It's C or A
Step-by-step explanation
this is because of the Commutative Property.
Let's solve it step by step:
(we start with the innermost bracket: (25/5). This is equal to 5. :
25+{2[3+8-7(25/5)+11]} =
25+{2[3+8-7(5)+11]} =
now, we can multiply 7 and 5, which is 35
25+{2[3+8-35+11]} =
Now we can add all the numbers in the square bracket, 3,8 (that's 11), then -35 (which is -24) then 11 - all together it's -13
3+8-35+11=22-35=-13
25+{2[-13]} =
Multiplying 2 and -13
25+{-26} =25-26, which is -1
the final answer is -1
What we know:
Lot= 21 x 30ft
Perimeter=2l+2w
Want to put 4 corner post and one post every 3 ft
What we need to find:
How many post we need.
Perimeter=2 (21)+2 (30)=42+60=102ft
102/3=34
34 posts are needed.
Answer:
they give us a sense of where a score falls in relation to the mean of its population (in terms of standard deviation of its population), 2) they allow us to compare scores from different distributions, and 3) they can be transformed into percentiles.
