Answer:
7.5
Step-by-step explanation:
You have to divide the miles by the hours drived and then divide 60 per the miles per hour
The EER of a cooling system is the ratio of BTUs per hour to watts.
.. EER = (6000 BTU/h)/(500 W)
.. EER = 12
Well you would do 30÷7
so your awnser is 5 pills each
Answer:
E(Y) = 1.666667
Step-by-step explanation:
By E(Y), we mean the expected value of Y. This is given as:
E(Y) =
,
Where F is the frequency.
As given:
The sample space (S) = {T,T,H}
And has a probability of:
H = 1/3
T = 2/3.
Frequency:
H = 1
T = 2.
Thus,
E(Y) = 1*(1/3) + 2*(2/3)
E(Y) = 1.666667.
X = 90 degreees, so you take 47 and 90 add them together and you get 137 degrees. you need 180 to make a triangle, so you subtract 137 from 180. the answer for y is 43 degrees. hope that helps
