The number of  individuals will need to be sampled to have a 90% confidence interval with a margin of error no more than 5% is at least 246.

To determine the sample size needed for a 90% confidence interval with a margin of error no more than 5%, we can use the formula:

n = (\(z^{2}\) * p * q) / \(E^{2}\)

where:
n = sample size
z = z-score for the desired confidence level (in this case, 1.645 for 90%)
p = proportion of individuals who believe global warming is not a problem (0.8)
q = 1 - p (0.2)
E = margin of error (0.05)

Plugging in these values, we get:

n = (\(1.645^{2}\)* 0.8 * 0.2) / \(0.05^{2}\)
n ≈ 246

Therefore, at least 246 individuals will need to be sampled to have a 90% confidence interval with a margin of error no more than 5%. The answer is at least 246.

The p-value can be found with the F-distribution table or statistical software. If the p-value is less than or equal to α, then answer is option (a),If the p-value is greater than α, then answer is option (b).

To determine the correct statistical decision based on the given F-statistic, F (3, 12) = 2.72, we need additional information such as the significance level (α) of the hypothesis test. The significance level is a predetermined threshold that is used to assess the statistical significance of the results.

The correct decision depends on whether the calculated p-value, which quantifies the strength of evidence against the null hypothesis, is less than or equal to the significance level (α).

To find the p-value, you would need the F-distribution table or statistical software.

Once you have the p-value, you can compare it to the significance level (α) to make a decision:

If the p-value is less than or equal to α, you would reject the null hypothesis, indicating a statistically significant mean difference.

If the p-value is greater than α, you would fail to reject the null hypothesis, suggesting that there is not a statistically significant mean difference.

Therefore, without the significance level or the p-value, it is not possible to determine the correct statistical decision.

Answer:

D

Step-by-step explanation:

The problem is put in different fractions to make it more confusing.

1 1/15 miles+ 1 3/5 miles+ 1 2/3 miles

We can find the common denominator of all of the fractions.

\(1 \frac{1}{15} + 1 \frac{9}{15} + 1 \frac{10}{15} \\= 3+\frac{20}{15} =4 \frac{5}{15}\\\\=\)4  1/3

\(monday = 1 \frac{1}{15} \)

\(tuesday = 1 \frac{3}{5} \)

\(wednesday = 1 \frac{2}{3} \)

the total number of miles Kenya ran in 3 days.

\( \frac{16}{15} + \frac{8}{5} + \frac{5}{3} \)

\( = \frac{16}{15} + \frac{8 \times 3}{5 \times 3} + \frac{5 \times 5}{3 \times 5} \)

\( = \frac{16 + 24 + 25}{15} \)

\( = \frac{65}{15} = \frac{13}{3} \)

\( = 4 \frac{1}{3} \)

therefore, the correct answer is option D.

The standard form of a number is a way of writing it as a number between 1 and 10 multiplied by a power of 10.

To convert \(13 \times 10^5\) to standard form, we need to move the decimal point 5 places to the right to get:

Since the decimal point is between the 1 and the 3, we can write this as:

Therefore, \(13\times 10^5\) in standard form is \(1.3 \times 10^6\).

The difference in the account balances at the end of the loan terms is $313.98.

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.

The formula for calculating compound interest is:

A = P * (1 + r/n)^(nt)

where:

A is the final amount after t years,

P is the principal amount,

r is the interest rate,

n is the number of times the interest is compounded per year, and

t is the number of years.

P = $12,000, r = 3.75% = 0.0375, n = 12, t = 66 months = 5.5 years

A = P * (1 + r/n)^(nt)

A = 12,000 * (1 + 0.0375/12)^(12*5.5)

A = 12,000 * (1 + 0.0375/12)^66

A =  12,000 * (1.003125)^66

A = $14,743.98

difference =$14,743.98 - $14,430 = $313.98

Step-by-step explanation:

Just below the solid line, there is the remainder and just above the solid line, there is a multiple of 12.

The number with a negative sign is being subtracted to the above number.

The first subtraction is mentioned as

5496-4800=696, observe that 696 is just below the solid line.

Now, proceeding further in the same way, the number below the second solid line is 96 which is obtained when the number in the box is being subtracted to the above number 696.

Let the number in the box is \(x\). So,

\(696-x=96\)

In binary representation, each bit can be either 0 or 1. Using five binary bits, we can obtain 32 different numbers. Therefore, the correct answer is (B).

With five binary bits, we have five positions, and each position can have two possibilities (0 or 1). To calculate the total number of different numbers we can obtain, we need to raise 2 to the power of the number of bits. In this case, we have \(2^5,\) which equals 32. Therefore, we can obtain 32 different numbers using five binary bits. To understand this concept, we can think of each binary bit as a switch that can be either on (1) or off (0). With five switches, we have a total of 32 different combinations or numbers that can be represented. These numbers range from 0 (all switches off) to 31 (all switches on). Therefore, the correct answer is (B), which states that we can obtain 32 different numbers using five binary bits.

Answer:

a) 5p (or 5q)

b) 5p ( or 5q)

c) 10p (or 10q)

Step-by-step explanation:

We will use the following information for solving and using the given figure

Preliminary computation

We have \(\overrightarrow{AB} = \overrightarrow{BC}\)

Therefore 4p + q = 5p

5p = 4p + q

5p-4p = q

p = q

\(\overrightarrow{AB} = 4p + q = 4p + p = 5p = 5q\\\)

So each side is 5p in length which is also equal to 5q since p = q

Part a

\(\overrightarrow{AO} = \overrightarrow{OA} = \overrightarrow{AB} = 5p\)  (same as 5q)

Part b

\(\overrightarrow{OB} = \overrightarrow{OA} = 5p\)   (same as 5q)

Part c
\(\overrightarrow{EB} = 2 \cdot \overrightarrow{OB} = 2 \cdot 5p = 10p\)   (also 10q)

the C-CAPM with power utility and lognormal consumption growth predicts that the representative agent in country A will consume more in the current period and that the price of an identical financial asset will be lower compared to country B.

The C-CAPM is a financial model that relates the consumption patterns and asset prices in an economy. In this scenario, the difference in subjective discount factors implies that the representative agent in country A values future consumption relatively less compared to country B. As a result, the representative agent in country A tends to consume more in the current period, prioritizing immediate consumption over saving for the future.

Furthermore, the C-CAPM suggests that the price of an identical financial asset, such as a stock or bond, will be lower in country A. This is because the higher subjective discount factor in country A implies a higher expected return requirement for investors. As a result, investors in country A will demand a higher risk premium, leading to a lower price for the financial asset.

The table represents a quadratic function if and only if f(h - d) = f(h + d), where d is the distance of the x-value with respect to the x-coordinate of the vertex of the parabola, represented by the variable h.

Quadratic functions are polynomials of the form y = a · x² + b · x + c, which can be rewritten on vertex form: y - k = a · (x - h)², where (h, k) is the vertex of the function. Graphically speaking, quadratic functions are parabolae.

The axis of symmetry passes through the function and therefore we can infer that the table given represents a quadratic function if and only if the following condition is met:

f(h - d) = f(h + d)      (1)

Where d is the distance of the x-value with respect to the x-coordinate of the vertex of the parabola, represented by the variable h. If all possible pairs observes (1), then we are in front of a quadratic equation.
