The approximate number of female members of the army reserve in 2019 was 75,467.
What is the number of female members in 2019?If 2 out of every 5 members of the army reserve were female, then the proportion of female army reserve personnel can be represented as:
= 2/5
= 0.4.
Now, we can multiply the proportion to total number of army reserve to get the number of female members which is:
= 0.4 x 188,667
= 75,466.80
= 75,467

In the given diagram, using one of the circle theorems, the value of x is 68°
Circle Geometry: Calculating the value of xFrom the question, we are to calculate the value of x in the given diagram.
The diagram shows a circle with O. The angle subtended at the center is 136°. We are to determine the value of the unknown angle x.
From one of circle theorems, we have that
The angle subtended by arc at the center of a circle is twice the angle at the circumference.
Therefore,
We can write that
136° = 2x
Solve for x in the above equation
136° = 2x
Divide both sides of the equation by 2
136° / 2 = 2x / 2
68° = x
Hence,

Given the triangle ABC at points A = ( 2, 2 ) B = ( 4, 5 ) C = ( 6, 3 ), and if the triangle is first reflected over the y axis, and then over the x axis, find the new point A''.
To reflect a point over the y-axis, we negate the x-coordinate of the point. To reflect the resulting point over the x-axis, we negate the y-coordinate of the point. So, to find the new point A'', we can perform these operations on the original point A:
1. Reflect A over the y-axis to get A': (-2, 2)
2. Reflect A' over the x-axis to get A'': (-2, -2)
Therefore, the new point A'' is (-2, -2).

The area under the curve (since the function of the parabolic expression is y = x - x²) is 1/6 square units.
What is a parabolic expression?A parabolic function has an expression represented as f(x) = ax² + bx + c, which allows solving for x using either the factorization method or applying the quadratic formula. By zeroing out this expression, it becomes possible to determine its roots as with any quadratic equation.
In the case of the above function:
To find the area under the curve, above the x-axis, we need to integrate the parabolic expression from 0-1
that is:
∫[0,1](x-x²)dx
This is evaluated using the power rule
∫[0,1](x-x²)dx = [1/2x² - 1/3x³) fro x= 0 to x = 1
inserting the limits of the integration, we have:
[1/2 (1) ² - 1/3 ( 1) ³] - [1/2 (0)² - 1/3 (0) ³]

David's gasoline station offers 4 cents off per gallon if the customer pays in cash and does not use a credit card. Past evidence indicates that 40% of all customers pay in cash. During a one-hour period, 15 customers buy gasoline at this station. What is the probability that more than 8 and less than 12 customers pay in cash?
The probability that more than 8 and less than 12 customers pay in cash is 0.376 or 37.6%.
What is the probability?The probability that more than 8 and less than 12 customers pay in cash is calculated using the binomial probability formula:
P(x) = (n choose x) * p^x * (1-p)^(n-x)where:
n is the number of trials = 15
x = customers who pay in cash
p = paying in cash, which is 0.4 according to the problem
The probability that more than 8 and less than 12 customers pay in cash. is the sum of the probabilities of 9, 10, and 11 customers paying in cash.
Using the binomial probability formula:
P(x) = (15Cx) * 0.4 * (1 - 0.4)¹⁵⁻ˣP(9) = 15C₉ * 0.4⁹ * 0.6⁶
P(9) = 0.212
P(10) = 15C₁₀ * 0.4¹⁰ * 0.6⁵
P(10) = 0.121
P(11) = 15C₁₁* 0.4¹¹ * 0.6⁴
P(11)= 0.043

To receive monthly payments of $1500 for 20 years, how much would a person have to invest now in an annuity with an annual interest rate of 3.1% to achieve this goal? Round the answer to the nearest dollar.
The person would have to invest approximately $461,044.94 now in an annuity with an annual interest rate of 3.1% to receive monthly payments of $1500 for 20 years.
To calculate the present value of an annuity, we can use the following formula:
[tex]PV = PMT \times \dfrac{(1 - (\dfrac{1}{(1 + r)^n})) }{ r}[/tex]
Where:
PV = present value of the annuity
PMT = monthly payment
r = annual interest rate
n = total number of payments
In this case, the PMT is $1500, the annual interest rate is 3.1%, and the number of payments is 20 years x 12 months per year = 240 payments.
First, we need to convert the annual interest rate to a monthly interest rate by dividing it by 12:
r = 3.1% / 12 = 0.2583%
Next, we can plug in the values and solve for PV:
PV = $1500 x [(1 - (1 / (1 + 0.2583%)²⁴⁰)) / 0.2583%]
PV = $1500 x [(1 - (1 / 1.002152²⁴⁰)) / 0.002583]
PV = $1500 x [(1 - (1 / 4.818681)) / 0.002583]
PV = $1500 x (0.7915 / 0.002583)
PV = $461,044.94
Therefore, the person would have to invest approximately $461,044.94 now in an annuity with an annual interest rate of 3.1% to receive monthly payments of $1500 for 20 years.

For the square:
A = LW
A = (5 ft)(5 ft)
A = 25 ft²
For one triangle:
A = [tex]\frac{BH}{2}[/tex]

Step-by-step explanation:
Lets use [tex]l[/tex] for length and [tex]w[/tex] for width.
The perimeter of a rectangular field is [tex]2l + 2w[/tex]. We can construct the following equations:
[tex]4w = l[/tex].
[tex]2l + 2w = 300.[/tex]
If we plug [tex]4w[/tex] in for [tex]l[/tex] into the second equation, we get:

[tex]2w+8w = 300.[/tex]

[tex]w= 30.[/tex]
Plug 30 in for [tex]w[/tex] into the first equation.

As the sled passes underneath a tree, a 6.2 kg mass of snow falls vertically and lands on the moving sled. Calculate the final velocity of the sled. Calculate the final velocity of the sled. Show your work.
Answer:
The final velocity of the sled is 4.317 m/s.
Before the snow,
Total mass of sled = 35 + 4.2 = 39.2 kg
Initial velocity of the sled = 5 m/s
Momentum = Mass × Velocity
= 39.2 × 5
= 196 kg m/s
After the snow,
Total mass = 35 + 4.2 + 6.2 = 45.4 kg
Let v be the final velocity.
By the law of conservation of momentum,
Momentum before snow = momentum after snow
196 = 45.4 v
v = 4.317 m/s
Hence the final velocity is 4.317 m/s.
