Write an inequality that represents the solutions on each number line

A number line scaled in ones from negative 4 to 4. The endpoint of a line graph starts with a closed circle on 1 and continues with an arrow in the positive direction.

When the inequality sign is < / > (less than/greater than), you use an open circle.

When the inequality sign is ≤ / ≥ (less than or equal to/greater than or equal to), you use a closed circle.

"The endpoint of a line graph starts with a closed circle on 1 and continues with an arrow in the positive direction."

(x represents the unknown number)

x ≥ 1    [x is any number greater than or equal to 1]

The reason why the inequality is x ≥ 1 is because there is a closed circle on 1 which means x can = 1, and the arrow is in the positive direction which means that the numbers are increasing and are greater than 1

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
