The salary $50,780 per year is lower than the yearly median.
The yearly median earnings for a male with a bachelor's degree are $40,404 higher than those for a male with a high school diploma.
a. As, the median weekly earnings for males with a bachelor's degree are $1,384.
To convert this to yearly earnings, we can multiply by the number of weeks in a year (52):
= $1,384 x 52
= $71,968
So, the salary $50,780 per year is lower than the yearly median earnings for a male with a bachelor's degree.
b. Now, The yearly median earnings for a male with a high school diploma (no college) are $607 per week. Converting this to yearly earnings:
Yearly median earnings for a male with a high school diploma
= $607 x 52 = $31,564
The difference between the yearly median earnings for a male with a bachelor's degree and a male with a high school diploma is:
= $71,968 - $31,564 = $40,404
So, the yearly median earnings for a male with a bachelor's degree are $40,404 higher than those for a male with a high school diploma.

help pls!! due today!
a. The rate of change of the relation is 2.
b. The value of n is 14.5.
How to calculate the rate of change (slope) of a line?In Mathematics and Geometry, the rate of change (slope) of any straight line can be determined by using this mathematical equation;
Rate of change (slope) = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Rate of change (slope) = rise/run
Rate of change (slope) = (y₂ - y₁)/(x₂ - x₁)
By substituting the given data points into the formula for the rate of change (slope) of a line, we have the following;
Rate of change (slope) = (y₂ - y₁)/(x₂ - x₁)
Rate of change (slope) = (10 + 1)/(3.5 + 2)
Rate of change (slope) = 11/5.5
Rate of change (slope) = 2
Part b.
Next, we would determine the value of n as follows;
2 = (43 - 32)/(20 - n)
2(20 - n) = 11
40 - 2n = 11
2n = 29
n = 14.5

Find the area of the region that lies inside both curves. r = 6sin(2θ), r = 6sin(θ)
The area of the region that lies inside both curves is 11π/3 - 9√3/2 square units.
The area of the region that lies inside both curves first need to find the points of intersection.
The two equations equal to each other and solve for θ:
6sin(2θ) = 6sin(θ)
Dividing both sides by 6 get:
sin(2θ) = sin(θ)
The identity sin(2θ) = 2sin(θ)cos(θ) can rewrite this as:
2sin(θ)cos(θ) = sin(θ)
Dividing both sides by sin(θ) we get:
2cos(θ) = 1
Solving for θ we get:
θ = π/3, 5π/3
The area of the region by integrating the function r with respect to θ from θ = π/3 to θ = 5π/3:
A = ∫[π/3, 5π/3] 1/2 r² dθ
r = 6sin(2θ) when 0 ≤ θ ≤ π and r = 6sin(θ) when π ≤ θ ≤ 2π.
Substituting the appropriate values of r and integrating, we get:
A = ∫[π/3, π] 1/2 (6sin(2θ))² dθ + ∫[π, 5π/3] 1/2 (6sin(θ))² dθ
= ∫[π/3, π] 27sin²(2θ) dθ + ∫[π, 5π/3] 18sin²(θ) dθ
= [9θ - 3/4 sin(4θ)]π/3π + [6θ - 9/2 cos(2θ)]π/5π
= (π/3)[9π/2 - 3√3] + (2π/3)[5 - 9√3/2]

If trapezoid JKLM is translated using the rule (x, y) → (x + 3, y − 3) and then translated using the rule (x, y) → (x − 1, y + 1) to create trapezoid J″K″L″M″, what is the location of L″?
The location of L″ is (-5, 0).
To find the location of L″, we first need to apply the first translation rule to the coordinates of trapezoid JKLM:
J': (x, y) → (x + 3, y - 3) => J'(-2+3, 1-3) = J(1, -2)
K': (x, y) → (x + 3, y - 3) => K'(1+3, 1-3) = K(4, -2)
L': (x, y) → (x + 3, y - 3) => L'(3+3, -2-3) = L(6, -5)
M': (x, y) → (x + 3, y - 3) => M'(-4+3, 2-3) = M(-1, -1)
Now, we need to apply the second translation rule to the coordinates of J', K', L', and M':
J'': (x, y) → (x - 1, y + 1) => J''(1-1, -2+1) = J''(0, -1)
K'': (x, y) → (x - 1, y + 1) => K''(4-1, -2+1) = K''(3, -1)
L'': (x, y) → (x - 1, y + 1) => L''(6-1, -5+1) = L''(5, -4)
M'': (x, y) → (x - 1, y + 1) => M''(-1-1, -1+1) = M''(-2, 0)

Mr. and Mrs. Doran have a genetic history such that the probability that a child being born to them with a certain trait is 3/4. If they have seven children, what is the probability that exactly three of their seven children will have that trait? Round your answer to the nearest thousandth.
The probability that exactly three of their seven children will have the given trait is 0.073.
To solve this problem, we can use the binomial probability formula. The probability of exactly k successes in n trials, where the probability of success is p, is given by:
P(X = k) = C(n, k) . [tex]p^k[/tex] . (1 - [tex]p)^(n - k)[/tex]
In this case, the probability of a child having the trait is p = 3/4, and we want to find the probability of exactly 3 children having the trait out of 7 children, so k = 3 and n = 7.
Using the formula:
P(3) = 7! / 4! 3! x (3/4)³ x (1-3/4)⁴
P(3) = 35 x 27/64 x 1/256
P(3) ≈ 0.073

