Answer:
n= 69 degrees
Step-by-step explanation:
total inside measure of any triangle is 180 degrees
180= n+n+42
180= 2n+ 42
2n= 180-42
2n= 138
n=69

Answer:
y = -4/5x + 4
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define</u>
Standard Form: 4x + 5y = 20
<u>Step 2: Rewrite</u>
- Subtract 4x on both sides: 5y = 20 - 4x
- Divide 5 on both sides: y = 4 - 4/5x
- Rearrange: y = -4/5x + 4
Answer:
His 95% confidence interval is (0.065, 0.155).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
His 95% confidence interval is (0.065, 0.155).
