Answer:
168 hours
8,736 hours
Step-by-step explanation:
1)
<em>Determine how many hours are equal to 1 week. </em>
1 week = 7 days
1 day = 24 hours
1 week * (7 days)/(1 week) * (24 hours)/(1 day) = 168 hours
2)
<em>How many hours are in a year (52 weeks)?</em>
1 week = 168 hours
1 year * (52 weeks)/(1 year) * (168 hours)/(1 week) = 8,736 hours
Answer:
10
Step-by-step explanation:
14 - (17 - 5) + 8
PEMDAS says parentheses first
14 - (12) + 8
Since we have no exponents, or multiplication or division
We add and subtract from left to right.
2+8
10
1.924 and 5.77
step 1: find the mean by adding up all the numbers and divide the sum by the number of numbers.
step 2: find the difference between each number and the mean, square the difference
step 3: add up all the results of step 2, divide the sum by (n-1), n is the number of numbers.
step 4: square root the result of step 3.
it is a long process.
