Yes, the table represents a function.
None of the independent (x) values are repeated and each one has a corresponding (y) value.
If you had a repeated (x) value in the table, it would not represent a function.
For question 40 the answer is B
You can't really make it easier to add, but since the (8+25) is in parentheses you should add that first
52 + 33
Then add straight away
52 + (8+25) = 85
Answer:
Marcus score is 13.7, the mean is 12.89, and the standard deviation is 1.95, so I’ll do ( 13.7 – 12.89)/ 1.95, Since Marcus' z-score is 0.415. The area to the left of the z-score is 65.9% so therefore Marcus did scored better than 65.9% of the students. So Marcus needs to score 98% better of all the other students in order for him to receive an actual certificate.
Step-by-step explanation:
700*6=4,200
<em>*4,200 as an estimate.</em>
---------------------------
6*(758)
=6(700+50+8)
=4,200+300+48
=4,200+348
=4,548
