Answer: The interest rates charged in both formulas are different.

Step-by-step explanation:

To begin with, the simple interest = PRT/100

In this, the interest is the same as the number of years.

For example, P=10,000 R=10% T=2yrs

SI = PRT/100

    = 10,000*10*2/100

    = 2000

This rupee 2000 is the same interest for two years.

compound interest = A= P(1+r/100)^n

In this, the interest changes every year up to the period of time.

For example, P= 10,000 R=10% N=2yrs

A= 10,000(1+10/100)^2

  = 10,000*11/10*11/10

   = 12100

I= A-P

 =12100-10000

 = 2100

This interest varies for 2 years.

The choice that shows 13 · (7 · 4) correctly rewritten using the associative property and then correctly simplified is presented as follows;

The associative property of multiplication stated that the multiplication of three numbers produces the same result in any way the numbers are grouped.

Mathematically, the associative property of multiplication can be presented as follows;

(a × b) × c = a × (b × c)

The specified operation involving the multiplication of three numbers are presented as follows;

13 · (7 · 4)

The associative property of multiplication indicates that we get;

13 · (7 · 4) = (13 · 7) · 4

13 × 7 = 91

A prism's volume is calculated using the formula V=Bh, where B denotes the base area and h the height. A rectangular area makes up the prism's base. The rectangle's dimensions are 9 cm long by 7 cm wide. The formula V=Bh, where V stands for volume, B for the prism's area at its base, and h for its height, can be used to determine a prism's volume.

Using the mathematical operations of addition and subtraction, the quantity of almond milk that Lucas should add to his recipe to make three 8-fluid-ounce servings of the smoothie is 1¹/₈ cups.

Mathematical operations include addition, division, subtraction, and multiplication.

In this situation, we can determine the needed quantity of almond milk using multiplication, subtraction, and addition.

The total quantity of smoothie is obtained by multiplying three cups by 8 fluid ounces.  The quantity of almond milk is determined by subtracting the sum of other ingredients from the total quantity.

Lucas' usual recipe for two 8 fluid ounces:

Berries 3/8 cups

Mango 1/2 cups

Yogurt = 3/4 cups

Almond Milk = 3/8 cups

Total cups made = 2 cups (16 fluid ounces = 2 x 8)

New recipe for three 8 fluid ounces:

Berries 5/8 cups

Mango 1/2 cups

Yogurt = 3/4 cups

Almond milk = x

1 cup = 8 fluid ounces

Total cups to be made = 3 cups (24 fluid ounces = 3 x 8)

5/8 + 1/2 + 3/4 + x = 24/8

= 15/8 + x = 24/8

x = 9/8 (24/8 - 15/8)

The graph of the given piecewise function is as attached below.

Piecewise function is a function consisted of pieces of different functions over different intervals.

From the case we have:

f(x) = 3x - 5 if x ≤ -1

f(x) = -2x + 3 if -1 < x < 4

f(x) = 2 if x ≥4

To construct the piecewise function, we can try to find the base points of each functions.

f(x) = 3x - 5; if x ≤ -1

We will take x = -1 to approximate the line position

f(-1) = 3(-1) - 5

f(-1) = -3 - 5 = -8

f(x) = -2x + 3; if -1 < x < 4

(x = -1)

f(-1) = -2 (-1) + 3

f(-1) = 2 + 3 = 5

(x = 4)

f(4) = -2 (4) + 3

f(4) = -8 + 3 = -5

f(x) = 2; if x ≥ 4

(x = 4)

f(4) = 2

Step-by-step explanation:

Given quadratic equation:

[tex]x^2-7x-18=0[/tex]

To factor a quadratic in the form ax²+bx+c, first find two numbers that multiply to ac and sum to b.

[tex]\implies ac=1 \cdot -18=-18[/tex]

[tex]\implies b=-7[/tex]

Therefore, the two numbers are: -9 and 2.

Rewrite b as the sum of these two numbers:

Factor the first two terms and the last two terms separately:

[tex]\implies x(x-9)+2(x-9)=0[/tex]

Factor out the common term (x - 9):

Step-by-step explanation: PQS = (7x - 6)°

SQR = (4x + 15)° since QS bisect PQR these two expressions must be equal

so

7x - 6 = 4x + 15 transfer like terms to the same side of the equation

7x - 4x = 15 + 6

3x = 21 divide both sides by 3

x = 7

also the sum of these two would give us the measure of PQR

7x + 4x + 15 - 6 = PQR

11x + 9 = PQR replace x with 7

11*7 + 9 = 86 this is the measure of angle PQR and also supplementary to PQT so the measure of PQT = 180 - 86

Step-by-step explanation:

You have N varying jointly with P1 and P2, such that N=109,000 for P1=74000 and P2=189000. You want to know N for P1=125000 and P2=175000.

