Answer:
Step-by-step explanation:
Given that a hat contains n coins, f of which are fair, and b of which are biased to land heads with probability 2/3
A coin is drawn from the hat and tossed twice. The first time it lands heads, and the second time it lands tails.
There are two possibilities. Either fair coin is drawn or biased is drawn.
Let A1 = I coin drawn and A2 = II coin is drawn.
B= the first toss lands head and II tails.
Prob it is a fair coin =
Formula: Area = length * width
Substitute in what you know: 42 = length * 6
Divide both sides by 6 to get the length: length = 7
Formula: Perimeter = 2 (length + width)
Substitute in what you know: P= 2 (7+6)
Solve: Perimeter = 26 ft
To solve this, you need to plug in your solution to your variable.
g² + 14g + 40
5² + 14(5) + 40
25 + 70 + 40
So, your area would be 135.
Out of your 4 options, you need to find out which dimensions create 130.
20 × 2 = 40
4 × 12 = 48
12 × 7 = 84
15 × 9 = 135
Your dimensions are 15ft by 9ft :)
Hope this helps!
Answer:
B. [144, 174]
Step-by-step explanation:
Given
Total Weight Range = Not less than 145lb and Not more than 175lb
Required
Determine the actual weight range
Let x represent the total possible weight of a bodybuilder
From the question, we understand that the total weight is within the range of 145 to 175. i.e.
Also from the question, we understand that the bodybuilder's cloth adds 1 lb to the total weight;
The next step is to subtract this 1 lb from the range of total weight to get the actual weight range
This is as follows
This gives
<em>From the list of given options, the correct answer is [144,174]</em>
