we have that
Part c)
the probability is equal to
P=0.14+0.27+0.58
<h2>P=0.99</h2>
because is the sum of
x=1, x=2 and x=3
Part D
the probability is
P=0.01+0.14+0.27
<h2>P=0.42</h2>
because is less than or equal 2
1. The graph is hard to read. I would say about 4.3
2. It is very close to the same number 4.5
3. The 19-24 age group has the lowest number of wrecks in December
4.Teenagers and early 20's is the intended audience to show them the number or accidents caused by distracted driving by people of their age.
The common difference is 19-7 = 31-19 = 12, so this is an arithmetic sequence. The initial term (when n=1) is 7.
The explicit formula for the terms of an arithmetic sequence is
an = a1 + d(n-1)
where "a1" is the first term and "d" is the common difference. The formula that matches a1=7 and d=12 is
B. a(n) = 7+(n-1)·12
Use the Pythagorean Theorem to solve this question.
I use the ^ to tell that it is squared
so 9 squared +3 squared =x squared
9^2+3^2=x^2
x^2= radical 90
x ≈ 9.5 feet
