The correct answer is line q
Answer:
n = -45
Step-by-step explanation:
<u>Turn 2/3n into 2n/3:</u>
2n/3 + 4 = -26
<u>Subtract 4 from both sides:</u>
2n/3 + (4 - 4) = -26 - 4
<u>2n/3 = -30</u>
<u>Multiply 3 from both sides:</u>
2n = -30 * 3
2n = -90
<u>Divide 2 from both sides:</u>
<u>2n = -90</u>
2 = 2
n = -45
<span>You have to calculate z-scores for each of these values and then compare them with what is needed for the 80%tile on a Normal curve.
z = (value - mean)/(standard deviation) = (value-60.0)/0.5.
z= 1 has 84% of the values smaller.</span>
<span>0.01028806584 there you go, you can simplify it if you need to.</span>
