Answer:
0.4216
Step-by-step explanation:
from the data given The estimate of the standard deviation of the sampling distribution of b,
( The slope of the sample regression line for the relationship )
= 0.4216 ( i.e. intersection of SE coef and water temperature )
Testing the effect of water temperature on the length of time sea otters can remain
Answer:
Step-by-step explanation:
here you go mate'
step 1
X / 2 + 1 > 3 equation
step 2
X / 2 + 1 > 3 simplify the equation
step 3
1/ 2 + 1 > 3 subtract the number at the front
1 / 2 + 1 (-1)> 3(-1)
step 4
1/2x>2 multiply
answer
x>4
Against the wind 100 m 15 sec = 6.67 mtrs / sec
With the wind 100 m 10 sec = 10 mtrs / sec
psa means plane velocity in still air
ws means wind speed
psa -ws = 6.67
psa + ws = 10
Adding both equations we get:
2 * psa = 16.67
psa = 8.34 meters per second
Since psa + ws = 10 and psa = 8.34 then wind speed = 1.66 meters per second
Answer:
im not sure but 36
Step-by-step explanation:
If she already has 12 signatures: 60 - 12 = 48
48/3 = 16
so, she and her friends need at least 16 signatures each.
p being person;
p 
16 (p has to be greater or equal than 16)
