Provate school in 2005
f(t)=85+18t
public school
g(t)=95+15t
graph
easy
replace g(t) and f(t) with y
y=18t+85
y=15t+95
input values for t and get values for y
y=18t+85
when t=0 y=85
when t=1 y=103
plot the oints (0,85) and (1,103)
y=15t+95
if t=0 then y=95
if t=1 then y=110
plot the points (0,95) and (1,110)
the easier way would just to be to solve the equatons but anyway
interscection point is (3 and 1/3,145)
so after 3 years (2008) it is about 145

I am think so opction (C).....
Answer:
The ratio of the difference of the two means to Sidney's mean absolute deviation = = 1.2195
Step-by-step explanation:
P.S - The exact question is -
Given - The means and mean absolute deviations of Sidney’s and Phil’s grades are shown in the table below.
Sidney’s Grades Phil’s Grades
Mean 82 78
Mean Absolute Deviation 3.28 3.96
To find - Which expression represents the ratio of the difference of the two means to Sidney’s mean absolute deviation?
Proof -
Given that Mean of Sidney Grades = 82
Mean of Phil's Grades = 78
So,
The difference of two means = 82 - 78 = 4
Also,
Given, Mean Absolute Deviation of Sydney = 3.28
Now,
The ratio of the difference of the two means to Sidney's mean absolute deviation = = 1.2195
Answer:
x = 7
Step-by-step explanation:
recognize that this is a right triangle with one of the internal angles = 45°. This means that the other angle not shown is 180 - 90 - 45 = 45°
This makes the triangle an isosceles triangle.
If so, x must be the same length as the other side adjacent to 90°
i.e x = 7
Answer:
x1= -6 x2=6
Step-by-step explanation:
x^2-10 = 26
x^2 = 26 +10
x^2 = 36
x = sqrt(36)
x = -6 or x = 6 because both 6 and -6 squared are equal to 36
