Answer:
<h2>|-4.5| = 4.5</h2>
Step-by-step explanation:
|a| = a for a ≥ 0
|a| = -a for a < 0
therefore
|-4.5| = -(-4.5) = 4.5
Answer: 0.38
Step-by-step explanation:
Since the variable x is represented by a standard normal distribution, the probability of x > 0.3 will be calculated thus:
P(x > 0.3)
Then, we will use a standard normal table
P(z > 0.3)
= 1 - p(z < 0.3)
= 1 - 0.62
= 0.38
Therefore, p(x > 0.3) = 0.38
The probability of x > 0.3 is 0.38.
