A = 122 degrees
Answer:
B. 57
Step-by-step explanation:
Given:
A regression line for some data transformed with logarithms predicts that when
To find what will the line predicts 
value when 
to nearest whole number.
Solution:
When
We can solve for by using logarithm properties.
<em>By logarithm properties.</em>
If 
Thus, we have:
∴ 
That can be expressed algebraically as x >714,587
Answer:
56% ≤ p ≤ 70%
Step-by-step explanation:
Given the following :
Predicted % of votes to win for candidate A= 63%
Margin of Error in prediction = ±7%
Which inequality represents the predicted possible percent of votes, x, for candidate A?
Let the interval = p
Hence,
|p - prediction| = margin of error
|p - 63%| = ±7%
Hence,
Upper boundary : p = +7% + 63% = 70%
Lower boundary : p = - 7% + 63% = 56%
Hence,
Lower boundary ≤ p ≤ upper boundary
56% ≤ p ≤ 70%
