Answer:
The z-score of a beetle with a length of 2.38 centimeters is 2.4
Step-by-step explanation:
As we know,
z = (x - µ)/σ
x is the length of the beetle species.
µ is the mean length
σ is the standard deviation
Substituting the given values in above equation, we get
z = (2.38 - 1.9)/0.2
z = 0.48/0.2
z = 2.4
Answer:
y = 3/2x + 2
That is ur correct answer
Answer:
0%
Step-by-step explanation:
Don't quote me on that but I'm pretty sure
Slope = (y2-y1)/(x2-x1)
The points: (2,0) and (0,3)
(3-0)/(0-2) = 3/-2 = -3/2
The solution is -3/2

Answer: 4/25</h3>
=========================================================
Explanation:
Add up the first two frequencies to get 14+18 = 32
The table shows that the person rolled either a "1" or a "2" a total of 32 times, which is the amount of rolls getting less than "3".
This is out of the 200 rolls total.
32/200 = (8*4)/(8*25) = 4/25
In decimal form, this would be 4/25 = 0.16 which is exact.
