Answer:
Hello your question has some missing information below is the complete question
answer :
Step-by-step explanation:
Red car and Blue car take up 2 spaces each
Green cars take up 1 space
<u>lets determine the number of ways of filling up the parking spaces</u>
i) First lets assume the last space is filled by Green car then there will be space occupied hence there will be ( n - 1 ) spaces left to be filled in ways
ii) lets assume the last space is filled by either a Red car or a Blue car then there will be parking space occupied hence there will be
( n - 2 ) spaces left to be filled in ways
<u>Hence A closed formula for </u><u> </u>
where : a1 = 1 way , a2 = 3 ways
We can find roots by setting f(x) = 0 --> x^4 - x^3 - 13x^2 + x + 12 = 0.
Factoring f(x) to make things easier for us gives us (x - 1)(x + 1)(x - 4)(x + 3), which, equal to 0, gives us the ability to set each set of parentheses = 0.
x - 1 = 0 gives us x = 1.
x + 1 = 0 --> x = -1.
x - 4 = 0 --> x = 4.
x + 3 = 0 --> x = -3.
our roots are x = 1, -1, 4, and -3.
Answer:
$4.911 million or $6.481 million
Thus, we are 95% confident that the mean amount of all venture-capital investments in the high-tech industry is somewhere between $4.911 million and $6.481 million.
Step-by-step explanation:
Given that:
sample size n = 18
standard deviation σ = 1.70
confidence interval = 95%
Sample mean
5.696
The level of significance = 1 - C.I
= 1 - 0.95
= 0.05
The critical value of from the Z tables
The 95% C.I for the mean is;
= 5.696 ± 0.785372
= (5.696 - 0.785372 , 5.696 + 0.785372 )
= ( 4.910628 , 6.481372 )
≅ $4.911 million or $6.481 million.
Thus, we are 95% confident that the mean amount of all venture-capital investments in the high-tech industry is somewhere between $4.911 million and $6.481 million.
Answer:
A=16
Step-by-step explanation:
formula is 2l+2w=A
It would be y=4x-7. I hope this helped :)
