24x3=72
Answer:
C) 0.179
Step-by-step explanation:
Since the trials are independent, this is a binomial distribution:
<u>Recall:</u>
- Binomial Distribution -->
denotes the probability of 
successes in 
independent trials
denotes the probability of success on each of trials
denotes the probability of failure on the remaining 
trials
denotes all possible ways to choose things out of things
<u>Given:</u>
<u>Calculate:</u>
Therefore, the probability that the archer will get exactly 4 bull's-eyes with 10 arrows in any order is 0.179
B)
To go from fig. 1 to fig.2 you would dialate 1:3, or 3 times the size
c)
The opposite would be true since you are going the opposite direction. 3:1, 1/3 of the size
Hope this helps:)
Answer:
Step-by-step explanation:
The lengths can be found by considering their ratio:
short : long = 1 : 5
The sum of the ratio units is 1+5 = 6, and the sum of the lengths is 144 inches. That means each "ratio unit" stands for (144 in)/6 = 24 inches of length.
The lengths are ...
1 : 5 = 24 in : 120 in
The pieces are 24 inches and 120 inches in length.
__
Equivalently, you can let s represent the shorter length. Then 5s is the longer one, and their total is ...
s +5s = 144
s = 144/6 = 24
5s = 5(24) = 120
The lengths are 24 inches and 120 inches.
4p-5p+30 just multiply everything in the brackets by what's not
