Answer:
m(DE) = 90°
Step-by-step explanation:
Since both circles are equal, therefore, their radius would be equal too.
m<S = 180 - right angle (angles on a straight line)
m<S = 180 - 90 = 90°
m<R = m<S (congruent triangles)
m<R = 90°
m<R = m(DE) (central angle = intercepted arc based on the central angle theorem)
Substitute
90° = m(DE)
m(DE) = 90°

Pls give me the hole equation
Answers
Answer:
x = 2
y = -3
Step-by-step explanation:
2x + 2y = -2, then 2y = -2 - 2x
3x - 2y = 12, then 2y = 3x - 12
so:
-2 - 2x = 3x - 12
add 2x and 12 to each side of the equation:
5x = 10
divide both sides by 5:
x = 2
2y = 3(2) - 12
2y = -6
divide both sides by 2:
y = -3

Step-by-step explanation:
A t-test is a statistic test from which inferences can be drawn based on weather the difference in the means of two sample groups that could have particular common characteristics. The t-test is used for data sets that are normally distributed and the variance may be unknown
The t-test is used to test a proposed hypothesis (assumption) about a population
Therefore, based on the interest of the health worker to determine if omega-3 fish oil can help reduce cholesterol in adults by finding the difference in the means for the group taking omega-3 fish oil and the group not taking omega-3 fish oil, from which it can be determined if the difference in mean is statistically significant, is an example of a t-test

Una familia buscá una vivienda valorizado en 200000 mil soles. Para lo cual buscan su financiamiento atravesó de 3 bancos, las cuales proponen las condiciones que se muestran en la tabla
Answers
Answer:
Banco A o banco B
Step-by-step explanation:
Question:
La tabla obtenida de una pregunta similar en el sitio se presenta a continuación;
[tex]\left |\begin{array}{ccccc}Entidad \ bancaria&Cuota \ inicial&Tasa \ de \ interes \ anual &\mid &Tiempo \ anos \\Banco \ "A"&10\%&15\%&\mid&20\\Banco \ "B"&20\%&13\%&\mid &25\\Banco \ "C"&0\%&10\%&\mid&30\end{array}\right |[/tex]
¿Qué banco es el más conveniente para financiar la vivienda familiar?
Para el banco A, tenemos;
El pago inicial = 10/100 × 200,000 = 20,000
El interés = 180.000 × 15 × 20/100 = 540.000
Importe total, A = 540.000 + 20.000 = 560.000
Para el banco B, tenemos;
El pago inicial = 20/100 × 200,000 = 40,000
El interés = 160.000 × 13 × 25/100 = 520.000
Importe total, B = 520.000 + 40.000 = 560.000
Para el banco C, tenemos;
El pago inicial = 0/100 × 200,000 = 0
El interés = 200.000 × 10 × 30/100 = 600.000
Monto total, C = 600,000 + 00 = 600,000
Por lo tanto, la familia debe seleccionar el banco A o el banco B que tenga el monto total de reembolso más bajo

What is a linear equation?A Linear Equation is an equation of a line. An equation in which the highest power of the variable is always 1. An equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
For the given situation,
Total number of hits = 18
Doubles + triples = 18
Let x be the number of triples. Then
Number of doubles = 18-x
Number of bases for doubles = 2 bases
Number of bases for triples = 3
The equation for the above situation is
⇒ [tex]2(18-x)+3x=42\\[/tex]
⇒ [tex]36-2x+3x=42[/tex]
⇒ [tex]x=42-36[/tex]
⇒ [tex]x=6[/tex]
Hence we can conclude that the number of triples is 6.
