were doubled, which implies that Q0 = 2(P0 + R0). Finally, R gave some money to P and Q such that their amounts were doubled, which implies that R0 = 2(P0 + Q0). Substituting the value of P0 from the first equation in the third equation, we get:

2(Q0 + R0) = 2(P0 + Q0)
2Q0 + 2R0 = 2P0 + 2Q0
R0 = P0

Substituting the value of R0 in the first equation, we get:

P0 = 2(Q0 + R0)
P0 = 2(Q0 + P0)
P0 = 2Q0 + P0
P0 = 2Q0

Finally, substituting the value of P0 in the second equation, we get:

Q0 = 2(P0 + R0)
Q0 = 2(2Q0 + R0)
Q0 = 4Q0 + R0

is 400% of 2 less than 10, greater than 10 but less than 100, or greater than 100?

Answers

Answer:

400% of 2 is 8, so it would be less than 10

Step-by-step explanation:

To find out if 400% of 2 is less than 10, greater than 10 but less than 100, or greater than 100, we need to calculate 400% of 2, which is:

(400/100) x 2 = 8

So, we know that 400% of 2 is 8.

Since 8 is less than 10, we can say that 400% of 2 is less than 10.

Solve the right triangle using the information given. Round answers to two decimal places, if necessary. a = 4, b = 6; Find c, α, and β.

Answers

Step-by-step explanation:

first, remember Pythagoras :

c² = a² + b²

c is the Hypotenuse (the side opposite of the 90° angle).

a and b are the legs.

so, in our case

c² = 4² + 6² = 16 + 36 = 52

c = sqrt(52) = 7.211102551... ≈ 7.21

and then remember the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

a, b, c are the sides, A, B, C are the corresponding opposite angles (here also called alpha, beta. gamma would be the 90° angle).

so,

4/sin(alpha) = c/sin(90) = c

4 = c×sin(alpha)

sin(alpha) = 4/c = 4/7.211102551... = 0.554700196...

alpha = 33.69006753...° ≈ 33.69°

we don't need to do that much calculation for the third angle beta, as we know the sum of all angles in a triangle is always 180°.

so,

180 = alpha + beta + 90 = 33.69 + beta + 90

90 = 33.69 + beta

56.30993247... = beta ≈ 56.31°

Which is the graph of the system of linear equations?

Here we have the following system of equations:

y = -(1/3)x + 1

y = -2x - 3

To graph the system of equations, we just need to graph both of these lines in the same coordinate axis. The point where the lines intercept are the solutions of the system.

In the image at the end we can see the graph of the system of equations, there we also can see that the solution is the point (-2.4, 1.8)

different equation dy÷dx+ytanx=secx​

Answers

Answer:

First, we rearrange the equation to isolate the y-term on one side:

dy/dx + ytanx = secx

Then, we multiply both sides by the integrating factor, which is e^(∫tanx dx) = e^(ln|secx|) = |secx|: | secx| dy/dx + ysecx tanx = 1

Next, we can write this as the derivative of a product using the product rule: d/dx (y |secx|) = 1

Integrating both sides with respect to x, we get:  y |secx| = x + C

where C is the constant of integration. Solving for y, we have:

y = (x + C)/|secx|

Note that there is a singularity at x = (2n + 1)π/2, where the denominator |secx| is zero. At these points, the solution is not defined

If a = 3 and b = -2, what is the value of a2 + 3ab ”“ b2?​

Answers

Substituting a = 3 and b = -2 into the expression a^2 + 3ab - b^2, we get:

a^2 + 3ab - b^2 = 3^2 + 3(3)(-2) - (-2)^2

a^2 + 3ab - b^2 = 9 - 18 - 4

a^2 + 3ab - b^2 = -13

Therefore, the value of a^2 + 3ab - b^2 when a = 3 and b = -2 is -13.
