What grade is this ???????????
Answer:
1.98
Step-by-step explanation:
Use SOH-CAH-TOA:
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Here, we're given the hypotenuse is 4.5, and we want to find the side opposite of the 26° angle. So we should use sine.
sin 26° = x / 4.5
0.44 = x / 4.5
x = 1.98

Step-by-step explanation:
Hello!
You have one population: Students at ABC University
One study variable: X: College a student is enrolled in, categorized: Bussiness College "B", Liberal Arts College "A" and Education College "E".
The objective of this study is to test if the proportions of students enrolled in each college are different from the known data.
