Students in a science class investigated how the speed of sound changes with the air temperature outside. The data are shown in the scatterplot.
Based on the scatterplot, what is the best prediction of the speed of sound when the air temperature is 45°C?
350 m/s
355 m/s
360 m/s
365 m/s
Answers
Answer:360 m/s
Step-by-step explanation:
The best prediction of the speed of sound when the air temperature is 45°C is 360 m/s option third is correct also the graph shows a positive correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
As we can see in the graph:
When the air temperature is 10°C the speed of sound is around 337m/s
When the air temperature is 20°C the speed of sound is around 344m/s
When the air temperature is 30°C the speed of sound is around 348m/s
When the air temperature is 40°C the speed of sound is around 355m/s
From the above observation, the air temperature increases the speed of the sound increases.
So when the air temperature reaches 45°C the speed of the sound will be 360 m/s.
Thus, the best prediction of the speed of sound when the air temperature is 45°C is 360 m/s.

What type of triangle is this triangle?
acute scalene
obtuse isosceles
obtuse scalene
acute isosceles
Answers
Answer:
Obtuse scalene
Step-by-step explanation:
Answer:
obtuse scalene
Step-by-step explanation:
Scalene means that none of the sides are equal.
Isosceles means that two of the sides are equal.
Obtuse means an angle in the triangle is larger than 90 degrees.
Acute means all angles in the triangle are smaller than 90 degrees.
None of the sides are equal so this triangle has to be scalene and the angle in the bottom right is larger than 90 degrees so this triangle is obtuse.
Hope this helps! :)

Students surveyed boys and girls separately to determine which sport was enjoyed the most. After completing the boy
survey, it was determined that for every 3 boys who enjoyed soccer, 5 boys enjoyed basketball. The girl survey had a
ratio of the number of girls who enjoyed soccer to the number of girls who enjoyed basketball of 7:1. If the same
number of boys and girls were surveyed and 90 boys enjoy soccer, how many girls each sport?
Please help me and show how to solve this the best answer will get brainlesest
Answers
1. for the boys, 3 soccer is 5 basketball (in a group of 8 students).
2. for the girls, 7 soccer is 1 basketball (in a group of 8 students)
3. the question mentions 90 boys like soccer, which means we increased the number of boys surveyed 30x, since 3 times 30 is 90. now, we need to increase the girl numbers by 30 as well, giving us 210 girls who like soccer for every 30 who like basketball.
