Answer:
1. 0.1635
2. 0.0026
Step-by-step explanation:
The computation of the probability in the following cases are as follows:
1.
Given that
Mean = 25 minutes
ANd, the standard deviation is 6.1 minutes
So here the z score would be
= (31 - 25) ÷(6.1)
= 0.98
Now the probability is
= P(Z>0.98)
= 0.1635
2. the z score would be
= (8 - 25) ÷(6.1)
= -2.79
Now the probability is
= P(Z<-2.79)
= 0.0026
X=3
y=1
Use substitution method starting with the first equation substitute y in the second equation
Answer
The Associative Property of Addition
Step-by-step explanation:
Because according to that property, you can group any two numbers and the answer will be the same.
A line with a slope=0 has the same values of "y"
if we have two points.
A(x₁,y₁)
B(x₂,y₂)
the line between these two points will be horizontal o slope=0 if : y₁=y₂
