Here, the given equation is,
x^2+y^2+px+6y-3=0
By copairing it with x^2+y^2+2gx+2fy+c=0, we get,
2g=p or, g=p/2
2f=6 or, f=3
c=-3
now the radius is,
r^2=g^2+f^2-c
or, 4^2=(p/2)^2 +3^2 -(-3)
or, 16= p^2/4 +9+3
or, 16-9-3=p^2/4
or p^2/4=4
or, p^2=4×4
or p^2=4^2
or p=4
therefore the rewuired value of p is 4.
A dozen eggs is 12 eggs.
Divide 1.12 by 12
1.12/12=0.93
Then multiply it by 3
.093*3=.28
3 eggs would cost you 28 cents.
Answer:
<u>n = 6</u>
Step-by-step explanation:
5(n + 4) = 50
5n + 20 = 50
5n = 30
n = 30/5
<u>n = 6</u>
Answer:
Step-by-step explanation:
The null hypothesis is described as the default hypothesis while the alternative hypothesis us always tested against this null ie the opposite of the null hypothesis.
In this case study, Let the proportion of houses that have home security be p
Thus, the null hypothesis is proportion of houses that have home security is 45% : p = 45%
The alternative hypothesis is proportion of houses that have home security is different than 45%: p =/ 45%
Answer:
3n-7=2n+5
Step-by-step explanation:
The equation is : 3n-7=2n+5
3n-2n=12
n=12
