The population in the year 2040 is 31800.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
We have,
The exponential equation is y = m[tex]a^t[/tex].
Where t is a variable
Now,
In 2007 (t = 0). the population was 12,000.
y = 12000
This means,
12000 = m[tex]a^0[/tex]
12000 = m
And,
In 2019 (t = 12). the population was 23,000.
y = 23000
23000 = m[tex]a^{23}[/tex]
23000 = 12000 [tex]a^{23}[/tex]
23000/12000 = [tex]a^{23}[/tex]
1.92 = [tex]a^{23}[/tex]
[tex]1.036^{23}[/tex] = [tex]a^{23}[/tex]
a = 1.03
Now,
y = 12000 [tex]1.03^t[/tex]
The population in the year 2040.
i.e
t = 33
y = 12000 x [tex]1.03^{33}[/tex]
y = 12000 x 2.65
y = 31800
Thus,

What is a radical expression?A radical is a mathematical expression which contains the radical expression, '√', which represent a fractional indices of the form 1/n.
(2) The specified radical expression is presented as follows;
∛(x²·y²) × [tex]\sqrt[4]{x^5 \cdot y^3}[/tex]
Expressing the above radical expression in index form, we get;
∛(x²·y²) × [tex]\sqrt[4]{x^5 \cdot y^3}[/tex] = [tex]x^{\frac{2}{3} }\times y^{\frac{2}{3} } \times x^{\frac{5}{4} } \times y^{\frac{3}{4}}[/tex]
Adding the index of like variable terms, we get;
[tex]x^{\frac{2}{3} }\times y^{\frac{2}{3} } \times x^{\frac{5}{4} } \times y^{\frac{3}{4}} = x^{\frac{2}{3} + \frac{5}{4} } \times y^{\frac{2}{3} + \frac{3}{4} }[/tex]
(2/3) + (5/4) = (2×4 + 5×3)/12 = 23/12 = 1 11/12
Therefore; [tex]x^{\frac{2}{3} + \frac{5}{4} } = x^{\frac{23}{12} }[/tex]
2/3 + 3/4 = (2 × 4 + 3 × 3)/(12) = 17/12 = 1 5/12
Therefore; [tex]y^{\frac{2}{3} + \frac{3}{4} } = y^{\frac{17}{12} }[/tex]
Which indicates that we get; [tex]x^{\frac{2}{3} + \frac{5}{4} } \times y^{\frac{2}{3} + \frac{3}{4} } = x^{\frac{23}{12} } \times y^{\frac{17}{12} }[/tex]
Therefore; ∛(x²·y²) × [tex]\sqrt[4]{x^5 \cdot y^3}[/tex] = [tex]x^{\frac{23}{12} } \times y^{\frac{17}{12} }[/tex]
In radical form, we get; [tex]x^{\frac{23}{12} } \times y^{\frac{17}{12} } = \sqrt[12]{x^{23} \cdot y^{17}}[/tex](3) The functions, f(x) = √(3·x + 4) - 5, g(x) = (2·x - 1)
The composite function, f(g(x)) can be found as follows;
f(g(x)) = √(3·g(x) + 4) - 5 = √(3·(2·x - 1) + 4) - 5
f(g(x)) = √(3·(2·x - 1) + 4) - 5 = √((6·x - 3) + 4) - 5 = √(6·x + 1) - 5
The composite function, f(g(x)) is therefore; f(g(x)) = √(6·x + 1) - 5(4) (√(x - 1)) = x - 7
Squaring both sides, we get;
(√(x - 1))² = (x - 7)²
(√(x - 1))² = x - 1(x - 7)² = x² - 14·x + 49Therefore;
(√(x - 1))² = x - 1 = (x - 7)² = x² - 14·x + 49
x - 1 = x² - 14·x + 49
x² - 14·x + 49 - (x - 1) = 0
x² - 15·x + 48 = 0
The quadratic formula can be used to solve the above equation to get;
x = (-(-15) ± √((-15)² - 4×1×48))/(2 × 1) = (15 ± √(33))/2
x = (15 ± √(33))/2(5) 2·∛(x - 1) + 6 = 16
2·∛(x - 1) + 6 = 16
Subtracting 6 from both sides, we get;
2·∛(x - 1) + 6 - 6 = 16 - 6 = 10
2·∛(x - 1) = 10
∛(x - 1) = 10/2 = 5
∛(x - 1) = 5
∛(x - 1)^3 = 5^3
∛(x - 1)^3 = x - 1
5^3 = 125

