Answer:
20
Step-by-step explanation:
The expected value of a toss is:
E(X) = (0.10) (3) + (0.30) (1) + (0.60) (0)
E(X) = 0.6
If she scores an average of 0.6 points per toss, then the expected number of tosses needed to get 12 points is:
12 / 0.6 = 20
Using a random number table, we can assign digit 0 as a 3-point hole, digits 1-3 as a 1-point hole, and digits 4-9 as no points. Read the digits and add the points until you get 12 points. The number of digits read is the number of beanbag tosses.
Part (a)
Replace every 'a' with 5.2 and replace every 'b' with 4.7
Then use your calculator to evaluate.
3a + b^3 = 3*5.2 + (4.7)^3 = 119.423
<h3>Answer: 119.423</h3>
===============================================
Part (b)
The true value is 119.423 which is the result of part (a)
The estimated value is 140
Subtract the two values
140-119.423 = 20.577
and divide that over the true value
20.577/140 = 0.14697857142858
Which, when rounded to 4 decimal places, we get 0.1470
Move the decimal place over to the right 2 spots to get 14.70%
<h3>Answer: 14.70% error (approximate)</h3>
Answer:
24 grams
Step-by-step explanation:
Since there are three of them, I multiply by the mass, which is 8, and get 24 grams. Hope this helps!
