They must invest $269.54 billion quarterly at 4% compound interest.

How can it determine how much it needs to invest now to reach $1,600 billion in twelve years?

We use the compound interest formula to figure out how much the International Monetary Fund needs to raise over the next 12 years in order to lend to developing nations at 4% interest compounded quarterly.

Interest that is calculated based on the initial principal as well as all of the interest that has accumulated over previous periods is referred to as compound interest. The power of compound interest is the process of producing "interest on interest. "Any frequency schedule, from continuous to daily to annual, can be used to compound interest.

What is the formula for compound interest?

Given that A = amount raised = $1600 billion, r = compound interest rate = 4% quarterly = 4%  1/4 year = 4%  4 = 16% = 0.16 per year, and n = number of years = 12, we have P = A/(1 + r)n. Substituting the values of the variables into the equation, we have P = $1600 billion/(1 + 0.16)12 P = $1600 billion/(1.16)12 P = $1600 billion/5.93

Convenience sampling is the least likely to produce a representative sample of the students.

Using the convenience sampling technique, individuals are chosen based on their accessibility and availability. This kind of sampling is frequently employed in studies when the objective is to swiftly collect data from a sample group rather than to acquire a representative sample of the population. If a person is willing to engage in the study  to the researcher, they are chosen for convenience sampling. The primary advantage of this strategy is that it is very simple and quick to apply; however, the primary downside is that the sample may not be representative of the population.

Answer:

No solution

Step-by-step explanation:

We can easily tell that there are no solutions by using the discriminant rule.

The discriminant rule comes directly from the discriminant of the quadratic equation and is b^2-4ac

It can tell us three things about the solution:

When the discriminant is less than 0, there is no solution.

When the discriminant equals 0, there is one distinct solution.

When the discriminant is greater than 0, there are two distinct solutions

In the problem a = 1, b = 6, c = 10.

Plugging in what we have gives us 6^2*4(1)(10) = -4.

-4<0 so there are no real solutions.

For the given condition bad check submission and check verification system from a random sample of checks , the probability value is

0.0618 > 0.01 which proves that it does not provide sufficient evidence of the effective check verification system.

As given in the question,

Given 5% of all the submitted checks were bad.

Null hypothesis H₀ : p = 0.05

For effective check verification system

Hₐ : p < 0.05

Statistic test :

z = ( x - μ ) / (σ /√n)

Here , x = 45 / 1124

             = 0.04

Data collected from the random sample are:

μ = 0.05

σ = √ 0.05 × 0.95

n = 1124

Substitute all the values in the formula we get,

z = ( 0.04 - 0.05 ) / ( √ 0.05 × 0.95 / √1124 )

  = - 0.01 / 0.0065

  = - 1.54

Probability for z = - 1.54 is equal to 0.0618 ( from table )

Now 0.0618 > 0.01

Sufficient evidence does not exist for the check verification system.

Therefore,  the probability value is 0.0618 > 0.01  which proves that it does not provide sufficient evidence of the effective check verification system from a random sample of checks.

Step-by-step explanation:

The number at the end (-6) is your Y intercept. You can find this by looking at the number that the blue line touches on the up and down graph line.

The middle number in your equation is the slope. You can find this by looking for two points where your blue line crosses the corner of the little boxes. Then you count how many boxes it takes to get from one point to another. Your slope is negative (because the left side is higher than the right) once you count between your points, put the rise number (up and down) over the run number (left to right).

A scalene triangle exists with the side lengths 12,15 and 18 feet.

The three sides of the triangle are 12 feet , 15 feet and 18 feet.

Now we know from the properties of triangle that if the sum of the smaller sides is greater than the largest side , then it is a triangle.

Here we can see that the triangle is formed by the given sides.

Now, 12 +15 = 27 > 18 hence the triangle is possible.

Since all the sides are of different lengths the triangle is scalene.

Scalene refers to any triangle with three unequal sides. Because there are three different sides, there must also be three different sizes of angles. This triangle is one of the three varieties that can be distinguished by the traits of its sides.

A scalene triangle is a triangle with variable lengths for each of its three sides and three angles. The different measures have no impact on the total interior angle of the scalene triangle.

The joint probability mass function  of x,y is 0.1458  if x is number of tails in three flips of coins and y is the outcome of six-faced die.

We know very well that probability is defined as the ratio of number of favorable outcomes to the total number of outcomes.

Here, coin is tossed three times means that 2³=8 different possible outcomes possible.

The total combination of tail appearing in 3 times flipping are {TTT,TTH,THT,HTT,HTH,HHT,THH}

So, total 7 combinations are possible for a tail appearing on flipping coin three times.

So, probability of tail appearing in three flips=7/8

Therefore, value of x=7/8

Now, we know that a dice has six faces and for each face there is equal probability to come at the top face and that probability value is 1/6

So, joint probability of mass function of x,y = (probability of tail appearing in three flips × probability of outcomes of a six-sided dice)

=>P(x,y)=(7/8)×(1/6)

=>P(x,y) = 7/48

What is Function?

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input.

If each input value has one and only one output value, then a relation is by definition a function.

A function must have both an independent and at least one dependent variable. For instance, assuming a function:

"Y" stands for the dependent variable, and "x" stands for the independent variable.

The set of potential input values is known as the function's domain, while the set of potential output values is known as the range.

The slope of vertical lines is unknown. A vertical line is not an illustration of a functional connection because "x" is constant.

For horizontal lines, any x-value results in the same y-value. They are referred to as "Constant functions."

b) lim 0:2 = 0.5 is absolutely convergent. The correct option is option ( A).

Firstly , we discuss how to check absolutely convergent , divergent or conditionally convergent.

Steps to Determine :

Step 1: Take the absolute value of the series. Then determine whether the series converges.

If it converges, then we say the series converges absolutely.

If it does not converge, then we say it does not converge absolutely and we follow to Step 2

Step 2: Use the Alternating Series Test to determine whether the original series converges or diverges.

If it converges, then we say the series converges conditionally.

If the Alternating Series Test fails, we attempt another test.

Absolute Convergence Test :

If ∑∞ |an| converges, then ∑∞ aₙ converges

n = 1 n =1

We say that ∑∞ aₙ converges absolutely

n=1

if this case is true. If a series does not converge absolutely but converges by another test, we say that the series converges conditionally.

The Alternating Series Test: An alternating series, ∑∞( −1)⁽ⁿ⁻¹⁾aₙ , converges if the following 3

we have given that

a) ∑∞ |aₙ₊₁/aₙ| = 5 >1

n = 1

Ratio Test: If 0 < aₙ and limn→∞(aₙ₊₁/aₙ) < 1, then an converges.If the limit is greater than 1, then

the series diverges. And if the limit is equal to 1, then the test gives no information.

so, it is divergent

b) ∑∞ |aₙ₊₁ /aₙ| = 0.5 <1
