Hey there!
We have to multiply, the "a" becomes a "negative a" ; solve this fraction to understand this step
Like: (multiplication) -a = 1/8
Let's multiply by a negative one on each of your sides
a = -(1/8)
* 1. * 1
Solve this and that gives us our answer⬆️
We have "two solutions " in this problem, which 1/8 or -1/8
Answer: 1/8 or -1/8 (option A)
Good luck on your assignment and enjoy your day

Answer:
A)
Step-by-step explanation:
Since we are given the function, we can simply plug in the x as 9. So we get 50(0.952)9. Solving this, we get 450(.952) and this is about 428. SO our answer is a) about 428 feral cats.
Answer: f) None of the above
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 5.6ft
Standard deviation r = 1.0ft
Number of samples n = 27
Confidence interval = 90%
z(at 90% confidence) = 1.645
Substituting the values we have;
5.6+/-1.645(1.0/√27)
5.6+/-1.645(0.192)
5.6+/-0.317 ft
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
