Answer:
<h2>slope = -10/7</h2>
<u>Step-by-step explanation:</u>
co-ordinates = (6,-2) (5,-4)
slope = (y² - y¹) / (x² - x¹)
slope = (-4 - 6) / (5 - (-2))
slope = (-10) / (5+2)
slope = (-10) / 7
slope = -10 / 7
Answer:
-5
Step-by-step explanation:
do the exponets first. -6 squared is positive 36 because negative times a negative is a positive.
next you multiply 4 and 7 and get 28
you have 28-36+2 and that equals -5
Answer:
it is B
Step-by-step explanation:
i have taken the test
Answer:
See method below.
Step-by-step explanation:
m/n + n/3 = 2
2/m + n = 4
First eliminate the fractions by multiplying the first equation by 3n:-
3m + n^2 = 6n...........(1)
and the second equation by m:-
2 + mn = 4m..............(2)
Now we solve using substitution:-
From equation (2):-
4m - mn = 2
m = 2 / (4 - n)
Now substitute for m in equation (1):-
6/ (4 - n) + n^2 = 6n
6 + n^2(4 - n) = 6n(4 - n)
6 + 4n^2 - n^3 = 24n - 6n^2
n^3 - 10n^2 + 24n - 6 = 0
This will not factor so we could solve this using graphical software.
To find the values of the variable m we substitute the found values of n into one of the original equations and solve for m.
The required percentage of leagues that have fewer than 7 teams is 25%
Box plots and Quartiles
A boxplot is a standardized way of displaying the distribution of data based on a five number summary. It consists of the minimum point, m<u>aximum point, quartiles and medians</u>
<u />
From the given boxplot, you can see that football league that have fewer than 7 teams occupies 1/4th of the total team. Hence the required peprcentage will be;
Percentage of those that have fewer than 7 teams = 1/4 * 100
Percentage of those that have fewer than 7 teams = 25%
Hence the required of leagues that have fewer than 7 teams is 25%