We can see that (a^2+b^2)(x+y) - (a^2y+b^2x) simplifies to zero, which means the expression is true. Therefore, the polynomial identity (a^2+b^2)(x+y) - (a^2y+b^2x) holds.
To verify the polynomial identity (a^2+b^2)(x+y) - (a^2y+b^2x), we need to simplify the expression on both sides and show that they are equal.
Expanding (a^2+b^2)(x+y) using the distributive property, we get:
(a^2+b^2)(x+y) = a^2x + a^2y + b^2x + b^2y
Expanding (a^2y+b^2x), we have:
(a^2y+b^2x)
Now, let's subtract (a^2y+b^2x) from (a^2x + a^2y + b^2x + b^2y):
(a^2x + a^2y + b^2x + b^2y) - (a^2y+b^2x)

The density in gold is 27.2 grams per cm. A gold gar in the shape of a rectengular prism, has a length of 23.5 and a width of 28 cm. The mass of the entire bar is 43,892.5 grams. What is the height of the bar?
Answer:2.381 cm.
Step-by-step explanation:
The volume of the gold bar can be calculated using the formula for the volume of a rectangular prism:
Volume = Length x Width x Height
We know the length and width of the bar, so we can substitute those values:
Volume = 23.5 cm x 28 cm x Height
We can then solve for the height by rearranging the equation:
Height = Volume / (Length x Width)
To find the volume, we can use the density of gold and the mass of the bar:
Density = Mass / Volume
Volume = Mass / Density
Substituting the values we have:
Volume = 43,892.5 g / 27.2 g/cm³
Volume = 1610.049 cm³
Now we can substitute the volume into the equation we derived earlier to solve for the height:
Height = 1610.049 cm³ / (23.5 cm x 28 cm)
Height = 2.381 cm
Therefore, the height of the gold bar is approximately 2.381 cm.

To find out if the fractions are proportional, we need to check if their cross-products are equal.Cross-product of 3/5 and 9/15:
3/5 × 9/15 = (3 × 9)/(5 × 15) = 27/75We can simplify 27/75 by dividing both the numerator and denominator by their greatest common factor, which is 3:
27/75 = (3 × 9)/(3 × 25) = 9/25Therefore, the cross-product of 3/5 and 9/15 is 9/25.Since the cross-products are not equal to each other, the fractions are not proportional.
The difference in length of a spring on a pogo stick from its non-compressed length when a teenager is jumping on it after θ seconds can be described by the function f of theta equals 2 times cosine theta plus radical 3 period
Part A: Determine all values where the pogo stick's spring will be equal to its non-compressed length. (5 points)
Part B: If the angle was doubled, that is θ became 2θ, what are the solutions in the interval [0, 2π)? How do these compare to the original function? (5 points)
Part C: A toddler is jumping on another pogo stick whose length of their spring can be represented by the function g of theta equals 1 minus sine squared theta plus radical 3 period At what times are the springs from the original pogo stick and the toddler's pogo stick lengths equal? (5 points)
Answer:
Hope this helps ^^
Step-by-step explanation:
Part A: To determine the values where the pogo stick's spring will be equal to its non-compressed length, we set the function equal to zero:
f(θ) = 2cos(θ) + √3
To find the values of θ that satisfy this equation, we solve:
2cos(θ) + √3 = 0
Subtracting √3 from both sides:
2cos(θ) = -√3
Dividing by 2:
cos(θ) = -√3/2
Using the unit circle, we can find the angles where cosine is equal to -√3/2. These angles are π/6 and 11π/6.
Therefore, the values where the pogo stick's spring will be equal to its non-compressed length are θ = π/6 and 11π/6.
Part B: If the angle θ is doubled, that is, θ becomes 2θ, we substitute 2θ into the original function:
f(2θ) = 2cos(2θ) + √3
Using the double angle formula for cosine:
f(2θ) = 2(2cos²(θ) - 1) + √3
Expanding and simplifying:
f(2θ) = 4cos²(θ) - 2 + √3
Comparing this to the original function f(θ), we see that the new function has the same form but with different coefficients. The solutions for f(2θ) in the interval [0, 2π) will be the same as the solutions for f(θ), but they will occur at double the angles. In other words, if θ is a solution for f(θ), then 2θ will be a solution for f(2θ).
Part C: To find the times when the lengths of the springs from the original pogo stick and the toddler's pogo stick are equal, we set the two functions equal to each other:
f(θ) = g(θ)
2cos(θ) + √3 = 1 - sin²(θ) + √3
Rearranging the equation:
sin²(θ) + 2cos(θ) = 0
Using the Pythagorean identity sin²(θ) = 1 - cos²(θ), we substitute:
1 - cos²(θ) + 2cos(θ) = 0
Rearranging and simplifying:
cos²(θ) - 2cos(θ) + 1 = 0
Factoring:
(cos(θ) - 1)² = 0
Taking the square root:
cos(θ) - 1 = 0
cos(θ) = 1
This occurs when θ is a multiple of 2π.
Therefore, the lengths of the springs from the original pogo stick and the toddler's pogo stick are equal at θ = 2πn, where n is an integer.

