Answer:
4,5,8,11 are domain
Step-by-step explanation:
Since they are on the x side they are domain
Take the coordinates
Ex.
(-5,-1) and count it on the chart
The first number is your x value and ur second number is ur y
Y= up and down
X= side to side
Answer:
12^5
Step-by-step explanation:
12^5 means 12*12*12*12*12 (5 twelves)
Answer and Step-by-step explanation:
a)
expected value for the difference in sample means=3.5-3.2=0.3
b)
standard deviation of the sampling distribution of the difference in sample means
=sqrt((0.5^2/40)+(0.8^2/40))
=0.1492
c)
z=(0.3-0)/0.1492
z=2.01
P(z>2.01)=0.0222
D over dx (x sin^2(x)) = sin(x) (sin(x) + 2 x cos(x))
