X = ones, y = fives
x + y = 19....x = 19 - y
x + 5y = 59
19 - y + 5y = 59
19 + 4y = 59
4y = 59 - 19
4y = 40
y = 40/4
y = 10 <=== there are 10 five dollar bills
x + y = 19
x + 10 = 19
x = 19 - 10
x = 9 <=== there are 9 one dollar bills
The 2 is in the tenths place, therefore we look at the number after to determine what to do with it. The number after is an 8 therefore we must round the two up to a 3. Therefore the answer is 310.3
57000 / 12 = $4750 monthly (before taxes)
Answer: b. number of trees
Step-by-step explanation:
The concept of geometric probability is basically use when we have continuous data .
Since it is impossible to count continuous data , but geometrically ( in form of length, area etc) we can count the outcomes in general to calculate the required probability.
Therefore, from the given options , Option b. "number of trees" would not be used for geometric probability because among all it is the only discrete case which is countable.
Rest of items ( a. area of a rug , c. length of time , d. length of a field) would be used for geometric probability,
