A stereo uses 150 watts of electricity. How much CO2 is produced by using the stereo for
8 hours?
1.2 lb
0.2055 lb
1,644 lb
1.644 lb
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
mCO₂ = 1.188 lb or simply 1.2 lbHope this helps

Answer:
[tex]Pr = 0.66[/tex]
Step-by-step explanation:
Given
See attachment for complete question
Required
[tex]P(x \ge 5)[/tex]
From the attachment, we have:
[tex]S = 2 + 8 + 4+20+21+19+17+5+2+2[/tex]
[tex]S =100[/tex] ---- the sample size
Next, we list out all outcomes more than or equal to 5.
i.e.
[tex]x \ge 5[/tex]
5 is represented with the vertical blue rectangle (with frequency 21).
So, the other elements are to the right of frequency 21.
So, we have:
[tex]x \ge 5 = 21+19+17+5+2+2[/tex]
[tex]x \ge 5 = 66[/tex]
The probability is then calculated as:
[tex]Pr = \frac{x \ge 5}{S}[/tex]
This gives
[tex]Pr = \frac{66}{100}[/tex]
[tex]Pr = 0.66[/tex]

Millie has an interview for a job. She is driving to the interview. There are 3 sets of traffic lights on her route. There is a fifty/fifty chance of the lights being red or green.
What are the chances of Millie getting 3 consecutive green lights?
Answer: 0.125
Step-by-step explanation:
Since there is a fifty/fifty chance of the lights being red or green, therefore, the chances of Millie getting 3 consecutive green lights will be:
= (50%)³
= 0.5³
= 0.5 × 0.5 × 0.5
= 0.125
Therefore, the probability is 0.125

3+1, 3+3, 3+5
4+2, 4+4, 4+6
5+1, 5+3, 5+5
6+2, 6+4, 6+6
TOTAL combos:
36
TOTAL even sums:
18
so that means 18/36 or 1/2 of the possible combinations has a sum of an even number.

The median of the distribution of the class is 5 for the distribution 1,2,3,45,6,7,8,9,10
What is median?
The median is the central value of the data set.
How to find the median?
To find the median we have to use the formula:
If n is odd (n/2),(n+1/2)
If n is even (n/2)
Here the n is 10 so the median will be (10/2)=5
Hence the median will be 5 if the distribution is 1,2,3,4,56,7,8,9,10.

Answer:
x=2
y=√2
Step-by-step explanation:
You can tell from the angles that this is a 45, 45, 90 triangle. That would mean that the side given is x. Then the side "x" is x√2, and "y" is the same as x. So, that would mean the sides would be √2, √2, and 2.

(b) GJ
(c) KL
(d) 2 units
Step-by-step explanation:
For d, I divided 4 by 2 because a radius is half of the diameter
Answer:
Step-by-step explanation:
A diameter is IH. It passes through the center an touches the edge. A radius is GJ, because it starts at the center and touches the edge. A chord is KL, because it touches the circle at 2 points and doesn't pass through the center.The length of GJ is 2 units, because the diameter is 1/2 the length of the diameter.
Analia has $550 in her checking account. She wants
to spend part of this money on a VR-Headset. She
wants to have at least $225 left in her checking
account after buying a VR-Headset. The inequality
shown can be used to find t, the amount of money
in dollars that Analia can spend on a VR-Headset.
Solve the inequality.
t + 225 ≤ 550
Answer:
t ≤ 325
Step-by-step explanation:
the inequality: t+225 ≤ 550
t ≤ 550-225
Subtract 225 from 550
t ≤ 325 :)
