8 is missing for the table
Answer:
a) 0.54 = 54% probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both.
b) 0.46 = 46% probability that a randomly selected person will not feel guilty for either of these reasons
Step-by-step explanation:
We use Venn's Equations for probabilities.
I am going to say that:
P(A) is the probability that a randomly selected person will feel guilty about wasting food.
P(B) is the probability that a randomly selected person will feel guilty about leaving lights on when not in a room.
0.12 probability that a randomly selected person will feel guilty for both of these reasons.
This means that 
0.27 probability that a randomly selected person will feel guilty about leaving lights on when not in a room.
This means that 
0.39 probability that a randomly selected person will feel guilty about wasting food
This means that 
a. What is the probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both (to 2 decimals)?

0.54 = 54% probability that a randomly selected person will feel guilty for either wasting food or leaving lights on when not in a room or both.
b. What is the probability that a randomly selected person will not feel guilty for either of these reasons (to 2 decimals)?

0.46 = 46% probability that a randomly selected person will not feel guilty for either of these reasons
Answer:
Each sweater costs $8.30
Step-by-step explanation:
j = jeans
s = sweater
3j + 3s = 105.69
3(26.93) + 3s = 105.69
80.79 + 3s = 105.69
-80.79 -80.79
3s = 24.9
/3 /3
s = 8.3 ($8.30)
Check:
3j + 3s = 105.69
3(26.93) + 3(8.3) = 105.69
80.79 + 24.9 = 105.69
105.69 = 105.69
Hope this helps!
Answer:
No, Angela is not correct.
As the method Jim was performing will also lead to the solution.
Step-by-step explanation:
We are given first equation as:
Ax + By = C
Second equation is:
Dx + Ey = F
Jim solved the equation as:
He begins by multiplying equation (1) by D and equation (2) by A.
and so by subtracting both the equations he will obtain a value of y.
and then put the y-value in any of the given two equations to obtain the value of x.
Angela Method:
you should have multiplied equation (1) by E and equation (2) by B.
and when she will subtract both the equations she will get the value of x first and then when she will put the value of x in any of the given equation she will obtain the value of y.
But both will get a value for x and y.
Hence, the method Jim was performing was also correct.
We know that
<span>Each pie was cut into six slices
</span><span>there are a total of 48 pieces-----> divide by six to find the number of pies
48/6----> 8 pies
</span><span>Two of the pies will be served to members of the department as courtesy
</span>so
subtract 2 to the total of pies to find the pies available for sale
<span>whole pies available for sale=8-2-----> 6 pies
the answer is
6 pies</span>
