The number of bats are expected to be in the colony after 11 years if the colony continues to grow at the same rate is 69,632
<h3>Exponential function</h3>
Let
- Number of bat at a time = n(t)
exponential function;
y = ax^t
When t = 3
272 = ax³
when t = 5
1088 = ax^5
272/1088 = ax^3 / ax^5
1/4 = x^3-5
1/4 = x^-3
1/4 = 1/x²
1 × x² = 4 × 1
x² = 4
x = 2
Substitute x = 2 into
272 = ax³
272 = a × 2³
272 = a × 8
272 = 8a
a = 272/8
a = 34
Number of bat expected at the colony after 11 years
y = ax^t
= 34 × 2^11
= 34 × 2048
y = 69,632 bats

Answer:
Step-by-step explanation:
A.fill the box as follows.
tally (remember to cross every 5)
20-29- IIIII
30-39-IIIIIII
40-49-IIIIIIIIIIIIIIIII
50-59-I
frequency-
20-29- 5
30-39- 7
40-49- 17
50-59- 1
B.Most common group is 40-49
C. range= 53-20=23 so it is 23.
Your answer is P= -8. Hope this helps.
