Answer:
That guy is correct a because its both greater than and equal to 8
480 since 1 hour=60 minutes. Look on the graph and you can see that the line looks like its 500 but since the answer choices dont say 500 it has to be 480 which is the closest
Answer:
Part A:
Median value for Brand X = 13
Median value for Brand Y = 16
Part B: Brand Y has a longer battery life
Step-by-step explanation:
Part A:
Median value is depicted on a box plot by the vertical line that divides the rectangular box. Therefore:
Median value for Brand X = 13
Median value for Brand Y = 16
Part B:
Brand Y has a higher median value (16) than Brand X (13).
This implies that brand Y has a battery life that last longer than brand X.
The slope of the line connecting two points (<em>a</em>, <em>b</em>) and (<em>c</em>, <em>d</em>) is
(<em>d</em> - <em>b</em>) / (<em>c</em> - <em>a</em>)
i.e. the change in the <em>y</em>-coordinate divided by the change in the <em>x</em>-coordinate. For a function <em>y</em> = <em>f(x)</em>, this slope is the slope of the secant line connecting the two points (<em>a</em>, <em>f(a)</em> ) and (<em>c</em>, <em>f(c)</em> ), and has a value of
(<em>f(c)</em> - <em>f(a)</em> ) / (<em>c</em> - <em>a</em>)
Here, we have
<em>f(x)</em> = <em>x</em> ²
so that
<em>f</em> (1) = 1² = 1
<em>f</em> (1.01) = 1.01² = 1.0201
Then the slope of the secant line is
(1.0201 - 1) / (1.01 - 1) = 0.0201 / 0.01 = 2.01
