<h3>Answers: 100 girls and 25 boys</h3>

============================================================

Explanation:

x = number of boys

The ratio of girls to boys is 4:1, meaning there are 4 times as many girls compared to boys. For example, the concert may have 40 girls and 10 boys.

For now, x is some unknown positive whole number. But we can say that 4x represents the number of girls, as we multiply by 4.

----------

We're told there are 75 more girls than boys, so,

number of girls = (number of boys) + 75

4x = x + 75

4x-x = 75

3x = 75

x = 75/3

x = 25

There are 25 boys and 4x = 4*25 = 100 girls.

We can see that 100-25 = 75 to show that there are 75 more girls compared to boys.

And also, the ratio 100:25 reduces fully to 4:1 after dividing both parts by the GCF 25. These two facts fully confirm the answers.

A bag contains 6 red tiles, 8 blue tiles, and 6 green tiles. A tile is drawn, the color recorded, and then the tile placed back

tester [92]

Answer:

9 red tiles

Step-by-step explanation:

Total number of tiles: $6+8+6=20$

Total number of red tiles: $6$

Probability of getting red in one draw: $\frac{6}{20}=0.3$

<em>This means that you would expect to get red $0.3$ or 30% of the times.</em>

<em>Hence, when you draw tiles 30 times from the bag, you would expect red to be picked 30% of 30 times. This is:</em>

So, you would expect to draw a red tile from the bag 9 times.

Logan wants to move to a new city. He gathered graphs of temperatures for two different cities. Which statements about the data

Bad White [126]

Answer:

The correct options are;

Therefore, City A is likely to have temperatures that remain fairly constant all year round because it has a compact interquartile range compared to that of City B

City B is likely to have more extreme temperatures with colder days in the winter and hotter days in the summer because the range is greater than that of A

Step-by-step explanation:

Here we have for City A

Maximum - Minimum = 10

Interquartile range =3

City B

Maximum - Minimum = 18.5

Interquartile range =9.5

Therefore, City A is likely to have temperatures that remain fairly constant all year round because it has a compact interquartile range compared to that of City B

City B is likely to have more extreme temperatures with colder days in the winter and hotter days in the summer because the range is greater than that of A.
