Step-by-step explanation:
Given
Required
Determine the sample space
To determine the sample space, we have to select a card number and write it alongside the marble colours.
i.e.
Solving (b): Outcomes that involves blue marble
First, we list them out
Number of occurrence is 4
Answer:
B. 2
Step-by-step explanation:
(4, 3) (7, 9) M = Slope
M = 
Slope formula
Using the slope formula, plot both x and y intercepts
Slope needs to be simplified into a whole number
The sum of 69,75,81,87,93,99 is 504.0.
The toy rocket hits the ground when h(t) = 0.
So, h(t) = 0 = -9t^2 + 81.
Solving the equation,
-9t^2 = -81
Dividing by -9
t^2 = 9
Taking the square root.
t = 3
The answer is 3 seconds.
