Population The world population in 2000 was approximately 6.08 billion. The annual rate of increase was about 1.26%. If this rate of increase continues, what will be the approximate world population in 2050?
Answer:
Population in 2050 = 11,369,600,000
Step-by-step explanation:
Given:
Population in 2000 = 6,080,000,000
Rate of increase = 1.26%
Find:
Population in 2050
Computation:
Number of year = 50
Population in 2050 = Population in 2000[1+r]ⁿ
Population in 2050 = 6,080,000,000[1+1.26%]⁵⁰
Population in 2050 = 6,080,000,000[1.87]
Population in 2050 = 11,369,600,000
Harry’s tv plan cost 49.99 per month plus 3.49 per first run movie how many first run movies can he watch if he wants to keep his monthly bill to be a maximum of 100
Answer:
He can watch 14 first run movies to keep his monthly bill to be a maximum of $ 100.
Step-by-step explanation:
Given that Harry’s TV plan cost $ 49.99 per month plus $ 3.49 per first run movie, to determine how many first run movies can he watch if he wants to keep his monthly bill to be a maximum of $ 100, the following calculation must be performed:
100 - 49.99 = 50.01
50.01 / 3.49 = X
14.32 = X
49.99 + (3.49 x 14) = 98.85
Thus, he can watch 14 first run movies to keep his monthly bill to be a maximum of $ 100.

The r-value of the given data is 0.374.
What is a correlation coefficient?The correlation coefficient, denoted as r, is a statistical measure that describes the strength and direction of the linear relationship between two variables.
It ranges between -1 and +1, where -1 indicates a perfect negative correlation (inverse relationship), +1 indicates a perfect positive correlation (direct relationship), and 0 indicates no correlation between the variables.
We have,
First, we need to find the correlation coefficient (r) of the given data.
We can use the following formula to do this:
r = [n∑(xy) - (∑x)(∑y)] / [√{n∑x² - (∑x)²} √{n∑y² - (∑y)²}]
where n is the number of data points, x, and y are the respective variables, and ∑ denotes the sum of the values.
Using the given data, we can calculate the values as follows:
n = 5
∑x = 39
∑y = 53
∑(xy) = 442
∑x^2 = 483
∑y^2 = 1249
Substituting these values into the formula, we get:
r = [5(442) - (39)(53)] / [√{5(483) - (39)^2} √{5(1249) - (53)²}]
r = [2210 - 2067] / [√(2415) √(5660)]
r = 143 / (61.898 75.245)
r = 0.374 (rounded to three decimal places)
Therefore,
The r-value of the given data is 0.374.

A biologist studying trees constructed the confidence interval (0.14, 0.20) to estimate the proportion of trees in a large forest that are dead but still standing. Using the same confidence level, the interval was later revised because the sample proportion had been miscalculated. The correct sample proportion was 0.27. Which of the following statements about the revised interval based on the correct sample proportion is true?
A) The revised interval is narrower than the original interval because the correct sample proportion is farther from 0.5 than the calculated proportion is
B) The revised interval is narrower than the original interval because the correct sample proportion is closer to 0.5 than the mis-calculated proportion is
C) The revised interval is wider than the original interval because the correct sample proportion is farther from 0.5 than the mis-calculated proportion is
D) The revised interval is wider than the original interval because the corect sample proportion is closer to 0.5 than the mis-calculated proportion is.
E) The revised interval has the same width as the original interval.
Answer:
D) The revised interval is wider than the original interval because the corect sample proportion is closer to 0.5 than the mis-calculated proportion is.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
The larger the closer to 0.5 the value of [tex]\pi[/tex], the larger the margin of error and the wider the interval is.
A biologist studying trees constructed the confidence interval (0.14, 0.20)
This means that the estimate used was of:
[tex]\pi = \frac{0.14 + 0.2}{2} = \frac{0.34}{2} = 0.17[/tex]
The correct sample proportion was 0.27.
With [tex]\pi = 0.27[/tex], the margin of error is larger as 0.27 is closer to 0.5 than 0.17. Thus, the revised interval will be wider, and the correct answer is given by option D.