The relation "N varies jointly with P1 and P2" can be described by the equation ...

  N = k·P1·P2

The value of k can be found as ...

  k = N/(P1·P2)

  k = 109000/(74000·189000) ≈ 7.793508×10^-6

Then the number of calls given the populations P1=125000 and P2=175000 is predicted to be ...

  N = (7.793508×10^-6)(125000)(175000) ≈ 170482.982...

  N ≈ 170483

About 170,483 calls are expected between cities with populations of 125 and 175 thousand.

If the number of phone calls between two nearby cities during a given time period. The number of calls  that are made between two cities with population 125,000 and 175,000 is: 170,482,987,500.

Calls  made between two cities with populations 74,000 and 189,000,

Call = 109,000/(74000 × 189000)

Call = 109,000 / 13,986,000,000

Call = 7.793508

Calls made between two cities with populations 125,000 and 175,000?

Calls =  7.793508 × 125000 ×175000

And the 3 consecutive numbers are 13, 14, and 15.

Here we know that the sum of three consecutive integers is 42.

If the first number is x, then the two consecutive numbers are:

x + 1

x + 1 + 1 = x + 2

Then the sum of these 3 consecutive numbers can be written as:

x + (x + 1) + (x + 2)

And that is equal to 42, then the equation is:

x + (x + 1) + (x + 2) = 42

So the first option is the correct one.

We know that Nevaeh initially deposited $2,100, and now she has $2,131.50 in her account. The interest earned is $2,131.50 - $2,100 = $31.50. To find out how many months has she been investing her money, we can use the following formula:

Time (in months) = (Interest / Principal) x (12 / Interest Rate)

Where Principal is the initial deposit amount, Interest Rate is the annual interest rate, and Interest is the amount of interest earned.

Plugging in the given values, we get:

Time (in months) = ($31.50 / $2,100) x (12 / 0.06)

Time (in months) = 0.0149 x 200

Time (in months) = 2.98

Since time cannot be in fraction of months, it has to be rounded off. So, Nevaeh has been investing her money for approximately 3 months.

The conversion from cents to Dollar we get :

4 cent  = 4/100 = $ 0.04

204 cents = 204/100 = $ 2.04 = $2 and 4 cents

.75 cents = .75 / 100 = $ 0.0075

3009 cents = 3009/100 = $ 30.09 = $30 and 9 cents

A conversion factor is a number that is used to multiply or divide one set of units into another. If a conversion is required, it must be done using the correct conversion factor to get an identical value. For instance, 12 inches equals one foot when converting between inches and feet.

Anazlysing the conditions given in the question we can  conclude that there is a statistically significant increase in the consensus estimate of economists.

Financial analysts often use the whisper number, which is a late-breaking estimate of a key economic indicator, to make predictions about the stock market and inform their investment decisions. They may use it to identify potential opportunities for buying or selling stocks based on whether the whisper number is higher or lower than expected.

While the whisper number can provide insight into the current economic conditions, it is not a foolproof way to predict the stock market. It is just an estimate based on a sample of economists' predictions and can be affected by various unpredictable factors. Therefore, it's important to take other economic indicators and market conditions into account when making investment decisions.

To conduct a hypothesis test, we need to first define the null hypothesis and alternative hypothesis.

Null Hypothesis: The whisper number (sample mean) is equal to the consensus estimate (population mean)

H0: μ = 250,000

Alternative Hypothesis: The whisper number (sample mean) is greater than the consensus estimate (population mean)

H1: μ > 250,000

The next step is to calculate the test statistic and p-value. We can use a one-tailed t-test since the sample size is less than 30 and we don't know the population standard deviation.

Test statistic:

t = (266,000 - 250,000) / (24,000 / sqrt(20))

P-value:

Using the t-distribution table with 19 degrees of freedom, the p-value is less than 0.01, which is the significance level we set.

Since the p-value is less than the significance level (0.01), we can reject the null hypothesis and conclude that there is a statistically significant increase in the consensus estimate of economists.
