Step One is to add up all the values
6.5+5+6+5.5+7+4+4.5+5+6+5.5+4+7.5+6+7+8+5+6+6.5+6.5+5 = 116.5
Step Two is to divide the result from step one by 20 (since there are 20 values added up)
116.5/20 = 5.825
The sample mean is 5.825
Answer:
3/10 cm²
Step-by-step explanation:
Multiply the two values to find the area.
3/8 · 4/5 = 3/10
Therefore, the area is 3/10 cm².
Answer:
y = 2sinx + 2
Step-by-step explanation:
∵ y = Asin(Bx - C) + D
∵ D is the vertically shift
∵ It moves 2 units up
∴ D = 2
∴ y = 2sinx + 2
