<h3>
Answer: 2/3</h3>
============================================================
Use the slope formula to get that answer
m = (y2-y1)/(x2-x1)
m = (5-1)/(9-3)
m = 4/6
m = 2/3
We have a rise of 2 and a run of 3.
In other words, we move up 2 and over to the right 3.
Answer:
The 95% confidence interval for the population mean is between 61.5 and 68.5.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 65 - 3.5 = 61.5
The upper end of the interval is the sample mean added to M. So it is 65 + 3.5 = 68.5
The 95% confidence interval for the population mean is between 61.5 and 68.5.

Beginning with an "If-then" statement ⇣
<em>If </em><em>2/5 = 30 </em><em>then</em><em> 1/5 = 15</em>
Now we have 1/5, let's make it 1 by multiplying x5.
<em>15 x 5 = </em><em>75</em>

I can't show my work but::::: <span>12.57 is the answer</span>
hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = -2 and b = 1 (Center at the A(-2,1))
r = AP......P( -4 , 1)
r² = (AP)²
r² = (4+2)² +(1-1)² = 36
an equation of the circle that satisfies the stated conditions.
Center at </span></span> A(-2,1), passing through P(-4, 1) is : (x+2)² +(y-1)² = 36
