Step-by-step explanation:
y-13<6
y<6+13
y<19
hope it helps.
We know that
To determine the intervals you will need to find the lowest and highest numbers
lowest number------> 1
highest number-----> 35
(1 and 35).
A general rule would be 5-7 intervals,
so
I will choose 5.
Here are the intervals with the number of people that were in each:
[1-7] -----------> (9)
[8-14] ---------> (14)
[15-21] --------> (8)
[22-28] ------> (3)
[29-35]-------> (5)
The total of the frequencies was 39 people, and that is how many numbers there are.
Answer:
y = -3x + 30
Step-by-step explanation:
First, find the slope using the slope formula:
m = (y2 - y1) / (x2 - x1)
m = (9 - (-3)) / (7 - 11)
m = -12/4
m = -3
Next, find the y-intercept by substituding one of the two points into what the equation is so far:
y = -3x + b
(7, 9)
9 = -3(7) + b
9 = -21 + b
30 = b
Now you have the full equation:
y = -3x + 30
Answer:
2/9
Step-by-step explanation:
B
