Answer:
y = 1/5x
Step-by-step explanation:
Here, we have a direct relationship between the distance from lightning and the time it takes to hear thunder
Let the distance from lightning be y and the time it takes to hear thunder be x
If k is the proportionality constant, then;
y = kx
Now, let’s calculate k , given x 10 seconds and y = 2 miles
2 = 10k
k = 2/10 = 1/5
So the equation for the given situation is;
y = 1/5x
Answer: The correct option is
(B) 
Step-by-step explanation: We are given to select the rational number that is also an integer :
We have
not an integer.
an integer.
0.24 and 2.4 are not integers, they are just rational numbers.
Thus, the required rational number that is also an integer is
Option (B) is CORRECT.
Answer:
The 75th percentile is 16.5
The middle 50% values are between 8 and 16.5
Step-by-step explanation:
The end of the gray box represents the 75th percentile. We see the end of it hovers after 15, so 16.5 is the most reasonable answer.
The box represents the 25th percentile to the 75th percentile and hold the middle 50% the box starts on 8 and ends on 16.5.
Therefore, the middle 50% is between 8 and 16.5.
7 trials = 0.06×7=0.42
2 trials = 0.06×2=0.12
So 2/7 trials = 0.12/0.42
It is a trinomial because it has 3 terms.
