Answer:
7.51 m
Step-by-step explanation:
The equation matches that required for finding the length of a pendulum that has a period of 5.5 seconds. We can solve for L to find the length.
The length of a pendulum with period 5.5 seconds is about 7.51 meters.

Answer:
Step-by-step explanation:
Note the f(0) = 9
and f(1) = 15
Since, f(x) = abˣ substituting for x, we get:
9 = f(0) = a . b⁰ = a
⇒ a = 9
Now, f(1) = 15
⇒ 15 = a . b¹
⇒ 15 = 9 . b
⇒ b =
Therefore,
Hence, the answer.
Answer:
7.5 more push-ups
Step-by-step explanation:
From the dot plot attached :
Last month mean :
Σfx/Σf
Σfx = [(10*2)+(15*2)+(25*3)+(35*1)] = 160
Σf = (2 + 2 + 3 + 1) = 8
Mean = 160 / 8 = 20
This month mean :
Σfx/Σf
Σfx = [(10*1)+(15*1)+(25*1)+(30*3)+(40*2)] = 220
Σf = (1 + 1 + 1 + 3 + 2) = 8
Mean = 220/8
Mean = 27.5
Difference in mean :
This month mean - Last month mean
27.5 - 20
= 7.5
