Well, first I'd start off by adding the hours. 10:30 Am + 1 hour = 11:30 AM.
11:30 Am + 1 hour = 12:30 PM. 12:30 + 1 hour = 1:30 PM. Then I would add the minutes. 3/4 of an hour is 3/4 of 60 minutes which is 45 mins. So, 1:30 PM + 45 minutes would be 2:15 PM.
Answer:
(E) 3(sq rt 2)
Step-by-step explanation:
the figure is a square so all four sides are equal and has 90 degree corners.
the diagonal has the value of 6 so:
6^2=s^2+s^2
36=2s^2
s^2=18 or sq rt 18 which would be 3(sq rt 2)
Answer: C) (-3, -1)
X = -3 and y= -1
If you apply these values in the inequalities
y < 2x + 1
-3 < -2 + 1
-3 < -1
Since -3 is less than -1 , the values hold true for the first equation
y > -x-5
-3 > -1 - 5
-3 > -6
Since -3 is greater than -6, it also holds true for the 2nd equation
You have to calculate the expected value of pulling any number of good batteries.
There are 3 bad batteries (B) and seven good batteries (G)
If you pull two batteries the possible number of good batteries you can get are 0, 1 and 2.
GB, BG, GG, and BB
two chances for getting 1, one chance for getting two, and one chance for getting zero.
In order to calculate the expected value you have to first calculate the values of all the possibilities.
(GB = 7/10 x 3/10) (BG = 3/10 x 7/10) (GG = 7/10 x 7/10) (BB = 3/10 x 3/10)
Then take these answers and multiply them by the number of good batteries they each contain and add. (GB is 1 good battery, GG is two, etc.)
1(.21) + 1(.21) + 2(.49) + 0(.09)
The result is 1.4
The expected value of good batteries is 1.4
