Answer:
x= 8
x= -8
Step-by-step explanation:
|x+1| /3 = 3
|x+1| = 9
|x| + |1| = 9
|x| = 8
x= 8
x= -8
Answer:
angle 6 is 78 degrees
Step-by-step explanation:
Angle 3 and angle 6 are supplementary so they are the same angle.

The mean and standard deviation of the x sampling distribution for each of the following sample sizes will be
.
<h3>What is the distribution of the sample mean for large samples?</h3>
Suppose X has a distribution with mean
and standard deviation
then,
the distribution of the mean of samples of size n, drawn from the values of X, is normally distributed with a mean equal to the mean of X, and a standard deviation equal to 
Symbolically, we write it as:

A random sample is selected from a population with a mean = of 100 and a standard deviation = of 10.
The mean and standard deviation of the x sampling distribution for each of the following sample sizes.

Answer/Step-by-step explanation:
27.
✔️Sin 23 = opp/hyp
Sin 23 = t/34
34*sin 23 = t
t = 13.3
✔️Cos 23 = adj/hyp
Cos 23 = s/34
s = 34*cos 23
s = 31.3
28.
✔️Sin 36 = opp/hyp
Sin 36 = s/5
s = 5*sin 36
s = 2.9
✔️Cos 36 = adj/hyp
Cos 36 = r/5
r = 5*cos 36
r = 4.0
29.
✔️Sin 70 = opp/hyp
Sin 70 = w/10
w = 10*sin 70
w = 9.4
✔️Cos 70 = adj/hyp
Cos 70 = v/10
v = 10*cos 70
v = 3.4
