I wanna say 6.93...but for sure i am wrong as the answer choices do not meet my guess.
According
to the empirical rule, if the data form a "bell-shaped" normal
distribution, approximately 99.7 percent of the observations will be contained
within 3 standard deviations around the mean.

To add, a bell curve is used to describe the mathematical concept called
normal distribution, sometimes referred to as Gaussian distribution. </span>
2/6 and it = 3/6 which simplified as 1/2
Answer:
A.) (x + 2) and (2x - 1)
Step-by-step explanation:
So from the video i just watch this is how its done
3 (2x^2 + 3x - 2) = 0
4 and -1 gives you 3 and you divide them by a which is 2
4/2 (2/1) and -1/2 then you write them from the bottom to top
(x + 2) and (2x - 1)
Answer:
B.) 20 (x + 5) (x - 5) = 0
Step-by-step explanation:
20 (x^2 - 25) = 0
20 (x + 5) (x - 5) = 0
EZ
Distance between two points =
√(3−−2)2+(3−3)2= √52+02= √25+0=
√25= 5
Distance between points (-2, 3) and (3, 3) is 5
