Why is random sampling preferred over other methods of sampling?

Mathematics
1 answer:
Anna [14]3 years ago

Answer:

2.

Step-by-step explanation:

It's a random sample, so anyone could be sampled. Everyone has the same rate of being sampled, therefore the results are fair and equal.

The function f(x) = 2x2 + 2 represents the rate of a bus traveling in miles per hour. The function g(x) = x + 2 represents the t
AlekseyPX

Answer:

  (f • g)(3) = 100, the distance in miles the bus traveled

Step-by-step explanation:

The product of (miles/hour) and (hours) is (miles), so only answers with units of distance are applicable. The numbers are ...

  f(3) = 2·3² +2 = 20 . . . . miles per hour

  g(3) = 3+2 = 5 . . . . hours

so (f·g)(3) = f(3)·g(3) = 20·5 = 100 . . . . miles

This means only the first answer choice is applicable.

An athlete saved $184. She bought a glove, cleats, and a hat. After her purchases, she still had $39.50. The glove cost three-fi
Mumz [18]

Answer: Cost of the gloves is $ 51

Cost of the cleats is $85

Cost of the hat is $8.50

Cleats cost $76.5 more than the hat.

Step-by-step explanation:

Let the cost of gloves be 'g'

Let the cost of cleats be 'c'

Let the cost of hat be 'h'

Total money she had = $184

Money left after purchasing = $39.50

Money spent = 184 - 39.50

=$144.50

g = (3/5) c

(5/3) g = c

h = (1/6) g

g + c + h = 144.50

g + (5/3) g + (1/6) g = 144.50

(6g + 10g + g) /6 = 144.50

(17g) /6 = 144.50

(17/6) g = 144.50

g = (144.50) (6/17)

g = $51

c = (5/3) g

c = (5/3) (51)

c = $85

h = (1/6) g

h = (1/6) (51)

h = $8.5

Cost of the gloves is $ 51

Cost of the cleats is $85

Cost of the hat is $8.50

Cleats cost $76.5 more than the hat.
