B. irrelevant evidence. a claim would be something that hasn’t been proven yet, so if it is accurate according to studies from the source, it just doesn’t matter
Answer:
confidence coefficient for 99% is 2.58
2.58 * 19.4/sqrt(n) = 0.04
2.598*19.4/0.04 = sqrt(n)
( 2.598*19.4/0.04)^2 = n
1587676
---------------------------------------------------------------------------
confidence coefficient for 90% is 1.64
(1.64*19.4/0.04)^2 = 632661.16
Answer:
<u>x = 7</u>
Explanation:
Because 25 is a perfect square of 5, we can turn
=
into
=
Since the bases are now both equal, we can completely ignore them, as we are only trying to find x. This leaves us with:
3x - 5 = 2x + 2
All we have to do now is solve for x:
x - 5 = 2 <em>Subtract 2x from both sides.</em>
<u>x = 7</u> <em>Add 5 to both sides.</em>
