Answer:
The number of days are independent and the total number of minutes are dependent.
The required model for the situation is 
The table is shown below:
Step-by-step explanation:
Consider the provided information.
Joshua spends 25 minutes of each day reading. Let d be the number of days that he reads, and let m represent the total minutes of reading.
We need to determine which variable is independent and which is dependent.
Here, the number of days are independent and the total number of minutes are dependent.
If he spends 25 minutes each day. So the total number of minutes in d days are:
The required model for the situation is
Now make the table which showing the number of minutes spent reading over 7 days.
Substitute the value of d from 1 to 7 in
Number of days(D) Minutes(M)
1 25
2 50
3 75
4 100
5 125
6 150
7 175
10.5/7 is all you would need to do to find your answer of 1.5 yards of ribbon per bow.
30 = 5(m) + 7(n)
5(a) + 30 = 7(a)
(a) is the number of visits!
15 = (a)
5(15) = 75 + 30 = 7(15) = $105
Answer:
y = 20/3 * x + 125/3
Question 4 : 3 hours study for score 55 (?)
Step-by-step explanation:
2 points (2, 55) (5,75) were chosen to plot the line of best fit, cuz 5 on the above and 5 below it.
y = mx + b
m = (75 - 55) / (5 - 2) = 20/3
b = y - mx = 55 - (20/3) * 2 = 125/3
Equation: y = 20/3 x + 125/3
Answer:
y = 10/3x + 20
Step-by-step explanation:
First, we need to find the slope of the function. We can do that by using two points and inserting them into the slope formula. It can be any two but I'll just pick (3, 30) and (6, 40).
m = y₁ - y₂ / x₁ - x₂
m = 30 - 40 / 3 - 6
m = -10/-3
m = 10/3
Now we know the slope is 10/3.
In slope-intercept form, the y-intercept is the constant at the end of the equation. The table of values tells us that the y-intercept is located at (0, 20). So the equation of the linear function is y = 10/3x + 20.
