Answer:
<h2>Graph
D</h2>
Step-by-step explanation:
When the process starts, the water is flowing slowly, since there is only 1 valve open. That represents the part on this where the line is going almost horizontally.
When the operator opens the second valve also, then there will be more water released at once, which means that the water will come out faster, and take less time. That represents the middle part of the line, which is almost vertical.
When the operator shut's down the second valve, then the process gets slower, and that represents the part which is going slow again. And that represents the 3rd part, where the line is going almost horizontal again.
Mark me brainliest if this could help! Thanks!
What is the mean, median, and mode of 3,8,13,4,9,15,7,8,5,
Stella [2.4K]
Answer:
Mean: 8
Median: 8
Mode: 8
Step-by-step explanation:
Find the average
Mean: 3 + 4 + 5 + 7 + 8 + 8 + 9 + 13 + 15 = 72
Divide by the amount on numbers: 72 / 9 = 8
8 is the average
Find the middle
Median: 3, 4, 5, 7, 8, 8, 9, 13, 15
8 is the middle
Find the most common
Mode: 3, 4, 5, 7, 8, 8, 9, 13, 15
8 is most common
Answer:
9.A 10.A its a little confusing to explain but yard just isn't a metric unit and humans don't weigh tons or pints
Answer: 18 tablespoons
Explanation: for the water, you have to multiply the 2 gallons by 3 if you want to get 6 gallons. then, you also multiply 6 tablespoons by 3 to get 18 tablespoons. you can see the ratio 2:6 is the same as the ratio 6:18, so you know it’s correct!
Answer:
As square root of 9 can be written in the required form for being a rational number, so it is a rational number
Step-by-step explanation:
First of all we'll define rational numbers.
A number that can be written in the form p/q where p and q are integers and q≠0 is called a rational number.
Now we have to check if 
is rational or not, we will check if it can be written in the form p/q
As square root of 9 can be written in the required form for being a rational number, so it is a rational number
