Answer:
180 the answer. English is a West Germanic language first spoken in early medieval England which eventually became the leading language of international discourse in today's world.
Answer:

Step-by-step explanation:
If you are asking for the Greatest Common Factor [GCF], then here you go. All coefficients are divisible by 9...:
63: 1, 7, 9, 63
27: 1, 3, 9, 27
18: 1, 2, 3, 6, 9, 18
...and you take the LEAST DEGREE TERM POSSIBLE.
I am joyous to assist you anytime.
x^2 + y^2 + 2x - 6y + 1 = 0
x^2 +2x + 1 + y^2 - 6y = 0
x^2 + 2( x × 1) + 1^2 + y^2 - 2(y×3) + 3^2 -3^2 =0
(x+1)^2 + (y-3)^2 = 3^2
comparing with circle equation
(x-a)^2 + (y - b)^2 = r^2
where (a , b) is centre of circle.
so we get center of circle is
(-1, 3)
Answer:

If we compare this value with the 47.3 proposed we have the following error

The computed mean is close to the actual mean because the difference between the means is less than 5%.
Step-by-step explanation:
Assuming the following dataset:
Speed 42-45 46-49 50-53 54-57 58-61
Freq. 21 15 6 4 2
And we are interested in find the mean, since we have grouped data the formula for the mean is given by:

And is useful construct a table like this one:
Speed Freq Midpoint Freq*Midpoint
42-45 21 43.5 913.5
46-49 15 47.5 712.5
50-53 6 51.5 309
54-57 4 55.5 222
58-61 2 59.5 119
Total 48 2276
And the mean is given by:

If we compare this value with the 47.3 proposed we have the following error

The computed mean is close to the actual mean because the difference between the means is less than 5%.
7+ 3x= -8
-8-7=-15
-15 divided by 3= -5
-5 is the answer
