Answer:
The required probability is 0.3717.
Step-by-step explanation:
Consider the provided information.
There are approximately 100 species of venomous snakes, but only about 12 have a deadly bite.
zoo randomly selects one snake from each of five different species to show visitors.
The total number of ways to select 5 different species out of 100 are:
We need to find the probability that exactly one of the five snakes shown is deadly.
That means out of 12 deadly bite we need to select only 1.
Thus, the number of ways are:
Hence, the required probability is:
The required probability is 0.3717.

20:24 is My Answer
Step-by-step explanation:
y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio
proportion is an equation with a ratio on each side. It is a statement that two ratios are equal.
For example 2/5 is Equal to 4/10 this Would be A Example Of a Proportional relationship!
Answer:
-30
Step-by-step explanation:
Answer:
Yes, it is possible if the sweaters on sale are $7.40 each.
Step-by-step explanation:
The sweaters each cost $37. To purchase all four (for herself and 3 sisters) without a sale would be 4(37)= $148.
40% off the regular price would be 0.40(148)= $59.20 savings. She would spend 148-59.2= $88.80.
Is it possible to buy two regular price sweaters and two on sale for $88.80?
2(37)=$74. If we subtract from the sales total, 88.80-74=14.80. This means the two sweaters on sale must each be $7.40. It is possible to save 40%.
SO we know he spent a total of $24
We also know the popcorn was $6, so we subtract 6 from 24
24-6=18
And we know he bought 2 tickets for a total of $18, so we will divide 18 by 2
18/2=9
Each ticket was $9
Hope this helps!
