The probability for the z-score is greater than or equal to 1.4 is 0.08076 or 8.076 %.
<h3>What is a z-score?</h3>
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The probability for the z-score is greater than or equal to 1.4 is given as
P(z ≥ 1.4) = 1 - P( z < 1.4}
P(z ≥ 1.4) = 1 - 0.91924
P(z ≥ 1.4) = 0.08076
P(z ≥ 1.4) = 8.076 %

Answer:
c
Step-by-step explanation:
a: 9/5 and 19/10 are already in simplest form
b:25/35 can be simplified to 5/7 if you divide each side by 5 and 20/24 can
be simplified to 5/6 if you divide each side by 4
c: both 15/10 and 21/14 can be simplified to 3/2
d: 4/6=2/3 and 10/16=5/8
First group the coefficients together on their side of the equal sign.
-x + 3x = 2x.
Then, since it is a positive number, subtract it from that side and the other side.
On the other side, the x becomes -x.
Add the 6 from the other side to the 8 to make 14.
14 = -x
Divide both sides by -1, to get the answer.
x = -14
It took me awhile, but using the Rational Root Theorem and then synthetic division I got the first root. If you don't know the RRT you'll be in heaps of trouble doing this type of problem. I found the first root to be (x+6), then I did it again and got another root of (x+6) and the third one was (x-5). So the roots of this polynomial (and there are 3 because this is a 3rd degree polynomial) are (x+6) with a multiplicity of 2, and (x-5).
Answer:
8 ft.
Step-by-step explanation:
The formula for area of a square is:
We are given the area of 64 square feet.
Each side should be 8 ft.
Hope this helps.
