Answer:
The correct answer is 1/36
Step-by-step explanation:
The y-intercept of the linear equation of best fit, considering the slope and the means, is of -60.428.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For a line of best-fit, the y-intercept is given by:
The parameters in this problem are given as follows:

Answer:
A = $ 181,824 rounded
Step-by-step explanation:
A = $ 181,823.93
A = P + I where
P (principal) = $ 69,000.00
I (interest) = $ 112,823.93
1) A = (14)(24.5)-7^2
= 294m^2
2) A = (6)(7)+(17)(11)/2
= 135.5in^2
3) A = (8)(8)+(8)(4)/2
= 80cm^2
4) A = (7.5)(10)+(7.5)(5)/2
= 93.75cm^2
5) A = (18)(14)-9^2
= 171in^2
Answer:
<em>Number of nickels = 6</em>
<em>Number of dimes = 14</em>
<em>Number of quarters = 23</em>
<em></em>
Step-by-step explanation:
Total number of coins = 43
Let number of nickels = n
Let number of dimes = d
Let number of quarters = q
Money in n nickels =
Money in d dimes =
Money in q quarters =
Total money = $7.45
The sum of the numbers of nickels and dimes is 3 less than the number of quarters.
i.e.
Let us put the value in (1):
Putting the value of q in (1) and (2):
n+d = 20 .... (3)
(4) - (3):
d = 14
Now, from (3):
n = 6
<em>Number of nickels = 6</em>
<em>Number of dimes = 14</em>
<em>Number of quarters = 23</em>
