Answer:

11.72 hours

Step-by-step explanation:

In a continuous exponential growth model, the formula for the size of the population at time t is given by:

N(t) = N₀ * e^(rt)

where N₀ is the initial population size, r is the growth rate parameter, and e is the mathematical constant approximately equal to 2.71828.

To find the time it takes for the population size to double, we can set N(t) equal to 2N₀ and solve for t:

2N₀ = N₀ * e^(rt)

Dividing both sides by N₀:

2 = e^(rt)

Taking the natural logarithm of both sides:

ln(2) = rt * ln(e)

Since ln(e) = 1:

ln(2) = rt

Solving for t:

t = ln(2)/r

Substituting the given growth rate parameter of 5.9% per hour:

t = ln(2)/(0.059) ≈ 11.72 hours

Therefore, it takes approximately 11.72 hours for the size of the population to double.

The sector areas of the grey and white areas are 159.09 in² and 41.87 in²

c) 22,727 units of agricultural production are required to obtain 50,000 units of energy.

d) we need 27,825 units of energy to produce 50,000 units of agricultural products.

a) According to the table, the coefficient of production for agriculture is 0.293, that is

The maximum amount that you should finance is $26701 (rounded to the nearest dollar).

We can use the formula for monthly payments on a loan:

PMT = (PV x r x (1 + r)ⁿ) / ((1 + r)ⁿ - 1)

where PMT is the monthly payment, PV is the principal amount (the amount financed), r is the monthly interest rate, and n is the total number of months.

We can rearrange this formula to solve for PV:

PMT = (PV x r x (1 + r)ⁿ) / ((1 + r)ⁿ - 1)

Substituting the given values:

PMT = $499

r = 4.6% / 12 = 0.0038333 (monthly interest rate)

n = 5 x 12 = 60 (total number of months)

We get:

PV = $499 x ((1 + 0.0038333)⁶⁰- 1) / (0.0038333 x (1 + 0.0038333)⁶⁰)

PV = $26700.902

Answer: Maya’s mix will be more lemony.

Step-by-step explanation:

          We see that both Jonathan and Maya mix 7 teaspoons of the powdered lemon mix. Since we are finding whose mix will be more lemony, we need to find the person who added less water since their mixture will be less diluted.

          This leads us to Maya, she only added 1 cup of water while Jonathan added 2 cups of water. Maya's mixture will have a higher concentration since she has a higher ratio of lemon to water than Jonathan.

Answer:

P((1 + r)^6) = 1,675.80

P((1 + r)^5) = 1,606.50

b) 1 + r = 266/255, so r = 11/255 = .04 = 4%

a) P((1 + 11/255)^5) = 1,606.50

Answer:

this is hard

Step-by-step explanation:

is it trigonometry?

The values of x, y and z in the given simultaneous equation is:

x = 4

y = 6

z = -3

The 3 simultaneous equations are given as:

x + 7y - z = 49

2x - 5y + 2z = -28

x - 6y=-32

Rearranging the first equation  gives:

x = 49 - 7y + z

2x - 5y + 2z = -28

x - 6y = -32

Substitute 49 - 7y + z into equations 2 and 3 to get:

2(49 - 7y + z) - 5y + 2z = -28

49 - 7y + z - 6y = -32

Convert the equation in terms of u and solving simultaneously gives:

y = 6 and z = -3

x = 49 - 7(6) + (-3)

As our determined t-score (2.77) is larger than the critical t-value (2.262), we disregard the null hypothesis in favor of the alternative one

Given data:

The 1980 mean weight (μ) was 180.4 pounds, while the 2023 sample mean weight (x) was 197.9 pounds;

additionally, the sample size (n) was 10 and the sample standard deviation (σ) was 20 pounds.

At a significance level of 0.05, we calculate the t-score by first dividing (x-μ)/(σ/sqrt(n)).

This gives us the value 17.5/6.32 or 2.77 for the t-score.

Afterward, it is necessary to find the critical t-value with a two-tailed test at a significance level α=0.05 in respect to having 9 degrees of freedom (df = n – 1 = 10 – 1 = 9).

This can be located through either a t-distribution table or an online calculator; the result displays the calculated critical t-value being approximately ±2.262.

As our determined t-score (2.77) is larger than the critical t-value (2.262), we disregard the null hypothesis in favor of the alternative one, signifying there is a glaringly significant disparity between the average mass of grown male adults from 1980 and 2023 which upholds the researcher's statement that since 1980, males in the U.S. have gotten heavier.
