Answer: The distance or d = 6.324555
For:
(X1, Y1) = (-1, -3)
(X2, Y2) = (1, 3)
Step-by-step explanation:
Distance Equation Solution: This picture of the work out problem will show you how you would work it out.
Let y = 0 to find the x-intercept(s).
0 = 45 − 4x
*Then subtract 45 from both sides*
-45 = -4x
*Next, DIVIDE both sides by -4*
-45
—— = x
-4
*NEXT, realize that TWO NEGATIVES MAKE A POSITIVE *
45. 4
——— = x {FLIP} x=——-
4. 45.
y-Intercept
Let x = 0 to find the y-intercept(s).
y = 45 −4(0)
NEXT, SIMPLIFY:
y=45

Let x be a random variable representing the price of a Congo-imported black diamond. Let the higher price be p. Then,
P(x < p) = P(x < (p - mean)/sd) = P(x < (p - 60,430)/21,958.08) = P(z < 2)
Therefore,
(p - 60,430)/21,958.08 = 2
p - 60,430 = 2 x 21,958.08 = 43,916.16
p = 34,916.16 + 60,430 = 104.346.16
Therefore, The required price is $104,346.16
