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.
Answer:
B. n / 4; 6
Step-by-step explanation:
Let
n = the unknown number
the quotient of a number and four
= n/4
When n = 24
The expression becomes
= n/4
= 24/4
= 6
B. n / 4; 6
The answer is 3 / 3
Step-by-step explanation:
Cancel negative with positive then find the answer
Answer:
1 hour and 7.5 minutes
Step-by-step explanation:
We have the following information:
Jose makes 1 / 1.5 of the job per hour. It is his rate of work in addition to that the partner makes 1 / 4.5 of the job per hour. It is his rate of work.
Thus:
1 / 1.5 + 1 / 4.5 = 1 / x
0.8898 = 1 / x
x = 1 / 0.8888
x = 1.125
Hence, it will take 1 hour and 7.5 minutes for them to complete the job working together.
Solution:
from; f(2)=3
f(2n) nf(2)
(3)(n)
therefore :
f(32)=f(2.16)
f(32)=16f(2)
f(32)=(16)(3)
f(32)=48 final answer
