Answer:
0.4
Step-by-step explanation:
1.6 - 1.2 = 0.4
The answer is 19y – 9.
First, distribute the -3 to ( -4y + 3 ). So:
= ( 12y – 9 ) + 7y
Then, combine like terms. In this case, the like terms are 12y and 7y. So:
= 12y – 9 + 7y
= 19y – 9
<span>The number of cell phone minutes used by high school seniors follows a normal distribution with a mean of 500 and a standard deviation of 50. what is the probability that a student uses more than 580 minutes?
Given
μ=500
σ=50
X=580
P(x<X)=Z((580-500)/50)=Z(1.6)=0.9452
=>
P(x>X)=1-P(x<X)=1-0.9452=0.0548=5.48%
