Her statement does not make sense. Here is why.First of all 8 x 10 = 80 so that would proove that 8 is a factor of 80.
Second of all just because a number doesn't end in zero doesn't mean it's not a factor of a number!
Hope this helped - Ashlynn
Answer:the answer is c
Step-by-step explanation:
Percent of turn pike is 75% and percent of parkway is 25%.
<u>Solution:</u>
Given, The state of New Jersey makes approximately $1.55 billion annually from tolls of the $1.55 billion
About
comes from tolls on the turnpike
Remaining
comes from tolls on the parkway
<em><u>To find the percent of the total revenue from turnpike:</u></em>

<em><u>To find the percent of the total revenue from parkway:</u></em>

<em><u>Summarizing the results:</u></em>
Percent of turn pike is 75%
Percent of parkway is 25%
Answer:
a) P(X = 75) = 0.30
(b) P(X ≤ 75)
= 0.2 + 0.4 + 0.3 = 0.90
(c) P(X > 50).
= 0.3 + 0.1 = 0.40
(d) P(X < 100)
= 0.2 + 0.4 + 0.3 = 0.90
(e) parts b, c & d are CDF
It is the second bubble because there can only be one x per y. For example, (1,3) and (1,4) isn't a function because the x which is 1 has too many y
