Hmm, not sure
let me solve to make sure
so the lateral area=4*8+6*8+?*8
the ? is the hyptoonuse
remember
a^2+b^2=c^2
4^2+6^2=c^2
16+36=c^2
52=c^2
sqrt both sides
2√13=c
so
LA=4*8+6*8+8*2√13=
32+48+16√13=
80+16√13
the first blank is 80
2nd is 26
3rd is 13
Answer:
0.8 Miles per minute. 1.6 miles in 2 minutes
Step-by-step explanation:
It says 48 miles for 60 minutes. But we only want one minute, so we can divide 60 to get 1 and divide 48 by 60 to get 0.8 for 1 minute.
For the second question you want 2 munutes so you multily this rate by 2 (0.8*2) to get 1.6 miles.
Hope this helps
:)
Answer:
Step-by-step explanation:
Given
close
fail to close
First, calculate the value of q
Using complement rule
So, we have:
and
Solving (a): Fails to close on the 4th attempt
This means that he closes the first three attempts. The event is represented as: p p p q
So, we have:
Solving (b): He closes for the first time on the 3rd attempt
This means that he fails to close the first two attempts. The event is represented as: q q p
So, we have:
Solving (c): First he closes is his 2nd attempt
This means that he fails to close the first. The event is represented as: q p
So, we have:
Solving (d): The first he close is one of his 3 attempts
To do this, we make use of complement rule
The event that he does not close any of his first three attempts is: q q q
The probability is:
The opposite is that the first he closes is one of the first three
So, we have:
--- complement rule
