The population of these two cities combined in scientific notation is 11.9 x 10^{6}

Step-by-step explanation:

1a. Population of NYC is 8.1 x 10^{6}

1b. Population of LA is 3.8 x 10^{6}

2.To find total population of the two cities combined,

2a. Add population of NYC and LA

Total population = NYC's population + LA's population

Total population = (8.1 x 10^{6} ) + (3.8 x 10^{6} )

2b. Take 10^{6} common

Total population = 10^{6} * (8.1 + 3.8)

Total population = 10^{6} * 11.9

Therefore, the population of these two cities combined in scientific notation is 11.9 x 10^{6}

Dominic collected data on the favorite sports of the
trasher [3.6K]

Answer:

In Grade 8, 17% of students liked running

Step-by-step explanation:

Although this table is incomplete, there are still enough information to answer.

First, we need to be aware that the data here is written in decimal numbers, which is another way to write percentages.

In other words, 100% equals to 1, which is to say that if we multiply decimal number with 100 we'll get the percentage:

0.39 = 39%

0.04 = 4%

Another important thing to establish is that the value of decimal number DOES NOT mean the number of people, it only suggests the ratio:

0.26 does not mean 26 people etc.

Knowing this, from this incomplete table, we see that 0.17 students from grade 8 liked running. And now we know that 0.17 equals to 17%, which makes B the correct answer.
