Answer:
PROBABILITY, P = 0.9999
Step-by-step explanation:
1) Going by the central limiting theorem:
z= (x⁻ - μ) /( б√n) Follows normal distribution with mean 0 and variance 1.
Where
x⁻= sample mean,
μ = population mean,
б = population standard deviation
n= sample size
The required probability is
P(z < 0.5/(0.4/√ 10)
=P(z < 3.95)
P = 0.9999
Thus, probability, P=0.9999
Answer:
1.244"
Step-by-step explanation:
The mean is given by dividing the sum of the given numbers by the frequency. In this case, the frequency is 5 since we're given 5 rainfall data. The sum of the respective rainfall is equivalent to 1.7"+2.2"+0.5"+0.72"+1.1"=6.22"
Now dividing the above sum by frequency yields mean as follows
Step-by-step explanation:

Answer:
f(-1)=3
Step-by-step explanation:
f(x)=x^2-6x+3x-1
f(x)=x^2-3x-1
f(-1)=(-1)^2-3(-1)-1
f(-1)=1+3-1
f(-1)=4-1
f(-1)=3
Answer:
108
Step-by-step explanation:
divide 9 by 2, you get 4.5. multiply that by 24 and you get your answer.
