It takes the earth 24 h to complete a full rotation. It takes Mercury approximately 58 days, 15 h, and 30 min to complete a full

Nastasia [14]

It takes Mercury approximately 58 days, 15 h, and 30 min to complete a full rotation..

We are going to write the time not in days, hours and minutes, but only hours.

This means that we have to write 58 days as hours and 30 minutes as hours.

1 day is 24 hours, so 58 days are

58*24=(50+8)*(20+4)=50*20+50*4+8*20+8*4=1,000+200+160+32

=1,200+192=1,392 (hours)

60 minutes are 1 hour, so 30 minutes are 0.5 hours.

Thus

58 days, 15 h, and 30 min are (1,392+15+0.5) hours = 1,407.5 hours

Answer: 1,407.5 hours

Roll dice and flip coin

scZoUnD [109]

Roll dice and flip coin:
Probability of rolling a cube and getting a 3 = 1/6 .
Probability of flipping a coin and getting HEADS = 1/2 .

Probability of both = (1/6) x (1/2) .
You do the multiplication.

4 blue, 2 green, 6 red
Probability of a blue on the first draw = 4 out of 12 marbles = 1/3 .
Without putting the blue back in ...
Probability of a red on the next draw = 6 out of 11 marbles = 6/11 .

Probability of both = (1/3) x (6/11) .
You do the multiplication.

Exciting Entertainment

We can deduce that the student's gender provides information about their entertainment choices.

Given the following data:

Expenses on digital music = $2.6 billion dollars.

Expenses on video games = $24.7 billion dollars.

<h3>Describing and analyzing the data.</h3>

The data was gathered from a random survey which was conducted by sixth-grade students to determine the number of digital music (songs) that was downloaded by each student to their respective media player in the past two months as shown in the table in the image attached below.

<h3>What is a median?</h3>

A median can be defined as the middle number (center) of a sorted data set, which is when the data set is arranged from the least to greatest (ascending order) or greatest to least (descending order).

For the girls:

Median = 50.

For the boys:

Median = 33.

A mean refers to a ratio of the sum of the total number in a data set to the frequency of the data set.

For the girls:

Mean = 46.

For the boys:

Mean = 34.

In this context, we can deduce that the student's gender provides information about their entertainment choices.
