Answer:
14.7%
Step-by-step explanation:
Being that there is 4 red, 2 blue, 6 green, 8 white, that means there is 20 marbles, with 8 success, 8/20. Since the marble is not replaced, that drops it to 7/19 for the second pull. Multiply these together and you get 14.7%.
(8/20)*(7/19)=.147
.147*100=14.7
Volume of Pyramid with Square Base =
..... Area of Base × (Height/3)
1. Calculate length of side
Perimeter of Square: 4S
4S=36
S = 9
2. Calculate Area of Square: S^2
9^2 = 81
3. Calculate Volume: Area of Base × (Height/3)
81(9/3)
81(3)
243
Volume is C. 243 cm^2
In order to find the slope, you have to use the formula : Δy/Δx.
Here : Δy = -1 and Δx = 2.
Therefore, the slope would be : B. -1/2.
Hope this helps !

The average is 130 parts per hour.
Step-by-step explanation:
Given,
Parts being made at factory = 521
521 parts are made in = 4 hours
Average parts per hour =
Average parts per hour =
Average parts per hour = 130.25 parts
Rounding off to nearest whole number
Average parts per hour = 130 parts
The average is 130 parts per hour.
