Elena L [17]3 years ago

Answer:

Option D

Step-by-step explanation:

Going through the choices will help determine which option best simulates the random selection of a voter.

<u>Flip a coin three times, and assign outcomes as follows: HHH, HHT, or HTH = Nava; HTT, THH, or THT = Jensen; TTH = Moretti, TTT = Chang.</u>

Given that it is a random selection of the 4 candidates, it means the probability of choosing either one of them is equivalent. From the option, it can be found that Nava and Jensen have a higher chance of being voted than Moretti and Chang, which would not fit the criteria of being randomly selected.

<u>Roll a number cube, and assign outcomes as follows: 1 or 2 = Nava, 3 or 4 = Jensen, 5 = Moretti, 6 = Chang.</u>

Again, Nava and Jensen have a higher chance of being voted than Moretti and Chang. Therefore, this is not the correct option to simulate random selections of the 4 candidates.

<u>Roll a number cube, and assign outcomes as follows: 1, 2, or 3 = Nava, 4 = Jensen, 5 = Moretti, 6 = Chang.</u>

Nava has a higher chance of being voted, so this option does not fit the stimulation.

<u>Flip a coin twice, and assign outcomes as follows: HH = Nava, HT = Jensen, TH = Moretti, TT = Chang</u>

In this scenario, all 4 candidates have an equal chance of being voted, so this option would best simulate the random selection of a voter from the city.

Hope this helps :)

galina1969 [7]
To answer the problem above, we first need to know the difference in hours.
from month 1 to 2 the difference in hour is 1.5.
Month 2 to 3 =  3.5 to 5 = 1.5
Month 3 to 4 = 5 to 6.5 = 1.5
Month 4 to 5 = 6.5 to 8 = 1.5

The answer is C. Linearly, because the table shows that hours increase by an equal factor for an equal increase in months. which is 1.5 hours per month.

Solve the system by substitution. Check your solution.
postnew [5]

Answer:

(9,126)

Step-by-step explanation:

Make sure x and y are on the same side

0.5x+0.25y=36\\16x-1y=18

Eliminate y by multiplying the first equation by 4 then adding both equations together

2x+1y=144\\16x-1y=18\\18x=162\\x=9

Plug the x value (9) into one of the equations

16(9)-1y=18

Solve

16(9)-1y=18\\144-1y=18\\144=18+1y\\126=y

x=9, y=126
