Answer:
70
Step-by-step explanation:
angles in a triangle= 180
79+35=110
180-110=70
Answer:
-32/35
Step-by-step explanation:
-4/5 *8/7 you have to flip the right fraction to multiply since you cant actually divide
hope this helps
You made a mistake with the probability
, which should be
in the last expression, so to be clear I will state the expression again.
So we want to solve the following:
Conditioned on this event, show that the probability that her paper is in drawer
, is given by:
(1)
and
(2) 
so we can say:
is the event that you search drawer
and find nothing,
is the event that you search drawer
and find the paper,
is the event that the paper is in drawer 
this gives us:


Solution to Part (1):
if
, then
,
this means that

as needed so part one is solved.
Solution to Part(2):
so we have now that if
=
, we get that:

remember that:

this implies that:

so we just need to combine the above relations to get:

as needed so part two is solved.
Answer:
11. 9hrs
12. 5hrs 35min
13. 3hrs 48 min
Step-by-step explanation:
Makes it a bit easier if you convert to 24 hr time.
11. 10 - 19 is 9hrs
12. 545-1120 is 11-5 20-45 -> 6hrs -25min -> 5hrs 35min
13. 1800 - 2148 is 21-18 48-00 -> 3hrs 48 min
The solution of inequality is C < -40
<em><u>Solution:</u></em>
Given that the inequality that is used to find the celsius temperature that are less than -40 fahrenheit
To find: solution of inequality
<em><u>Given inequality is:</u></em>

So we have to solve the above inequality for C

Add -32 on both sides

Multiply both the sides by 

Thus the solution of inequality is C < -40
