Answer:
a. p`± z₀.₀₂₅
b.0.6 ± 1.96
c. { -1.96 ≤ p`± z₀.₀₂₅ ≥ 1.96} = 0.95
Step-by-step explanation:
Here the total number of trials is n= 1000
The number of successes is p` = 600/1000 = 0.6. The q` is 1 - p`= 1- 0.6 = 0.4
The degree of confidence is 95 % therefore z₀.₀₂₅ = 1.96 ( α/2 = 0.025)
a. The formula used will be
p`± z₀.₀₂₅ ( z with the base alpha by 2 (α/2 = 0.025))
b. Putting the values
0.6 ± 1.96
c. Confidence Interval in Interval Notation.
{ -1.96 ≤ p`± z₀.₀₂₅ ≥ 1.96} = 0.95
{ -z( base alpha by 2) ≤ p`± z₀.₀₂₅ ≥ z( base alpha by 2) } = 1- α
Answer:
B
Step-by-step explanation:
if you look at it, it increases up to -4, and then it also decreases at -4 because it's the same line. I'm really bad at explaining so I'm sorry if this doesn't make sense.
Answer:
12x+2
Step-by-step explanation:
-2(-6x-1) =
(-2*-6x) + (-2*-1) =
12x + 2
When we round to the nearest tenth, we need to look to the number in the hundredths place.
789.652
If the number is 4 or less, then we round down. If the number is 5 or more, then we round up.
Since '5' is 5 or more, we know to round up. So....
789.652 becomes 789.7
Answer=789.7
Answer:
-8n + 9
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
A = -3n + 2
B = 5n - 7
A - B
<u>Step 2: Simplify</u>
- Substitute: -3n + 2 - (5n - 7)
- Distribute negative: -3n + 2 - 5n + 7
- Combine like terms (n): -8n + 2 + 7
- Combine like terms (Z): -8n + 9
