Answer:
X=2, AB=14, DC=14
Step-by-step explanation:
3x+8=x+12
Subtract x from both sides
2x+8=12
Subtract 8 from both sides
2x=4
Divide by 2 on the sides
Answer: x=2
Then replace the x's with (2) and multiply
3(2)+8 and (2)+12
The formula to calculate standard deviation from probability is \sqrt(n*p*(1-p)). n is the sample size, and 200 in this case (number of putts for practice). p is 80% or 0.8, the probability that he can make it. So the standard deviation is \sqrt(200*0.8*(1-0.8)=\sqrt(200*0.8*0.2)=\sqrt(16)=4.
(1-52/2+5)=(1-26+5)=(-25+5)=-20
continuing:
-20*2*6*6= -40*6*6=-240*6=-1440
result: -1440
Answer:
Step-by-step explanation:
To solve for x, we need to isolate the x variable.
Given:
Subtract 
from both sides of the equation:
Now, we will create common denominators to simplify.
Answer:
O.5
Step-by-step explanation:
Principal (P): $900.00
Time. (T) :3 years
Interest. (l ) :$54
Rate. (R): ?
R= P × T
100 × l
R= $900.00 × 3years
100 × $54
R= $9.00 × 3years
$54
R= $27
$54
R= 0.5
Therefore annual interest rate is 0.5
