Answer:
Indeed, having 15 people recognize the brand would be considered unusual, as it lies beyond 2 standard deviations from the average.
Step-by-step explanation:
Examine the provided data.
The average recognition rate for the Yummy brand name among groups is 12.5, with a standard deviation of 0.58.
Mean = μ= 12.5
σ = 0.58
n = 15
![\mu\pm2\sigma=12.5\pm 2(0.58)\\\mu\pm2\sigma=12.5\pm1.16\\\mu\pm2\sigma=[11.34, 13.66]](https://tex.z-dn.net/?f=%5Cmu%5Cpm2%5Csigma%3D12.5%5Cpm%202%280.58%29%5C%5C%5Cmu%5Cpm2%5Csigma%3D12.5%5Cpm1.16%5C%5C%5Cmu%5Cpm2%5Csigma%3D%5B11.34%2C%2013.66%5D)
Thus, having 15 people recognize the brand would indeed be unusual, as it is outside of the 2 standard deviations from the mean.
To address this question effectively, it's essential to clarify the characteristics of the given geometric terms.
A quadrilateral is defined as a four-sided figure.
Parallelograms are a subset of quadrilaterals characterized by having two pairs of parallel sides, with congruent opposite sides and angles. Instances of parallelograms include squares, rectangles, and rhombuses.
Trapezoids are also categorized under quadrilaterals but are distinguished by having only one pair of parallel sides.
In our investigation, we seek to determine whether there exists a four-sided shape without parallel sides. The included image presents an example of a quadrilateral that does not qualify as either a parallelogram or a trapezoid. Therefore, in accordance with the definitions of these polygons, the correct choice is B.
Answer:
720 formas posibles
Explicación paso a paso:
La medalla de oro se otorga al primer lugar, la medalla de plata al segundo lugar y la medalla de bronce al tercero.
Cualquier corredor entre los 10 puede ocupar la primera posición.
La segunda posición puede ser ocupada por los 9 corredores restantes.
Mientras que la tercera posición puede ser ocupada por los 8 corredores que quedan.
Por lo tanto, el número de formas en que se pueden otorgar estas medallas es = 10 * 9 * 8 = 720 formas.
C(m) = (m + 4)^2 + 100 + (m + 12)^2 - 50 =
(m + 4)(m + 4) + 100 + (m + 12)(m + 12) - 50
m^2 + 8m + 16 + 100 + m^2 + 24m + 144 - 50
2m^2 + 32m + 210 <==
Response:
Detailed explanation:
The probability can be found by determining the z score,
(pˆD−pˆE) - (PD - PE)
0.0914
10.1917 - 0.1
0.0914 = 1.0029
P(z > 1.0029) = 1 - P(z ≤ 1.0029)
The probability is acquired using the z distribution table,
P(Z > 1.0029) = 1-0.8420 = 0.1580
