There is a correlation between American women and being the main provider in their home.
What is Descriptive Statistics?Descriptive statistics, also known as brief informative coefficients, are used to summarize a specific data collection, which may be a sample of a population or a representation of the entire population. Descriptive statistics include measures of variability and central tendency (spread). Measures of central tendency include the mean, median, and mode, whereas measures of variability include the standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.
For instance, the sum of the following data set is 20: (2, 3, 4, 5, 6). A 4 (20/5) is the mean. A data set's mode is the number that appears most frequently, while its median is the value that is in the middle of the range of values. It is the value that separates a data set's higher values from lower values. There are many less common ways to use descriptive statistics, but they are nevertheless essential.

The transformed equation is:
F(x) = G(x + 2) = (x + 2)^2
So we can se that the correct option is D.
What is the equation?We know that the graph of F(x) has the same shape of G(x) = x^2, but shifted to the left 2 units.
Remember that for a random function f(x), a shift of 2 units to the left is written as:
h(x) = f(x + 2).
Then, in this case, we can write:
F(x) = G(x + 2)
Replacing G(x), we can get the transformed equation:
F(x) = G(x + 2) = (x + 2)^2
So we can se that the correct option is D.

The height of the boat floating above the seafloor at high tide is 17.5 feet.
In this question, we have been given a boat which is anchored in the water.
At low tide, the boat is floating 20 feet above the seafloor and is a horizontal distance of 40 feet away from its anchor.
And at high tide, the boat is a horizontal distance of 35 feet away from its anchor.
We need to find the distance the boat floating above the seafloor at high tide.
Consider the following diagram.
Let the boat floating m feet above the seafloor when the boat is a horizontal distance of 35 feet away from its anchor.
Since both the triangle are similar triangles, the corresponding sides must be in proportion.
⇒ 20/40 = m/35
We need to find the value of m.
⇒ 20 × 35 = m × 40
⇒ m = 35 / 2
⇒ m = 17.5 feet
Therefore, the height of the boat floating above the seafloor at high tide is 17.5 feet.

Durante un entrenamiento, un ciclista da una vuelta a una pista circular en 105 segundos, mientras que otro tarda 60 segundos. Si ambos inician sus recorridos juntos, ¿en cuántos segundos será la próxima vez que coincidan en el punto de inicio?
Los ciclistas se encuentran aproximadamente 140 segundos después de partir.
¿En cuanto tiempo se encuentran dos ciclistas que se mueve a distintas rapideces constantes por primera vez?
En este problema asumimos que cada ciclista se mueve a rapidez constante, de modo que la rapidez angular de cada uno se define como sigue:
ω = 2π / T (1)
Donde:
ω - Rapidez angular, en radianes por segundo.T - Período, en segundos.A su vez, la posición de cada ciclista es descrita por las siguientes dos ecuaciones paramétricas:
x / R = cos ωt (2)
y / R = sin ωt (3)
Donde:
x, y - Coordenadas del ciclista.R - Radio de la pista circular.Primero, determinar la rapidez angular de cada ciclista:
ω₁ = 2π / 105 s
ω₁ ≈ 0.060 rad / s
ω₂ = 2π / 60 s
ω₂ ≈ 0.105 rad / s
Segundo, procedemos a graficar cada función paramétrica y determinamos el primer punto de intersección. Los resultados se encuentran en las imágenes adjuntas. Nótese que las curvas verde y púrpura se basan en la ecuación (2), mientras las curvas azul y rojo lo son de la ecuación (3).
Los dos ciclistas se encuentran por primera vez si las cuatro ecuaciones tienen el mismo valor t. En consecuencia, los ciclistas se encuentran aproximadamente 140 segundos después de partir.

DE is parallel to ST as ∠ EAT = ∠ AED which are alternate interior angles.
∠TAC = ∠ABC (The angle between the chord and the tangent is equal to the angle in the alternate segment)
Since, EDCB is a cyclic quadrilateral,
∠CBD + ∠CED = 180 ----- I
- ∠CED + ∠AED = 180 -----II
----------------------------------------------------
∠ CBD = ∠AED
Also, ∠ CBD = ∠ EAT( A is tangent to the circle)
So, ∠ EAT = ∠ AED ( Alternate interior angle)
So, DE || ST
Therefore, DE is parallel to ST as ∠ EAT = ∠ AED which are alternate interior angles.

Astronauts brought back 500 lbs rock samples from the moon they brought back 227 kilograms of sample. The correct option is D.
Who, in brief, is an astronaut?
A space traveler is referred to as an astronaut. The term "astronaut" is currently used to designate to anyone traveling on a spaceship, including civilians, whereas it was previously reserved for military-trained experts.As the astronaut brought 550 lbs sample,
2.20lbs = 1 kg.
1 lbs = 1/2.20
1 lbs = 0.45
so, 500 lbs nearly implies 227kgs.
