Two studies were completed in Georgia. One study in northern Georgia involved 3,000 patients; 84% of them experienced flulike sy
Alexeev081 [22]

Answer:

The northern Georgia study with a margin of error of 1.7%.

All else being equal, the study with the larger sample size has the smaller margin of error. So the result makes sense (as 0.84 is pretty close to 0.75)

Step-by-step explanation:

The best and most correct answer among the choices provided by the question is the third choice "The northern Georgia study with a margin of error of 1.7%."

All else being equal, the study with the larger sample size has the smaller margin of error. So the result makes sense (as 0.84 is pretty close to 0.75)

Helppp i need answer now will give points
Papessa [141]

Answer:

f(g(3)) = 3

Step-by-step explanation:

We are told to solve for f(g(3)). This is also saying f of g of 3.

To find f(g(3)), we need to plug 3 in for x in g(x), since it says g(3).

g(x) = 3(3) - 4

Solve.

= 9 - 4

g(x) = 5

Now, we plug that into f(x), because g(x) was placed inside f and replaces the x variable of f(x).

f(5) = 2(5) - 7

Solve.

= 10 - 7

f(5) = 3.

f(g(3)) = 3

Caleb is putting tile down in his bathroom and needs to know the perimeter of the floor. Two sides rectangular floor are 5 1/3 f
ladessa [460]

Answer:

  20 1/6 ft

Step-by-step explanation:

The perimeter is the sum of the lengths of the sides:

  2×(5 1/3 ft) + 2×(4 3/4 ft) = 10 2/3 ft + 8 6/4 ft

  = 10 2/3 ft + 9 2/4 ft . . . . change 6/4 ft to 1 1/2 ft

  = 10 8/12 ft + 9 6/12 ft = 19 14/12 ft  . . . . . use common denominator of 1/12 ft

  = 20 2/12 ft . . . . . . change 14/12 ft to 1 2/12 ft; next reduce that fraction

  = 20 1/6 ft . . . . perimeter of Caleb's bathroom
