What is the equation of the circle with center (16, - 12) and a radius of 5
eimsori [14]

Answer:

x^2+y^2-32x+24y+375=0

Step-by-step explanation:

Equation of circle with given centre (h,k) and radius=r is

(x-h)^2+(y-k)^2=r^2

Given centre are=(16, - 12) and radius= 5

So equation of circle=

(x-16)^2+(y- -12)^2=5^2

x^2-32x+256+y^2+24y+144=25

x^2+y^2-32x+24y+375=0

Answer:

Option a

Step-by-step explanation:

Given two normal distribution samples

I group has 106 as mean and 8.5 as std deviation with sample size = 60

II group has 121 as mean and 6.3 as std deviation with sample size =38

We find mean difference =-15

For margin of error finding, we have to find the combined std error for the difference

Variance of difference = Sum of variances

STd error for difference = 1.50

Hence for 99% margin of error =2.58(1.50)

= 3.87
