There are 170 patients total and 100 out of 170 are given placebo and 70 are not so there is a 70/170 chance of not getting it but if you want a decimal then you divide the numerator 70 by the denominator 170 which is 0.41176... then you have to move the decimal point over to the right by two places so its 41.1176...% you can also round it to 41.12%

bazaltina [42]

The quotient of the fraction n³ / (2n - 6) ÷ n³ / (3n - 9) is 2/3

<h3 /><h3>How to solve fraction</h3><h3 />

n³ / (2n - 6) ÷ n³ / (3n - 9)

  • multiply by the reciprocal of n³ / (3n - 9)

= n³ / (2n - 6) × 1 / n³ / (3n - 9)

= 2n - 6 / 3n - 9

= 2(n - 3) / 3(n - 3)

= 2/3

Therefore, quotient of the fraction n³ / (2n - 6) ÷ n³ / (3n - 9) is 2/3

Lashonda is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.C
musickatia [10]
Answer:
30 < m
The solution would be (30, ∞)

Explanation:
For company A:
The charge is: $96 for any number of mileage ..............> I
For company B:
The charge is $75 fixed and 0.7 for each mileage m. This means that the charge is: 75 + 0.7m .................> II

We want the charge of company A to be less than the charge of company B. This means that we want I to be less than II.
Therefore,
96 < 75 + 0.7m
96 - 75 < 0.7m
21 < 0.7m
21/0.7 < m
30 < m

This means that for any mileage greater than 30, the charge of company A will be less than the charge of company B

Hope this helps :)
