Answer:
1/2
Step-by-step explanation:
=[-1/4 + 1/6] ÷ [1/3 - 1/2]
=[-3/12 + 2/12] ÷ [2/6 - 3/6]
=[-1/12] ÷ [-1/6]
=[-1/12] x [-6/1]
= 1/2
X/4 - 4 =18
This is the correct equation and if you solve it it X=88

Answer:
84%
Step-by-step explanation:
The empirical rule tells you that 68% of the standard normal distribution is within 1 standard deviation of the mean. The distribution is symmetrical, so the amount in the lower tail is (1 -68%)/2 = 16%.
Since the number you're interested in, 240, is one standard deviation above the mean (200 +40), the percentage of interest is the sum of the area of the central part of the distribution along with the lower tail:
68% + 16% = 84%.
