Hi,
The answer is c. The sample is biased.
This is because the sample is taken on a single state, an Rebecca reports a statistic about the nation. Her data contains information only of her state. If she lives in a very cold state, there is probably more homeowners using electric heat than in a hot state.
Answer:
<em>Answer: False</em>
Step-by-step explanation:
<em>Relations vs Functions</em>
For a given relation between two variables x and y to be a function, it must meet the following condition: every value of x must be related to one and only one value of y.
When the graph of a relation is given, we can easily tell the difference by using the vertical line test as follows:
Imagine a vertical line moving through the x-axis. If any line touches the graph of the relation at more than one point, then the relation is not a function.
If we place vertical lines through the x-axis, they would touch the function twice at some values of x.
Thus, the graph is not a function
Answer: False
They will need 2 more bagels to fill the final plate with bagels because 14*7=98 and 98-96=2
Two angles are supplementary if they add up to 180 degrees.
We have then:
m ∠ DAB + m ∠ ABC = 180
Substituting:
(85 - 2x) + (90 + x) = 180
From here, we clear the value of x:
-x + 175 = 180
x = 175 - 180
x = - 5
Let's try now that it is a parallelogram.
The opposite angles of a parallelogram are equal in measure:
m ∠ DAB = m ∠ BCD
85 - 2x = 80 - 3x
85 - 2 (-5) = 80 - 3 (-5)
85 + 10 = 80 +15
95 = 95
Answer:
x = -5
m ∠ DAB = m ∠ BCD (It is shown to be a parallelogram)

Mixed fraction formula: Quotient Reminder/Dividend
Q = 9 R=2 D=9
So, 83/9 in mixed fraction is 9 2/9
HOPE THIS HELPS!!!!
