Michael is using a number line to evaluate the expression –8 – 3. after locating –8 on the number line, which step could michael complete to evaluate the expression?

He have to move 3 unit in left hand direction of -8 on number line.

Step-by-step explanation:

The Given Expression is -8 - 3.

To evaluate the Expressions using number line following steps to be followed:

Step 1:  Locate the first number or term.

Step 2: to further proceed with next number some rules to be used.

              a). if next term is positive then move in right hand direction of  

                   previous term on number line.

              b). if next term is negative then move in left hand direction of

                   previous term on number line .

Step 3: Follow step 2 till last term.

Here michale already located -8 on number line. Now he have to move 3 unit in left hand direction of -8 on number line because next term is -3. (Number line attached)

the answer is d

step-by-step explanation:

85.560%

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
