Answer:
<h2>(2)</h2>
Step-by-step explanation:
Because
not
This follows from the formula
Answer:
Yes we can conclude.
Step-by-step explanation:
The sampling distribution of can be approximated as a Normal Distribution only if:
np and nq are both equal to or greater than 10. i.e.
Both of these conditions must be met in order to approximate the sampling distribution of as Normal Distribution.
From the given data:
n = 50
p = 0.80
q = 1 - p = 1 - 0.80 = 0.20
np = 50(0.80) = 40
nq = 50(0.20) = 10
This means the conditions that np and nq must be equal to or greater than 10 is being satisfied. So, we can conclude that the sampling distribution of pˆ is approximately a normal distribution

Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = -2x + 9
y = 3x + 9
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 3x + 9 = -2x + 9
- [Addition Property of Equality] Add 2x on both sides: 5x + 9 = 9
- [Subtraction Property of Equality] Subtract 9 on both sides: 5x = 0
- [Division Property of Equality] Divide 5 on both sides: x = 0
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = -2x + 9
- Substitute in <em>x</em>: y = -2(0) + 9
- Multiply: y = 0 + 9
- Add: y = 9
I believe the answer is
1.1-(-3.8)=4.9
