The equation that would let us determine the number of people or population at a certain year is calculated through the equation,
A(t) = A(o)(2^(t - 1950)/50)
Substituting the known values,
A(t) = (2.5 million people)(2^(2100 - 1950)/50))
A(t) = 20 million
<em>Answer: 20 million people</em>
The signs of the x-term and the constant term are both positive, so the signs of the constants in the binomial factors must be the same and must both be positive. The only offering that meets that requirement is
... C (2x+1)(3x+5)
_____
If you multiply that out, you get 6x² + 10x + 3x + 5 = 6x² +13x +5, as required.
The sign of the constant term is the product of the signs of the constants in the binomial factors: (+1)·(+5). We want a positive sign for the constant, so both binomial factor constants must have the same sign.
When the signs of the binomial factor constants are the same, the x-term constant will match them. Thus, for a positive x-term constant, both binomial factor constants must be positive.
Given that the two cone are similar, then
3/7 = x/5
7x = 15
x = 15/7
4.7 = 4 + 0.7
7/10
4 7/10
Answer: D)
Answer:
a
P(X \le 250 ) = 0.7564 [/tex] ,
,

b

c
Step-by-step explanation:
From the question we are told that
The value for 
The value for 
Generally the Weibull distribution function is mathematically represented as

Generally the probability that a specimen's lifetime is at most 250 is mathematically represented as




Generally the probability that a specimen's lifetime is less than 250

[texP(X < 250 ) =1 - e^{- (\frac{250}{220} )^{2.7}}[/tex]

Generally the probability that a specimen's lifetime is more than 300


[texP(X < 300) =1- [1 - e^{- (\frac{300}{220} )^{2.7}}][/tex]

Generally the probability that a specimen's lifetime is between 100 and 250 is
