Hello,
x²+y²-10x+6y+18=0
==>(x²-2*5x+25)+(y²+2*3y+9)+18-25-9=0
==>(x-5)²+(y+3)²=16
Radius is 4.
Center (5,-3)
18 times 10= 180
That is usually what it means
.3997 + 0.5 = 89.97%
Use your z table to get the area under the curve from 50 to 59. 50 is 1.28 std deviations from the mean. Then add the other 50%
Answer:
9 puppies
Step-by-step explanation:
15% = 9 puppies
30% = 18 dogs
75% = 45 dogs
100% = 60 dogs
1) To solve for x, is to leave the x on the left side the other variables on the right along with the constants, like this

Note that, we subtracted 5 and then divided by x.
