Answer:
Step-by-step explanation:
1) Each of the ratios can be reduced to 1 : 5, Since both can be reduced to the same ratio, the do form a proportion.
4 : 20 = 1 : 5
6 : 30 = 1 : 5
__
2) The first ratio can be reduced to 1/2. The second ratio is not 1/2 and cannot be reduced. Since they are different ratios, they do not form a proportion.
9/18 = 1/2
3/8 = 3/8
Answer:
1.242% probability that the second one selected is defective given that the first one was defective
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
We have
484 containers
7 are defective
a) What is the probability that the second one selected is defective given that the first one was defective?
After the first one was selected(defective), we have
483 containers
6 defective
6/483 = 0.01242
0.01242 = 1.242% probability that the second one selected is defective given that the first one was defective
Answer:
A
Step-by-step explanation:
A is the correct answer have a great day
You know that one integer is a negative integer, as the product is negative- and if the sum is zero, then the absolute value of the two integers are equal. Thus, the integers are +/- sqrt(36). or +/- 6.
Example: 6 and -6
Your welcome.
