Answer:
99.7%
Step-by-step explanation:
Note that 92 and 128 are 3 standard deviations from the mean
The emperical rule or the 68–95–99.7 rule states that 68% of outcomes are wihtin 1 standard deviation from the mean
95% of outcomes are within 2 standard deviations from the mean
99.7% of outcomes are within 3 standard devations from the mean
This is 3 standard deviations so the answer is 99.7
<span>(y-7) = 3/5 (x+25)^2 so the y intercept is -7 and the vertex is 35
</span>
54% of 630 = 0.54 * 630 or approximately <u>340</u> of the 630 were planning to vote for the candidate.
51% of 1010 = 0.51 * 1010 or approximately <u>515</u> of the 1010 were planning to vote for the candidate.
This means that the voter support for this candidate increased.
