Hello :
<span>g(n) = n2 − 16n + 69
=( n²-16n+64)-64 +69.....(</span><span> completing the square)
</span>g(n) = (n-8)² +5...... (<span>the vertex form)
the vertex is : (8,5)
</span><span>the axis of symmetry is the line : n = 1</span>
Answer:
6:54?
Step-by-step explanation:
Im really sorry if it's wrong but I'm pretty sure thats the answer since its a ratio
$200 x 0.00295
= $0.59
The price of the toy car in 1968 was $0.59
Part A
Use the binomial probability distribution formula.
p = 0.54 = probability of getting a purple marble
n = 5 = sample size
x = 2 = number of purple we want to get

The
portion is from the nCr combination formula. The exclamation marks indicate a factorial.
Alternatively, you could use Pascal's Triangle for that portion.
<h3>Answer: 0.283831776</h3>
This decimal value is exact. Round it however you need to.
============================================================
Part B
To find the expected value, aka the mean, we multiply the sample size and probability of getting a purple marble on any single selection.
n*p = 5*0.54 = 2.7
<h3>Answer: 2.7</h3>
