Answer:
Mean of boiling times = 26.9 seconds
Step-by-step explanation:
Times ella recorded are given as;
24.5 seconds, 23.2 seconds, 29.8 seconds, and 30.1 seconds.
Now, we want to find the mean of these boiling times.
Formula for mean is;
Mean = sum of terms/number of terms
In this question,
number of terms = 4
Sum of terms = 24.5 + 23.2 + 29.8 + 30.1 = 107.6
Thus,
Mean = 107.6/4
Mean = 26.9 seconds

Answer:
y = -0.2x + 3.8
Step-by-step explanation:
it states it has been 7 weeks. 0.2 x 7 is 1.4. That means they started with 2.4 + 1.4 meters thick of ice sheet, which is 3.8, which is the number they started with. So, b = 3.8 and it says it melts 0.2 so it's a negative, which is -0.2 as slope. So, y = -0.2x + 3.8
