Answer:
Approximately 19.4%
Step-by-step explanation:
Co. Dogs: 13
Co. Others: 54
13+54=Total Co.
=67.
Co. Dogs: 13/67.
App. 19.4% (For 13 Co.)
App. 1.49% (For 1 Co.)
An exponential function can be expressed as:
y=ab^x we have two points so we can solve
64/8=(ab^4)/(ab^1)
8=b^3
2=b, now we have:
y=a(2^x), using point (4,64)
64=a(2^4)
64=16a
4=a so
y=4(2^x)
All you do is divide -12/20 by 4/4 which is -3/5
Answer:
About 6 athletes.
Step-by-step explanation:
We are concerned only with the percent of athletes that are above one standard deviation.
Between one standard deviation and two standard deviations, there is 13.6% of the athletes.
From 2 to 3, there is 2.1%. Above 3, there is 0.2%.
The sum of those percentages is 15.9% of 40 = 0.159 · 40 = 6.36 or about 6 athletes.
Hope this helps.
