It means approximately equal to.
I would say Median but thats from lowest to highest not highest to lowest so I'm not sure :/
Answer:
B
Step-by-step explanation:
Use distributive property:
5(2x - 3) = 5x - 10
10x - 15 = 5x - 10
Isolate the variable:
10x = 5x - 10 + 15
10x = 5x + 5
10x - 5x = 5
5x = 5
x = 1
Answer:
the probability that a sample of the 35 exams will have a mean score of 518 or more is <em> 0.934 </em>or<em> 93.4%</em>.
Step-by-step explanation:
This is s z-test because we have been given a sample that is large (greater than 30) and also a standard deviation. The z-test compares sample results and normal distributions. Therefore, the z-statistic is:
(520 - 518) / (180/√35)
= 0.0657
Therefore, the probability is:
P(X ≥ 0.0657) = 1 - P(X < 0.0657)
where
- X is the value to be standardised
Thus,
P(X ≥ 0.0657) = 1 - (520 - 518) / (180/√35)
= 1 - 0.0657
= 0.934
Therefore, the probability that a sample of the 35 exams will have a mean score of 518 or more is <em>0.934 or 93.4%</em>.
