What is the solution to the following system of equations?
fenix001 [56]

Answer: (5,0)

Step-by-step explanation:

x - 3y =5 -----------(1)

2x + y = 10 ----------(2)

By elimination method, multiply eqn(1) by 2

2x - 6y = 10 ------------(3)

eqn(3) - eqn(2)

-7y = 0

Divide bothside by -7

y= 0

Now, we substitute the value of y in eqn(1)

x - 3(0) = 5

x - 0 = 5

x=5

Therefore,x=5 and y=0

mixer [17]

How many of the 3271 subjects used at least one prescription​ medication? Round to the nearest integer as​needed.)

Answer:

2902

Step-by-step explanation:

Let the total number of adults within the mentioned age bracket be n=3271

The proportion of adults who used at least one prescription medication be p=88.7%=0.887

The point estimate of population is given by

p=\frac {x}{n} where x is number of individuals in the sample with the specified characteristics and n is the sample size.

Let x be the adults who used at least one prescription medication

0.887=\frac {x}{3271}

x=3271*0.887=2901.377\approx 2902
