Answer:

Move decimal points in 726.02, 3 points in the left direction

Step-by-step explanation:

Given

Quotient of 726.02 and 1000

This is represented as:

\(Quotient = \frac{726.02}{1000}\)

The denominator 1000 has 3 zeros.

This implies that the decimal points will be moved in the left direction by 3 points.

So:

\(Quotient = \frac{726.02}{1000}\)

\(Quotient = 0.72602\)

Answer:

To find the quotient of 726.02 and 1,000, move the decimal point in 726.02 three places to the left.

The answer to the simplified expression 4⁹/4³ in index form is derived to be equal to 4⁶

To simplify a fraction written in index form, you can first express the numbers in prime factorization form by writing both the numerator and denominator as a product of prime factors. Identify common prime factors in the numerator and denominator and cancel them out. Then write the remaining factors as a product in index form.

Given the fraction 4⁹/4³, we can simplify as follows:

4⁹/4³ = (4 × 4 × 4 × 4 × 4 × 4 × 4 × 4 × 4)/(4 × 4 × 4)

we can cancel out (4 × 4 × 4) from both the numerator and denominator, living us with;

4⁹/4³ = 4 × 4 × 4 × 4 × 4 × 4

4⁹/4³ = 4⁶

Therefore, the answer to the simplified expression 4⁹/4³ in index form is derived to be equal to 4⁶

What is Union and Intersection of a numbers?

The set of elements that are contained in either set X, set Y, or both sets X and Y is referred to as the union of two sets X and Y. The set of items that are a part of both sets X and Y is known as the intersection of two sets X and Y.

Given that:

In survey of students,

20 have dogs, 15 have cats, and 5 have both. 1 has a pet squirrel.

n(A)=Student who has dogs.

n(B)=Student who has cats.

and n(AUB)= Student who having both dogs and cats.

So,

n(A)=20

n(B)=15

n(AUB)=5

According to formula,

n(AUB)=n(A)+n(B)-n(A∩B)

i.e. n(A∩B)=n(A)+n(B)-n(AUB)

     n(A∩B)=20+15-5

     n(A∩B)=30

a. The 95% confidence interval is between 0.485 and 0.565.

b. About 95% of these confidence intervals will contain the true population proportion of Americans who favor the Green initiative and about 5% will not contain the true population proportion.

A confidence interval of proportions has the bounds given by the rule presented as follows:

\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)

In which the variables used to calculated these bounds are listed as follows:

For the confidence level of 95%, the critical value z is the value of Z that has a p-value of \(\frac{1+0.95}{2} = 0.975\), so the critical value is z = 1.96.

The parameters are given as follows:

\(n = 600, \pi = \frac{315}{600} = 0.525\)

The lower bound of the interval is given as follows:

\(0.525 - 1.96\sqrt{\frac{0.525(0.475)}{600}} = 0.485\)

The upper bound of the interval is given as follows:

---------------------------

A piece-wise function is a function that has multiple definitions, depending on the value of the input.

In this problem:

A car rental company charges a $30 per day that a car is rented, up to 5 days. Thus, between 0 and 5 days, the cost is given by:

\(C(d) = 30d, 0 \leq d \leq 5\)

A rental fee of $22 per  day is charged for a car that is rented between 6 and 10 days, inclusive. Thus, the cost is:

\(C(d) = 22d, 6 \leq d \leq 10\)

A car that is rented for 11  days or more has a fee of $17 per day. Then:

\(C(d) = 17d, d \geq 11\)

Then, combining the definitions, the piece-wise function is:

\(C(d) = 30d, 0 \leq d \leq 5\)

The area of the shaded sector of the circle will be 10π units².

Area of a sector of a circle = θ/360 × πr², where r is the radius of the circle and θ is the central angle.

As per the question, QR = 5 and m∠RQS = 4π/5 = 144°.

As per the given question given data:

θ = 4π/5

r = QR = 5

Substitute the values in the formula to get:

Area of sector of a circle = 144/360 × π(5)²

Area of sector of a circle = 1/4 × π(25)

Apply the multiplication operation, and we get

Area of a sector of a circle = 10π units²

The number of positive and negative real roots of the function

x³ - x² - x - 5 are 1 and 2 respectively.

What is Descartes' Rule?

Descartes' rule of sign is used to determine the number of real zeros of a polynomial function. It tells us that the number of positive real zeros in a polynomial function f(x) is the same or less than by an even numbers as the number of changes in the sign of the coefficients.

