Answer:
Step-by-step explanation:
73
We have that
point B (-3,-2)
point C (0,2)
the distance between B and C is
d=√(y2-y1)²+(x2-x1)²--------> d= √(2+2)²+(0+3)²-------> d=√25
d=5 units
the answer is
<span>the length of segment BC is 5 units
using a graph tool
see the attached figure</span>
Step-by-step explanation:
1.
when 3 coins are flipped the following outcomes are possible
h = heads, t = tails
h h h
h h t
h t h
h t t
t h h
t h t
t t h
t t t
yes, there have to be 8 options, because we have 3 positions with 2 possible outcomes. that means
2×2×2 = 2³ = 8 possibilities.
2.
at least 2 tails means 2 or 3 t in the list item :
h t t
t h t
t t h
t t t
3.
so, 4 out of the 8 possible outcomes. the probability is then therefore
4/8 = 1/2 = 0.5
Answer: 4 hours
Step-by-step explanation:
4 Hours
Explanation:
Make h = hours
You add the $55 extra cost for the assistant
$125h + $55 = $555
Use additive inverse to isolate the term with the variable
$125h + $55 - $55 = $555 - $55
Use multiplicative inverse to isolate the variable
= 
Hours would be: 4 Hours.

Answer:40
Step-by-step explanation: 60 is the same as 60% so if you subtract 60 from 100 you get 40