Based on historical data, your manager believes that 32% of the company's orders come from first-time customers. A random sample of 80 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is less than 0.33?
Note: You should carefully round any z-values you calculate to 4 decimal places to match wamap's
approach and calculations.
(Enter your answer as a number accurate to 4 decimal places.)
Answers
The probability that the sample proportion is less than 0.33 is approximately 0.7422.
How to model sample proportion?The sample proportion of first-time customers can be modeled by a normal distribution with mean p, the true proportion of first-time customers, and standard deviation [tex]\sqrt{\frac{p(1-p)}{n}}[/tex], where n is the sample size.
In this case, p = 0.32, n = 80, and we want to find [tex]P(\hat{p} < 0.33)[/tex].
The standardized version of [tex]\hat{p}[/tex] is given by:
[tex]z = \frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
Substituting the values, we get:
[tex]z = \frac{0.33-0.32}{\sqrt{\frac{0.32(1-0.32)}{80}}} \approx 0.6579[/tex]
Using a standard normal distribution table (or a calculator or statistical software), we find that the probability of z being less than 0.6579 is approximately 0.7422.
Therefore, the probability that the sample proportion is less than 0.33 is approximately 0.7422.

When Cheryl's phone battery is 55% charged, she knows it will last for another 1.5 hours. If Cheryl's
phone battery loses its charge at a constant rate, how long, in hours, will it last when it is fully charged?
Answers
The battery will last 2.73 hours when it is fully charged
How to determine how long it will last when it is fully charged?The unit rate is the ratio of a certain number of units of one quantity to units of another quantity. Mathematically, the unit rate is one quantity divided by the other quantity
Since Cheryl's phone battery is 55% charged and it will last for another 1.5 hours. Thus, the rate will be:
rate = 1.5 hours/55% = 3/110 hour per %
When it is fully charged, that is 100%. Thus, it will take:
Time for 100% = (3/110) * 100% = 2 8/11 hours = 2.73 hours

A guy wire supporting a radio tower is positioned 145 feet up the tower. It forms a 45 angle with the ground. To the nearest tenth, about how long is the wire?.
Answers
The approximate length of the guy wire supporting the radio tower, as determined using trigonometry with the given information of a 45 degree angle and a height of 145 feet up the tower, is 145 feet.
We can use trigonometry to solve this problem. Let's call the length of the guy wire "x". The opposite side of the right triangle formed by the guy wire and the ground is 145 feet (the height of the tower where the guy wire is attached), and the angle opposite the guy wire is 45 degrees.
Using the trigonometric function tangent, we can set up the following equation:
[tex]tan(45)[/tex] = opposite / adjacent
where "opposite" is 145 feet and "adjacent" is the length of the guy wire, x. Simplifying this equation, we get:
1 = 145 / x
Multiplying both sides by x, we get:
x = 145
Therefore, the length of the guy wire is approximately 145 feet to the nearest tenth.

Answers
Answer: a. From the perspective of the 30-year-old male, the monetary value corresponding to surviving the year is -$154 (the cost of the insurance policy). The monetary value corresponding to not surviving the year is $99,805 (the death benefit payout).
b. If the 30-year-old male purchases the policy, his expected value can be calculated using the formula:
Expected Value = (Probability of Event A) * (Value of Event A) + (Probability of Event B) * (Value of Event B)
In this case, the probability of surviving the year and not surviving the year can be assumed to be the same, as we don't have any specific information on the individual's health or life expectancy. Therefore, the probabilities can be assumed to be 0.5 each.
Plugging in the values, we get:
Expected Value = (0.5) * (-$154) + (0.5) * ($99,805) = ($50,326)
So, the expected value for the 30-year-old male purchasing the policy is $50,326.

How to calculate a probability?A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.
The 36 total outcomes for the pair of dices is given as follows:
(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)(3,1), (3,2), (3,3), (3,4), (3,5), (3,6)(4,1), (4,2), (4,3), (4,4), (4,5), (4,6)(5,1), (5,2), (5,3), (5,4), (5,5), (5,6)(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)Out of these outcomes, three of them, (5,6), (6,5) and (6,6) have a sum greater than 10, hence the probability is given as follows:
p = 3/36
p = 1/12.
Then the expected number is given as follows:
E(X) = 108 x 1/12
E(X) = 9.
