Answer:
the second row is not a function! top row is a function
Step-by-step explanation:
because in order for it to be a function for every x there is exactly one y meaning there is no repeating x values! the second row had x = 5 twice, therefore they repeated x values meaning it's not a function
Answer:
(a) The confidence interval is: 0.0304 ≤ π ≤ 0.0830.
(b) Upper confidence bound = 0.0787
Step-by-step explanation:
(a) The confidence interval for p (proportion) can be calculated as


NOTE: π is the proportion ot the population, but it is unknown. It can be estimated as p.

For a 95% two-sided confidence interval, z=±1.96, so

The confidence interval is: 0.0304 ≤ π ≤ 0.0830.
(b) The confidence interval now has only an upper limit, so z is now 1.64.

The confidence interval is: -∞ ≤ π ≤ 0.0787.
Answer:
Step-by-step explanation:
P = $295
r =7%
t = 270 days = 270/365
Interest = Prt

= $ 15.28
Amount = 295 + 15.28
Amount = $310.28
Answer:
C
Step-by-step explanation:
It is provable about 180 ways, some of them quite elegant. There was a book published in the 1940s listing what they then knew. Others have been added since and it shows up in the oddest places which you can search out.
That is interesting but it does not answer your question.
A: Nothing is defined. This statement is a truth, but unproved. A is not the answer.
B: No term requires defining unless you don't know what a hypotenuse is, but that is a separate problem.
D: a postulate is a statement that is true that cannot be proven nor does it need to be. There aren't that many around in math. Euclid said "All right angles are congruent." True and not needing proof.
C: It is a theorem. This is a statement that may not be obvious and does require proof.
