It’s b and don’t open the link above they take you’re information
test grades: 75, 82, 88, 70
Average = Total sum of all numbers/number of item in the set
Total sum of all numbers = 75 + 82+ 88 + 70 = 315
number of item in the set = 4
Average = 315/4 = 78.75
Answer:
Domain: [-8. 4]
General Formulas and Concepts:
<u>Algebra</u><em><u> </u></em><u>I</u>
- Domain is the set of x-values that can be inputted into function f(x)
- Interval Notation
Step-by-step explanation:
From the graph, we can see that our x-values span from -8 to 4. Since both are closed dot, they are inclusive in the domain:
[-8. 4] or -8 ≤ x ≤ 4
Answer:
Yes
Step-by-step explanation:
Same side lengths and same 90 degrees angle
Answer:
x = 116º
Step-by-step explanation:
the sum of angles on the same side equals 180º so:
x + 64º = 180º subtract 64º from both sides
x = 116º
