The data modeled by the box plots represent the battery life of two different brands of batteries that Mary tested. A) What is t
1 answer:
Answer:
X = 13 ; Y = 16
Median Y > Median X
Battery Y lasts longer and hence better than Battery X.
Step-by-step explanation:
From the box plot, median value is the point marked by the vertical line in between the box located between the whiskers.
Median :
Brand X = 13
Brand Y = 16
This median value depicts that, average battery life of brand X batteries is 13 hours while that of brand Y batteries is 16 hours ; Median value of Y is greater Than median value of X ;
This means Brand Y batteries lasts longer on average than Brand X batteries.

Answer:
Length of the bold arc = 72.63 ft
Step-by-step explanation:
Length of the arc =
Here, θ = angle subtended by the arc at the center
r = Radius of the circle
Since, angle subtended by the bold arc at the center = 360 - 73
= 287°
And radius of the circle 'r' = 14.5 ft
By substituting these values in the formula,
Length of the bold arc =
= 72.632
≈ 72.63 ft
Therefore, length of the bold arc = 72.63 ft
<h2>Explanation:</h2><h2></h2>
An irrational number is a number that can't be written as a simple fraction while a rational number is a number that can be written as the ratio of two integers, that is, as a simple fraction. So in this case we have the number 2 which is ration, and we can multiply it by an irrational number such that the product is an irrational number. So any irrational number will meet our requirement because the product of any rational number and an irrational number will lead to an irrational number. For instance:
