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:
120
Step-by-step explanation:
40% of 80 is 40 so add the 80+40=120.
Hope it's correct.
Answer:
<em>(-8,4)</em>
Step-by-step explanation:
<u>System of Equations:</u>
Solve the following system of equations by the substitution method:
5x - 6y = -64 [1]
y = 20 + 2x [2]
Substituting y from [2] in [1]:
5x - 6(20 + 2x) = -64
Operating:
5x - 120 - 12x = -64
Simplifying:
-7x - 120 = -64
Adding 120:
-7x = -64 + 120 = 56
x = 56/(-7) = -8
x = -8
From [2]:
y = 20 + 2(-8) = 4
Solution (-8,4)
Answer:
11,36 pounds
Step-by-step explanation:
Trayvon's weight on earth= 142 pounds
Trayvon's weight on Saturn= (0,92)*Trayvon's weight on earth=
(0,92)*142=130,64 pounds
The difference between Trayvon's weight on earth and Saturn:
Trayvon's weight on earth- Trayvon's weight on Saturn
142-130,64=11,36 pounds.
