There is 9 chocolate cookies, so the probability of choosing chocolate is 
. We then simplify to get 
, or 0.3.
Answer:
2975.978
Step-by-step explanation:
This is pretty easy, just keep the order going on.
Here is the CORRECT order:
2 Thousand(s)
9 Hundred(s)
7 Ten(s)
5 One(s)
decimal part because there is <em>th</em> after each type of number (ex. thousand<em>th)</em>
9 Tenth(s)
7 Hundredth(s)
8 Thousandth(s)
centre of the circle =Midpoint of the diameter
centre of the circle=
radius of the circle=
equation of the circle: (x+2)²+(y-3)² = 40
ie.. x²+4x+4+ y²- 6y+ 9=40
ie... x²+y²+4x-6y-27=0
this is the answer......
Answer:
x = -7
, y = 0
Step-by-step explanation:
Solve the following system:
{4 x + 5 y = -28 | (equation 1)
-4 x - 7 y = 28 | (equation 2)
Add equation 1 to equation 2:
{4 x + 5 y = -28 | (equation 1)
0 x - 2 y = 0 | (equation 2)
Divide equation 2 by 2:
{4 x + 5 y = -28 | (equation 1)
0 x - y = 0 | (equation 2)
Multiply equation 2 by -1:
{4 x + 5 y = -28 | (equation 1)
0 x+y = 0 | (equation 2)
Subtract 5 × (equation 2) from equation 1:
{4 x+0 y = -28 | (equation 1)
0 x+y = 0 | (equation 2)
Divide equation 1 by 4:
{x+0 y = -7 | (equation 1)
0 x+y = 0 | (equation 2)
Collect results:
Answer: {x = -7
, y = 0