Number of positive real roots of f(x) ≤ Number of sign changes f(x)

Number of negative roots of f(x) ≤ Number of sign changes of f(-x)

According to the given questions:

The given polynomial function f(x) = x³ - x² - x - 5

We can observe the number of sign changes in the coefficients

The sign changes only once

hence there is one positive real root

Now, f(-x) = -x³ + x² - x + 5

Clearly sign changes 2 times evenly

Therefore the function has 2 negative real roots

Step-by-step explanation:

We are given a box that contains two white, two red, and two blue poker chips. We need to find the probabilities of certain events based on two chips being randomly chosen without replacement.

a: Both chips are of the same color

We can calculate this by finding the probability that both chips are white, both chips are red, or both chips are blue.

P(a) = P(both white) + P(both red) + P(both blue)

P(a) = (2/6) * (1/5) + (2/6) * (1/5) + (2/6) * (1/5)

P(a) = 1/15

b: Both chips are red

Since there are two red chips and we are choosing two chips without replacement, we can calculate this probability as follows:

P(b) = (2/6) * (1/5)

P(b) = 1/15

c: At least one chip is red or white

We can calculate this probability as 1 minus the probability that both chips are blue.

P(c) = 1 - P(both blue)

P(c) = 1 - (2/6) * (1/5) * (1/4)

P(c) = 11/30

We can also find the following probabilities using the addition rule and conditional probability:

P(b | a^c) = P(both chips are red given that they are not the same color)

P(b | a^c) = (2/6) * (1/5) * 2 / (4/5) * 3

P(b | a^c) = 2/9

P(c | a) = P(at least one chip is red or white given that both chips are of the same color)

P(c | a) = 1 - P(both blue)

P(c | a) = 1 - (2/6) * (1/5) * (1/4)

P(c | a) = 11/30

In summary, we calculated the probabilities of three events: both chips are of the same color, both chips are red, and at least one chip is red or white. We used different probability rules and conditional probability to find the probabilities of two additional events.

C = (1 - a)/(a + b) × y + (-a - b)/(a + b) × t*.

c = (1 - a) × (yd - t*) + b × yd

in the three-sector model, consumption (c) is given by the equation c = ayd + b(0)yd, where yd represents disposable income. yd is calculated by subtracting taxes (t*) from total income (y), so yd = y - t*.

to derive the equation c = (1 - a) × (yd - t*) + b × yd, we substitute yd = y - t* into the consumption equation:

c = a(y - t*) + b(0)(y - t*)

c = ay - at* + 0

c = ay - at*

since y = c + i + g, we can express y as y = c + i + g. rearranging this equation, we get c = y - i - g.

substituting y = c + i + g into the equation c = ay - at* gives:

c = a(c + i + g) - at*

c = ac + ai + ag - at*

further rearranging the equation, we get:

c - ac = ai + ag - at*

(1 - a)c = ai + ag - at*

c = (1 - a)(yd - t*) + byd

simplifying, we have:

c = (1 - a)yd - (1 - a)t* + byd

c = (1 - a)(yd - t*) + byd

c = (1 - a)(y - t*) + byd

c = (1 - a)y - (1 - a)t* + byd

c = (1 - a)y - at* + byd

c = (1 - a)y - at* + b(y - t*)

c = (1 - a)y - at* + by - bt*

c = (1 - a)y + by - at* - bt*

c = (1 - a + b)y - (a + b)t* (b) answer:

investment multiplier = 1 / (1 - (1 - b)(1 - a))

the investment multiplier represents the change in equilibrium consumption (c) due to a change in investment (i*). it is calculated using the formula 1 / (1 - (1 - b)(1 - a)).

the investment multiplier shows the relationship between changes in investment and the resulting changes in consumption. if the investment multiplier is greater than 1, an increase in investment will lead to a larger increase in consumption, indicating a positive relationship between investment and consumption.

equilibrium level of consumption (c) = (1 - a)/(a + b) × y + (-a - b)/(a + b) × t*

change in c due to a 2-unit change in investment = 2 × investment multiplier

given:

a = 0.9

b = 80

i* = 60

g* = 40

t* = 20

The given factorization is incorrect. The correct factorization of the polynomial is (10x-1)(x+5).

To check this, let's multiply the factors (10x-5)(x+1) using the distributive property:

(10x-5)(x+1) = 10x(x+1) - 5(x+1) = 10x² + 10x - 5x - 5 = 10x² + 5x - 5

As we can see, the result is not equal to the original polynomial 10x² + 49x - 5.

To factor the polynomial correctly, we can use either factoring by grouping, completing the square, or the quadratic formula. Factoring by grouping can be done as follows:

10x² + 49x - 5

= 10x² + 50x - x - 5

= 10x(x+5) - 1(x+5)

= (10x-1)(x+5)
