To find the margin of error, multiply the z-score by the standard deviation, then divide by the square root of the sample size.The z*-score for a 90% confidence level is 1.645.The margin of error is 0.20.The confidence interval is 48.3 to 48.7.48.8 is not within the confidence interval.
Answer:
the answere for this question is (b) because it has equal differences
Answer:
I think the third one
Step-by-step explanation:
Because
1st one: 24:1
2nd one: 50:1
3rd one: $9+$12
4th one: 10:1
Answer:
x + 4y = 20
Step-by-step explanation:
Step 1: Subtract "x" on both sides.
x + 4y = 20
<u>-x -x</u>
Step 2: Simplify --> 4y = -x +20
Step 3: Divide 4 on all sides to leave "y" by itself. 4y = -(1)x + 20
4 4 4
Step 4: Simplify: y = -1/4x + 5
Answr: The Slope is "-1/4". The slope will always be the number in front of the "x".
Answer:
1. multiply 4x4 (which equals 16)
2. add that answer to 3 (which equals 19)
Step-by-step explanation:
Use PEMDAS (Solve in parentheses first, then exponents, multiplication, division, addition, and subtraction in that order) for the correct order of operations
