Here
X1=-1, y1=4
X2=1, y2=-1
We have d=under root (x2-x1)sq+y2-y1)sq
=(1-(-1)sq + (-1-4)
=2sq+-5sq
=4+25
=29ans
Product A is 17 cents per oz.
Product B is 20 cents per oz.
Z(x)=(x- mean) / standard deviation
Z(18)=(18-26)/4=-2
Answer: x = 1
Step-by-step explanation:
we have
x tetras
3 goldfish
5 platies.
the total number of fishh in the bowl is x + 3 + 5
The probability of removing a gold fish is equal to the number of gold fish divided by the total number of fish, this is:
p = 3/(x + 3 + 5) = 1/3
3 = (1/3)(x + 3 + 5) = x/3 + 1 + 5/3
9 = x + 3 + 5
x = 9 - 8 = 1
then wemust have that x = 1
because 1 + 3 + 5 = 9
and 3/9 = 1/3
