Answer:
Kayla, learn this, :D more math is based on it. Just learn it, just memorize the following
Step-by-step explanation:
m = slope
m = rise / run
m = y2 - y1 / x2 - x1 ( this is still rise over run but in point form )
they give us two points to plug into the above formula
P1 = (-4, 8 ) in the form of ( x1, y 1 )
P2 = (2, -1) in the form of (x2, y2 )
now plug those into the above formula
m = ( -1 - 8 ) / ( 2-(-4) )
m = -9 / ( 2 + 4 )
m = -9 / 6
m = - 3/2
since we know the slope now , we can use the point slope equation of
y - y1 = m ( x - x1)
use the m we found and either point , P1 or P2
y - 8 = -3/2(x -(-4) )
y-8 = -3/2(x + 4)
y-8 = -3/2x - 6
y = -3/2x -6 + 8
y = -3/2x + 2
there you go :)
3000/150 will give you 20. So after 20 she will have no money left
Answer:
1.20
Step-by-step explanation:
Let mean be represented by M and standard deviation by d. The score will be x and sample number of games be n
To get the test statistic, t for Fernanda's test, we use the formula
Substituting 156 for mean, M then 150 for score x and 30 for standard deviation while 36 for n then
t=1.20 when put in two decimal place
Answer:
A. 1/8, 2/3, 9/10, 7/6
Step-by-step explanation:
Multiply the fractions to have a common denominator:
1/8 x 11.25/11.25 = 11.25/90
2/3 x 30/30 = 60/90
9/10 x 9/9 = 81/90
7/6 x 15/15 = 105/90
Now easily compare:
11.25/90 < 60/90 < 81/90 < 105/90
