We will convert all units to degree Celcius in order to be able to compare the values.
We are given the following relation:
T(°C)<span> = (</span>T(°F)<span> - 32) × 5/9
</span>
Therefore:
Scientist 1 records a temperature of 1725 degree Fahrenheit which is equivalent to:
T(°C)<span> = (1725</span><span> - 32) × 5/9 = 940.556 degrees celcius
Scientist 2 records a temperature of 950 degrees celcius.
By comparing the values, we will find that the temperature measured by scientist 2 has a greater value.

the answer is Z. you can see the graph decrease first then increasing
Mean is the average number. To find mean, add all the numbers and divide by how many numbers there are.

There are 9 numbers. Divide by 9

Question 6 ⇒ C. 84.44
Median is the middle number when ordered from least to greatest. First order the numbers.

The 2 middle numbers are 10 and 11. Add them together and divide by 2

Question 7 ⇒ D. 10.5
Answer: 15x-14y=22
3x+5y=7
2.5x-y=17
42x+0.4y=15
Step-by-step explanation:
The standard linear equation of two variables x and y is given by :-
Ax +By = C , where A is a positive integers, and B, and C are integers.
Therefore, from the given options the linear equations that are in standard form are
15x-14y=22
3x+5y=7
2.5x-y=17
42x+0.4y=15
[-2x+8y=14 is not in standard form ∵ -2 is a negative integer.]
