1) Add 9 to both sides
2) You get 15y<45
3) Divide by 15 on both sides
4) You get y<15
Remember that < is less than and > is greater than
Also note that when you divide by a negative number, you need to flip the inequality symbol.
Hey there!
Find out how many men there are by subtracting the number of woman by the total number of students
32-9= 23
23 students are men
To find the percent just simply multiply. *cross multiply
23/32 *100= 71.87
100*23= 2300
2300/32= 17.875
17.875 rounds to 17.9
71.9% are men
We will use the Sine Law:

b = 5.001
Answer:
D) 5.0
Answer:
Internal validity
Step-by-step explanation:
The internal validity here is weak
Internal validity describes the extent to which an evidence weighs the cause and effect claim. In this study, the internal validity that brought about failure in the new exam is mainly due to the environment where the exam was written and not the new exam itself.
So this validity is weak in claiming that the new exam is not a good substitute for the old exam.
Putting them in the same good environment might help the researchers to draw a better conclusion.