c. The ball has hit the ground in 4 seconds.
d. The ball has hit the ground in 2 seconds.
e. The ball was tossed from the building at 30 feet.
Answer:
Step-by-step explanation:
Set h=0 for ground height, then solve for t
-16t^2 -20t +240 = 0
divide by -4
4t^2 +5t - 60 = 0
use the quadratic formula
t= -5/8 + or - (1/8)square root of (25 +4(4)(60)). Ignore the negative square root
=-5/8 + (1/8)sqr(960+25)
= -5/8 + (1/8)sqr(985)
=-5/8 + (1/8)sqr(5(197))= slightly less than -5/8 +(10/8)(sqr10) = about -5/8 +32/8 = 27/8 = 3.3 seconds
the ball's initial velocity is negative, meaning the ball was thrown downward. Then add the effect of gravity, and it should hit the ground in a short time, even when thrown from an initial height of 240 feet.
plug t=2 into the original equation for height. You should get slightly above ground, near zero
-16(2)^2 -20(2) +240 = -64 -40+240 = 136
try t=3
-16(9) -20(3) +240 = -144 -60 +240 = 36
try t=4
-16(16) -20(4) +240 =-256 -80 +240 =-96
the time to hit ground should be between t=3 and 4, but closer to t=3, maybe about 3 1/3 seconds

new population in 2020 = 187 950 - 8,463 = 179,487
overall percent change in the population
Percent change = (New population - Initial population) / Initial population * 100
Percent change = (179,487 - 175,000) / 175,000 * 100
Percent change = 4,487 / 175,000 * 100
Percent change ≈ 2.56

HELP FAST PLEASE!
I do not understand please help and explain which ordered pair of 4 options represents a function.
Answer:
third option represents a function.
Step-by-step explanation:
for the ordered pairs to represent a function.
each value of x must only map to one unique value of y
in the first option
(- 2, 0 ) and (- 2, 2 )
the same x- coordinate maps to 2 different values of y
thus not a function.
in the second option
every value of x = - 5 maps to 5 different values of y
thus not a function.
in the third option
each value of x maps to a unique value of y.
thus a function.
in the fourth option
(- 6, - 3 ) and (- 6, - 2 )
the same x value maps to 2 different values of y
thus not a function.
pls help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The length of the other diagonal of the kite is: 50 cm
What is the Area of a Kite?We want to find the area of the given kite but It should be noted that:
The hypotenuse is usually the slanted line part in a triangle.
Area of a kite = pq/2
where:
p and q are diagonals
We are given:
Area of Kite = 180 cm²
Length of diagonal = 16 cm
Thus:
16q = 180
q = 180/16
q = 50 cm
This gives us the length of the other diagonal of the kite

What is an exponential function?In Mathematics and Geometry, an exponential function can be modeled by using this mathematical equation:
[tex]f(x) = a(b)^x[/tex]
Where:
a represents the initial value or y-intercept.x represents x-variable.b represents the rate of change, common ratio, or growth rate.Based on the graph, we would calculate the value of a and b as follows;
f(x) = a(b)^x
10 = a(b)⁰
a = 10
Next, we would determine value of b as follows;
12 = 10(b)¹
12 = 10b
b = 12/10
b = 1.2
Therefore, the required exponential function is given by;
[tex]y = 10(1.2)^x[/tex]
Part a.
When x = 0, the y-intercept can be determined as follows;
[tex]y = 10(1.2)^0[/tex]
y = 10(1)
y = 10.
Part b.
By critically observing the graph shown in the image attached above, we can reasonably and logically deduce the following domain and range:
Domain = [-∞, ∞].
Range = [0, ∞] or {y | y ≥ 0}
Part c.
By critically observing the graph shown in the image attached above, we can reasonably and logically deduce that the exponential function is always increasing over the interval [-∞, ∞].
Part d.
In conclusion, this exponential function is an even function because it is symmetric with respect to the y-coordinate (y-axis).

Find the area of the parallelogram with vertices L(–5, –2, –4), M(–12, –2, –4), N(–12, –8, –10), and O(–5, –8, –10).
From the vertices provided, the area of the parallelogram is 42cm².
How do we calculate the area of a parallelogram with the vertices provided?The area of a parallelogram remain
Area = base×height
we need to start by creating two vectors using the given vertices. We can use LM and LN.
Vector LM = M - L = (-12, -2, -4) - (-5, -2, -4) = (-7, 0, 0)
Vector LN = N - L = (-12, -8, -10) - (-5, -2, -4) = (-7, -6, -6)
LM x LN = (0×(-6) - 0×(-6), 0×(-7) - (-7)×0, -7×(-6) - 0×0)
= (0, 0, 42)
Area = ||LM x LN|| =√(0² + 0² + 42²) = √(0 + 0 + 1764)
= √(1764) = 42 cm²
