Hope this helps!!
Answer:
See below ~
Step-by-step explanation:
<u>(a) Mean of the data</u>
- 2.4 + 1.6 + 3.2 + 0.3 + 1.5 / 5
- 9/5
- <u>1.8</u>
<u></u>
<u>(b) New mean after each data point increased by 10</u>
- 12.4 + 11.6 + 13.2 + 10.3 + 11.5 / 5
- 59/5
- <u>11.8</u>
<u></u>
<u>(c) New mean after each data point doubled [from (b)]</u>
- 24.8 + 23.2 + 26.4 + 20.6 + 23 / 5
- 118/5
- <u>23.6</u>
Answer:
See below in bold.
Step-by-step explanation:
For the fair coin Prob(head) = 1/2 and Prob(Tail) = 1/2.
For the biased coin it is Prob(head) = 2/3 and Prob(Tail) = 1/3.
a) Prob(2 heads) = 1/2 * 2/3 = 1/3.
b) Prob(2 tails) = 1/2 * 1/3 = 1/6.
c) Prob(1 head ) = Prob(H T or T H) = 1/2 * 1/3 + 1/2 * 2/3) = 1/6+1/3 = 1/2.
d) Prob (at least one head) = prob (HH or TH or HT) = 1/3 + 1/2 =<em> </em>5/6.
<h3>
<u>Explanation</u></h3>
f(a) means the value of f(x) is ... when x = a. That means if we substitute x = 3, we would get f(3).
f(3) also means the value of f(x) is ... when x = 3.
f(x) can also be defined as y // f(x) = y
You can find the value of f(x) at specific domain from the graph by looking at x = 3 then look up to where the point or where the graph passes. From the graph, when x = 3 as we look up and the graph passes y-coordinate at 1.
Therefore we can say that when x = 3, y = 1.
<h3>
<u>Answer</u></h3>
f(3) = 1
