Answer:
-3/2
Step-by-step explanation:
the formula for slope is y1-y2/x1-x2
where
y1 is the first point's y coordinate
x1 is the first point's x coordinate
y2 is the second point's y coordinate
x2 is the second point's y coordinate
so now we can plug our points in
-1-(-7)/1-5
6/-4
simplify
-3/2
The graph is a parabola with a vertex at -4
Answer:
Chebyshev's theorem guarantees that we will find at least approximately 89 % of the choir members between 46 and 70 inches.
Step-by-step explanation:
Chebyshev's Theorem states that, in a sample:
75% of the measures are within 2 standard deviations of the mean
89% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 58
Standard deviation = 4
Between what two heights does Chebyshev's Theorem guarantee that we will find at least approximately 89 % of the choir members?
Within 3 standard deviations the mean, so from 3 standard deviations below the mean to 3 standard deviations above the mean.
3 standard deviations below the mean
58 - 3*4 = 46
3 standard deviations above the mean
58 + 3*4 = 70
Chebyshev's theorem guarantees that we will find at least approximately 89 % of the choir members between 46 and 70 inches.
The number of pages which Claire should read each day to finish the 35 pages in 6 days is; 5.833 pages per day.
<h3>How many pages should Claire read per day?</h3>
It follows from the task content that the number of pages which Claire should read per day in a bid to finish all 35 pages in 6 days be determined.
Since the given condition is such that; Claire reads an equal number of pages on each of the next six days.
It follows that the number of pages to be read each day is given by;
35 / 6
= 5.833 pages per day.
Ultimately, the number of pages Claire should read per day over the next 6 days is; 5.833 pages per day.
