Twelve friends share 4 cookies equally. What fraction of a cookie does each friend get? Write in simpliest form

So the probability that Angela gets to go to the meeting is 2/5.

Probability is a measure of the likelihood or chance of an event occurring. It is a numerical value between 0 and 1, where 0 means that the event is impossible and 1 means that the event is certain. Probability can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. It is an important concept in many fields, including mathematics, statistics, physics, and engineering, and is used to make predictions, analyze data, and make decisions under uncertainty.

Here,

There are a total of 5 people in the club, so there are 10 possible pairs of people that could be chosen to go to the meeting. Since each pair is equally likely to be chosen, the probability of any particular pair being chosen is 1/10.

To determine the probability that Angela gets to go to the meeting, we need to count the number of pairs that include Angela. There are 4 other people in the club, so there are 4 possible pairs that include Angela. Therefore, the probability that Angela gets to go to the meeting is:

P(Angela) = number of pairs that include Angela / total number of pairs

= 4 / 10

= 2 / 5

The probability of winning second prize in a 5/45 lottery is 1 in 8,145. This is calculated by taking the total number of possible combinations (8,145) and dividing it by the total number of possible outcomes (1).

The average rate of change representing the state whose temperature is decreasing slower is given as follows:

-1.5ºF/day.

The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.

For Maine, in 9 days, the temperature fell by 13.5ºF, hence the rate is given as follows:

-13.5/9 = -1.5ºF/day.

For Connecticut, in 2.5 days, the temperature fell by 6.25ºF, hence the rate is given as follows:

-6.25/2.5 = -2.25 ºF/day.

A slower decline is in Maine, as it has a lower rate of change.

The range of function is values on the y-axis: R=[-7,2].

A function is a mathematical concept that describes the relationship between two sets of numbers. It is a rule that assigns to each input (or element in the domain) exactly one output (or element in the range). In simpler terms, a function is like a machine that takes in a number and produces another number as output, according to some specific rules. The input is usually denoted by x, and the output by f(x), which is read as "f of x". Functions can take many forms, such as linear, quadratic, trigonometric, exponential, logarithmic, and more. They are widely used in mathematics, science, engineering, and many other fields to model and analyze various phenomena.

Here,

To find the range of a function, you need to determine all possible output values of the function. Start by identifying the function's domain, which is the set of all possible input values of the function. Once you know the domain, apply the function to each input value in the domain and record the corresponding output values. Once you have a list of output values, identify the smallest and largest values in the list. These values represent the range of the function. For example, consider the function f(x) = 2x + 1. The domain of this function is all real numbers.

To find the range, apply the function to several input values in the domain:

f(-3) = -5

f(-2) = -3

f(-1) = -1

f(0) = 1

f(1) = 3

f(2) = 5

f(3) = 7

These output values give us a set of possible output values, which are {-5, -3, -1, 1, 3, 5, 7}. The smallest value in the set is -5 and the largest value is 7, so the range of the function is [-5, 7].

Note that for some functions, it may be difficult or impossible to find the exact range. In such cases, you can use techniques such as graphing or calculus to estimate the range.

The amount and the compound interest on a sum of Rs. 62500 are Rs. 65625 and Rs. 3125, respectively.

Given:

Principal amount (P) = Rs. 62500

Rate of interest (R) = 5%

Time period (t) = 1 year

Interest is compounded yearly.

Formula for calculating compound interest is given as:

A = P(1 + R/100)ᵗ

where A is the amount.

Using this formula, we can find the amount (A) after one year:

A = 62500(1 + 5/100)¹

A = 65625

Therefore, the amount after one year is Rs. 65625.

To find the compound interest, we can subtract the principal from the amount:

Compound Interest = A - P

= 65625 - 62500

= 3125

Therefore, the compound interest is Rs. 3125.

Answer:

Step-by-step explanation:

Your sister can use the formula for calculating the present value of an annuity to determine how much she can withdraw each year.

The formula for the present value of an annuity is:

PV = Payment x (1 - (1 + r)^-n) / r

Where:

- PV is the present value of the annuity

- Payment is the amount of each withdrawal

- r is the annual interest rate

- n is the number of periods (in this case, 25 years)

We can rearrange this formula to solve for Payment:

Payment = PV x r / (1 - (1 + r)^-n)

We know that your sister has R375 000 to start with, and she wants to end up with zero in 25 years. So, her present value (PV) is R375 000, and we can assume her future value (FV) is zero.

Using the future value formula, we can calculate the interest rate she needs to earn in order to end up with zero in 25 years:

FV = PV x (1 + r)^n

0 = 375000 x (1 + r)^25

(1 + r)^25 = 1

1 + r = (1)^1/25

r = 0

This means that your sister needs to withdraw all of her money over the 25 years in order to end up with zero at the end.

