Answer:
Negative Binomial
Step-by-step explanation:
The girl receives only 5% of mail which are addressed to her. Rest of 95% mails belong to other family members.
P (X) = 5%
P (X) = 95 / 5
P (X) = 19
The family receives 19 mails out of which only 5% will address the girl. The all other mails belong to the other family members.
Answer:
MN = 7 cm
Step-by-step explanation:
Well the volume we can separate into pieces
first the ABCDEFGH (? you know this cuboid)
which has a volume of
if you ask where does the 4 come from
it comes from LP = KB = YC and JY + YC =JC
so
this is because JY = MX
the other volume is of BCNPKLXY (hope you understand which one)
and the volume is
and the last one is KYXLMJ (the top "triangle")
the volume is
so now add them up
and has to equal 444
and finally we know that MN = MX + XN = 3+4 = 7
so here is our answer MN = 7 cm
a couple of notes
3. the units don't matter due to the fact that everything is in cm
4. see the picture below to get a better idea of which prism I am talking of
5. tell me if you have questions :D
1 thousand and 1 hundred means 1100.
In scientific notation, it's 1.1*10^3
Initially to make the problem a bit more manageable ignore the .25 hours and just solve for 7 hours.
If he runs 5.5 miles per hour this would be considered his rate. So you can multiply 5.5 miles by the 7 hours he ran. This will give you the distance he ran after 7 hours. But in the problem he runs for an extra quarter of an hour so how do we include this in our answer.
First, figure out the rate of how far he runs every quarter of an hour. To compute this take your original rate 5.5 mi/hr and divide it by 4 to get it in terms of quarters of an hour: 5.5/4 = 1.375 <--- add this to your previous answer to get the total distance he ran.
Answer:
x = 7
Step-by-step explanation:
First, move the variables and numbers to the opposite sides
-3x = 12 - 33
Then add and subtract
-3x = -21
Divide and multiply
-x = -7
x = 7
