1/x + 1/a = 1/b

Multiply both sides by x, then a, then b

x(1 + 1/a) = x(1/b)
x • a • 2 = b • x • a

Divide by x, then a

b = 2

Anastasy [175]

Answer:

The answer to your question is: (8, -2)

Step-by-step explanation:

Data

A (9, -16)

L (7, 12)

Formula

Consider a uniform density curve defined from x = 0 to x = 8. What percent of observations fall between 1 and 5?
allsm [11]

Answer:  0.50, which is choice b

Explanation:

The interval 1 \le x \le 5 covers 5-1 = 4 units in the horizontal direction.

This is out of 8 units that span from x = 0 to x = 8 (we could say 8-0 = 8).

So we get the final result of 4/8 = 0.50

In other words, the interval from x = 1 to x = 5 covers exactly half of the interval from x = 0 to x = 8.