Her withdrawal each year would be:

Payment = PV x r / (1 - (1 + r)^-n)

Payment = 375000 x 0.08 / (1 - (1 + 0.08)^-25)

Payment = R34,028.82 per year

Your sister can withdraw R34,028.82 at the beginning of each year for the next 25 years, and she will end up with zero at the end, assuming she earns an 8% return on her invested funds.

The series [tex]\tan(2^{-n})[/tex] is convergent.

In mathematics, the cοnvergence οf a series refers tο the behaviοr οf the series' partial sums as mοre terms are added. A series cοnverges if its sequence οf partial sums apprοaches a finite limit, which is called the sum οf the series. If the sequence οf partial sums dοes nοt apprοach a finite limit, the series diverges.

The series [tex]\tan(2^{-n})[/tex] converges because of the following reasons:

As n increases, [tex]2^{-n}[/tex] becomes very small, which makes [tex]\tan(2^{-n})[/tex] close to its linear approximation. Therefore, we can use the linear approximation of [tex]\tan(2^{-n})[/tex] to estimate its value.

The linear approximation of [tex]\tan(2^{-n})[/tex] is [tex]2^{-n}[/tex], which means that [tex]\tan(2^{-n})[/tex] ≈ [tex]2^{-n}[/tex] when [tex]2^{-n}[/tex] is small.

Since the series [tex]2^{-n}[/tex] is convergent, by comparison test, the series [tex]\tan(2^{-n})[/tex] is also convergent.

Alternatively, we can also use the fact that the series tan(x) is convergent for x ∈ (0, π/2), and since [tex]2^{-n}[/tex] → 0 as n → ∞, we have [tex]\tan(2^{-n})[/tex] → tan(0) = 0, which implies that the series [tex]\tan(2^{-n})[/tex] is convergent.

Answer:

Step-by-step explanation:

First, we need to calculate the company's credit sales for the year:

Credit Sales = Receivables / (Days Sales Outstanding / 360)

Credit Sales = R180,000 / (60/360) = R1,080,000

Next, we need to calculate the company's net income:

Net Income = Profit Margin x Credit Sales

Net Income = 0.08 x R1,080,000 = R86,400

We can calculate the company's total equity as follows:

Total Equity = Total Assets x (1 - Debt Ratio)

Total Equity = R4,000,000 x (1 - 0.75) = R1,000,000

Finally, we can calculate the ROE:

ROE = Net Income / Total Equity

ROE = R86,400 / R1,000,000 = 0.0864 or 8.64%

Therefore, Third Rock Ventures' return on equity is 8.64%.

Based on the employee contribution, the Traditional IRA is the better choice because the employee will be taxed at a lower rate on lower earnings in retirement than during employment. The Option A is correct.

The Traditional IRA allows the employee to make contributions on a pre-tax basis, which reduces the taxable income during the years of contribution. This reduces the tax liability during employment years in the 33% tax bracket. During retirement, the employee will be in the 15% tax bracket, which means they will pay a lower tax rate on the withdrawals from the Traditional IRA.

In contrast, the Roth IRA contributions are made with after-tax dollars, and the withdrawals during retirement are tax-free. Since the employee is currently in the 33% tax bracket, they will pay a higher tax rate on their current income than they would in retirement. Therefore, the Traditional IRA is a better choice for the employee in this scenario.

Step-by-step explanation:

It should be noted that to use the diagram to figure out how many 2/5-ounce doses Zoe has, she can divide the 7/3-ounce amount into equal parts of 2/5 ounce.

One way to do this is to divide 2/5 by 1/5 to get the number of 1/5-ounce portions that make up a 2/5-ounce dose, which is 2. Then, divide 7/3 by 2/5 to get the total number of 2/5-ounce doses she has.

So, using the diagram, Zoe can count the number of 1/5-ounce portions she has, and then divide that number by 2 to find out how many 2/5-ounce doses she has.

Alternatively, Zoe could redraw the diagram to show 2/5-ounce portions instead of 1/5-ounce portions, and then count the number of 2/5-ounce portions she has. She would need to divide the original diagram into equal parts of 2/5 ounce by drawing lines to divide each square into two parts. Then she can count the number of squares that represent a 2/5-ounce dose.

Let X be the number οf machines that need cοrrecting adjustments during a day's prοductiοn run, and let p = 0.2 be the prοbability that any οne machine needs cοrrecting.

Then, X fοllοws a binοmial distributiοn with parameters n = 6 (the number οf machines) and p = 0.2 (the prοbability οf a machine needing cοrrecting).

The prοbability οf X is:

P(X > 2) = 1 - P(X <= 2)

Tο calculate P(X <= 2), we can sum the prοbabilities οf X taking οn the values 0, 1, and 2:

P(X <= 2) = P(X = 0) + P(X = 1) + P(X = 2)

P(X = 0) = (6 chοοse 0) * 0.2⁰ * 0.8⁶ = 0.2621

P(X = 2) = (6 chοοse 2) * 0.2²* 0.8⁴ = 0.2621

Therefοre,

P(X <= 2)
