Fractional-reserve banking refers to a banking system in which bank reserves are only a fraction of total deposits. The correct option is (C)

Fractional reserve banking is a system in which banks only hold a fraction of the total deposits as reserves, while the rest is used for making loans. This means that bank reserves are only a fraction of the total deposits, with the remaining funds being lent out as loans. This practice allows banks to earn interest on the loans they make, but it also exposes them to risk if too many borrowers default on their loans. Overall, fractional reserve banking is defined as a system in which banks lend out more money than they hold in reserves, relying on the assumption that not all borrowers will default at the same time.

Step-by-step explanation:

The graph of f(x) = 4x is a parabola that opens upwards. Shifting the graph 1 unit upwards, reflecting the graph about the y-axis, and shifting the graph 6 units left will all result in new graphs that are transformations of the original graph. Therefore:

a. Shifting f(x) 1 unit upward: y = 4x + 1

b. Reflecting f(x) about the y-axis: y = -4x

c. Shifting f(x) 6 units left: y = 4(x - 6)

The equations of the graphs that result from the given transformations:

a. Shifting f(x) 1 unit upward.

The graph of f(x) = 4x is a parabola that opens upwards. Shifting the graph 1 unit upwards means that all the points on the graph are moved 1 unit upwards. The new equation of the graph is:

y = 4x + 1

b. Reflecting f(x) about the y-axis.

Reflecting the graph of f(x) = 4x about the y-axis means that the x-coordinates of all the points on the graph are negated. The new equation of the graph is:

y = -4x

c. Shifting f(x) 6 units left.

Shifting the graph of f(x) = 4x 6 units left means that all the x-coordinates of all the points on the graph are decreased by 6. The new equation of the graph is:

y = 4(x - 6)

The arc length of the polar curve r = e^5θ from 0 to 2π is √26 [(e^10π - 1) / 5].

To find the arc length of a polar curve, we use the formula:

L = ∫[a,b] √(r(θ)² + [dr(θ)/dθ]²) dθ

where r(θ) is the polar equation of the curve, and dr(θ)/dθ is its derivative with respect to θ.

In this case, we have r(θ) = e^5θ, so:

dr(θ)/dθ = 5e^5θ

Plugging these into the arc length formula, we get:

L = ∫[0,2π] √(e^10θ + (5e^5θ)²) dθ

Simplifying the integrand, we have:

L = ∫[0,2π] √(e^10θ + 25e^10θ) dθ

L = ∫[0,2π] √(26e^10θ) dθ

L = √26 ∫[0,2π] e^5θ dθ

Using the formula for the integral of e^x, we get:

L = √26 [e^5θ / 5] |_0^(2π)

L = √26 [(e^10π - 1) / 5]

So the arc length of the polar curve r = e^5θ from 0 to 2π is √26 [(e^10π - 1) / 5].

Step-by-step explanation:

the average rate of change of f(x) in the closed interval [ a, b ] is

\(\frac{f(b)-f(a)}{b-a}\)

here [ a, b ] = [3, 6 ] , then

f(b) = f(6) = \(3^{6}\) + 17 = 729 + 17 = 746

f(a) = f(3) = 3³ + 17 = 27 + 17 = 44 , then

average rate of change = \(\frac{746-44}{6-3}\) = \(\frac{702}{3}\) = 234

Answer:

C choice.

Step-by-step explanation:

Since line a is given a slope as -4.

Another line which is line b is given that it's perpendicular to line a or we can say that line a is perpendicular to line b.

Perpendicular is defined as:

\( \displaystyle \large{m_1m_2 = - 1}\)

Both slopes multiply and yield -1.

We know that m1 is -4; we want to find m2 which is slope of line b.

\( \displaystyle \large{ - 4m_2 = - 1}\)

Divide both sides by -4.

\( \displaystyle \large{ \frac{ - 4m_2}{ - 4} = \frac{ - 1}{ - 4} } \\ \displaystyle \large{ m _2 = \frac{1}{4} }\)

Therefore, the slope for line b is 1/4.

Thus, the C choice is correct.

The correct value of probability is P(X <= 140) - P(X <= 165).

To calculate the quantities related to the probability of developing a lung disease among smokers, we can use the binomial distribution.

Expected number of people suffering from lung disease:The expected number of people suffering from lung disease is given by the product of the probability and the number of smokers examined:

Expected value = Probability * Sample size = 0.18 * 1000 = 180.

Standard deviation of the number of people with lung disease:

The standard deviation of a binomial distribution is calculated using the formula:

Standard deviation = sqrt(n * p * (1 - p)),

where n is the sample size and p is the probability of success.

Standard deviation = sqrt(1000 * 0.18 * (1 - 0.18)) = 11.21.

Probability of finding more than 135 people with lung disease:

To find the probability of more than 135 people with lung disease, we can calculate the cumulative probability of 135 or fewer people and subtract it from 1.

Using a binomial distribution calculator or table, we can find the cumulative probability of 135 or fewer people with lung disease. Let's say this cumulative probability is P(X <= 135). Then, the probability of more than 135 people with lung disease is:

Probability = 1 - P(X <= 135).

Probability of the number of infected people being between 165 and 140:

To find the probability of the number of infected people being between 165 and 140, we need to calculate the cumulative probability of 140 or fewer people and subtract the cumulative probability of 165 or fewer people.

Using a binomial distribution calculator or table, let's say the cumulative probability of 140 or fewer people with lung disease is P(X <= 140) and the cumulative probability of 165 or fewer people is P(X <= 165). Then, the probability of the number of infected people being between 165 and 140 is:

Given the parameter values n, δ, A₀, and k₀, the endogenous technological progress A(t) can be calculated using a recursive formula. The value of physical capital k(t) can also be determined using a separate recursive formula. The specific values depend on additional parameters not provided.

To compute the value of the endogenous technological progress A(t) at time t, we can use the following recursive formula:

A(t+1) = (1 - δ) * A(t) + n * k(t)^θ

where:

- A(t) represents the value of technological progress at time t.

- δ is the depreciation rate, which is 0.1 in this case.

- n is the exogenous growth rate of technological progress, which is 0.01 in this case.

- k(t) is the value of physical capital at time t.

- θ is the elasticity of output with respect to capital, which is not provided in the given information.

To compute k(t), we can use the following formula:

k(t+1) = (1 - δ) * k(t) + i(t)

where:

- k(t) represents the value of physical capital at time t.

- δ is the depreciation rate, which is 0.1 in this case.

- i(t) is the investment at time t.

Since the investment i(t) is not given in the provided information, we cannot determine the exact values of A(t) and k(t) for each time period. However, we can use the given initial values to compute their values for the initial time period (t = 0).

Using the provided initial values:

A(0) = 5

k(0) = 10

We can substitute these values into the recursive formulas to compute A(1) and k(1):

A(1) = (1 - 0.1) * 5 + 0.01 * 10^θ

k(1) = (1 - 0.1) * 10 + i(0)

The values of A(1) and k(1) can then be used to compute A(2) and k(2), and so on, by iteratively applying the recursive formulas. The specific values of A(t) and k(t) for each time period would depend on the values of θ and the investment i(t), which are not provided.
