Answer:
x ≠ -5
Step-by-step explanation:
The easiest way is to factor the numerator.
x2 + 9x + 20 = (x + 4)(x + 5)
Then
(x2 + 9x + 20)/(x + 5) = (x + 4)(x + 5) / (x + 5) = x + 4,
with the restriction that x ≠ -5
Answer:
2.3
Step-by-step explanation:
Answer:
0.35
Step-by-step explanation:
we know that
The formula to use for uniform distribution is equal to
where,
b is the upper limit of the distribution which is 5 minutes in this case.
a is the lower limit of the distribution which is 0 minutes in this case.
x is the concerned value which is 1.75 minutes in this case.
substitute the given values
That means
The probability that a randomly selected passenger has a waiting time less than 1.75 minutes is 0.35
Answer:
7.89474% decrease
Step-by-step explanation:
Solution:
Calculate percentage change
from V1 = 38 to V2 = 35
(V2−V1)|V1|×100
=(35−38)|38|×100
=−338×100
=−0.0789474×100
=−7.89474%change
=7.89474%decrease
In order to find the slope intercept form of the given coordinates above (-6,-3)(-9,-2) then you need to use the point slope formula :y-y1=m(x-x1) .now allyou have to due is to label each of the given coordinates x1,y1 and x2 ,y2.This will help with the differentiation of the given coordinates.Once you have done this apply the info within the formula ,and you will get an answer of :y= -1/3x - 5 ,and of course your slope is -1/3 and the y-intercept is -5 .
