Answer:
A) 53
B) 53%
C) 37%
D) 63%
E) Yes.
Step-by-step explanation:
A) 53 people did not get headaches at all.
B) To solve for the percentage of participants that reported they did not get a migraine headache, you will need to divide out of the TOTAL number of people:
53/100= .53 --> Convert to percentage--> .53×100 = 53%.
C) To find this value, you will need to divide out of the amount of people that took MEDICINE and got a headache:
22/60≈0.367--> Convert to percentage --> 0.367×100≈37%
D) This percentage will be found out of who did NOT take the medicine:
25/40= 0.625 --> Convert to percentage --> 0.625×100≈63%
E) The medicine did help prevent migraine headaches because the percentage that got <u>migraines with the medicine is lower</u> than the percentage that got <u>migraines WITHOUT the medicine.</u>
Answer:
A
Step-by-step explanation:
From the diagram:
- P(-4,6)→P'(4,6);
- Q(-7,4)→Q'(7,4);
- R(-6,1)→R'(6,1);
- S(-2,1)→S'(2,1);
- T(-1,4)→T'(1,4).
The general rule of this reflection is
(x,y)→(-x,y)
and this is reflection across the y-axis. The y-axis has the equation x=0.
Answer:
Yes
Step-by-step explanation:
Yes, because no matter how many 0's are after the decimal, the number stays the same.
It is a rational number and it equals 0.5 or 1/2
