Answer:
1. y-(is that a 7 or a 1?) = 2(x-4)
2. y-4 = (1/2)(x-2)
3. y = (2/3)(x+6)
... and so on
The formula for a line given point and slope is :
y - (y-value of point) = slope * x - (x-value of point)
To find the circumference of a circle, you can use the formula
πd, where d is the diameter of the circle.
In this instance, we can tell from the picture that the diameter of the circle is 16 inches.
Therefore, the exact circumference of the circle is
C. 16pi inches

Answer:
Step-by-step explanation:
Given that there are 20 non ionized containers and 73 ionized containers
Two samples are drawn without replacement
a) the probability that the first one selected is not ionized=
b) the probability that the second one selected is not ionized given that the first one was ionized
= When first one was ionized we got left over as 20 and 72
Hence = 
c) If with replacement left over 20 and 73 and hence prob = 0.215 as in part a
d) the probability that both are ionized=
