Answer:
2.
Step-by-step explanation:
To round off to the nearest whole number, we look at the tenth place value (the first digit after the decimal point.)
If it is a 0-4, we round the entire number down. If it is 5-9, we round the entire number up.
In this case, the tenth digit is 4. 4 is from the category 0-4, so we round 2.436 down to 2.
Answer:
1.
d. (-14) + (-8)
2.
a. (-14) + 8
Step-by-step explanation:
(-14) - 8 is equal to (-14) + (-8) because we still add two negative values so the result wouldn't change.
(-14) - (-8) is equal to (-14) + 8 because there's two negative sign in front of 8 and two negative values multiplied makes a positive result.
the answer is 1/8 because since one toss would be 1/2 then 1/2 * 1/2 *1/2= 1/8
