Answer: The required probability is 
Step-by-step explanation:
Since we have given that
Number of spruce tree = 20
Number of maple tree = 50
Total trees = 70
We need to find the experimental probability that the next tree Colleen to get a spruce tree.
So, the probability would be :

Hence, the required probability is 
Answer:
<u>Recursive:</u>

<u>Explicit:</u>

Explanation:
<u>1. Sequence:</u>

<u>2. Recursive formula</u>
The recursive formula permits to calculate the value of the nth term in the sequence using the (n-1)th term in the sequence.

<u>3. Explicit formula</u>
The explicit formula permits to calculate any value of a term in the sequence:

Answer:
46
Step-by-step explanation:
By arranging the numbers from least to greatest, you can find the median by locating the central number in the data set.
So what you would need to add to get -6 is -5-1 then your answer would be -6 hope this helps!
Answer:
(21, 17 )
Step-by-step explanation:
Using the midpoint formula and equating to the coordinates of the midpoint.
Let endpoint 2 have coordinates (x, y ), then
0.5(x - 3) = 9 ( multiply both sides by 2 )
x - 3 = 18 ( add 3 to both sides )
x = 21
and
0.5(y - 5) = 6 ( multiply both sides by 2 )
y - 5 = 12 ( add 5 to both sides )
y = 17
endpoint 2 = (21, 17 )
