Answer:
And we can find this probability using the normal standard distribution table and we got:
And the percentage faster than 13.28 seconds would be 91.9%
Step-by-step explanation:
Let X the random variable that represent the runtimes of a population, and for this case we know the distribution for X is given by:
Where
and
We want to find this probability:
And we can use the z score formula given by:
Using this formula we have:
And we can find this probability using the normal standard distribution table and we got:
And the percentage faster than 13.28 seconds would be 91.9%
- X + 8 > 6
- X > 6 - 8
- X > - 2
X < 2
on a horizontal number line . numbers to the left are less than numbers to the right .. numbers to the right are less than numbers to the left
Answer:
Slope form of line y = 9
Step-by-step explanation:
m= 3
The y-intercept of the line that passes through the given point (0,9) is
9 = 3(0) + b
b= 9
The equation of the line that passes through the given point (0,9) is
y =mx +b
y = 0 +9
y=9
