Answer:
13
Step-by-step explanation:
The mean is the average of the data points.
(14 + 17 + 8 + 19 + 7) ÷ 5 = 65 ÷ 5 = 13
Answer:
mCO₂ = 1.188 lb or simply 1.2 lb
Step-by-step explanation:
We need to use the following expression:
E = P * t
Where:
E: Energy in Kwh
P: Power in Watts
t: time in hours.
Applying this, with the given data we have:
E = 150 * 8
E = 1200 watts . h
Converting this value in kW we have:
E = 1200 watts * 1 kW/1000 watts = 1.2 kWh
In general terms, we have 0.99 pounds of CO₂ emissions per kWh, so with the obtained value we have:
mCO₂ = 0.99 * 1.2
<h2>
mCO₂ = 1.188 lb or simply 1.2 lb</h2>
Hope this helps
Answer:
the statement is a true statement
F(x) = -4.3x - 2
f(g + 3.5) = -4.3(g + 3.5) - 2
f(g + 3.5) = -4.3g + 15.05 - 2
f(g + 3.5) = -4.3g + 13.05
-------------------------------------------------------------
Answer : f(g + 3.5) = -4.3g + 13.05
-------------------------------------------------------------
Answer:
a. 1
b. -5
c. -9
d. -2
e. 11
Step-by-step explanation:
a. -7 = 3a-10
-7+10 = 3a
3 = 3a
a = 1
b. 2a+13 = 3
2a = 3-13
2a = -10
a = -10/2
a = -5
c. -5a+14 = 59
-5a = 59-14
-5a = 45
-a = 9
a = -9
d. -23 = 4a-15
-23+15 = 4a
-8 = 4a
-2 = a
a = -2
e. -90 = 9-9a
-90-9 = -9a
-99 = -9a
-99/-9 = a
11 = a
a = 11
