120 students don't have social media accounts
Step-by-step explanation:
Whether the sample is representative:
Estimate: ![\frac{3}{75} (3000)=\frac{9000}{75} =120](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B75%7D%20%283000%29%3D%5Cfrac%7B9000%7D%7B75%7D%20%3D120)
Hope this helps
Answer:
g(x) = 0.8x gal/dollar
Step-by-step explanation:
This is a direct relation, each gallon costs 1.25, 20 gal. costs 25.00, etc.
so
f(x) = 1.25x where x = number of gal. f(x) is the cost
The inverse relation is the reciprocal,
for each $1.00, we can buy 1/1.25 = 0.8 gal.
or
g(x) = 0.8x where x = amount, g(x) is number of gallons
Answer:
Step-by-step explanation:
Notice: The first vertex (0, 4) is further from the origin than is the second vertex (3, 0), in the y-direction and the x-direction, respectively.
The standard equation of an ellipse with center at the origin is
x² y²
------ + ------ = 1
a² b²
and a represents the greater distance from the origin to one covertex or the other. In this case we let a = 4 and b = 2. Then we have:
y² x²
---- + ------ = 1 which is the equation of this ellipse in final
4² 3² finished form.
