Answer:
The answer should be (5,-0).
Step-by-step explanation:
Answer:
60 miles
Step-by-step explanation:
f(x) = 2 + 0,5 * m + 6
38 = 2 + 0,5 * m + 6
38 = 8 + 0,5 * m
30 = 0,5 * m
m = 60 miles
Answer:
|x| = 25
Step-by-step explanation:
Original Equation:
|x - 4| = 21
Just add 4 to both sides
|x| = 25
Hope this helped :)
Answer:
6 seconds
Step-by-step explanation:
In second 1, the distance that separates them is 80 cm
Then, in second 2, it is an additional 76 cm which is 156
then 72, etc. etc.
From that, we can continue adding until we the total sum is 420.
80+76+72+68+64+60=420
That's 6 seconds
Not the most elegant solution but I think one of the simplest.
We are given frequency distribution in the question
to find the probability distribution from frequency distribution we need to divide frequency by total number of observations.
Here, total number of observations are 6+10+7+5=28
so , we will have probability distribution table as
X 0 1 2 3
P(x) .21 .35 .25 .17
probability distributiuon describes all possible values that a random variable can take within a given range.
frequency distribution is the presentation that presents number of observation in given interval.
