Consecutive numbers are 1 apart
they are
x,x+1,x+2,x+3,x+4
average is 21
(x+x+1+x+2+x+3+x+4)/5=21
(5x+10)/5=21
times both sides by 5
5x+10=105
minus 10 both sides
5x=95
divide both sides by 5
x=19
x+1=20
x+2=21
x+3=22
x+4=23
the smallest number is 19
Common factors -10/15 -9/15
Subtract -19/15
Your answer is -19/15
First, I would show all the outcomes possible. To determine the number of the total outcomes, you use the formula: rⁿ, where r is the number of outcomes in 1 flip, and n is the number of lips. Thus, 2³ = 8 outcomes. These outcomes are:
1. HHH
2. TTT
3. HHT
<em>4. HTT</em>
5. HTH
6. THH
<em>7. TTH</em>
<em>8. THT</em>
From the given outcomes, there are <em>3 outcomes</em> that has at least two tails. These are the ones in bold characters.
Answer:
It's -7
Step-by-step explanation:
G/L=1000*g/mL, since 1 mL = 1/1000 of a litre.