Name the coordinates of P(-8, 3) under a reflection across the y-axis.
Answer:
(8,3)
Step-by-step explanation:
Hello There!
This is the rule for reflection over y axis:
(x,y) -----> (-x,y)
So if the point (-8,3) we're to reflect over the y axis then the x value would stay the same but the sign would flip
So instead of -8 it would be +8
The y value does not change so the new coordinates would be

If a cylinder has a height of 5 and a volume of 98, what is the radius to the nearest tenth?
Answer:
r ≈ 2.5
Step-by-step explanation:
98 = 5(πr^2)
divide 5 by both sides
19.6 = πr^2
divide π by both sides
6.2388 = r^2
square root both sides
r = 2.49777
r ≈ 2.5
You hit a tennis ball with an initial vertical velocity of 25 m/s. The ball leaves the tennis racket 2 meters above the ground, h_o. How much time does your opponent have before the ball hits the ground on the other side of the net, h(t)? Use h(t) = -5t^2 + v_0t + h_0 where h(t) is the height of a tennis ball being hit h_0 is the initial height v_0 is the velocity in meters/second after time (t) in seconds
Answer:
here
Step-by-step explanation:
Solving a quadratic equation, it is found that your opponent has 5.08 seconds to react before the ball hits the ground on the other side of the net.
What is the quadratic equation for the ball's height?It is given by:
[tex]h(t) = -5t^2 + v_0t + h_0[/tex]
In which:
[tex]v_0[/tex] is the initial velocity of the ball.[tex]h_0[/tex] is the initial height of the ball.You hit a tennis ball with an initial vertical velocity of 25 m/s. The ball leaves the tennis racket 2 meters above the ground, hence [tex]v_0 = 25, h_0 = 2[/tex].
Then, the equation is:
[tex]h(t) = -5t^2 + 25t + 2[/tex]
It hits the ground when h(t) = 0, hence:
[tex]-5t^2 + 25t + 2 = 0[/tex]
The solutions are h = 5.08 and h = -0.08.
Since time is a positive measure, your opponent has 5.08 seconds to react before the ball hits the ground on the other side of the net.

Which of the following theorems verifies that ABC ~ STU?
Answer:
B. AA
Step-by-step explanation:
The diagram given shows that two angles in ∆ABC are congruent to two corresponding angles in ∆STU.
Invariably, the third unknown angle of both triangles would also be equal going by the third angle theorem.
Thus, based on the AA Similarity Theorem which says that two triangles are similar to each other if two corresponding angles of one is congruent to two angles in the other, ∆ABC ~ ∆STU.

b. As the sample sizeâ increases, the variance of decreases.â So, the distribution of becomes highly concentrated around.
c. As the sample sizeâ increases, the variance of increases.â So, the distribution of becomes highly concentrated around.
d. As the sample sizeâ increases, the variance of increases.â So, the distribution of becomes less concentrated around.
Answer:
b. As the sample size â increases, the variance of decreases. â So, the distribution of becomes highly concentrated around.
Step-by-step explanation:
Let : Yi,.... Yn are = i.i.d are random variables. The probability density of the distribution varies along with the sample size. When the sample size changes, the probability density of [tex]$E^3$[/tex] also changes.
The probability distribution may be defined as the statistical expression which defines the likelihood of any outcome for the discrete random variable and it can be opposed to the continuous random variable.
In the context, when the size of the sample of the distribution size increases, it causes a decrease in the variance and so the distribution becomes highly concentrated around.

Let's suppose A is the car with no 4-wheel drive
Let's suppose B is the car with third-row seats
As we know,
P(B|A) = n(A ∩ B)/n((A)
The probability that a randomly selected car with no 4-wheel drive has third-row seats:
From the table:
n(A ∩ B) = 12
n((A) = 40
P(B | A) = 12/40
P(B | A) = 0.3
Thus, the probability that a randomly selected car with no 4-wheel drive has third-row seats is 0.3 option (A) 0.3 is correct.

find the area of a circle if its circumference is 10 pi
Answer:
25π
Step-by-step explanation:
pi's symbol is π, which will be used sometimes to make it easier later
The circumference is equal to diameter multiplied by pi. (Diameter is the length across the circle, radius the center of the circle to an edge point aka. half the diameter, and circumference is the edge length aka. perimeter of the circle.)
We can then remove the pi off the 10, as the diameter multiplied by pi is the circumference, so the diameter is 10.
Half of 10 is 5, the radius.
The formula for area of a circle is radius squared times pi, remember easily by π r ^2
We can plug in the radius into the formula to get
π 5 ^2
And finish it by solving the square root to get
π 25
