Answer:
Step-by-step explanation:
116f) 5 - |p + 6| = -8
|p + 6| = 13
p + 6 = 13 OR p + 6 = -13
p = 7 OR p = -19
In this case, I think you have to plot a point at 7 and -19.
116a) |7x| = 5
7x = 5 OR 7x = -5
x = 
OR x = 
Again, I think you need to plot points at and .
To solve for the confidence interval for the true average
percentage elongation, we use the z statistic. The formula for confidence
interval is given as:
Confidence interval = x ± z σ / sqrt (n)
where,
x = the sample mean = 8.63
σ = sample standard deviation = 0.79
n = number of samples = 56
From the standard distribution tables, the value of z at
95% confidence interval is:
z = 1.96
Therefore substituting the known values into the
equation:
Confidence interval = 8.63 ± (1.96) (0.79) / sqrt (56)
Confidence interval = 8.63 ± 0.207
Confidence interval = 8.42, 8.84

Answer:
8/3=2/0.75
Step-by-step explanation:
The variable that you are looking for should be the simplified version of the number on the left.
That is where the 2 would come in. Both numbers should be divided by 4 to gat the answer.
8÷4 = 2
3÷4=0.75
The pattern is multiply by 5
2 x 5 = 10
10 x 5 = 50
50 x 5 = 250
250 x 5 = 1250
Answer
The next two terms: 250 and 1250
2, 10, 50,250, 1250
