➷ Find the total number of marbles (this will be the denominator):
4 + 16 + 5 + 16 + 10 = 51
Probability of pulling out red marble:
4/51
Probability of pulling out a green marble:
10/51
Add these two probabilities together:
14/51 <== the answer

Answer:
Option D
Step-by-step explanation:
Rate of change of a linear function between two points
and
is given by,
Rate of change 'm' = 
From the given table,
Rate of change of the function between (-2, 6) and (-4, 9),
Rate of change 'm' = 
m = 
Initial value = y-intercept
Let the equation of the line passing through a point (h, k) is,
y - k = m(x - h)
If a point (-2, 6) is lying on the graph of the function,
y - 6 = 
y = 
y = 
Y-intercept of the function = 3
Therefore, initial value of the function = 3
Option D is the answer.
Answer:
2520ft
Step-by-step explanation:
Calculation for what is the scale of the model?
Let x will be the span length
Hence,
x= 4200 feet long/20 inches long
x=210
Thus:
1 inch = 210 ft
1 ft = 2520
=2520ft
Therefore the scale of the model will be 2520ft
