Answer:
a) CD = 5.7
b) ED = 3.05
Step-by-step explanation:
Triangle ABE is similar to triangle ACD by AA similarity. This means we can write the proportions ...
a) CD/BE = AC/AB
CD = BE(AC/AB) = 3.8(12.3/8.2)
CD = 5.7
__
b) ED/AD = BC/AC
ED = AD((AC -AB)/AC) = 9.15(12.3 -8.2)/12.3
ED = 3.05

A quality-assurance worker wants to systematically sample 120 glass jars each day from a conveyor belt in a factory that puts out 3,600 jars each day. If the worker will select every kth jar, what is the best value of k for the worker to use? Enter a whole number.
Answer:
The best value of k for the worker to use is 30.
Step-by-step explanation:
Sample of 120 jars from a set of 3,600.
If the worker will select every kth jar, what is the best value of k for the worker to use?
The best case would be starting at 0 and ending at 3600, finding 120 values, which means that k is given by the division of 3600 by 120. So
[tex]k = \frac{3600}{120} = \frac{360}{12} = 30[/tex]
The best value of k for the worker to use is 30.

Find the probability that an adult resident has 3 or more
vehicles. Give your answer as a number between 0 and 1.
Answer:
Step-by-step explanation:
Number of Vehicles Probability
0 0.04
1 0.41
2 0.38
3 0.13
4 0.03
5 0.01
X= 1
.13+.03+.01=0.17 (the amount with 3 or more cars)
0.17/1(Total amount of all probability)= 0.17 has 3 or more cars.
Probability is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
The probability that an adult resident has 3 or more is 0.17
What is probability?
It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
The probability distribution of the number of vehicles is given as,
P(x) where x is the number of vehicles.
P(0) = 0.4
P(1) = 0.41
P(2) = 0.38
P(3) = 0.13
P(4) = 0.3
P(5) = 0.1
The probability that an adult resident has 3 or more.
= P(3) + P(4) + P(4)
= 0.13 + 0.03 + 0.01
= 0.17
Thus,
The probability that an adult resident has 3 or more is 0.17
