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
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.

Choose all of the correct statements.
Answer:
1. The diameter is 2 times the Lenght of the radius.
2. C = πd
3. π = C/d
4. d = C/π
5. The circumference is 3.14 times the diameter.
Step-by-step explanation:
Diameter (d) of a circle is 2 times the radius (r). Mathematically, it is written as:
d = 2r
From:
d = 2r
Divide both side by 2
r = d/2
The radius is half the diameter.
Circumference (C) of a circle is given by:
C = 2πr
C = π2r
Recall:
d = 2r
C = πd
C = πd
Divide both side by d
π = C/d
C = πd
Divide both side by π
d = C/π
C = πd
π = 3.14
C = 3.14 × d
Thus, the circumference is 3.14 times the diameter.
SUMMARY:
The correct statement from the above illustration is given below:
1. The diameter is 2 times the Lenght of the radius.
2. C = πd
3. π = C/d
4. d = C/π
5. The circumference is 3.14 times the diameter.

In a survey of 160 people who have reptiles as pets, 40% have a pet snake. Of those with a pet snake, 25% also have a pet lizard. Of those who do not have a pet snake, 75% have a pet lizard.
Part A
Enter the correct answers in the boxes to construct a two-way frequency table to display the data.
Part B
What percentage of those surveyed have a pet lizard?
Part C
What percentage of those surveyed have both a snake and a lizard?
Percentage of people having Lizard = 55% , Percentage of people having both Lizard & Snake = 10%
Important Information : Percentage people having pet snake = 40%
C] Percentage people having pet lizard, along with pet snake = 25% of those having pet snake = 25% of 40% = 10% {Percentage of people having both snake & lizard)
Percentage of people having pet snake only = 75% of those who don't have snake = 75% of ( total - 40%) = 75% of 60% = 45%B] Total percentage of people having pet lizard = 10% + 45% = 55%

Which of the following values for x is true for 4x > 10
x = 34
x = 2
x = 2.5
x = 3
help!
Answer:
2.5
Step-by-step explanation:
its just 4 x x so you just times 2.5 by 4
Answer:
you can put 34 or 3 your choice!
Step-by-step explanation:
Ok so how you would find this out is first you put 4(x)>10
and you'll swap out the x for each number choice and 2.5 is the one that fits...
4(34)>10 = 136>10 yes
4(2)>10 = 8>10 well no bc 8 is less than 10
4(2.5)>10 = 10 = 10 not 10>10 so no
4(3)>10 = 12>10 yes
