Answer:
Right-skewed
Step-by-step explanation:
The shape of the weight distributed is skewed, because the mean and the median are not equal.
Moreover, the distribution is right-skewed because the mean is greater than the median and because the mean is influenced by the tail of large values.
Answer:
x = 2
Step-by-step explanation:
Probability that the marble comes to rest in the shaded region is equal to the ratio of the shaded area to the total area.
Probability 'P' =
Area of the shaded region (A')= (x + 1)(x + 2)
Total area of the figure (A) = (2x + 1)(3x + 2)
P =
10(x + 1)(x + 2) = 3(2x + 1)(3x + 2)
10(x² + 3x + 2) = 3(6x² + 7x + 2)
10x² + 30x + 20 = 18x² + 21x + 6
(18x² - 10x²) + (21x - 30x) + (6 - 20) = 0
8x² - 9x - 14 = 0
x =
x =
x =
x = -
Therefore, positive value of x = 2 will be the answer.
