Answer: At most 3
Step-by-step explanation:
If there are 25 white socks and 25 red socks, a matching pair would be picked in at most 3 times.
The first sock you pick would be either White or Red
The second sock you pick would be either white or red again which means that you now either have 2 whites, 2 reds or 1 white and 1 red.
The third sock you pick will either be white or red once more. At this point you will either have 3 whites, 3 reds, 2 whites and 1 red or 2 reds and 1 white.
You will therefore have at least a matching pair after 3 tries.
Answer:
Constant of proportionality
K= 16.5 gallons per minute
Step-by-step explanation:
Time t (minutes) Water g (gallons)
For t= 1, g= 16.50,
for t= 1.5 ,g= 24.75
For t= 2,g= 33
Let the function be
Gallons g= k(time t)
Where k is the constant of proportionality
16.5= k(1)....for when t= 1
24.75= k(1.5) ..for when t= 1.5
Solving gives
8.25=k(0.5)
8.25/0.5= k.
16.5 = k
K= 16.5 gallons per minute
Answer:
9000 school graduates.
Step-by-step explanation:
Given,
Only 6/10 graduates receive a diploma and 5400 students graduated last year.
6 people regents exam when the total graduates are = 10
1 people regents exam when the total graduates are = 10/6
5400 people regents exam when the total graduates are = (10/6)*5400
= 9000
So, the total number of high school graduates is 9000.
For this case, the first thing you should do is define variables:
x: number of days
y: money available
We now write the linear function that represents the problem:
y = -7x + 150
Therefore, the x axis is labeled as:
Number of days.
Answer:
The x axis would be labeled:
Number of days
