The probability that the selected ball is from the second box (with a probability of 0.2) and (which means multiplication in probability terms) brown (with a probability of 0.5 from same box, having equal number of brown and yellow balls) will be 0.1 ( meaning 0.5 × 0.2)
This is a rhombus and in any rhombus, the diagonals intersects in the middle and they are perpendicular:
So all 4 triangles are right triangles and the sides are the hypotenuses.
1st) Calculate the sides: hypotenuse² = 3² + 4² = 25, and hypotenuse = 5
The area of each right triangle is (4 x 3)/2 = 6 units²
And the area of the 4 right triangles = 4 x 6 = 24 init²
Find the mean for both:
Sierra: 2 + 11 + 12 + 13 + 15 = 53
53/5 =10.6
Median is the middle value = 12
Alek: 9 + 11 + 11 + 12 + 13 = 56
56/5 = 11.2
Median = 11
A: The medians do not equal the mean.
B: Sierra's are more spread out, ( no identical ages and a greater range ).
C: Sierra's mean is less than Alek.
D. Sierra has an outlier (2).
The answer would be B
17-6 x 10/2+ 12
17-60/2+12
17-30+12
17-18
= -1
because when you add 1768 and 978 it would equal $2746 so the total between the both is 2746 so your answer is 2746
