Answer:
The correct option is;
After 64 seconds, ABOUT HALF of the brands of milk chocolate ARE LIKELY to melt, and NONE of the brands of dark chocolate ARE LIKELY to melt
Step-by-step explanation:
Here we have for the milk chocolate
Min = 29 s
Lower quartile Q₁ = 44 s
Median = 64 s
Upper quartile Q₂ = 93 s
Max = 129 s
For the dark chocolate
Min = 210 s
Lower quartile Q₁ = 237 s
Median = 259 s
Upper quartile Q₂ = 295 s
Max = 320 s
As seen from the values of the box plot, after the median time of 64 seconds which represents half of the test results of the milk chocolate about half of the brands of milk chocolate are likely to melt, while the dark brands only start to melt after 210 seconds.
Therefore the correct option is
After 64 seconds, ABOUT HALF of the brands of milk chocolate ARE LIKELY to melt, and NONE of the brands of dark chocolate ARE LIKELY to melt.
Quadratic formula: x equals negative b plus or minus the square root of b squared minus 4 ac all over 2a
a=2 b=5 c=1
x=(-5+/5^2-4(2)(1))/2(2)
-5+/25-8/4
-5+/17/4
(-5+4.12)/4
-0.877/4
-0.219
x=(-5-/5^2-4(2)(1))/2(2)
-5-/25-8/4
-5-/17/4
(-5-4.12)/4
-9.12/4
-2.28
x=-0.219 or x=-2.28
Respuesta:
36
Explicación paso a paso:
Para completar el cuadrado tendremos que sumar la mitad del cuadrado del coeficiente de x a la expresión;
Coeficiente de x = -12
Mitad del coeficiente = (-12/2) = -6
Tomando el cuadrado del resultado = (-6) ^ 2 = 36
Por lo tanto, el número que se debe sumar para obtener un cuadrado perfecto es 36.

Answer:
right trapezoid
Step-by-step explanation:
It is a quadrilateral, but it's a special type called a right trapezoid (or trapezium, depending what country you are from).
The definition of a right trapezoid is a quadrilateral (4 sided shaped) with 2 parallel sides and 2 adjacent right angles.
