Ok what are you confused on
Answer:
The answer is "(0.461 , 7.206)"
Step-by-step explanation:
In the given question some information is missing, that is data. so, the correct answer to this question can be defined as follows:
UnLogged:
Logged:
formula of std error:
Point differential estimation =
For 90 percent t= 1.860 Cl & 8 df
error of margin E =
Lower bound =mean difference -E=0.461
Upper bound = mean difference+ E=7.206
In the above 90% confidence interval were the population mean= (0.461 , 7.206)
R = 6x + 5y
x = 7, R = 18
Substitute them in: 18 = 6(7) + 5y
18 = 42 + 5y
-24 = 5y
y = -24/5
It’s already in its simplest form
Notice that:
7=16-9
2=9-7
5=7-2
the next term would be: 2-5=-3
so each term of the sequence is equal to its previous term, subtracted from the second previous term:
Also, in order to describe the formula, we need to express the 2 first terms, 1 is not enough.
The recursive formula is:
The pythagorean theorem states that the sum of two legs to the 2nd power is equivalent to the hypotenuse to the 2nd power () . Do note that the pythagorean theorem only works with right triangles.
