Answer:

157.5

Step-by-step explanation:

The first step is to find the area of the triangular base. The formula for the area of a triangle is bh/2, or in this case 5×7/2=17.5. Multiplying this by the length of the prism, you get 9×17.5=157.5. Hope this helps!

Answer: 157.5

Step-by-step explanation: To get the volume of an object you must multiply the width x height ÷ it by 2 x length

Therefore 7 x 5 = 35 ÷ 2 = 17.5

17.5 x 9 = 157.5

Determine whether the data distribution appears to be positively skewed, negatively skewed, or symmetric.
Licemer1 [7]

Answer:

Negatively skewed

Step-by-step explanation:

Arrange this data in ascending order:

46, 50, 57, 58, 59, 59, 65, 66, 77, 80

and draw the bar chart as shown in attached diagram.

The data distribution appears to be negatively skewed (or left skewed), because the scores fall toward the higher side of the scale and there are very few low scores. The mean is also to the left of the peak.

SVETLANKA909090 [29]
This is a Poisson Distribution
Average over 3 months = 2
Average over 1 month = 2/3
Average over 2 months = 4/3 = λ
More than four heavy rainfalls means 5, 6, 7,…
P(5) = (e^-λ x λ^5)/5! = 0.009257
P(6) = 0.002057
P(7) = 0.000392
P(8) = 0.000065
P(9) = 0.000010
P(10) = 0.000001
P(more than 4 heavy storms) = 0.01178 (4sf)
