First, I would create a number line that includes the number -4 to 4, with 1/4 notches (3 notches between each number).
For 3, I would count 3 numbers to the right from zero.
For 2.25, I would count 2 numbers from zero, plus one additional notch to the right. Remember that each notch represents 1/4, or 0.25.
For the opposite of 4, I would count 4 to the left to -4. The opposite of 4 is -4.
For -(-1 1/2), I would remember that this number is actually 1 1/2, since a negative times a negative number is positive. I would count one number to the right of zero, plus two notches.
Answer:
36
Step-by-step explanation:
since a fair die has 6 sides (i.e 6 possible outcomes),
P (rolls a 4 on 1 roll) = 1/6
hence if he rolls the die 216 times, we would expect to roll a 4 for 1/6 of the time. I.e.
expected number of times to roll a 4
= (1/6) x 216 = 36 times.
Answer:
359 + r = 212
Step-by-step explanation:
"359 and r more" suggests that you are adding the number 359 with the variable r. r + 359
"equals 212" is "= 212"
Put the two together:
359 + r = 212 is your answer.
