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
if we buy 20 pickles what is the experimental probability of winning 5 or more tickets
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]

A. 6
B. 7
C. 5
D. 8
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.

Marco gana 1200 mensualmente . La mitad de su dinero es entregado a su mama de lo que le queda gasta en la tercera parte en ropa cuanto dinero le sobra
Answer:
A Marco le sobra 400.
Step-by-step explanation:
Marco gana 1200 mensualmente. La mitad de su dinero es entregado a su mamá.
La mitad de un número se calcula dividiendo el número por 2. Por lo que la mitad de lo ganado por Marco se calcula:
1200 ÷2= 600
Por lo que Marco entrega a su mamá 600 mensualmente, y quedan 600, obtenido de la resta entre lo ganado mensualmente y lo entregado a su madre.
De lo que le queda gasta en la tercera parte en ropa. La tercera parte de un número se calcula dividiendo el número por 3. Entonces:
600 ÷3= 200
Entonces Marco gasta 200 en ropa. Por lo que resta es 400, obtenido por la diferencia entre los 600 que poseía luego de entregar dinero a su madre y lo gastado en ropa.
Entonces, a Marco le sobra 400.

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.
