6+6=12
9+9=18
9+9=18
12+18+18= 48cm
Bring the 13 over to read
13-12y-13=0
then move the 12y over do it becomes
13-13=12y
0=12y
y=0
Parallel means the lines will never touch. so look at the photo and find out why this is the answer.
here is you're answer:
BD, AC, FH
Answer:
Step-by-step explanation:
Express Courier Service has found that the delivery time for packages is normally distributed. So we use
z = (x - mean)/standard deviation
mean = 13
standard deviation = 2
x = time of delivery in hours
a) P(0 lesser than/equal to 18)
z = (18-13)/2 =5/2 = 2.5
Using the normal distribution table, the value is 0.9938
b) to be 95% sure, let the time be t
From the table, the equivalent of z that is 0.95 = 1.645
So 1.645 = (t-13)/2
t-13 = 3.29
t = 3.29+13= 16.29 hours
Answer:
The deep of the water would be 20 cm
Step-by-step explanation:
step 1
Find the volume of the water
The volume of the water is equal to
we have
substitute
step 2
Find the deep of the water, if the tank is returned to its horizontal position
(resting on its 60 cm × 100 cm base)
Now we have
substitute the given values
solve for H
therefore
The deep of the water would be 20 cm
