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.

A teacher surveys a sample of students from Lake Middle School. He asks the students where they’d like to go for a field trip. He records these results:
80 choose the aquarium.
60 choose the science center.
30 choose the planetarium.
40 choose the farm.
The teacher wants to figure out the relative frequency of a student choosing the aquarium. He will then estimate how many students out of all 1000 at the school are likely to choose the aquarium.
4) Write and solve a proportion that the teacher can use to estimate how many students in the whole school would choose the aquarium. Show your work.
Answers
Answer:
210 student's
Step-by-step explanation:
80 students chose the aquarium.
60 students chose the science center.
30 students chose the planetarium.
40 students chose the farm.
The students can't vote for more than one place, so you just add all the numbers together.
80 + 60 + 30 + 40 = 210 students

Answer:
a¹⁸b²⁴c⁵⁴
Step-by-step explanation:
(aᵇ)ᶜ = aᵇᶜ = aᵇ×ᶜ
(-aⁿ)ᵒᵈᵈ = -aⁿ
(-aⁿ)ᵉᵛᵉⁿ = aⁿ
aⁿ × aⁿ = aⁿ⁺ⁿ
_________
In this situation, 6 is an even exponent which means that the negative coefficient of this 9th degree monomial will be positive. Now the only step is to multiply the exponents by the exponent outside of the perenthesis which is 6.
so (-a³b⁴c⁹)⁶ = ((-a³)⁶(b⁴)⁶(c⁹)⁶) = ((a³ˣ⁶)(b⁴ˣ⁶)(c⁹ˣ⁶)) = ((a¹⁸)(b²⁴)(c⁵⁴)) = a¹⁸b²⁴c⁵⁴
